most important piece which is overlooked is lack of oil pressure. Shoot oil on grinding wheel with pressure of 30psi. which will allow more flow of thinner oils and may show lesser wear if more volume of thinner oil is disbursed over rotating disc.
The amount of effort and time you put into these videos for mundane everyday products is honestly unparalleled on the entire Internet. You sir are a hero for the everyday man.
When I saw that Jimmy Buffett passed away, I had my phone play "Margaritaville" while I got ready. I was in the shower when I heard some idiot talking, poked out my head, and it was an ad--after a 3-minute video, which had an ad before it. It was some young and fit guy telling me that I could answer a couple quick questions, learn my body type, and learn how to best lose weight. I answered some questions and he claimed that he just had a quick video to solve all of my problems--and talked for perhaps 30 minute. I got dressed, did 30 push-ups, and drove at least 20 minutes before the guy finally finished talking. 1. Carb cycling 2. Eat healthy fats 3. Do HIIT 3 times a week for 15 minutes 4. Pay him hundreds of dollars.

I feel a little bummed out on occasion when I made the "wrong choice" because I didn't know as much when I bought whatever than after watching these great videos. And I feel all smart and stuff when I found out that my pre-purchase research and purchase choice turned out to be the best one that I could have made, or at least the best one that I could afford to buy. This channel is the bomb!
What I love about this channel is he gets right to the point and no cringe intro and long explanations that are superfluous, it’s quick, coherent and easily understandable throughout the entire video and you never skip a part because it’s everything you need to know in every second. Not to mention there aren’t any cringe sponsors and what not.
@@ProjectFarm If you do another motor oil viscosity vs wear comparison, please consider making an equal parts mixture of 5W-20 synthetic and 5W-30 synthetic oils. If the wear scar decreases from that of the 5W-20 oil, but is also greater than the wear scar of the 5W-30 oil, then this empirically verifies that the wear rate of 5W-30 is not a fluke and that the wear rate is definitely better. Thank you.
As an Alaskan, I'd love to see the -40 oil put into the wear tester to see how they perform when put to work in extreme cold. If nothing else it'd be a great video to show the importance of winterizing your vehicle (Transmission heat pad, Oil pan heat pad, Block heat plug to heat coolant, Trickle charger/battery blanket). We tend to run thin oils here cause the winters are so cold. Fairbanks Area.
im still waiting to see the power steering video. I live in the Montana mountains, and -30 isn't uncommon; then add on I have a leak, and I want to see how different power steering fluids handle sadly I don't have the money or power outlets so I can winterize my truck in any helpful way bc I cant go out and start it up every day due to gas prices
An interesting thought, but I think it would make essentially no difference. Ya it'll start out at -40, but the friction will heat it up FAST. It's not like you wreck your engine with a cold/dry start one time, it's doing it hundreds, or thousands of times that gives you issues. I guess you could swap the wear part to a softer metal and perform a shorter test, to try and compensate?
9:32 The manufacturer doesn't always recommend "the best" oil, they will often recommend the oil that best meets EPA specs for mpg. Case in point, Ford's 5.4L 3-valve which officially calls for 5W20, but has incorrect pressure with it (too low) and works/lasts much longer when running on 5W30.
I love how nonchalant this man is. He has possibly the most positive comment section in the entirety of TH-cam in all of his videos and he always answers with a: Thanks! Never change 🗣️
Sure seems like the oil manufacturer added more additives to the 0w-16 to try and offset the increased wear of such a thin oil. Thank you for another informative test.
Unless the heavier rated oils stick to metal surfaces the heavier oil has a disadvantage when cold. With most wear taking place upon start-up the 0-16 has an advantage in this respect.
I'm retired but worked for a company that developed the micro-finishing film that most engine manufacturers adapted. There was extreme focus on the micro-scratch surface left by the finishing materials and very distinct to the design of a particular engine. There was much more engineering and research on this aspect than one might assume. When the manufacturer recommends a specific oil type and viscosity range, they have some well researched reasons for their recommendations. Modern, low-friction piston ring design also factors into what the manufacturer tells us we should be using.
@@DISOPtvexactly. Thinner oil gives better gas mileage. You’re trading off longevity for efficiency. The engineers only job is to build an engine that is more efficient than previous generations. That’s all they care about. They only need it to outlast the warranty.
Great to see someone finally put evidence behind the anecdote. Sacrifice a tiny bit of fuel economy and get a FAR longer lasting engine. I run 20w30 in my Ls1 statesman and it's got over 500,000kms on it. Doesn't burn oil, never smokes and has never been rebuklt
@damnnyiffers oil weight is just one factor. There is also how it is driven(harsh winters? Hot summers? lots of stop and go city driving? Lots of highway driving? Lots of idle time or very little? Etc), and oil change frequency.
@@steve8803 oil weight is by far the most important factor for conventional engines which do not specify 0w16 or lower. once you get into 0w16 the viscosity is not the most important consideration, bearing surface treatment technology reigns supreme.
My Skoda Octavia from 2018 has 200 000km and I am running 0W30, every 8000km change with all the filters. Runs like brand new - no smoke, no oil consuption, some friends told me "dude it can not be stock". Yes it is. I am adding Ceratec or MOS2 from LM on each oil change as well.
Friction reduction has seemingly lost to fuel efficiency when it comes to the purpose of oils. I still run "thick" oil in the summer and lighter oil in the winter, glad to know that lessons from Papa still hold up🤙
That logic checks out, I would be concerned about sludge buildup if you aren't really getting the engine up to operating temp for a sustained period of time. All oils do it, synthetic or conventional but synthetic seems to degrade worse in subpar conditions from what I've seen. Be well and make sure to keep your oil changes often and frequent...oil is cheap-ish while engines and repair bills are anything but🤙
I don't think "friction" as he tests it here really is how the engine sees friction. One thing he hasn't tested is "pumpability" when cold or hot. Probably way exceeds his method of testing for friction.
I could be wrong but I believe he has created a "backyard" version of the actual tests conducted industry wide🤷 With that said, the ability to pump the goo around at various viscosity levels is planned out heavily by manufacturers...unless you have minus 50°c for a month and freeze your coolant all should be fine under your hood👍

