Here's the list of motor oils reviewed. More details in the video description. Thank you! Mobil Delvac: amzn.to/44Huvkm Rotella T6: amzn.to/3K7VmMI Royal Purple: amzn.to/44LrzTB Schaeffer’s: amzn.to/4bDNbn9 Hot Shot’s: amzn.to/4dJMKJS Amsoil: Available at the online Amsoil store
I have a challenge for you 12 car batterys how longbwould it take one simple altinator to charge them and would they last a full day running a heater blower motor from a house furnace and use voltage reducer like light dimmer to slow lower juice to fan
Nice comparison- one thing is the Mobil product was a synthetic blend product. To do an actual comparison against its competitors would be the delvac extreme,which I believe used to be Mobil 1 diesel. The Mobil extreme has upwards of 40% more additives and anti oxidation capabilities of the 1300.
Our whole semi fleet switched to amsoil and we've seen 30% less repairs with millions of miles tested. Use to run rotella like every shop but the results have been speaking for themselves. Great channel!
@hkfan4596 we send oil samples in ever 10k miles I can assure you it's the amsoil when we couldn't get it for a little bit during covid shortages we ran rotella and ever oil sample showed higher wear materials from bearings. The valvoline blue actually performed better than rotella. When we first switched we did half our fleet to see if cost difference was worth it in our trucks on rotella engines laster around 500 to 550k miles. Amsoil constantly hit 900k and above which is good for heavy haulers
AMSOIL. Yes its expensive but its the best. TIP: Become an AMSOIL member, it’s a low yearly fee. It gives you a massive discount on each oil purchase and rewards. You get money back fast, and save big in long run for best oil. I use it it in all my cars, trucks, and tractors so I save a lot of money.
I also don't have any diesel engines, yet I use heavy duty diesel engine oils in my petrol generator and my electric air compressor (also recommend multigrade 15w40 as mentioned in it's manual)
Not just diesel, I started putting diesel oil into my gas engines 20 years ago when they started taking zinc out of engine oils. It’s kept all my old flat tappet (pre 1988ish) engines alive.
@@ThirteenTwentyRepair Yeah. Years ago I did some general farm work. Rotella not only went into the semis and big tractors but also into atv’s, mowers, welders, generators.
The Shell Rotella T6 has been a common oil used in the motorcycle racing community for decades. Sportbikes (Except for some Ducati's) have a wet clutch. The transmission and engine are within the same cases and share the same oil. Motorcycle specific oil can be VERY expensive so some of us started using T6 around the year 2000. As your tests show, it contains 0 Molybdenum. Thats what makes it safe for a wet clutch. Racers also change the oil often. Usually every weekend if not more so the cost savings can be significant. My own experience is over 25,000 miles each on two Yamaha R1's with no engine, transmission, or clutch issues.
What year is your R1? I have a 99 that I run 15w 40 T4 in for the last 10 years or so and I love it. I don't know if it's all in my head but the transmission seems to like T4 better than T6 even though I want it to like the synthetic better. I tried Delvac 5w40 full synthetic 20 years ago and it hated it. 55K miles now on the original clutch so I love Rotella.
It's not in your head. Reviews show that many users find better shifting with the T4 over the T6. Either one is a great oil. What people don't know is Shell changed the formulation on the T4, Though not listed on the bottle it is now semi-synthetic and states it on their website.
To my knowledge, the product viscosities are approximate. For example, brand A may be thicker than brand B, but would still fall in the same viscosity rating range, such as 5w30, etc...
THE missing variable THE MOTOR! Lets using cooking oil and on bike bearing and expect results? This guy does not understand anything about cars. TO test oil it must BE IN A MOTOR!
Shell Rotella only in this household. Two Kenworths, three John Deere field tractors, two Kubota tractors, three diesel pickups. All run this oil for years with no problems. Change any oil when you should and there will be no problems. We always change before the recommended time interval.
Everything in my arsenal of vehicles and engines is running 5w40 t6. 140k miles of use in my supercharged civic, and so far 50k miles in my f150 with the 2.7. My lawn equipment gets t4.
I've always used Rotella on my 07 International 9400i with a Cat C15. Did my first rebuild at 1.4m miles. I'm just over 1.5m miles and never had an issue with the engine.
1:41 Thanks for emphasizing that -40 degrees does not need a descriptor, as it's where both Fahrenheit and Celsius scales converge. Another great video as always.
You are a true master of your craft . I can’t even think of someone coming in close for 2nd place. That’s across all your videos. Thank you for providing so much info in your videos and for all your time you put in.
I used to use rotella t4. My friend uses delvac. Neither of us has had any issues. We ran 12,000 mile intervals in our Detroits. No problem with either. Great video!
Schaeffer's did a customer testimony video of their oil. It was Urfer trucking company 30k oil change intervals on a 3406 cat engine. They broke the engine down at a million miles and it was spotless, still like new.
Rotella's price to performance ratio is why it's so common in fleet applications. It's not the best, but it keeps costs low in an environment with controlled service intervals. Consistent, regular oil changes are more beneficial than any additive package that exceeds OEM requirements!
in fleet operations you should totally be using amsoil or pennzoil ultra prem. Those vehicles are run HARD and seriously need that oil protection. Now if it's fleet as in car dealership sitting on the lot then obviously it's barely run at all and you can get away with anything
@@jason200912 Go work in a large corporate fleet management facility that oversees thousands of vehicles. Paying 3-4x as much at each oil change, versus the average vehicle lifespan and average repair costs over the life of the vehicle, there is absolutely no financial incentive to spend that much on oil. Factor in vehicle depreciation into this equation, and it makes even less sense. Any oil that meets manufacturer specifications is more than enough for fleet, even in a severe duty application. Oil analysis is common with large, internally-managed fleets, but only to either confirm current service intervals, or to determine if modification is required or financially beneficial.
Every video I watch from you on every Sunday at the end of the video I always tell myself "and today I got this much smarter" and it's true because you teach us so many things with bad products and good products with no bias remarks. The best TH-cam testing channel I ever watched so glad to watch every video you make❤
I packed Schaeffers aerosol products back in the 1980-1990's. The head chemist was Mike Ryterski. Guy was a genius. So many different products, all top notice and a hometown company. He always put the good stuff in his products. Their compressor oil dropped our rotary screw temp by 20'F. Most unusual product was a zinc bearing goo used on huge dredging machines. 1 can to a wheel. Offset wheel device would run on a rail track, pick the whole machine up and move it 8 to 10 feet. Extreme Pressure!