6:25 yes! Thanks for letting people know this. Also the "S" that they have dropped off the end (10w30s) stood for Summer. Before multi viscosity oils folks would change viscosities for hot and cold seasons.
I remember my previous car (a 04 Seat Leon Cupra R) having such a note in its manual. It had the old oils in it you needed to change between summer and winter and the newer multi viscosity ones.
Don't think anyone has ever commented on this, but the tight vocal editing, is always a plus point, and I appreciate it. Your videos are concise, informative, and still yet through.
I’ve set it before and I’ll say it again. Hands down best TH-cam channel I’ve found. No long intros, no selling merch, just straight to the point in under 10 min.
My last oil change on my 2016 Silverado, I mixed 0w-20 and 5w-30. The truck runs noticeable smoother. Next time it will be all 5w-30. Cold flow isn't a consideration as I live in the desert of Arizona.
I thought about doing the same on my JL wrangler... just to be safe.... After watching this video and forums.... My first oil change is coming up at 1500 and want to give it a head start on engine life by doing an early first change. And I live in Florida so it's rarely frigid here maybe a couple months of below 45* nights
@@wailingalenPersonally, my opinion on a new vehicle is to stay with the oil viscosity recommended by the manufacturer and what is says in the owner manual. Sometimes manufacturers will list more than 1 viscosity based on temps and usage, but usually it is just 1. If you use an oil that is not recommended and you end up with an engine problem under warranty, the dealer will void the warranty. And unfortunately today, manufacturers have more problems with new engines than you would think. Maybe you don't want to wait until the warranty is over, but it may be good to wait for a year or 2 and/or 15,000 miles or so... just to make sure. Also, if you can I would stay with the winter grade and only increase the grade for the hot weather viscosity. In other words, if it says 0W-20, think about 0W-30, or instead of 5W-20, go with 5W-30. You just don't want a high viscosity when you first start the car and before it is warmed up... I'm glad you are changing the oil at 1500 miles. Manufacturers say it is not necessary any longer, but I do that as well... Change the oil often and use a good filter; change fluids every 3 - 5 years or so; keep the air filter fresh; use fuel system cleaner (i like Chevron Techron); and drive it right... and it will last a very long time. I still drive a 22 year old Acura that runs like new with 238k miles on it..
Its important to remember that some newer cars have very thin oil galleries. Its not just about wear its about getting the oil through the galleries. If your oil is too thick and can't get through the galleries properly it doesn't matter how much wear protection it has cause your car will be getting very little oil on key components. .
We own a 2012 KIA Sorento, & a 2023 KIA Sportage. On the Sorento, I use 5W-30 in the cool months, & 10W-30 in the summer. On the Sportage, I use 5W-20 during the cool months, & 5W-30 during the summer months. BTW, we live at Puerto Rico, and summers get awfully hot.
Awesome test as usual! I still believe the CAFE requirements have a lot to do with manufacturer selection. Obviously, I would want a "thinner oil" in a very cold climate during start-up. However.... my 22-yr. old Buick calls for 10w-30 and I don't have any inclination to use anything else! Thanks for the tests!
I use 15-40 in the summer and 5-30 in the winter, both full synthetic. 320,000 miles and not a tick from the lifters and it doesn’t burn a drop. Leaks a bit but not enough to get worked up about. I have to top it off maybe 1 or 2 times between changes and I do 10k plus changes. And top it off means IT’s just touching the low line and I like it at the maximum mark. More oil equals better cooling from it.
I have used conventional/semi-synthetic 10w-30 in every vehicle I've owned in the last 21 years and have never owned a vehicle that didn't last 400,000 miles or more. I have done this regardless of the manufacturers specification. All of these vehicles succumbed to rust or driver-induced failure...no engine failed because of my choice of oil. That said, I changed my oil religiously at 3k or 5k miles (3k for conventional and 5k for synthetic). I also DROVE my vehicles. I beat on them and/or I drove them for significant periods of time to evaporate the condensation in the oil.
I used 5w30 in -30f and it worked fine. It started a little slow but I think that was more battery 0w30 felt about the same. I agree it is all CAFE even 0w16 cars here recommend 0w20 to 10w30 in other countries. People try to say the engine was specifically engineered for oil that thin. If it was then the manufacturer wouldn't also recommend 10w30. Engine clearances have been the same for a long time. Tolerances have gotten smaller (less variation) and the finish is better but the actual clearances are about the same. Todd's new truck having half the oil pressure also supports this, same size holes thinner oil = lower pressure. Companies care about profit and they lose money if they don't meet CAFE numbers. If thinner oil reduces total engine life but gets a better CAFE number of course they will do that. Next year CAFE is 51 mpg cars, 36.6 mpg trucks and 45 mpg combined. For every 0.1mpg under those numbers they have to pay $5.5 per vehicle produced. Miss the number by 1 mpg and you make 1.8 million cars (Toyota or Ford) thats $99 million dollars lost. Wonder why they are looking into 0w8 oil? Longevity is not always or is never the primary goal.
@@StephenDeTomasi Kurzgesagt is extremely educational, but 99% of what they teach is not actionable. This channel gives education that makes an impact on my daily life.
I love how you always explain the standards you are working against so every video can be watched as a standalone. Makes it easier to share the video with the folks I discuss them with.
Great test. I never run a 20 weight in a turbo charged engine but that's where the manufacturers are going because of CAFE averages. I realize you have to tell people to follow the manufacturers recommendations because of the liability issue but they really don't care how long your engine lasts as long as it makes it past the warranty period. VW had a 7 year or 70 thousand mile warranty before they switched to 0W-20. Then they dropped the warranty to 4 years or 50 thousand miles. They wouldn't have done that unless they don’t have faith in the oil they're recommending.
Exactly what I was saying yesterday. Glad others are catching on the gimmick. Also don't trust the engine oil life indicator light. Just use full synthetic engine oil and change it at least twice a year even if you don't drive over the mileage limit.
VW has a 6/72K warranty for only 2018 and 2019 model years. They did it to help potential buyers feel good about the company again. Remember that they got caught cheating on their diesel emissions. They were fined and had to buy back cars from their customers (or provide other remedies). It had nothing to do with 0W20 motor oil. If you look at the reason VW motors fail, it's not for lack of lubrication. Most times it's due to overheating. Their cooling system is overly complex and there are many places a coolant leak can occur. I've blown up two 2.0L VW motors in the past 4 years. Coolant leaks and runs low, then the motor overheats. Of course not temp gauge, so by the time the dummy light comes on, the motor is cooked!
@kanyeeastlolz Yes, Minnesota actually. All my vehicles.. every 3300 miles. So 10k miles, change it 3 times. Then, every 10k, rotate tires and drain trans oil (trans pan drain plug 4 quarts come out). It is sooo cheap to do this. I'm 65, retired, my dad taught me this since high school. I have always used Castrol gtx non synthetic. Just my .02 sharing.
@@ronlind1757 Conventional oils do fine at 3k mile oil changes, but, Supertech full synthetic is $18 for 5 qts, and you can easily go 5k OCIs. It's also a superior oil, I don't waste my time with anything not full synthetic.
The most important part of the video was at the end differ to the OEM recommendation on oil viscosity. Don’t just throw a 0w16 at your engine if it calls for a 10w40. If you live in a hotter climate use the higher viscosity of oil recommended if it’s colder vice versa. The only thing you should probably take into question is the oil change intervals especially with forced induction engines.
You can not appreciate this mans attention to detail enough until you've seen hundreds of videos trying to be scientific but failing miserably. No 'whats', 'ifs' and 'whens' were left behind. The questions posed are always answered and in a short and to the point manner. You, Sir, are very appreciated. Thank You!
When you do oil tests it might be interesting to include the all-time best and worst performers on the charts at the end of each test (maybe give them a faded out color to set them apart). This would give some overall context to the small selection being tested.
Toyota is now using 0W8 in the new hybrid engines, BMW is also using 0W12 is some of their new ones too. Crazy! Even more important to keep the oil fresh in those engines!
Additives make a huge difference on wear. It would be interesting to also do a test with bearing material instead of, or in addition to, the test wheel & pin you are using. I'm pretty sure that is what oil companies tailor there additives to.
Valve lifters/tappets,cam lobes,piston rings/upper cylinder walls,also timing chain links/rollers. Ball pivots used under rocker arms and pushrod tips. Some cam drive chains and sprockets may be larger/better than the minimum practice,also some modern engines use "roller lifters" to try to reduce demands on lubrication but then there is the axle that the roller rolls on ! The oils are constrained by the fact that the EPA does not like a lot of antiwear additive(s) because of the idea that if the engine is burning a bit more oil than desirable the additive might poison the catalytic converter. I believe EPA has even found a way to spread that to Diesel engine oil requirements. So that obsolete SG rated oil from a few years ago may have had better antiwear performance under adverse conditions than today's oils although such standards as "GF-6" or "GF-6A" are an attempt to come up with oil that will offer adequate protection even with the EPA not allowing much of traditional antiwear additive. I believe the super long oil change distances being advertised by the car makers today are pushing the oil far beyond what is safe. I believe that the additives wear out. A broken in engine is easier to lubricate in my opinion than a brand new one. ideally the connecting rod and crankshaft main bearings are "floated" in oil most of the time that the engine is running.
What I’ve always found interesting is how manufactures recommend different weight oils for identical vehicles with identical engines in different markets. For example my SVT Focus is recommended 5w-20 in the USA but 5w-30 in Europe. My Mazda Skyactiv-G 2-5l NA is recommended 0w-20 in USA and Canada, and 0w-16 in Japan, which has almost identical climate swings to the continental USA, and interestingly, 5w-20 in Mexico, which presumably doesn’t even need Winter-certified oil, or thin starting weight for that matter.
@@Broeils wow, never actually thought about that but you’re probably right. Good chance the regulatory bodies in different countries have different standards.
@@emotionz3 there's also different emissions regulations in different areas, and oil choice can impact emissions testing, and they probably have to test with the recommended oil.
@@emotionz3 No, the oils sold have the same composition - if they are meeting the same standards. And since they are shipped World Wide - such and such Penzoil Platinum Full Synthetic - 5w-30 will have exactly the same spec's anywhere.
@@daves7775 Many manufacturers order their oils in local refineries. Unless they control every batch, you do not really know if the oil meets the original specs. Only few companies produce their oils 100% by themselves and ship it worldwide
Another great video. I'm old school and always thought a thicker oil was the way to go but I'm changing my thoughts a bit on the matter. I was always a 15w 40 guy in everything even small engines. I've never had an engine fail using it but sometimes colder starts were a problem. Then the 5w 40 diesel oils came out and I slowly switched everything to that. Boy did it make a difference in everything especially the diesels. I've come to the opinion that unless the engine is under maximum load and at high temperature all the time the thicker oils may not be necessary. Also oil pressure is an indicator of resistance to flow. So low oil pressure doesn't necessarily mean the engine is not getting oil. Engineering is constantly trying to improve fuel economy and I think that is a major factor, but also I think modern engines using thinner oils have a much higher oil pump volume to try to keep things cool. It's hard for an older guy to get his head wrapped around a 1.5 4 cylinder stock engine producing 250+ hp. Most all auto engines have oil coolers today and that says something. More power in a small package turning higher rpms and a turbo or 2 make a lot of heat and thinner oils flowing faster pick up more heat and carry it away for cooling . Sorry long winded but I'm always trying to learn and understand
newer engines usually have a cylinder that's purposely designed to be micro porous, it means they actually hold onto thinner oils but struggle with thicker ones, couple this with reduced friction piston rings, tighter journals , oil passageways and bore sprayers designed specifically for thinner oils to flow through them it makes it a bad idea to put thicker oils in them. Even though the thicker oil itself is technically a better lubricator when put in a modern engine it actually lubricates worse and can potentially even cause issues. Another thing to note is that a lot of new economy engines are direct injection which usually results in more carbon build up around the valves over time so using a thicker oil with less additives could increase the amount of carbon build up over time.
@@axeami1354 this all makes sense but then Toyota will specify 5w-20 in Europe and 0w-16 in the US for the same engine. If everything else were equal wouldn’t it make sense to equalize the oil specifications? Others reflexively scream CAFE but I’m not so sure
@@tjm3900 exactly, it warms the oil in cooler weather. Also aids in bringing engine up to stable temperature. I was going to mention it but I figured I was a little long winded as it was
Very interesting! As an old timer it's hard for me to wrap my head around the idea that you should use the same 0w-20 motor oil whether you live on a permanent glacier where anything above freezing is considered a heatwave, or, like myself, you live in desert where you put on a sweater when temps drop below 80. I'm going to need more than just a manufacturer recommending that, because as an ex dealer tech I've seen manufacturers recommend some pretty stupid things over the years. Things that are designed to make them money, not extend the life of the vehicle. And before y'all start typing, remember that oil temp and coolant temps are NOT the same thing.
If you open your owners manual it will have alternate oils than what's on the cap. My 18 f150 says 5w30 on the cap, but in the manual 5w40 is still in the temperature range... (although 5w30 would be better for me in winter).
If you run a block heater 24/7 then your engine never cools down and your oil doesn't break down the viscosity I can get 10,000 miles between oil changes if I use a block heater
You should have more subscribers than those mindless “ influencers”. You’re videos are thorough, and the normal individual would never be able to spend the money to test the unending amount of products you test weekly. Thanks man… love the videos.
One of the greatest services provided by this gentleman is encouraging people to think critically and objectively. These videos belong in every engineering curriculum.
I switched to 5w30 from 0w20 last year. Mobil 1. Car makers want higher mileage numbers at the cost of the engine. I also change my oil often and earlier than recommended. I live in the South. No cold weather. Good test. Thank you
@@moshet842 With an air cooled engine in 25c+ weather, I'll stick to using the higher viscosity. There may be not much of a difference, but the 10w40 oils here in the UK are considerably cheaper and have slight better protection. It's a no brainer.
This channel should be considered a national treasure. not only can I not tell you how many PF videos I have watched, but I have watched MANY of them more than once. Such a good channel. Another well done video much appreciated!😊
I believe Project Farm is recognized unofficially at least as the goto for product test results because of his scientific method, testing multiple ways, and objectively stated results.
Lighter weight oils are only used to squeak out some slight efficiency gains. They just don't provide as much protection to the engine components as the traditional 5w-30 oil (as the bearing test clearly showed) and thinner oils will sneak past seals and cause the engine to start burning oil and piddle on your driveway a lot quicker than 5w-30. If you ask the EPA; apparently burning oil and nuking an engine prematurely is fine and dandy as long as you can save 1/2 mpg in the process.
yes, i still use 10w40 oil and it is maybe most used here in finland, 5w40 is better for daily use in winter time but... i saw how it turns in 2 years without oil change.. it was like water lol :D
When you have a chance, watch a video on the new Toyota 2.5L motor that I think was the first to use 0W16. They have been using this oil in Japan for a while before it came to the US. With Toyota's tight tolerances and low friction motor, I believe 0W16 has more than enough viscosity for their motor. If it didn't, you'd see quite a bit of metal in the oil and oil filter, which isn't the case.
As shown on the bearing test the 5W-30 had the least amount of wear. Protect your engine. The only reason the 5W-20,0w-20 and 0W-16 exist is due to the EPA push for higher mpg standards. I had relatives working at auto factories that saw the EPA reports mandating it.
I was wondering about that. My 2014 Toyota Prado lists a range of oils to use given the max/min temperature, and you can basically use anything when in the range of 0-40 deg. c
I believe hybrid vehicles especially plug in hybrids require thinner oil. Since the engine is not always running, thinner oil flows better at lower temp
I have a question though. Does engine wear happen mostly when cold starting? And if it is so, what kind of tests would reflect the effects of viscosity on engine wear? An idea comes to mind, start/stopping the wheel 100 times without pre-oiling them. Would that be more reflective of real world circumstances?
It only makes sense that a thinner oil will provide less protection from wear. I always used 10W30 (I'm 81 and pretty set in my ways), but I have never had car that called for these thin oils. My vehicle is a 1995 Jeep Grand Cherokee with the straight 6 cylinders. It has 240,000 miles on it and I have only used 10W30 in it, which is getting harder to find.
My understanding is that most of the wear occurs on a dry start up, before the oil arrives to the overhead valve train. That's why the friction tester wheel is coated with oil prior to testing. Wouldn't the much faster cold flow of the 0W-16 more than compensate for the decreased wet protection? Especially in vehicles driven short distances?
There's a large factor that never gets discussed, and that is thermal expansion. An engines machined clearances are tested and engineered to be correct --- at full temp. The bearing clearances are effectively incorrect at cooler temps, and accounts for much of start up wear.
Have you heard valvoline's new oil's claim to "restore pistons to factory clean" and protect them. That's a bold claim. Would love to see how they are against your top 2, amsoil and pennzoil with standard mobil 1
@@ProjectFarmPlease test this oil. I would like to see the collection of particles in the oil filter. That is the biggest concern I have heard of on a dirty engine. If you test it split and weigh the oil filters! Love your videos👍
It will on an 07 yaris made for 5w30 when you somehow manage to not only grab 0w20 but to put it in and run it. Instant oil glitter, but after 5k miles of 1000 mile oil changes with cheap conventional 5w30, it didn't even knock.

Discovered you a few days ago after buying a used car. Practically every product purchase I consider for this car I now vet through your channel because you are so damn good and thorough. Can't thank you enough! In a YT sea of deception, obfuscation, and ENIGMA-level deciphering, you are a clear and trusted island.
Dear Project Farm, Thank you for the informative videos that have real world application. If I may suggest the following: 1. Calculate the weight loss due to evaporation as a percentage of the total initial weight. 2. Weigh the pins before and after and calculate percentage lost due to wear. I look forward to many new videos.
The MAIN thing is to have all the oil you need in the engine. It helps if it's clean. after that it's just a fine point on a sharp pencil. I drive older stuff, with plenty of clearances, and the runny numbers "evaporate" most quickly from the crankcase, plus it rarely gets super cold down here. Good video.
My older vehicles definitely run thicker oils, However even my high mileage newer vehicles use factory spec. So many newer engines have such small oil passages that thicker oils restrict flow and cause starvation. Sucks because other parts with wear clearances could sure use the thicker stuff.
I tried 20W50 in an old '79 Plymouth Horizon I had. The engine needed a valve job and was burning oil. One day the temp dropped and the starter could barely turn the engine over.
Can you test, say, 10w-40 for lubricity and puring viscosity, example @ 30 degrees Celsius , and then test the 5w-20 @ 10 degrees Celsius also for lubricity and pouring to see if acts the same as the 10w-40 @ this temperature , or @ what temperature will be the same
When we first got a carton of 0W-16 oil at my shop, I didn't think it was for a normal daily driven vehicle. I though it was some specialty performance oil for a 2 stroke or something. Just goes to show how much closer the tolerances are in these newer engines. I drive 20+ year old Japanese vehicles and run 10-W30 in them with no issues. It helps that it rarely gets below freezing here.
always hear that term "new tight tolerance engines". but in reality pretty much all tolerances have been the same since the 90s as far as japanese engines go. also the reason the idle oil pressure on his 2020 is so low at idle. same bearing tolerances but lower viscosity oil.
Love the channel but the oil stuff is pretty much beaten down. Hes probably done a dozen over the years and you can only test so much additives and hot/cold viscosity.
It also doesn't make sense to use the total weight lost since the starting weights are never exactly the same. Percent lost is the what we actually want to know.
"Best Foam Sprayer Pump-Bottle Cheap vs. Expensive" -there's some that boast quality assembly, i.e. durable parts and secure pressure after hand pumping soap contents, others that boast versatility toward multifunction like garden sprayer nozzle adjustment option. Thank you for always answering with such thorough tests!
Started using a synthetic 5W-30 in the mid 1980's. My dad said I was crazy to put such a thin oil in my car! After about 200,000 miles I gave him the car and he drove it for years.
As you said in the very end, use what the manufacturer calls for. Bearing clearances are getting tighter than ever and if you use a 5w-30 or higher in something designed for 0w-20 or 0w-16, you might not be getting good oil flow to each area of friction, and the same can be said if you use thinner oil when it should be thicker. Extreme climates might change what you want to use though. But most of your wear will be a result of choosing to go way too long without changing your oil, especially on engines notorious for burning it. 5,000 miles max since modern engines use oil to do so much more than just lubricate the crankshaft and camshafts. I feel like I started a war here. The oil consumption is generally from low tension piston rings, but some engines are notorious for this being a severe problem where others it's just a meh issue. There are additives out there that go in prior to changing the oil to "dissolve" hardened oil deposits that cause those rings to stick. Just change your oil regularly and learn to check it yourself so you know if you're low or not, your favorite in and out quicklube is just going to drain and refill, they dont check for that stuff.
I'd tend to agree. Originally I discovered that Ford specified 0W20 to assist in passing EPA fuel economy tests, so I then began using 10W30 in vehicles that were spec'ed at 0W20 with zero issues. This was a deliberate decision on my part after significant research to guard against excessive wear. Fast forward a couple decades, and I tried the same thing in a 3.5l Honda Odyssey...BIG mistake. The bottom end on the Honda 3.5 would take the thicker viscosity just fine, but the oil passages in those VTEC heads certainly couldn't, and complained with a significant amount of clatter on cold starts. I'm trying to get the thicker oil flushed out but 2 changes later the valvetrain still clatters a bit on cold starts.
So for your next car people find a car with an engine that is port/direct injection as well as something that uses 5w30 oil so it does not wear as much
Remember y’all, some parts of the world don’t even have 0W20 for the same engines! If you look at oil charts for various makes and models you’ll see it everywhere from 0W20 here in North America to a 50wt in the Middle East. The “ideal” viscosity for protection and cold and hot flow is 5W30 (North America). Ford never changed their engine designs in the early 2000’s. The CAFE dictated and oil companies sold to them and they retested their engines on 5W20. The same reason why BMW M engines had rod bearing failures running 10W60 🙈. It’s not “clearances” that matter what matters is protection. 5W30 is already pretty thin…
It would be interesting to see a comparison between some of the newer "Hybrid Engine Oils" (Mobil1, Valvoline) compared against their "Regular" variants. Maybe add some tests with impurities/fuel dilution to see how they hold up? Always love your content!
It all depends on bearing tolerances in the engine of which you're using the oil . Always use the oil viscosity that the manufacturer recommends . If you have something rebuilt and the crank bearing tolerances have changed then you use a slightly thicker oil . My .0010 under bearings made the viscosity change from 5W30 to 10W30 in one of my engines . The oil has to be thick enough to be able to form a proper hydrodynamic wedge between the bearing and it's cap yet thin enough to flow easily and quickly .
It would probably be very difficult to do, but being able to test wear resistance while the oil is very hot would be cool. Them being at room temperature is closer to winter viscosity than hot viscosity. I wonder if they would be closer at those higher temps.
I'm just glad you specified to stick to the recommended oil per car as my dad failed to do that in one of my first truck and ended up clogging up my oil pump and the pumps intake screen because the oil was to thick and started sludging up within a 3000 mile range
We dont use all this thin oils in eu all cars i own use 0-30 or 5-40 + there is no point using to thin oil if u dont live in extreme cold climate. Now days summers are so hot so 5-40 is better for protection
I think it would be a good video to test all 4 oils in your truck. Run 1000 to 3000 miles then do a oil sample test after each oil! Thanks for all your hard work!
I sent my Italian Iveco 6 cylinder Turbo charged diesel engine using Ams Oil 15-40W diesel with a by pass oil filter system that was like 2or3 microns. I sent my oil sample in at 15,000 miles it came back with a clean bill of health, I the tried the same oil at 25,000 miles and it was still OK? The trick was I changed the engine twin oil filters at about 7,500 miles and I kept the 3 or 4" diameter by about 12" inches Ams by pass oil filter till only one half of the filter was still hot and the other half much cooler? An engineer taught me that trick as that large oil filer was very expensive my engine went 350,000 miles when I parked it 20 years later as finding parts were very hard to get in the United States. I find it Odd the the same engine and Turbo charger was still good when I parked the truck?
Yes, because the test will show more results on where and tare. What components are worse. The 30w wate should be better for where. 16w whatever seems to thin depending on how hard you run your vehicle's.
@@77.88. I do the same on my Chevy cruze. It maybe where'd but it beats changing my oil like a idiot every 3,000 miles. I only do it once a year. It's the best feeling ever. Lots of pride saying so too. I run amsoil signature series 0w20
Most, if not all, new Toyotas require 0W-16, I'd never seen that oil weight before getting a '19 Camry. They're pretty strict, too - if you don't have 0W-16, you can use 0W-20, but must return to 0W-16 at the next oil change. Unfortunately, at least around where I am, only the dealer has 0W-16 available. Seeing how free-flowing the 0W-16 is, I can understand why it's recommended for use - Canadian winters can be cold!
Did that older truck have low tension piston rings, or GDI? If it's older than say the 90s, they didn't. So these newer cars will need that crap 0w20 in the winter, and it's probably safe to use 10w30 in the summer, I do...
I think you said it best at the end. Your recommendation is to use the oil the manufacturer recommends. I'm old school and my car calls for 0-16 oil. It's hard for me to do, but I do.
But an engine block heater makes that a moot point as the oil won't be -40. Also it should still be coated from the last time it ran, unlike in the test where it gets cleaned between uses.
@@Dr-TH-camwhat hes saying is also test the cold oil from 0°F not just warm new and -40 because a majority of people arent going to see -40 temps where they live
Blows my mind that all hybrid powertrains recommend 0w20 - 0w16 for the engine side assist. Looks like ill be blending some 5w into mine. Thank you for getting right to the point with tangible results and sharing it with everyone. ❤
Not just for efficiency, hybrids especially plug in require thinner oil. Imagine this, you’re stuck in traffic for a while and only using electric power. Once the traffic is clear and you put your foot down, the cold engine kicks in for power. But the thick oil doesn’t flow quite easily as the thin oil does when cold, you end up damaging the engine even more
@@Dankboi420 if you love in the cold sure everywhere south of the mason Dixon line here in the states is usually above 30 degrees after spring they never go below 80 in Texas until winter
I have done a small amount of research on oil weight and have come to the conclusion that a lot of manufacturers will use thinner oils in the same engines just for the fact that the EPA wants tighter fuel economy numbers. My current vehicle which has the same engine in Europe and South America uses 0-20 here and 5-30 everywhere else. I believe that even tho thinner oil causes more wear as you have also proven it is a trade off for fuel economy. I have currently switched to 5w30 which the owners manual does say is acceptable for towing and extreme usage. Even tho the cap says different the manual does say thicker oil “can” be used and is acceptable as it is used in other countries as well! Thanks for the great video!
@@swimers100i run 5w20 in the pentastar. As we see in these videos 5w20 shows significantly less wear! Also no lifter chatter at start up even at -10 degrees. I run 5w30 in the hemi
After Brian at FordTechMakuLoco recommended full synthetic 5w30 (he likes the penzoil platinum full synthetic) for my F150 with a 5.4L 3V engine, I definitely switched over from the factory-recommended 5w20 blend. He likes the heavier oil because it sticks to the rockers and other parts in the top of the engine.
Thats why i switched in my jeep wrangler with the 3.6l pentastar, they are known to have some oil filter housing and rocker arm issues. I think the heavier oil will help out! They magically switched in 2013 to the 5w20.... probably for fucking CAFE gas mileage bullshit
This is a great channel! As someone who builds race engines for a living I would strongly suggest staying with the recommended oil viscosity. The clearences in modern engines are very tight compared to 10years ago. Going from 0W16 to 5W30 can cause accelerated wear on bearings, piston to wall issues and piston rings. Great test, keep them coming please.
@@edbaczewski2959 I love how people are always looking for any reason why low viscosity oil is better. The truth is that it is not because viscosity is always closely related to lubricating properties. In the eighties, the standard was 15w40, in the nineties, 10W40, etc. And everything worked great, including the variable valve timing, which was recently 50 years old, even though the world only knows it from the end of the 80s. Since then, every car manufacturer has named it after themselves, for example Vanos from BMW. .
Hey Todd, have you thought about doing the bearing test AFTER freezing the oil? It would be interesting to see how each oil performs on a bearing when frozen.
I've wondered that. The thing is, once you actually get to the testing part, the oil has warmed up. You've got a good idea, but it might be difficult to test.
Miss the oil test videos. I know you can only test so much so many different ways but glad to see another classic from you Project Farm. Love the oil test videos 😂❤
Thanks for all the effort you put in your videos, maybe you can include a 20W-50 and 15W-50 in a future video, here in Brazil 20W-50 is very common because of older cars and hot weather.
Same here in South Africa. I would also like to see how the oils in this video do at high temperature on the wear tester. To simulate using it in 30-40 centigrade.
Awesome content as always. One word of caution though. The OEM oil pressure gauges on cars are not always accurate by design. Some operate like on/off switches and are there to just report any pressure. As an example miatas are notorious for this.
I love all your videos it’s definitely helped me make some buying decisions in the past. Just a suggestion though I’d love to see you add the bearing test with the cold oils to the videos. Best way I could think to simulate starting your car in the cold of winter and letting it warm up before driving.
The high wear rates in a real world engine when it is cold are likely due in part to the presence of condensed water and liquid fuel removing some of the oil film from engine wear areas. Especially the upper cylinder and piston rings. @@ProjectFarm
Great video. Because VVT and oiling systems in vehicles are getting a lot more sensitive, it is important to use the oil the engine was designed for. Even if it seems too thin. I am a Toyota mechanic, a lot of the newer Toyotas are going to 0W-16. They started around 2018 with the Camry, and since then I’ve seen several get to 200,000 miles and they don’t burn a drop of oil.
I use the recommended 0w16 in my 2021 Corolla 6spd hatch. I use 80W90 GL4 (not recommended) for gearbox oil. I haven't had any issues. 75W seems like a waste of money if you change it out every 25k miles.
@@corruption1724 From listening to engine racing techs, they said you use a thicker oil because it becomes thinner as temps rise and act like a thinner oil. I would believe if you are just driving back and forth to work and store you wont have to worry too much tho.
- Indeed. Under normal driving conditions and of course with proper maintenance of the car, we should not worry too much about the oil if it matches the specs. In my Beemer X5 3.0D = Shell Helix Ultra, it is equivalent to the Penz. Furthermore, I only recommend XL Boosted from Amsoil, absolutely top quality, smoother engine, visco is maintained, temperature of the engine remains optimal. Etc. To buy!@@wanglee21
I love your videos there’s no beating around the bush always straight to the point. I rely on your testing before I buy anything. Thank you brother for the honesty 💪💪🇺🇸🇺🇸🇺🇸🇺🇸
Thanks for running these test. My 2010 Honda element calls for 5w20 but have only used it maybe twice since i bought it new. I use 5w30 in it and my 2004 Nissan Titan as i don't think the 5w20 provides enough protection when it gets to be 110 down here in Texas. Oil shears down so that means the 5w20 will be even thinner after a few thousand miles. We don't usually see below freezing temps here so i don't worry about that. I normally use the Pennzoil ultra platinum not burning any oil with over a 150k on the little Element. I don't wait for the maintenance minder to come on i change at 5k or sooner. Oil test may say it still good but they don't test how much dirt and soot is in it.
I have been asking myself this question with all the 5W-30 oils that are recommended just to save the tiniest bit of fuel compared to the 5W-40 that I usually use, especially in older engines (I have a Benz and an F-Body from the 90s).
on new cars, the thin oil is really important. older cars, it's not such a big deal. apparently the new cars have thinner channels and avoiding all the technical jargon about how the oil is circulated and distributed, basically using a thicker oil in a 0w-15 recommended car is like using axle grease in a 10w-30 recommended motor. running dry for longer at every start, causing damage. it probably does save fuel, but it's not the only reason for the change over time. hope this helps out somehow.
Now the 5w-30 is actually considered thick ! I believe that some of this spooky thin oil stuff is driven by car makers trying to avoid CAFE penalties,that would explain the different oil viscosity required in different countries in the same engine. I think only with synthetic oil technology can even the 5w-30 oils and 0w-40 oils be made that won't fail miserably in use. One thing to remember is that the same horrible technology that Cadillac used to call "V8-6-4" is back,it requires rapid flow of oil upon the command to pump up or collapse valve lifters and engines that have that may malfunction unless using spooky thin oil. Also known as "displacement on demand" or "cylinder deactivation" I think some cars from Honda,GM and Chrysler/Dodge are using it to meet CAFE
It‘s an awesome video as always. For the car guys, keep in mind that modern cars are usually equipped with an oil-cooler that helps keeping the viscosity stable and the evaporation rate low. That results in different operating conditions between the low viskosity stuff and the multi-grade stuff.
Oil cooler isn't gonna do much to the extreme temps the oil sees above the oil control ring. 0w-16 and 0w-20 is all epa bullshit so cars can get like 1 mpg better at the expense at blowing up right after the warranty expires.
Just for consideration, that late model Chevrolet showed in your video does not use an actual oil pressure gauge, but a “dummy” gauge which is programmed to stay at an approximate position as long as the pressure sensor sees X_psi minimum.
@@duramax74 heck my Colorado does not have an oil pressure gauge at all, well it has one in the trip computer on the cluster but not a needle like my 1995 S-10 did.