Schaeffers is king. I gave it a shot about 10 yrs ago on my concrete pump and it reduced my hydraulic fluid temps constantly 20+ degrees, same thing when I put it in my truck, i than got into it and started doing oil analysis, different tests, etc. schaeffers is king, with the addative moly in it, the longer u run Schaefer’s the more the molly coats everything and is a game changer when it comes to cold starts. When I went to Schaefer’s in my Allison trans it reduced my max temp i would typically see at the track where I’m really workin it, 25-30 degrees and I’m not exaggerating even a lil bit
I started out my working career as a diesel mechanic. My boss swore by shell rotella T before most of those others even existed. He showed me the difference on engine teardown. Shell engines were clean inside. The Delo engines had a thick sludge layer that had to be cleaned off. On cars it was the pennsoil that left the worst sludge behind.
I'm 61 years old, and since I was able to use all in all of our equipment it's been nothing but Rotella. I have rebuilt my John Deere dozer engine which had close to 9000 hours on it and it still looked good on the bottom end, not to mention all of our logging skidders they get the piss used out of them and never had any problems out of Rotella
I use Rotella in everything including my atvs,dirt bikes,Harley and Suki street bikes,pickups,zero turn,push mower,etc and I've never had any bearing,buildup or wear issues in any of them,nor in any of my big trucks throughout the decades... I swear by Rotella and won't use anything else anymore...
there is a lot that goes into great engine life. i use rotella t6 change it every 5 thousand miles, good quality oilt filter and keep the air filter changed regularly. the results have been great especially when considering i have save hundreds of dollars over the years one the price of oil.
Great oil review, I was running the 1540 Amsoil but I switched to the 5-40. It is way better at cold starts in my 6.0. Amsoil claims it has the same high temperature performance. It would be interesting to see cold run and hi temp wear between the 5-40,6X Amsoil versus 15-40,6X?! Merry Christmas!
I have been using Mobile Delvac for years and years. Never a problem. And I run T-6 in the winter when temps are going to be Sub-Zero. I learned that from your previous video, a few years ago.
I'm in norther Wisconsin. Further north than most canadians. -40° winters are normal. I have only ever run delvac. My oil analysis always comes back clean. My truck has 300k. I hardly ever plug in. Let it run in high idle for 10 minutes and I'm good. There's no reason to spend more money for the same results.
I used Delvac since I purchased my 97 7.3 power stroke. Back in 97. Change it around 4K . I've always been amazed at how clean the oil was even if I let it go 5k which is rare. Others 7.3 oil I've seen. We're black a tar. I've recently changed to mobil 1 extreme. It's a synthetic blend. Also started adding a 1/2 bottle of arch oil friction modifier. If you research oil for the 7.3. Ford actually doesn't recommend Delvac 1300 now. Stating in their testing it doesn't meet their 1,000 ppm specifications for phosphorus! I also read where Mobil changed the formulation of Delvac 1300 to meet the new CJ-4 SAE standards. No doubt this negatively affected the anti wear additives. Hopefully, all the miles that I put in my truck using Delvac. Was with the original formulation. However, this is my reason for changing . Boy !! Would I love to see the results of these test with the Arch oil AR9100 friction modifier added to them. That stuff gets amazing reviews. Mostly for injector stiction. Which I don't think I've ever had. It still looks like a winner of a product
Do I own a diesel? Nope. Do I plan on owning one? Nope. Did I watch the whole video? Yep. All your videos are so well done and very informative! Thanks for your work.
My 2011 BMW diesel M57 is the most efficient motor I own next to my Honda B-series. I make over 300 HP and 487 torque. I’ve driven 392 miles and still have half a tank of gas leftover. I have had no major problems since ownership to this day. Knock on wood. I was at one point also deterred by diesels before owning one
Been using rotella t6 in all of my diesel trucks. 02 f350 7.3l powerstroke zf6. 246k miles. 03 ram 2500 5.9l cummins 48re 242k miles 05 f650 6.0l Eaton Fuller 5 speed. 96k miles. 07.5 ram 3500 DRW 6.7l cummins g56. 143k miles 08 f750 6.7l cummins Alison auto. 104k miles. All of them (even the 6.0) are on the original block, zero blow by, healthy compression, and have never been rebuilt. I own a tree service, so they get worked hard daily hauling wood, machinery, chips etc. Sure, other oils may be better in certain categories, but for the price, in my opinion it can't be beat. I used to have a 93 ram w350 dually on a 5 speed. I bought it with 380k on the clock. I knew the original owner. He told me he only used t6, so I kept with it. Over the next 10 years it earned another 300k miles. I sold it just shy of 700k on it. Original rings, pistons and block. It had a different head. But I was pleased to see that it needed no cylinder work when I pulled the head to replace it. T6 has proven itself to me. I'll probably never use anything different. Especially when the better performers are 2x more expensive. I do use the hot shots secret diamond g56 oil in my 07.5 6 speed ram dually. Fantastic stuff. Excellent review and video as always, Todd. Thank you for all you do.
The very Best TH-cam testing channel that’s unbiased and very informative. Thank you for saving me thousands of dollars buying inferior products from a very loyal subscriber.
Would be nice to see you test multimeters, checking voltage, amperage, and resistance accuracy, seeing if the cheap $50 multimeters are as good as the more expensive ones
I've got two meters I built in highschool, one analog and a digital. 40 years later, they both still work like new, they don't look as good, I still use them today.
Canadian here. The cold flow with the Hot Shots was WILD! Thats a game changer for winter diesel starts, especially in Powerstrokes with HEUI injectors that need oil pressure to start.
I didn’t know we could super chat when not live. But I think you should do live streams man, us mere indecisive consumers would love it, even if it’s just BSing with us on live chat, or simple easy comparisons you could do in real time. You’d make a ton on super chats for sure. I have consulted your videos on so many things, and I still find old videos about things I use everyday that I hadn’t seen yet…
TODD YOU HEARD AND ANSWERED MY PRAYERS!!!!!!! No seriously thank you so much man you are my FAVORITE youtuber by far and I look forward to your videos every Sunday!! Ive been requesting this one for years it feels like! I am so excited. Thank you @Project Farm
Thanks Project Farm for such a great video once again. This confirmed my choice of Schaeffer's for my 7.3L. Been using it for 4 years with great results!