can you do wear test at 40F to get an idea which one wears out most at cold start up ?
most important piece which is overlooked is lack of oil pressure. Shoot oil on grinding wheel with pressure of 30psi. which will allow more flow of thinner oils and may show lesser wear if more volume of thinner oil is disbursed over rotating disc.

@@ProjectFarm If you do another motor oil viscosity vs wear comparison, please consider making an equal parts mixture of 5W-20 synthetic and 5W-30 synthetic oils. If the wear scar decreases from that of the 5W-20 oil, but is also greater than the wear scar of the 5W-30 oil, then this empirically verifies that the wear rate of 5W-30 is not a fluke and that the wear rate is definitely better. Thank you.
@@ProjectFarm keep up your great service... from Asia
As an Alaskan, I'd love to see the -40 oil put into the wear tester to see how they perform when put to work in extreme cold. If nothing else it'd be a great video to show the importance of winterizing your vehicle (Transmission heat pad, Oil pan heat pad, Block heat plug to heat coolant, Trickle charger/battery blanket).
We tend to run thin oils here cause the winters are so cold. Fairbanks Area.
Thank you for the video idea!
im still waiting to see the power steering video. I live in the Montana mountains, and -30 isn't uncommon; then add on I have a leak, and I want to see how different power steering fluids handle
sadly I don't have the money or power outlets so I can winterize my truck in any helpful way bc I cant go out and start it up every day due to gas prices
Yikes I can imagine how cold it gets up In Alaska… I’m from the upper Midwest and luckily it still 95° here. 😅
An interesting thought, but I think it would make essentially no difference.
Ya it'll start out at -40, but the friction will heat it up FAST.
It's not like you wreck your engine with a cold/dry start one time, it's doing it hundreds, or thousands of times that gives you issues.
I guess you could swap the wear part to a softer metal and perform a shorter test, to try and compensate?
How do you survive up there? As a Canadian, I can get used to -30⁰C
9:32 The manufacturer doesn't always recommend "the best" oil, they will often recommend the oil that best meets EPA specs for mpg. Case in point, Ford's 5.4L 3-valve which officially calls for 5W20, but has incorrect pressure with it (too low) and works/lasts much longer when running on 5W30.

Sure seems like the oil manufacturer added more additives to the 0w-16 to try and offset the increased wear of such a thin oil. Thank you for another informative test.
Exactly!
That’s what Toyota uses and they are known for reliability and longevity
Unless the heavier rated oils stick to metal surfaces the heavier oil has a disadvantage when cold. With most wear taking place upon start-up the 0-16 has an advantage in this respect.
@@michaelbassett5105 Honda uses 0W16 on some models I think I heard as well.
Efficiency is good when you own it, longevity is better for the next owner
I'm retired but worked for a company that developed the micro-finishing film that most engine manufacturers adapted. There was extreme focus on the micro-scratch surface left by the finishing materials and very distinct to the design of a particular engine. There was much more engineering and research on this aspect than one might assume. When the manufacturer recommends a specific oil type and viscosity range, they have some well researched reasons for their recommendations. Modern, low-friction piston ring design also factors into what the manufacturer tells us we should be using.
Thanks for the feedback.
You said what I came to say.
EPA probably is the most reason for the low vis oil and high mile oil change intervals.
@@DISOPtvexactly. Thinner oil gives better gas mileage. You’re trading off longevity for efficiency.

Thanks!
@damnnyiffers oil weight is just one factor. There is also how it is driven(harsh winters? Hot summers? lots of stop and go city driving? Lots of highway driving? Lots of idle time or very little? Etc), and oil change frequency.
@@steve8803 oil weight is by far the most important factor for conventional engines which do not specify 0w16 or lower. once you get into 0w16 the viscosity is not the most important consideration, bearing surface treatment technology reigns supreme.
My Skoda Octavia from 2018 has 200 000km and I am running 0W30, every 8000km change with all the filters. Runs like brand new - no smoke, no oil consuption, some friends told me "dude it can not be stock". Yes it is. I am adding Ceratec or MOS2 from LM on each oil change as well.
Friction reduction has seemingly lost to fuel efficiency when it comes to the purpose of oils. I still run "thick" oil in the summer and lighter oil in the winter, glad to know that lessons from Papa still hold up🤙
Thanks for sharing.
I lived in Ohio. I had an 85 Ford F250 with the 6.9 IDI diesel engine. Ran 20w50 in the summer and 10w40 in the winter. No blow by 👌🏻
That logic checks out, I would be concerned about sludge buildup if you aren't really getting the engine up to operating temp for a sustained period of time. All oils do it, synthetic or conventional but synthetic seems to degrade worse in subpar conditions from what I've seen. Be well and make sure to keep your oil changes often and frequent...oil is cheap-ish while engines and repair bills are anything but🤙
I don't think "friction" as he tests it here really is how the engine sees friction. One thing he hasn't tested is "pumpability" when cold or hot. Probably way exceeds his method of testing for friction.
I could be wrong but I believe he has created a "backyard" version of the actual tests conducted industry wide🤷
With that said, the ability to pump the goo around at various viscosity levels is planned out heavily by manufacturers...unless you have minus 50°c for a month and freeze your coolant all should be fine under your hood👍

After watching this video and forums....
My first oil change is coming up at 1500 and want to give it a head start on engine life by doing an early first change. And I live in Florida so it's rarely frigid here maybe a couple months of below 45* nights
@@wailingalenPersonally, my opinion on a new vehicle is to stay with the oil viscosity recommended by the manufacturer and what is says in the owner manual. Sometimes manufacturers will list more than 1 viscosity based on temps and usage, but usually it is just 1. If you use an oil that is not recommended and you end up with an engine problem under warranty, the dealer will void the warranty. And unfortunately today, manufacturers have more problems with new engines than you would think. Maybe you don't want to wait until the warranty is over, but it may be good to wait for a year or 2 and/or 15,000 miles or so... just to make sure. Also, if you can I would stay with the winter grade and only increase the grade for the hot weather viscosity. In other words, if it says 0W-20, think about 0W-30, or instead of 5W-20, go with 5W-30. You just don't want a high viscosity when you first start the car and before it is warmed up... I'm glad you are changing the oil at 1500 miles. Manufacturers say it is not necessary any longer, but I do that as well... Change the oil often and use a good filter; change fluids every 3 - 5 years or so; keep the air filter fresh; use fuel system cleaner (i like Chevron Techron); and drive it right... and it will last a very long time. I still drive a 22 year old Acura that runs like new with 238k miles on it..
Its important to remember that some newer cars have very thin oil galleries. Its not just about wear its about getting the oil through the galleries. If your oil is too thick and can't get through the galleries properly it doesn't matter how much wear protection it has cause your car will be getting very little oil on key components. .
@@mm-jx7gf you might want to be prudent with the fuel system cleaner, it's been shown to drop lubricity in your engine oil whilst it's in the system.
We own a 2012 KIA Sorento, & a 2023 KIA Sportage. On the Sorento, I use 5W-30 in the cool months, & 10W-30 in the summer. On the Sportage, I use 5W-20 during the cool months, & 5W-30 during the summer months. BTW, we live at Puerto Rico, and summers get awfully hot.
Thanks for the feedback.
Awesome test as usual! I still believe the CAFE requirements have a lot to do with manufacturer selection. Obviously, I would want a "thinner oil" in a very cold climate during start-up.
However.... my 22-yr. old Buick calls for 10w-30 and I don't have any inclination to use anything else! Thanks for the tests!
I use 0w-40 even at -15°F, no problem whatsoever.
I use 15-40 in the summer and 5-30 in the winter, both full synthetic. 320,000 miles and not a tick from the lifters and it doesn’t burn a drop. Leaks a bit but not enough to get worked up about. I have to top it off maybe 1 or 2 times between changes and I do 10k plus changes. And top it off means IT’s just touching the low line and I like it at the maximum mark. More oil equals better cooling from it.
I have used conventional/semi-synthetic 10w-30 in every vehicle I've owned in the last 21 years and have never owned a vehicle that didn't last 400,000 miles or more. I have done this regardless of the manufacturers specification. All of these vehicles succumbed to rust or driver-induced failure...no engine failed because of my choice of oil. That said, I changed my oil religiously at 3k or 5k miles (3k for conventional and 5k for synthetic). I also DROVE my vehicles. I beat on them and/or I drove them for significant periods of time to evaporate the condensation in the oil.
Thanks and you are welcome! Thanks for sharing.
I used 5w30 in -30f and it worked fine. It started a little slow but I think that was more battery 0w30 felt about the same.
I agree it is all CAFE even 0w16 cars here recommend 0w20 to 10w30 in other countries. People try to say the engine was specifically engineered for oil that thin. If it was then the manufacturer wouldn't also recommend 10w30. Engine clearances have been the same for a long time. Tolerances have gotten smaller (less variation) and the finish is better but the actual clearances are about the same. Todd's new truck having half the oil pressure also supports this, same size holes thinner oil = lower pressure.
Companies care about profit and they lose money if they don't meet CAFE numbers. If thinner oil reduces total engine life but gets a better CAFE number of course they will do that.
Next year CAFE is 51 mpg cars, 36.6 mpg trucks and 45 mpg combined. For every 0.1mpg under those numbers they have to pay $5.5 per vehicle produced.
Miss the number by 1 mpg and you make 1.8 million cars (Toyota or Ford) thats $99 million dollars lost. Wonder why they are looking into 0w8 oil?
Longevity is not always or is never the primary goal.

The best automotive channel for me, straight to the point, no click bait, no gimmick, no weird music 😎
Thanks!
Great test. I never run a 20 weight in a turbo charged engine but that's where the manufacturers are going because of CAFE averages. I realize you have to tell people to follow the manufacturers recommendations because of the liability issue but they really don't care how long your engine lasts as long as it makes it past the warranty period. VW had a 7 year or 70 thousand mile warranty before they switched to 0W-20. Then they dropped the warranty to 4 years or 50 thousand miles. They wouldn't have done that unless they don’t have faith in the oil they're recommending.
Exactly what I was saying yesterday. Glad others are catching on the gimmick. Also don't trust the engine oil life indicator light. Just use full synthetic engine oil and change it at least twice a year even if you don't drive over the mileage limit.
Thanks! Thanks for the feedback.
VW has a 6/72K warranty for only 2018 and 2019 model years. They did it to help potential buyers feel good about the company again. Remember that they got caught cheating on their diesel emissions. They were fined and had to buy back cars from their customers (or provide other remedies). It had nothing to do with 0W20 motor oil.
If you look at the reason VW motors fail, it's not for lack of lubrication. Most times it's due to overheating. Their cooling system is overly complex and there are many places a coolant leak can occur. I've blown up two 2.0L VW motors in the past 4 years. Coolant leaks and runs low, then the motor overheats. Of course not temp gauge, so by the time the dummy light comes on, the motor is cooked!
Eurocars need a 30 or 40 weight period.
Their engines are not build for thinner oils.
@@alouisschafer7212 5W40 synthetic is recommended on most newer European cars, or at least it was.
Thanks for a great video! My 2002 5.3 Silverado has 358,000 miles, 5w-30 year round, non synthetic oil, and never had engine apart.
Wow. How often do you change the oil and are you in a cold climate?
You are welcome! Thanks for sharing.
@kanyeeastlolz Yes, Minnesota actually. All my vehicles.. every 3300 miles. So 10k miles, change it 3 times. Then, every 10k,
rotate tires and drain trans oil (trans pan drain plug 4 quarts come out). It is sooo cheap to do this. I'm 65, retired, my dad taught me this since high school. I have always used Castrol gtx non synthetic. Just my .02 sharing.
@@ronlind1757 Conventional oils do fine at 3k mile oil changes, but, Supertech full synthetic is $18 for 5 qts, and you can easily go 5k OCIs. It's also a superior oil, I don't waste my time with anything not full synthetic.
@@lonniebeal6032 You are welcome! Thanks for sharing.
The most important part of the video was at the end differ to the OEM recommendation on oil viscosity. Don’t just throw a 0w16 at your engine if it calls for a 10w40.
If you live in a hotter climate use the higher viscosity of oil recommended if it’s colder vice versa.
The only thing you should probably take into question is the oil change intervals especially with forced induction engines.
Thanks for the feedback.
You can not appreciate this mans attention to detail enough until you've seen hundreds of videos trying to be scientific but failing miserably. No 'whats', 'ifs' and 'whens' were left behind.