Are you saying schaffers is good for that many miles? I have 6.7 ran achaffers in. Truck loved it. I just atarted using Presidential 5w40. Made in Ohio. My truck likes that to. 120$ for 5 gallons. Prety sweet deal. @ElitheBeeGuy
@mc-nk3zu I run 15w40 fully synth with shaeffers and yes it's good for that many miles although I would change oil sooner....better cleaner oil will prolong your engine life more then anything out there. I personally did 100k miles on one oil change haha don't recommend anyone try as this a 7.3l basically a tractor
@@salman13 Liquimoly is a German brand oil made in Germany. These are all US oil brands made in the US. He's testing domestic brands that are readily available on shelf. While I have seen Liquimoly additive sold in parts stores none of them sell the oil.
I've asked you to test motor oils for air cooled V-Twin motorcycle engines, for a couple of years now. I ask because no-one has done it, to my knowledge. You'd be the first, truly independent test, ever done. You have no idea how highly debated this subject is in the Harley community. PLEASE test these. Especially Amsoil V-Twin 20w-50, Mobil 1 V-twin 20w-50, Royal Purple, Screaming Eagle, Redline and anything else you can think of. I promise you, this would be a hit! Thank you for doing these tests. I do base a lot of my purchases on your recommendations.
This vlog is perfect timing, we are going for more regular oil changes, some of our engines are stated 10 k /15 k oil changes, so we are looking at oil and filters at 6k using cheaper oil, the recommended oil are near £80/100 gallon, this vlog has made our minds up to use several of the oils on your test vlog, thanks for you efforts to bring such useful knowledge,👍👏👏👏👏👏👏
I run T6 in all my ram 2500's and have had great results. 3 trucks with over 700k miles and still going strong! I do ad 1 quart of Marvel and 1 quart of Lucas each oil change though.... Maybe I will try Amsoil to see what happens now. Thanks for everything you do!!!! So much unbiased info and entertaining to watch!!
@Avies48 The Lucas helps with longevity of the oil, and the MMO I swear makes the oil temp a couple degrees cooler. My trucks tow from 3k lbs to 16k lbs constantly, and still run perfect!
I love how your videos are thorough, objective, and fair for each test you do! Thank you for your contributions to this platform and to all of your everyday views.
Someone mentioned your channel on another video, so I decided to come take a look... This is exactly the type of content my ADHD/Autism needed. You have a new subscriber!
Thank you for this video, I was hoping you would do a comparison like this years ago! I had a 2018 RAM 5500, and put about 365,000 miles on it before I switched to a 2022 Kenworth. I tried the Shell Rotella T6, Schaeffers, Amsoil 6x Signature, and the Hot Shot Secret Blue Diamond oils. I send an oil sample to Blackstone every oil change. The Hot Shot Secret performs the best out of the oils I have tried in your test comparison. I figured all of this out with the RAM, I broke in the Kenworth with the Shell Rotella T6, while doing short oil change intervals during the first few thousand miles. Then I switched over to Hot Shot Secret after about 15,000 miles. Hot Shot Secret isn’t cheap, but the data from Blackstone shows it performs the best overall. Since my livelihood depends on my truck, I only want the best oil in my truck! I’m not surprised that Hot Shot Secret flows the best in cold temperatures, as both the RAM and Kenworth start right up and run smooth in below zero temperatures using that oil! Thank you again for this comparison, so many people will find this information very valuable!!!
@rowmacg I use hot shots as well could believe the difference when I made the switch . Only oil I use now in had my 2019 Mack Anthem go 500,000.miles no engine issues at all before I got the new truck and I unload with a PTO. But don’t remember my engine hours .2023 Mack MP7 Anthem .2011 GMC 5.3 1500 and wife’s 2011 Hyundai Sonata all hot use Hot Shots engine and Tranny Fulids
Glad to hear you’re using Hot Shot Secret in your Mack with good results as well! The most noticeable difference in the Kenworth with the PX7, same block as the Cummins ISB 6.7, is the air compressor is only half as loud as it was with the factory Delo oil or Shell Rotella! The air compressor in these engines is quite loud, but the Hot Shot Secret has made not so embarrassing anymore lol. I noticed in the comments that so many people have been using some of these diesel oils in their gasoline engines, that’s something I don’t know much about? Personally I would be afraid to do that, but it’s just a matter of educating myself and experience. Anyway I just bought a 2024 Ford Maverick hybrid, and I bought Valvoline specialty hybrid oil just for it, since it’s formulated for the unique operating conditions of a hybrid engine. I’m looking forward to the first oil change on the Maverick!
@@rowmacgglad to know that it helps quite down the air compressor. Yes I use Hot Shots Blue Diamond 5w40 Diesel oil in my 2011 GMC 5.3L I just switched from there Euro 5w30 and 5w40 just because I wanted the extra additives that are Diesel Oils to help with the famous LIFTER Failures in the LS Engines For the years of the Active Fuel Management but calling placebo effect to me but makes me feel good I also use there gear oils and transmission fluid. I use Valvoline products in the pass with good success and is my backup oil or Chevron Delo Oils. But every once had there own choice it’s there money spend it how they want. Have a great one sir.
@@candyman1967 I would have 🤷♂️ no clue. Never used redline oils in general. But Hot Shot Secret is good stuff not fan boying ever . But I am trying Ultra1Plus oils now just to see cause they are priced just right look them up .
Video Idea: testing Rotella T4, T5, T6 just to see how the same brand stacks against each other. As long as ICE engines are still around, we can't wait to see ANY if your oil testing. Amazing presentation as always ! 💯
Agreed. I like Rotella but I'm also on the fence with T4,5, and 6. I know T4 is great for flat tappet engines but I've heard inconsistent reports on the T6
They're oil is impressive but try their grease, best stuff I have ever seen in my Heavy Equipment Operation/Ownership life. I knew Shaeffers would be up towards the top once I first saw it in this test.