When you do oil tests it might be interesting to include the all-time best and worst performers on the charts at the end of each test (maybe give them a faded out color to set them apart). This would give some overall context to the small selection being tested.
Thanks for the suggestion.
@@ProjectFarm I'll +1 this one, sometimes I would love to know what the all time best in category is so I can go buy the best.
Toyota is now using 0W8 in the new hybrid engines, BMW is also using 0W12 is some of their new ones too. Crazy! Even more important to keep the oil fresh in those engines!
Thank you for sharing!
can't wait for 0W0!
If they are designed for it, it should be no problem. Bigger bearing surfaces and smaller clearances.
Just pour water in the crank case at that point.
Thanks for sharing.
Thanks!
Thanks for supporting the channel! I really appreciate it!
Additives make a huge difference on wear. It would be interesting to also do a test with bearing material instead of, or in addition to, the test wheel & pin you are using. I'm pretty sure that is what oil companies tailor there additives to.
Thanks for the suggestion.
I'd also like to see it be done under pressure somehow, since this is how the engines runs.
These pins are often made from a standard ball bearing steel. 100Cr6 or 52100 I think is the yankee name. ;)
@@jackmclane1826 yes, but that’s not what rod and cam bearings are made of.
Valve lifters/tappets,cam lobes,piston rings/upper cylinder walls,also timing chain links/rollers. Ball pivots used under rocker arms and pushrod tips.
Some cam drive chains and sprockets may be larger/better than the minimum practice,also some modern engines use "roller lifters" to try to reduce demands on lubrication but then there is the axle that the roller rolls on !
The oils are constrained by the fact that the EPA does not like a lot of antiwear additive(s) because of the idea that if the engine is burning a bit more oil than desirable the additive might poison the catalytic converter. I believe EPA has even found a way to spread that to Diesel engine oil requirements. So that obsolete SG rated oil from a few years ago may have had better antiwear performance under adverse conditions than today's oils although such standards as "GF-6" or "GF-6A" are an attempt to come up with oil that will offer adequate protection even with the EPA not allowing much of traditional antiwear additive.
I believe the super long oil change distances being advertised by the car makers today are pushing the oil far beyond what is safe. I believe that the additives wear out. A broken in engine is easier to lubricate in my opinion than a brand new one.
ideally the connecting rod and crankshaft main bearings are "floated" in oil most of the time that the engine is running.
What I’ve always found interesting is how manufactures recommend different weight oils for identical vehicles with identical engines in different markets.
For example my SVT Focus is recommended 5w-20 in the USA but 5w-30 in Europe. My Mazda Skyactiv-G 2-5l NA is recommended 0w-20 in USA and Canada, and 0w-16 in Japan, which has almost identical climate swings to the continental USA, and interestingly, 5w-20 in Mexico, which presumably doesn’t even need Winter-certified oil, or thin starting weight for that matter.
Seemingly same oils in different markets can have totally different compositions, might be a factor?
@@Broeils wow, never actually thought about that but you’re probably right. Good chance the regulatory bodies in different countries have different standards.
@@emotionz3 there's also different emissions regulations in different areas, and oil choice can impact emissions testing, and they probably have to test with the recommended oil.
@@emotionz3 No, the oils sold have the same composition - if they are meeting the same standards. And since they are shipped World Wide - such and such Penzoil Platinum Full Synthetic - 5w-30 will have exactly the same spec's anywhere.
@@daves7775 Many manufacturers order their oils in local refineries. Unless they control every batch, you do not really know if the oil meets the original specs. Only few companies produce their oils 100% by themselves and ship it worldwide
Another great video. I'm old school and always thought a thicker oil was the way to go but I'm changing my thoughts a bit on the matter. I was always a 15w 40 guy in everything even small engines. I've never had an engine fail using it but sometimes colder starts were a problem. Then the 5w 40 diesel oils came out and I slowly switched everything to that. Boy did it make a difference in everything especially the diesels. I've come to the opinion that unless the engine is under maximum load and at high temperature all the time the thicker oils may not be necessary. Also oil pressure is an indicator of resistance to flow. So low oil pressure doesn't necessarily mean the engine is not getting oil. Engineering is constantly trying to improve fuel economy and I think that is a major factor, but also I think modern engines using thinner oils have a much higher oil pump volume to try to keep things cool. It's hard for an older guy to get his head wrapped around a 1.5 4 cylinder stock engine producing 250+ hp. Most all auto engines have oil coolers today and that says something. More power in a small package turning higher rpms and a turbo or 2 make a lot of heat and thinner oils flowing faster pick up more heat and carry it away for cooling . Sorry long winded but I'm always trying to learn and understand
I think you will find most modern engines employ a coolant to oil heat exchanger, not just an oil cooler.
newer engines usually have a cylinder that's purposely designed to be micro porous, it means they actually hold onto thinner oils but struggle with thicker ones, couple this with reduced friction piston rings, tighter journals , oil passageways and bore sprayers designed specifically for thinner oils to flow through them it makes it a bad idea to put thicker oils in them. Even though the thicker oil itself is technically a better lubricator when put in a modern engine it actually lubricates worse and can potentially even cause issues.
Another thing to note is that a lot of new economy engines are direct injection which usually results in more carbon build up around the valves over time so using a thicker oil with less additives could increase the amount of carbon build up over time.
@@axeami1354 this all makes sense but then Toyota will specify 5w-20 in Europe and 0w-16 in the US for the same engine. If everything else were equal wouldn’t it make sense to equalize the oil specifications? Others reflexively scream CAFE but I’m not so sure
You grasped a lot of things most struggle with, a lighter oil doesn't necessarily mean less protection, because oil flow plays a lot into it.
@@tjm3900 exactly, it warms the oil in cooler weather. Also aids in bringing engine up to stable temperature. I was going to mention it but I figured I was a little long winded as it was
Yes! I requested this topic. Thanks so much for testing this.
Very interesting! As an old timer it's hard for me to wrap my head around the idea that you should use the same 0w-20 motor oil whether you live on a permanent glacier where anything above freezing is considered a heatwave, or, like myself, you live in desert where you put on a sweater when temps drop below 80. I'm going to need more than just a manufacturer recommending that, because as an ex dealer tech I've seen manufacturers recommend some pretty stupid things over the years. Things that are designed to make them money, not extend the life of the vehicle. And before y'all start typing, remember that oil temp and coolant temps are NOT the same thing.
Id say in the end it comes down to the actual oil temp.
The higher they climb = the thinner the oil gets its as simple as that
If you open your owners manual it will have alternate oils than what's on the cap.
My 18 f150 says 5w30 on the cap, but in the manual 5w40 is still in the temperature range... (although 5w30 would be better for me in winter).
If you run a block heater 24/7 then your engine never cools down and your oil doesn't break down the viscosity
I can get 10,000 miles between oil changes if I use a block heater
@@thecloneguyz running a block heater 24/7 is absolutely insane.

Mine calls for 10w30 but I use 10w40. Completely agree with you.
@@Gobbbbb At 10w-30 you are already at the upper end of viscosity. Completely unnecessary to switch to 40.
@@moshet842 With an air cooled engine in 25c+ weather, I'll stick to using the higher viscosity. There may be not much of a difference, but the 10w40 oils here in the UK are considerably cheaper and have slight better protection. It's a no brainer.

Greetings from Germany :)
Lighter weight oils are only used to squeak out some slight efficiency gains. They just don't provide as much protection to the engine components as the traditional 5w-30 oil (as the bearing test clearly showed) and thinner oils will sneak past seals and cause the engine to start burning oil and piddle on your driveway a lot quicker than 5w-30. If you ask the EPA; apparently burning oil and nuking an engine prematurely is fine and dandy as long as you can save 1/2 mpg in the process.
yes, i still use 10w40 oil and it is maybe most used here in finland, 5w40 is better for daily use in winter time but... i saw how it turns in 2 years without oil change.. it was like water lol :D
Most wear is at startup.
@@nwastormchaser9624 yes, fepending how cokd id it
Yea now imagine a 0-20 in a diesel engine,, the gm 2.8
When you have a chance, watch a video on the new Toyota 2.5L motor that I think was the first to use 0W16. They have been using this oil in Japan for a while before it came to the US. With Toyota's tight tolerances and low friction motor, I believe 0W16 has more than enough viscosity for their motor. If it didn't, you'd see quite a bit of metal in the oil and oil filter, which isn't the case.
I never heard of 0W-16 oil before this video. But these tests and this whole channel are amazing.
Well new yaris used 0w-8, you are just behind the times a bit.
As shown on the bearing test the 5W-30 had the least amount of wear. Protect your engine.
The only reason the 5W-20,0w-20 and 0W-16 exist is due to the EPA push for higher mpg standards.
I had relatives working at auto factories that saw the EPA reports mandating it.
I was wondering about that. My 2014 Toyota Prado lists a range of oils to use given the max/min temperature, and you can basically use anything when in the range of 0-40 deg. c
I believe hybrid vehicles especially plug in hybrids require thinner oil. Since the engine is not always running, thinner oil flows better at lower temp
I have a question though. Does engine wear happen mostly when cold starting? And if it is so, what kind of tests would reflect the effects of viscosity on engine wear?
An idea comes to mind, start/stopping the wheel 100 times without pre-oiling them. Would that be more reflective of real world circumstances?
It only makes sense that a thinner oil will provide less protection from wear. I always used 10W30 (I'm 81 and pretty set in my ways), but I have never had car that called for these thin oils. My vehicle is a 1995 Jeep Grand Cherokee with the straight 6 cylinders. It has 240,000 miles on it and I have only used 10W30 in it, which is getting harder to find.
EPA doesnt give a damn about your engine, if you need to buy a new one is more money (and taxes) for the government
My understanding is that most of the wear occurs on a dry start up, before the oil arrives to the overhead valve train. That's why the friction tester wheel is coated with oil prior to testing. Wouldn't the much faster cold flow of the 0W-16 more than compensate for the decreased wet protection? Especially in vehicles driven short distances?
There's a large factor that never gets discussed, and that is thermal expansion. An engines machined clearances are tested and engineered to be correct --- at full temp. The bearing clearances are effectively incorrect at cooler temps, and accounts for much of start up wear.
I use it Lucas syn on all oil changes, 185300miles going strong, one bottle per change.
Heavier oils will leave more of a film behind than water, oops, 0w16 does...
@lonniebeal6032 facts. I use 90w120 on my motorcycle chain. Going 100mph there is still oil on the chain.

Dear Project Farm,
Thank you for the informative videos that have real world application.
If I may suggest the following:
1. Calculate the weight loss due to evaporation as a percentage of the total initial weight.
2. Weigh the pins before and after and calculate percentage lost due to wear.
I look forward to many new videos.
You are welcome! Thanks for the constructive feedback.
The MAIN thing is to have all the oil you need in the engine. It helps if it's clean.
after that it's just a fine point on a sharp pencil.
I drive older stuff, with plenty of clearances, and the runny numbers "evaporate" most quickly from the crankcase, plus it rarely gets super cold down here. Good video.
My older vehicles definitely run thicker oils, However even my high mileage newer vehicles use factory spec. So many newer engines have such small oil passages that thicker oils restrict flow and cause starvation. Sucks because other parts with wear clearances could sure use the thicker stuff.
Old car with 0W will burn the oil, it will blow by the rings.
Thank you for sharing!
I'd love to see a video about the advantages and disadvantages of running very thick oils like 15w50 for extreme duty
Disadvantages would be fuel economy and flow issues in colder weather
Thanks for the suggestion.
I run 20w 50 in my hotrod and in the high performance engine in my boat. Both are only used in summer months. I use 10w 30 in my other two Mustangs.
I tried 20W50 in an old '79 Plymouth Horizon I had. The engine needed a valve job and was burning oil. One day the temp dropped and the starter could barely turn the engine over.
@@gadgethunter5732 thats what happened when I had it in my old BMW during the winter
Can you test, say, 10w-40 for lubricity and puring viscosity, example @ 30 degrees Celsius , and then test the 5w-20 @ 10 degrees Celsius also for lubricity and pouring to see if acts the same as the 10w-40 @ this temperature , or @ what temperature will be the same
Thanks for the suggestion.
When we first got a carton of 0W-16 oil at my shop, I didn't think it was for a normal daily driven vehicle. I though it was some specialty performance oil for a 2 stroke or something. Just goes to show how much closer the tolerances are in these newer engines. I drive 20+ year old Japanese vehicles and run 10-W30 in them with no issues. It helps that it rarely gets below freezing here.
always hear that term "new tight tolerance engines". but in reality pretty much all tolerances have been the same since the 90s as far as japanese engines go. also the reason the idle oil pressure on his 2020 is so low at idle. same bearing tolerances but lower viscosity oil.

Started using a synthetic 5W-30 in the mid 1980's. My dad said I was crazy to put such a thin oil in my car! After about 200,000 miles I gave him the car and he drove it for years.
What car was that🤔?
Thanks for sharng.
5W-30 is very thin for a 1980s car. Most 1980s classics want 10W-40 oil.
As you said in the very end, use what the manufacturer calls for. Bearing clearances are getting tighter than ever and if you use a 5w-30 or higher in something designed for 0w-20 or 0w-16, you might not be getting good oil flow to each area of friction, and the same can be said if you use thinner oil when it should be thicker. Extreme climates might change what you want to use though.
But most of your wear will be a result of choosing to go way too long without changing your oil, especially on engines notorious for burning it. 5,000 miles max since modern engines use oil to do so much more than just lubricate the crankshaft and camshafts.
I feel like I started a war here. The oil consumption is generally from low tension piston rings, but some engines are notorious for this being a severe problem where others it's just a meh issue. There are additives out there that go in prior to changing the oil to "dissolve" hardened oil deposits that cause those rings to stick. Just change your oil regularly and learn to check it yourself so you know if you're low or not, your favorite in and out quicklube is just going to drain and refill, they dont check for that stuff.
@@bywonline Who said you can't run 30 in a track car?
I'd tend to agree. Originally I discovered that Ford specified 0W20 to assist in passing EPA fuel economy tests, so I then began using 10W30 in vehicles that were spec'ed at 0W20 with zero issues. This was a deliberate decision on my part after significant research to guard against excessive wear. Fast forward a couple decades, and I tried the same thing in a 3.5l Honda Odyssey...BIG mistake. The bottom end on the Honda 3.5 would take the thicker viscosity just fine, but the oil passages in those VTEC heads certainly couldn't, and complained with a significant amount of clatter on cold starts. I'm trying to get the thicker oil flushed out but 2 changes later the valvetrain still clatters a bit on cold starts.
Good Point!
So for your next car people find a car with an engine that is port/direct injection as well as something that uses 5w30 oil so it does not wear as much
Remember y’all, some parts of the world don’t even have 0W20 for the same engines! If you look at oil charts for various makes and models you’ll see it everywhere from 0W20 here in North America to a 50wt in the Middle East. The “ideal” viscosity for protection and cold and hot flow is 5W30 (North America). Ford never changed their engine designs in the early 2000’s. The CAFE dictated and oil companies sold to them and they retested their engines on 5W20. The same reason why BMW M engines had rod bearing failures running 10W60 🙈. It’s not “clearances” that matter what matters is protection. 5W30 is already pretty thin…
It would be interesting to see a comparison between some of the newer "Hybrid Engine Oils" (Mobil1, Valvoline) compared against their "Regular" variants. Maybe add some tests with impurities/fuel dilution to see how they hold up? Always love your content!
Thanks! Thanks for the suggestion.
@@ProjectFarm Could you test silicone "oil" in place of crank case oil?
@aboy467 I'd like to see this as well.
It all depends on bearing tolerances in the engine of which you're using the oil . Always use the oil viscosity that the manufacturer recommends . If you have something rebuilt and the crank bearing tolerances have changed then you use a slightly thicker oil . My .0010 under bearings made the viscosity change from 5W30 to 10W30 in one of my engines . The oil has to be thick enough to be able to form a proper hydrodynamic wedge between the bearing and it's cap yet thin enough to flow easily and quickly .
Thanks for the feedback.
Both of those have the same range of viscosity at operating temperature.
A two stroke oil shoot-out like synthetic vs conventional vs caster bean oil would be awesome to see!
Make sure the 'gum up' factor is included. Castor oils gum up power valves badly.
Thanks for the suggestion.
It may start on fire. Somebody on TH-cam tried olive oil and that happened.🔥
@@joewalla8438 all of those are in use now and have been for a long time.
The smoke factor should be measured in more than one way. Two smoke FTW!
It would probably be very difficult to do, but being able to test wear resistance while the oil is very hot would be cool. Them being at room temperature is closer to winter viscosity than hot viscosity. I wonder if they would be closer at those higher temps.
Thanks for the feedback.
I'm just glad you specified to stick to the recommended oil per car as my dad failed to do that in one of my first truck and ended up clogging up my oil pump and the pumps intake screen because the oil was to thick and started sludging up within a 3000 mile range
Thanks for sharing.
What were the grades?
We dont use all this thin oils in eu all cars i own use 0-30 or 5-40 + there is no point using to thin oil if u dont live in extreme cold climate. Now days summers are so hot so 5-40 is better for protection
I think it would be a good video to test all 4 oils in your truck. Run 1000 to 3000 miles then do a oil sample test after each oil! Thanks for all your hard work!
You are welcome! Thanks for the suggestion.
caballeroloco............why don't you try it in your truck, anybody can get oil samples done.
I sent my Italian Iveco 6 cylinder Turbo charged diesel engine using Ams Oil 15-40W diesel with a by pass oil filter system that was like 2or3 microns. I sent my oil sample in at 15,000 miles it came back with a clean bill of health, I the tried the same oil at 25,000 miles and it was still OK? The trick was I changed the engine twin oil filters at about 7,500 miles and I kept the 3 or 4" diameter by about 12" inches Ams by pass oil filter till only one half of the filter was still hot and the other half much cooler? An engineer taught me that trick as that large oil filer was very expensive my engine went 350,000 miles when I parked it 20 years later as finding parts were very hard to get in the United States. I find it Odd the the same engine and Turbo charger was still good when I parked the truck?
Yes, because the test will show more results on where and tare. What components are worse. The 30w wate should be better for where. 16w whatever seems to thin depending on how hard you run your vehicle's.
@@77.88. I do the same on my Chevy cruze. It maybe where'd but it beats changing my oil like a idiot every 3,000 miles. I only do it once a year. It's the best feeling ever. Lots of pride saying so too. I run amsoil signature series 0w20
Most, if not all, new Toyotas require 0W-16, I'd never seen that oil weight before getting a '19 Camry. They're pretty strict, too - if you don't have 0W-16, you can use 0W-20, but must return to 0W-16 at the next oil change. Unfortunately, at least around where I am, only the dealer has 0W-16 available. Seeing how free-flowing the 0W-16 is, I can understand why it's recommended for use - Canadian winters can be cold!
CTC sells Mobil 1 0w16 fyi
Thanks for sharing.
Allot of the hybrids use it and I can see why when the engine is stopping and starting the oil need to arrive quickly.
in the mediterranean, even official toyota dealers use 5w-30. 0w-whatever can be brought in at a special order and a ridiculous price.
I have used 10W30 motor oil in all my older trucks and have never had any issues !! Nice job !!
Generally speaking, if you stick to the oil weight specified by the vehicle manufacturer and change it regularly, you won't have any issues.
Thanks! Thanks for sharing.
I have used it in all my lawn mowers. All my vehicles, I've never had an issue.
Did that older truck have low tension piston rings, or GDI? If it's older than say the 90s, they didn't. So these newer cars will need that crap 0w20 in the winter, and it's probably safe to use 10w30 in the summer, I do...
@@lonniebeal6032 94 chevy !!
The best as always! Didn't waste a second neither. It is hard to watch other YT that take 2-3 minutes to get started!
Thanks!
I think you said it best at the end. Your recommendation is to use the oil the manufacturer recommends.
I'm old school and my car calls for 0-16 oil. It's hard for me to do, but I do.
Thanks for the feedback.
I agree. Old school here too and have a new Toyota and forced to use 0W-16 due to warranty. But other countries can use 5W-30
Yeah mine calls for 0-20 and I get reminded every time when Inlook at the fill cap 😳
In extreme cold the oil getting there quickly is far more important than anything else.
I think a different low temp test should be added to represent the situation most people are in during winter, such as zero degrees F.
@@bills6093Did you watch the video?
@@Dr-TH-cam Yes, his freezer is at -40F, a test which doesn't mean much to most of us.
But an engine block heater makes that a moot point as the oil won't be -40. Also it should still be coated from the last time it ran, unlike in the test where it gets cleaned between uses.
@@Dr-TH-camwhat hes saying is also test the cold oil from 0°F not just warm new and -40 because a majority of people arent going to see -40 temps where they live
Blows my mind that all hybrid powertrains recommend 0w20 - 0w16 for the engine side assist. Looks like ill be blending some 5w into mine. Thank you for getting right to the point with tangible results and sharing it with everyone. ❤
You are welcome!
Not just for efficiency, hybrids especially plug in require thinner oil. Imagine this, you’re stuck in traffic for a while and only using electric power. Once the traffic is clear and you put your foot down, the cold engine kicks in for power. But the thick oil doesn’t flow quite easily as the thin oil does when cold, you end up damaging the engine even more
@@Dankboi420 if you love in the cold sure everywhere south of the mason Dixon line here in the states is usually above 30 degrees after spring they never go below 80 in Texas until winter
I have done a small amount of research on oil weight and have come to the conclusion that a lot of manufacturers will use thinner oils in the same engines just for the fact that the EPA wants tighter fuel economy numbers. My current vehicle which has the same engine in Europe and South America uses 0-20 here and 5-30 everywhere else. I believe that even tho thinner oil causes more wear as you have also proven it is a trade off for fuel economy. I have currently switched to 5w30 which the owners manual does say is acceptable for towing and extreme usage. Even tho the cap says different the manual does say thicker oil “can” be used and is acceptable as it is used in other countries as well!
Thanks for the great video!
You are welcome! Thanks for sharing.
What car have you got?
@@notsureyouhemi and also a 3.6 pentastar
You recommend 5w-30 on a 3.6 pentastar? I live in AZ. My Jeep is recommended for 0W-20
@@swimers100i run 5w20 in the pentastar. As we see in these videos 5w20 shows significantly less wear! Also no lifter chatter at start up even at -10 degrees. I run 5w30 in the hemi
After Brian at FordTechMakuLoco recommended full synthetic 5w30 (he likes the penzoil platinum full synthetic) for my F150 with a 5.4L 3V engine, I definitely switched over from the factory-recommended 5w20 blend. He likes the heavier oil because it sticks to the rockers and other parts in the top of the engine.
Thanks for sharing.
Thats why i switched in my jeep wrangler with the 3.6l pentastar, they are known to have some oil filter housing and rocker arm issues. I think the heavier oil will help out! They magically switched in 2013 to the 5w20.... probably for fucking CAFE gas mileage bullshit
Your government at work.
Ford recommends 5w30 for the same 3 valve engines in the rest of the world and they don't have the same problems with the valve train failing.
This is a great channel! As someone who builds race engines for a living I would strongly suggest staying with the recommended oil viscosity. The clearences in modern engines are very tight compared to 10years ago. Going from 0W16 to 5W30 can cause accelerated wear on bearings, piston to wall issues and piston rings.
Great test, keep them coming please.
Yes, this test doesn't seem to test differences in tolerances.
The lighter oil viscosity is also for the variable valve timing in modern engines
@@edbaczewski2959 I love how people are always looking for any reason why low viscosity oil is better. The truth is that it is not because viscosity is always closely related to lubricating properties.
In the eighties, the standard was 15w40, in the nineties, 10W40, etc. And everything worked great, including the variable valve timing, which was recently 50 years old, even though the world only knows it from the end of the 80s. Since then, every car manufacturer has named it after themselves, for example Vanos from BMW.
.
Do you manufacture racing engines for 0W16 or 5W30 viscosity oil?
@@MijanboyStraight 0 weight is used for qualifying in racing .
Always a great video, love the breakdowns and simplicity for anyone to understand. keep up the amazing work man, thank you for another great video
Appreciate it!
Other TH-camrs should take notes and learn from this man, this is how videos should be made. Just get to the point! I love it!
Thanks so much!
Hey Todd, have you thought about doing the bearing test AFTER freezing the oil? It would be interesting to see how each oil performs on a bearing when frozen.
I've wondered that. The thing is, once you actually get to the testing part, the oil has warmed up. You've got a good idea, but it might be difficult to test.
Thanks for the video idea.
5 gallon bucket and some dry ice could help keep the oil cold while set up takes place.
@@TheCAD66
That's a good idea!
@@TheCAD66
Just put the oil directly into the test cup and freeze it. Go from the freezer to the testing rig.
Miss the oil test videos. I know you can only test so much so many different ways but glad to see another classic from you Project Farm. Love the oil test videos 😂❤
Thanks!
Always enjoy the oil tests! 👨🔬😎✌️