T6 is top notch quality oil for half the price of other oils.. youll be fine with any of these oils as long as you change the oil on time every time... I will never change oils ..T6 all the way for the price and quality it has no competition @@thegarbagegladiators4735
really great comparative analysis......I have used t6 rotella in 15 40 and 5 40 with no engine mechanical or injector (HEUI) failures of any kind but have known that there are better oils to be had at substantially higher price......really appreciate how much effort you put into this analysis and presentation...clear, objective, concise....very useful....took pics of all your charts for future reference....Thanks again
Very impressive test. Well worth watching. I drove a fuel transport for 20 years. The oil company I worked for sold many different types of engine oil. Including most of what was tested. We were a Schaffer oil distributor for 70 years. That was the oil we used in all our trucks. I watched a teardown of a Detroit 60 after 1 million miles. Very impressive results.
@@vivillager people definitely runs oils too long and then blame them when something goes wrong, running rotella and changing it in a timely manner is the key. I just changed the oil on my tundra yesterday, I had amsoil signature in, it had about 11,000 miles on it. It looked brand new, almost felt bad disposing of it haha. There’s no doubt amsoil is top tier but man the price is hard to swallow.
All of your videos are so amazing. I've shown so many of my family and friends your videos. They are so well made and informative. Thank you so much for all that you do
Hi, I'm a big fan of your channel! I'm extremely disappointed though that Supertech 15w-40 Synthetic ($15 a gallon) is not tested in this video! 😔 Rotella T6 is now $26 at Walmart. Thanks for the content regardless! Hope to see it someday in the future !
Another great unbiased review that we can trust. Most oil reviews are sponsored and they are biased to their oil. Thanks for doing these reviews and keep them coming please.
Yeah lets trust a test that never uses an actual motor. THis is like using motor oil on a bike chain and expecting results.... its ENGINE OIL NOT BEARING GREASE OR LUBE!
Good to see none of these products were outright failures; the Mobil might leave something to be desired but would probably perform just fine in normal duty operations. Rotella looks like my all-around choice (it already was my recommendation before), while Amsoil seems the best for extreme duty/high heat environments.
I think really any of these oils will work great... if going with the Mobile just might have to change oil a little sooner with the smaller additive package in it. Have used Mobile quite a bit in the past and has worked great.
I never realized they started putting motorcycle pics on the Rotella. We've been using it for years in bikes. They finally caught on and promote it now.
@@ProjectFarmDo this again and add a Warren product like Kirkland Conventional 15w40 or Lubrigard(warren) Full Synth 5w40. Both are by far the cheapest priced. We have 100 10 wheel dumps running Lubrigard, both conventional and Synth depending on the season.
I know Delvac didn't finish all that well against the other brands, but I've had really good luck with it. Been driving a truck for 25+ years and have used nothing but Mobil Delvac. Never had an oil related failure.
That just means regular maintenance will benefit you no matter what oil you use. Using better oil will ultimately do even better and most likely give you more engine life long term. I personally use amsoil in everything, it is a little pricey but I have seen proof personally that it performs better.
Yeah same here, I've used T4 with outstanding results for years, especially on my wallet. Would love to see how it stacks up in lab testing. Engine results have been near perfect.
@ProjectFarm specifically an anti foaming test would be cool. I've heard although these are wet clutch certified, they don't stand up to the revs as well.
Same here. I running T6 in my bike currently. I’d like to keep running it but I’d also like to see how it compares to a full synthetic oils that are manufactured specifically for motorcycle use. I change the oil in my bike every 2,500 miles anyway. So I’m probably fine no matter what I use.
I live in cold cold Canada. I buy the cheapest oil on sale at the time I don't use a certain brand I just use the cheapest oil. I've done this for 42 years. I change my oil religiously and I've never had a problem. The important thing is to just change your oil and to never push it to far.
i live in a moderate climate in Europe and i've been doing the same for 40 years too; in my cars i always use the cheapest OIL i can find; i'm a mechanic
I live in the very moderate UK, drive low-performance cars and don't usually drive them hard. I use cheap oil and never change it (after buying the car - used - because I don't know what was in there). I do change the oil filter frequently, though. I have never had a problem attributable to oil troubles, but who knows what other cars and driving styles might show? PF's tests do indicate that even the cheap oils provide decent baseline performance, anyway.
Great testing. I used Rotella for many years in a '99 ford 7.3 Powerstroke. I recently changed to Amsoil. The engine runs better and is quieter. I'm going to continue with the Amsoil.
I’ve been running the Mobil in my early 99 7.3 that I bought brand new for about 17 years, since Rotella reformulated in 2007(ish). It has around 400,000 miles currently but I’m thinking of switching oil now.
Some of the best TH-cam content out there, IMO - robust testing, does exactly what they set out to do and communicates conclusions well to the audience. Super stuff!
Glad you chose this topic, I put Shell rotella in a jeep w/a amc 258ci, straight six. It is a gas engine but with super long stroke like a diesel. It normally calls for 10/40, so I hope it was a good choice
Shell rotella is one of the best. All of my old tractors, trucks and equipment get rotella 15-40. It’s affordable and works great. Rotella t4 also has all the additives necessary for older engines.
I bought a pail of T6 after it tested well in previous videos. It’s readily available and inexpensive where I live. I also live where it routinely gets to -40. At the price, it’s easy to increase the oil replacement schedule to keep the oil at its best.
I've been doing the same thing in my '98 grand Cherokee 4.0 for 8 years. I live in the North East, so we get temperature ranges from single digits, to over 100 degrees. Run it all year round. The old Mercedes straight six gas engine's, called for 15-40 from the factory.
I do the same with my '86 AMC Eagle with the 258ci as well as my '87 F-150 351w. Pretty much anything older with flat tappet cams have to have the extra additives.
_"Jack of all trades, master of none. Offtimes better than a master of one."_ So many people forget the second half & reverse the intent of the saying.
You work so hard for us! Im going to continue to use Rotella, but if money were no object, this would have convinced me to run something else. Im impressed with how well Rotella seems to perform for its price, in this test and others.
I ran Royal Purple for 600k miles in a 2017 6.7L Ram and was VERY pleased. I got 400k out of injectors that were still working but running a bit rough. The HUGE benefit was when I opened for the injector change there was ZERO carbon and sludge. The 2 old school mechanics there were amazed at how clean that motor was. Also to note was that my oil pressure was virtually the same as the day it started. After trading that one in for a 2023 I continued with Royal Purple. I do not mess around and when its time to change I do it. Also relied on Wix XP filters too. There was an Engine Masters show that tested a lot of the filters and the Wix XP came out on top there. I rarely run over a few hundred miles after the change light comes on. If you want your motor to last MAINTAIN IT!
The Motor Oil Geek YT Channel has in depth and scientific based knowledge of a variety of engine oils. He’s a wealth of knowledge and experience. Great post!
0:25 I always appreciate the oil testing lab, however I always wondered if not shaking the bottle will yield a difference between the additives falling to the bottom! I always shake my bottles now as I usually don't use the whole bottle (lots and lots of small engines)
Great info as always, you are definitely my favorite! Thank you. I have a 2011 f350 6.7 I was running the shell T6 for about 150k miles. I changed to TRIAX Fleet Supreme 5W-40 Full Synthetic oil (has 25k oil change intervals) I still change around 7500... I noticed a difference within the first 10 minutes of the change and the second oil change my truck was running even better. My fuel economy has increased and I get about 100 more miles between regen. It would be great if you added this oil at to your list.
Amsoil only for my 22 F450. Yes it’s expensive but worth it, especially with a bypass filter and 10k oil changes that could be taken farther with analysis. Also use 5W-40 so the cold flow difference is no issue. Have tried a couple other expensive brands and Amsoil definitely makes the engine the quietest. As long as I can afford it, I’ll never switch. Just my 2 cents of course. 🤷🏼♂️
Only 5 comments down and I found an amsoil cultist. The oil is decent, sure. But it's extremely overpriced. Regular oil changes are the key, not spending the most money on the highest priced oil on the market. That's like saying a $10 tube of toothpaste is better than a $1.99--the important thing is brushing your teeth regularly, not paying for the most expensive toothpaste.
@@SirPhilMcCrackinVonBeggington Words of common sense that everyone knows. You’ve demonstrated nor explained anything new or worthwhile. Whether you want to believe it or not, sometimes things in life that cost more ARE better and I couldn’t care less if you want to use gas station oil or not. I’ve done my own testing and analysis for myself and choose to buy Amsoil. Buy what you want and don’t put others down because you buy cheaper stuff. Makes you look a bit uneducated and simple minded.
@@SirPhilMcCrackinVonBeggington Another typical keyboard warrior trying to make yourself feel better and worth something. Carry on pal, nobody cares. Good luck 👍🏻
Your not screwing up your engine with T6, as long as you're changing it when you should! It meets the motorcycle wet clutch certification, and it's good oil for a fraction of the cost of Yama/Honda/Kawi oil. I know it's not quite the same, but there's truckers with 2million miles that swear by the stuff. I don't recommend you go cheaper (like T4/T5) as they're not full-synthetic like T6.
As an independent mobile heavy equipment mechanic, my 2014 power stroke service truck has over 300,000 miles, with thousands of extra hours of idle time on it. I change oil every 30 days regardless of mileage and fuel filters every other oil change. I use conventional Rotella T4 15W40. Because of the grotesque torture I put my truck through on nasty job sites, my theory is that more frequent oil changes with cheap oil is less damaging than extended oil change intervals with expensive oil, and I've got the high mileage truck to verify that. If you use your diesel intermittently, or run it in dirty environments, or put on tons of idle time, your oil is going to be contaminated with some combination of soot, water, fuel and dirt. Under those circumstances, your engine is not going to care how much you spent on the oil...you have to change it, often. If on the other hand, your running your truck as a hotshot, with tens of thousands of freeway miles every year, you should get the best oil that money can buy and extend that interval out as far as you can. It really all depends on what you're doing with your diesel, in my opinion. Incidentally, if you bought a diesel truck to commute 20 minutes to work and back, haul a bag of groceries on the weekend, and tow your camper once a year, sell it. You don't have any business owning a diesel truck. 🤣🤣🤣
I don't tow jack with my 17 chevy duramax! I just wanted to own a truck that has a better resale value if I decide to sell than a half ton gasser and wanted a truck that would last twice as long as a half ton gasser ! My money my investment! Arrogant tow douches should stop wasting there cry baby opions on guys who don't tow! Our money our problems not yours!
I'm not really following your logic, especially since you claim you're a mechanic and should have a better understanding of stress put on an engine. You claim that freeway haulers should invest in full synthetic? Freeway miles are proven to be the least demanding on an engine. If you need proof of that, just look at the difference between freeway fuel efficiency vs. surface street fuel efficiency. It makes more sense for highway cruisers to use conventional given the lack of stress from freeway miles. The "torture" you put yours through of idling and driving to an from and around job sites would be much much more logical application of synthetic oil, because despite your claim, your engine will absolutely perform better AND you will definitely have a higher degree of protection with a synthetic oil in a higher stress operating environment. Rotella T6 current price is an extra $6 per gallon (on Amazon anyway) which is something like an extra $24 per oil change (assuming your power stroke has a 15 qt. capacity). Further more it's a business expense for you, so it's tax deductible. All of that said, given your application there is absolutely no reason you should be cheaping out on oil for your truck.
@@SirPhilMcCrackinVonBeggington Don't disagree with a single thing you said, however, I think you may have missed the point. The kind of operating I do literally contaminates oil very quickly. I do super frequent oil changes to keep that contamination out of my engine. If I were rich, and cost were no factor, of course I'd put something much more expensive in there. Bottom line is this. Clean, cheap oil protects better than contaminated expensive oil. I've owned 3 separate Power stroke trucks over the last several years and got the same results every time. No engine repairs needed...at all.
I’m using Shell Rotella T6 5w-40* In my 2000 Cherokee 4 liter solely because of the higher ZDDP, around 1000 ppm, because the engine has flat tappet lifters. I think a comparison of oils such as these with around 1000-1200 ppm ZDDP should be tested, just not diesel engine oil. Such as the Driven brand.
12:48 concerning Additives and anti-wear detergents- Lake Speed Jr. said that lower numbers doesn’t mean anything; some oils work synergistically and since they don’t have to compete with higher sulfur fuels outside the USA, they don’t need as much calcium to neutralize the sulfuric acid that could form from the sulfur in fuel, so it leaves more % in the total volume for the base oil, which is actually the part doing the lubrication. It’s Science, not speculation! They tested multiple oils of the same brand of different viscosities to determine that A) most engine damage happens at startup and B) always prefill your oil filter.