@@RRaucina Wayne & Simers, too!
Wow, that is not the result I was expecting. Very informative.
Thanks!
Thanks for all the effort you put in your videos, maybe you can include a 20W-50 and 15W-50 in a future video, here in Brazil 20W-50 is very common because of older cars and hot weather.
You are welcome! Thanks for the suggestion.
Same here in South Africa. I would also like to see how the oils in this video do at high temperature on the wear tester. To simulate using it in 30-40 centigrade.
Gulf countries do that too.
Awesome content as always. One word of caution though. The OEM oil pressure gauges on cars are not always accurate by design. Some operate like on/off switches and are there to just report any pressure. As an example miatas are notorious for this.
I'm pretty sure all fords trucks since the 80's are like this. Just an idiot gauge. Pretty easy to tell tho, they only ever read 0 or 60ish %.
Thanks! Thanks for the feedback.
I love all your videos it’s definitely helped me make some buying decisions in the past. Just a suggestion though I’d love to see you add the bearing test with the cold oils to the videos. Best way I could think to simulate starting your car in the cold of winter and letting it warm up before driving.
Thanks! Thanks for the suggestion.
The high wear rates in a real world engine when it is cold are likely due in part to the presence of condensed water and liquid fuel removing some of the oil film from engine wear areas. Especially the upper cylinder and piston rings. @@ProjectFarm
You are so thorough. I check for your reviews before I buy anything. Haven't steered me wrong yet.
Thanks!
Great video. Because VVT and oiling systems in vehicles are getting a lot more sensitive, it is important to use the oil the engine was designed for. Even if it seems too thin. I am a Toyota mechanic, a lot of the newer Toyotas are going to 0W-16. They started around 2018 with the Camry, and since then I’ve seen several get to 200,000 miles and they don’t burn a drop of oil.
I use the recommended 0w16 in my 2021 Corolla 6spd hatch. I use 80W90 GL4 (not recommended) for gearbox oil. I haven't had any issues. 75W seems like a waste of money if you change it out every 25k miles.
Avoid this guy at all costs!
Thanks! Thanks for the feedback.
the same engine in Australia has oil recommendation all the way up to 10w-30. It's in the manual, black and white.
I'm wondering if you could do your tests with the oil at operating temp and see if the results would be different. Love your content!👍
Thanks! Thanks for the suggestion.
Great idea!
Yes, please do an operating temp test. The oil behaves totally different vs room temp.
@@corruption1724 From listening to engine racing techs, they said you use a thicker oil because it becomes thinner as temps rise and act like a thinner oil. I would believe if you are just driving back and forth to work and store you wont have to worry too much tho.
- Indeed. Under normal driving conditions and of course with proper maintenance of the car, we should not worry too much about the oil if it matches the specs.
In my Beemer X5 3.0D = Shell Helix Ultra, it is equivalent to the Penz.
Furthermore, I only recommend XL Boosted from Amsoil, absolutely top quality, smoother engine, visco is maintained, temperature of the engine remains optimal. Etc. To buy!@@wanglee21
I love your videos there’s no beating around the bush always straight to the point. I rely on your testing before I buy anything. Thank you brother for the honesty 💪💪🇺🇸🇺🇸🇺🇸🇺🇸
Thanks and you are welcome!
Thanks for running these test. My 2010 Honda element calls for 5w20 but have only used it maybe twice since i bought it new. I use 5w30 in it and my 2004 Nissan Titan as i don't think the 5w20 provides enough protection when it gets to be 110 down here in Texas. Oil shears down so that means the 5w20 will be even thinner after a few thousand miles. We don't usually see below freezing temps here so i don't worry about that. I normally use the Pennzoil ultra platinum not burning any oil with over a 150k on the little Element. I don't wait for the maintenance minder to come on i change at 5k or sooner. Oil test may say it still good but they don't test how much dirt and soot is in it.
You are welcome!
I have been asking myself this question with all the 5W-30 oils that are recommended just to save the tiniest bit of fuel compared to the 5W-40 that I usually use, especially in older engines (I have a Benz and an F-Body from the 90s).
on new cars, the thin oil is really important. older cars, it's not such a big deal. apparently the new cars have thinner channels and avoiding all the technical jargon about how the oil is circulated and distributed, basically using a thicker oil in a 0w-15 recommended car is like using axle grease in a 10w-30 recommended motor. running dry for longer at every start, causing damage. it probably does save fuel, but it's not the only reason for the change over time. hope this helps out somehow.
@@SneakySolidSnake The point is that on older cars the protection layer might be too thin and such thin oils could also create leaks.
Now the 5w-30 is actually considered thick !
I believe that some of this spooky thin oil stuff is driven by car makers trying to avoid CAFE penalties,that would explain the different oil viscosity required in different countries in the same engine.
I think only with synthetic oil technology can even the 5w-30 oils and 0w-40 oils be made that won't fail miserably in use.
One thing to remember is that the same horrible technology that Cadillac used to call "V8-6-4" is back,it requires rapid flow of oil upon the command to pump up or collapse valve lifters and engines that have that may malfunction unless using spooky thin oil. Also known as "displacement on demand" or "cylinder deactivation" I think some cars from Honda,GM and Chrysler/Dodge are using it to meet CAFE
It‘s an awesome video as always.
For the car guys, keep in mind that modern cars are usually equipped with an oil-cooler that helps keeping the viscosity stable and the evaporation rate low. That results in different operating conditions between the low viskosity stuff and the multi-grade stuff.
Thank for sharing.
Oil cooler isn't gonna do much to the extreme temps the oil sees above the oil control ring. 0w-16 and 0w-20 is all epa bullshit so cars can get like 1 mpg better at the expense at blowing up right after the warranty expires.
@@dkis8730Good thing I have a lifetime power train warranty on my Camry 😁
Just for consideration, that late model Chevrolet showed in your video does not use an actual oil pressure gauge, but a “dummy” gauge which is programmed to stay at an approximate position as long as the pressure sensor sees X_psi minimum.
Yes, they are just an on & off switch mounted to the engine. The dash is an estimate based off of RPM.
@@duramax74 heck my Colorado does not have an oil pressure gauge at all, well it has one in the trip computer on the cluster but not a needle like my 1995 S-10 did.