@@jeffreycattelino3996 they claim really long oil change intervals I hope project farm tests that one day. I'm sticking to penzoil platinum for more frequent changes
I find this testing very useful as I have a Cummins. Currenlty, I run Phillips 66 Gaurdol 5-W40. I would love to see how this oil compares if you ever decide to test oil for diesels again. I do find your testing very objective and fact based. Thanks for doing these. BTW, the tests that involve your motorhome are quite funny, but yet factual!

Thank you for what you do
I have a challenge for you 12 car batterys how longbwould it take one simple altinator to charge them and would they last a full day running a heater blower motor from a house furnace and use voltage reducer like light dimmer to slow lower juice to fan
Nice comparison- one thing is the Mobil product was a synthetic blend product. To do an actual comparison against its competitors would be the delvac extreme,which I believe used to be Mobil 1 diesel. The Mobil extreme has upwards of 40% more additives and anti oxidation capabilities of the 1300.
Try brand diesel motor oils, Like John Deere, Case, New Holland, etc...
You should test different synthetic oils. Versus just normal oils.
Project Farm is still the hardest working channel on TH-cam!
Thank you!
Agree. The hours of hard work that goes into these excellent videos is greatly appreciated.
Clearly...
And with great purpose besides mere entertainment!
Bravo!
For sure!, also best test channel on TH-cam
Our whole semi fleet switched to amsoil and we've seen 30% less repairs with millions of miles tested. Use to run rotella like every shop but the results have been speaking for themselves. Great channel!
Thanks!
zero chance amzoil is making the difference
@hkfan4596 we send oil samples in ever 10k miles I can assure you it's the amsoil when we couldn't get it for a little bit during covid shortages we ran rotella and ever oil sample showed higher wear materials from bearings. The valvoline blue actually performed better than rotella. When we first switched we did half our fleet to see if cost difference was worth it in our trucks on rotella engines laster around 500 to 550k miles. Amsoil constantly hit 900k and above which is good for heavy haulers
What are your intervals if your engines last only 500k? I mean, seriously, do you do oil only once every 100k?
@@lukaswildner8040Logging trucks maybe?
It’s 3 am. I don’t own a diesel.
Thanks for watching!
😂
2am here and I don’t either😅
I've used t6 in everything from my gas cars to my lawn mowers
Too funny lol
I have a 2005 6.0 power stroke. I’ve been using Royal Purple since I bought the truck new. 575,000 miles still going strong.
Thanks for sharing.
Most impressive comment by far
Royal purple is a good oil it’s just not the best. I’ve seen so many oil tests and Royal Purple always does “ok” on the wear test.
AMSOIL. Yes its expensive but its the best. TIP: Become an AMSOIL member, it’s a low yearly fee. It gives you a massive discount on each oil purchase and rewards. You get money back fast, and save big in long run for best oil. I use it it in all my cars, trucks, and tractors so I save a lot of money.
Because of this comment, I too will use Royal Purple in my 04 6.0
I don't have any diesel engines. But oil testing is always fun to watch!
Thank you very much!
I also don't have any diesel engines, yet I use heavy duty diesel engine oils in my petrol generator and my electric air compressor (also recommend multigrade 15w40 as mentioned in it's manual)
Not just diesel, I started putting diesel oil into my gas engines 20 years ago when they started taking zinc out of engine oils. It’s kept all my old flat tappet (pre 1988ish) engines alive.
@@ThirteenTwentyRepair Yeah. Years ago I did some general farm work. Rotella not only went into the semis and big tractors but also into atv’s, mowers, welders, generators.
I just gave everybody a like 👍 👌 Now im going to read them lol
The Shell Rotella T6 has been a common oil used in the motorcycle racing community for decades. Sportbikes (Except for some Ducati's) have a wet clutch. The transmission and engine are within the same cases and share the same oil. Motorcycle specific oil can be VERY expensive so some of us started using T6 around the year 2000. As your tests show, it contains 0 Molybdenum. Thats what makes it safe for a wet clutch. Racers also change the oil often. Usually every weekend if not more so the cost savings can be significant.
My own experience is over 25,000 miles each on two Yamaha R1's with no engine, transmission, or clutch issues.
Thanks for the feedback.
Yup, back in my sport bike days it was always T6.
What year is your R1? I have a 99 that I run 15w 40 T4 in for the last 10 years or so and I love it. I don't know if it's all in my head but the transmission seems to like T4 better than T6 even though I want it to like the synthetic better. I tried Delvac 5w40 full synthetic 20 years ago and it hated it. 55K miles now on the original clutch so I love Rotella.
It's not in your head. Reviews show that many users find better shifting with the T4 over the T6.
Either one is a great oil.
What people don't know is Shell changed the formulation on the T4, Though not listed on the bottle it is now semi-synthetic and states it on their website.
Agree.....T6 is very popular in the motorcycle world....using it myself in a VFR800 and Valkyrie....
It’s so crazy how oils with the same viscosity rating act so differently in different temps. Especially the cold temps! Thanks for your great videos!
You are welcome! Good Point!
I wonder what they actually tested for viscosity compared to what the bottle says.
To my knowledge, the product viscosities are approximate. For example, brand A may be thicker than brand B, but would still fall in the same viscosity rating range, such as 5w30, etc...
THE missing variable THE MOTOR!
Lets using cooking oil and on bike bearing and expect results?
This guy does not understand anything about cars. TO test oil it must BE IN A MOTOR!
@@thatskrazy8145I see your problem, your car has a motor not an engine. This is engine oil.
I like the fact that you present the data quickly and talk fast, you're quick to the point :)
Good job.
Thanks!
Me too. I usually speed up playback to 1.5 for most all TH-camrs except ProjectFarm.
I would have liked to see the Delvac Heavy Duty Full Synthetic oil used instead of the cheaper one doesn’t seem like Apples to Apples comparison.
Shell Rotella only in this household. Two Kenworths, three John Deere field tractors, two Kubota tractors, three diesel pickups. All run this oil for years with no problems. Change any oil when you should and there will be no problems. We always change before the recommended time interval.
I agree with you to a point till you put the def and the EGR systems into play and they can wreck that idea do away with them and I'm with you
Rotella oil used here 1998 Peterbilt with a 12.7 Detroit I’ve got no complaints.
Everything in my arsenal of vehicles and engines is running 5w40 t6.
140k miles of use in my supercharged civic, and so far 50k miles in my f150 with the 2.7.
My lawn equipment gets t4.
Ditto. T6 in a Superduty 6.0 and that engine is finicky as hell.
I've always used Rotella on my 07 International 9400i with a Cat C15. Did my first rebuild at 1.4m miles. I'm just over 1.5m miles and never had an issue with the engine.

Thanks!
I use T4 on my two motorcycles. Over 30k on each. Good stuff
Schaeffer's did a customer testimony video of their oil. It was Urfer trucking company 30k oil change intervals on a 3406 cat engine. They broke the engine down at a million miles and it was spotless, still like new.
@@simonsays582 That's impressive!
Would have loved to see Chevron delo in the test
Rotella's price to performance ratio is why it's so common in fleet applications. It's not the best, but it keeps costs low in an environment with controlled service intervals. Consistent, regular oil changes are more beneficial than any additive package that exceeds OEM requirements!
Thanks for the feedback.
in fleet operations you should totally be using amsoil or pennzoil ultra prem. Those vehicles are run HARD and seriously need that oil protection.
Now if it's fleet as in car dealership sitting on the lot then obviously it's barely run at all and you can get away with anything
@@jason200912 Go work in a large corporate fleet management facility that oversees thousands of vehicles. Paying 3-4x as much at each oil change, versus the average vehicle lifespan and average repair costs over the life of the vehicle, there is absolutely no financial incentive to spend that much on oil. Factor in vehicle depreciation into this equation, and it makes even less sense. Any oil that meets manufacturer specifications is more than enough for fleet, even in a severe duty application. Oil analysis is common with large, internally-managed fleets, but only to either confirm current service intervals, or to determine if modification is required or financially beneficial.
We always used it in saabs due to the high zinc content for gas engines, but I heard that its not as high in zinc anymore.
not sure if thats true.
Yep!! 2 vehicles & 2 bikes. I buy it in bulk and change the car & truck every 4000mi & the bikes every 3k since its their manual trans gear oil too

I packed Schaeffers aerosol products back in the 1980-1990's. The head chemist was Mike Ryterski. Guy was a genius. So many different products, all top notice and a hometown company. He always put the good stuff in his products. Their compressor oil dropped our rotary screw temp by 20'F. Most unusual product was a zinc bearing goo used on huge dredging machines. 1 can to a wheel. Offset wheel device would run on a rail track, pick the whole machine up and move it 8 to 10 feet. Extreme Pressure!
Their beer isn't the same since Pabst bought them out ...
Thanks for sharing.
Schaeffers is king. I gave it a shot about 10 yrs ago on my concrete pump and it reduced my hydraulic fluid temps constantly 20+ degrees, same thing when I put it in my truck, i than got into it and started doing oil analysis, different tests, etc. schaeffers is king, with the addative moly in it, the longer u run Schaefer’s the more the molly coats everything and is a game changer when it comes to cold starts. When I went to Schaefer’s in my Allison trans it reduced my max temp i would typically see at the track where I’m really workin it, 25-30 degrees and I’m not exaggerating even a lil bit
I started out my working career as a diesel mechanic. My boss swore by shell rotella T before most of those others even existed. He showed me the difference on engine teardown. Shell engines were clean inside. The Delo engines had a thick sludge layer that had to be cleaned off. On cars it was the pennsoil that left the worst sludge behind.
That probably was the oil Pennsoil that a had a wax base?
FYI, Pennsoil and Shell is the same company
@@hid3nax they are, but they manufacture different segments of products
That is great to know. I have used Rotella oil the last 10 years got no complaints.
Thanks for sharing.
I'm 61 years old, and since I was able to use all in all of our equipment it's been nothing but Rotella.
I have rebuilt my John Deere dozer engine which had close to 9000 hours on it and it still looked good on the bottom end, not to mention all of our logging skidders they get the piss used out of them and never had any problems out of Rotella
Rotella has long been the golden standard of diesel-equipped industry.
I use Rotella in everything including my atvs,dirt bikes,Harley and Suki street bikes,pickups,zero turn,push mower,etc and I've never had any bearing,buildup or wear issues in any of them,nor in any of my big trucks throughout the decades...
I swear by Rotella and won't use anything else anymore...
Bottom line here... rotella may not be the best but it's really, really good!
Most of the real heavy duty truck repair shops carry rotella or delvac not the other brands. Good enough for me.
there is a lot that goes into great engine life. i use rotella t6 change it every 5 thousand miles, good quality oilt filter and keep the air filter changed regularly. the results have been great especially when considering i have save hundreds of dollars over the years one the price of oil.
Great oil review, I was running the 1540 Amsoil but I switched to the 5-40. It is way better at cold starts in my 6.0. Amsoil claims it has the same high temperature performance. It would be interesting to see cold run and hi temp wear between the 5-40,6X Amsoil versus 15-40,6X?!
Merry Christmas!
I have been using Mobile Delvac for years and years. Never a problem. And I run T-6 in the winter when temps are going to be Sub-Zero. I learned that from your previous video, a few years ago.
Thank you for the feedback!
I'm in norther Wisconsin. Further north than most canadians. -40° winters are normal. I have only ever run delvac. My oil analysis always comes back clean. My truck has 300k. I hardly ever plug in.
Let it run in high idle for 10 minutes and I'm good. There's no reason to spend more money for the same results.
I've run a couple trucks up to and beyond a million miles with Delvac. And they were still running fine when i got rid if them and not using any oil.
I used Delvac since I purchased my 97 7.3 power stroke. Back in 97. Change it around 4K . I've always been amazed at how clean the oil was even if I let it go 5k which is rare. Others 7.3 oil I've seen. We're black a tar. I've recently changed to mobil 1 extreme. It's a synthetic blend. Also started adding a 1/2 bottle of arch oil friction modifier. If you research oil for the 7.3. Ford actually doesn't recommend Delvac 1300 now. Stating in their testing it doesn't meet their 1,000 ppm specifications for phosphorus! I also read where Mobil changed the formulation of Delvac 1300 to meet the new CJ-4 SAE standards. No doubt this negatively affected the anti wear additives. Hopefully, all the miles that I put in my truck using Delvac. Was with the original formulation. However, this is my reason for changing . Boy !! Would I love to see the results of these test with the Arch oil AR9100 friction modifier added to them. That stuff gets amazing reviews. Mostly for injector stiction. Which I don't think I've ever had. It still looks like a winner of a product

Been using rotella t6 in all of my diesel trucks.
02 f350 7.3l powerstroke zf6. 246k miles.
03 ram 2500 5.9l cummins 48re 242k miles
05 f650 6.0l Eaton Fuller 5 speed. 96k miles.
07.5 ram 3500 DRW 6.7l cummins g56. 143k miles
08 f750 6.7l cummins Alison auto. 104k miles.
All of them (even the 6.0) are on the original block, zero blow by, healthy compression, and have never been rebuilt. I own a tree service, so they get worked hard daily hauling wood, machinery, chips etc.
Sure, other oils may be better in certain categories, but for the price, in my opinion it can't be beat.
I used to have a 93 ram w350 dually on a 5 speed. I bought it with 380k on the clock. I knew the original owner. He told me he only used t6, so I kept with it. Over the next 10 years it earned another 300k miles. I sold it just shy of 700k on it. Original rings, pistons and block. It had a different head. But I was pleased to see that it needed no cylinder work when I pulled the head to replace it.
T6 has proven itself to me. I'll probably never use anything different. Especially when the better performers are 2x more expensive.
I do use the hot shots secret diamond g56 oil in my 07.5 6 speed ram dually. Fantastic stuff.

Thank you for this video, I was hoping you would do a comparison like this years ago! I had a 2018 RAM 5500, and put about 365,000 miles on it before I switched to a 2022 Kenworth. I tried the Shell Rotella T6, Schaeffers, Amsoil 6x Signature, and the Hot Shot Secret Blue Diamond oils. I send an oil sample to Blackstone every oil change. The Hot Shot Secret performs the best out of the oils I have tried in your test comparison. I figured all of this out with the RAM, I broke in the Kenworth with the Shell Rotella T6, while doing short oil change intervals during the first few thousand miles. Then I switched over to Hot Shot Secret after about 15,000 miles. Hot Shot Secret isn’t cheap, but the data from Blackstone shows it performs the best overall. Since my livelihood depends on my truck, I only want the best oil in my truck! I’m not surprised that Hot Shot Secret flows the best in cold temperatures, as both the RAM and Kenworth start right up and run smooth in below zero temperatures using that oil!
Thank you again for this comparison, so many people will find this information very valuable!!!
@rowmacg I use hot shots as well could believe the difference when I made the switch . Only oil I use now in had my 2019 Mack Anthem go 500,000.miles no engine issues at all before I got the new truck and I unload with a PTO. But don’t remember my engine hours .2023 Mack MP7 Anthem .2011 GMC 5.3 1500 and wife’s 2011 Hyundai Sonata all hot use Hot Shots engine and Tranny Fulids
Glad to hear you’re using Hot Shot Secret in your Mack with good results as well! The most noticeable difference in the Kenworth with the PX7, same block as the Cummins ISB 6.7, is the air compressor is only half as loud as it was with the factory Delo oil or Shell Rotella! The air compressor in these engines is quite loud, but the Hot Shot Secret has made not so embarrassing anymore lol. I noticed in the comments that so many people have been using some of these diesel oils in their gasoline engines, that’s something I don’t know much about? Personally I would be afraid to do that, but it’s just a matter of educating myself and experience. Anyway I just bought a 2024 Ford Maverick hybrid, and I bought Valvoline specialty hybrid oil just for it, since it’s formulated for the unique operating conditions of a hybrid engine. I’m looking forward to the first oil change on the Maverick!
@@rowmacgglad to know that it helps quite down the air compressor. Yes I use Hot Shots Blue Diamond 5w40 Diesel oil in my 2011 GMC 5.3L I just switched from there Euro 5w30 and 5w40 just because I wanted the extra additives that are Diesel Oils to help with the famous LIFTER Failures in the LS Engines For the years of the Active Fuel Management but calling placebo effect to me but makes me feel good I also use there gear oils and transmission fluid. I use Valvoline products in the pass with good success and is my backup oil or Chevron Delo Oils. But every once had there own choice it’s there money spend it how they want. Have a great one sir.
@@nickjones8702
I wonder how it compares to Redline diesel oil? Years ago there was a test of virgin oils and Redline was hands down the best!
@@candyman1967 I would have 🤷♂️ no clue. Never used redline oils in general. But Hot Shot Secret is good stuff not fan boying ever . But I am trying Ultra1Plus oils now just to see cause they are priced just right look them up .
Video Idea: testing Rotella T4, T5, T6 just to see how the same brand stacks against each other. As long as ICE engines are still around, we can't wait to see ANY if your oil testing. Amazing presentation as always ! 💯
Yeah. I used just T4 and never a problem. Just got new truck and not sure how T4 would compare to T6
T4 is what I've wanted to see on his channel since his first oil test.
Agreed. I like Rotella but I'm also on the fence with T4,5, and 6. I know T4 is great for flat tappet engines but I've heard inconsistent reports on the T6
Rotella T4 vs against Mobil Delvac? 2 biggest choices for semi trucks!
I agree please test the Rotella family of 15-40 oils
One of the humblest TH-camrs out, great content mate. Very helpful👍🏼
Thanks! Glad it was helpful!
I've used Schaeffer Diesel motor oil for many years and have been very impressed.
Thanks for sharing.
They're oil is impressive but try their grease, best stuff I have ever seen in my Heavy Equipment Operation/Ownership life. I knew Shaeffers would be up towards the top once I first saw it in this test.

I use Rotella and after this video ....I might switch. What are your thoughts?
@@thegarbagegladiators4735rotella is junk. Tear apart a motor thats ran anything else its whole life vs rotella its whole life.
I've used Rotella T6 since i bought my truck with 82k, now it is 301,044k no issues. Idk man, has worked fine so far.@thegarbagegladiators4735
T6 is top notch quality oil for half the price of other oils.. youll be fine with any of these oils as long as you change the oil on time every time... I will never change oils ..T6 all the way for the price and quality it has no competition @@thegarbagegladiators4735
really great comparative analysis......I have used t6 rotella in 15 40 and 5 40 with no engine mechanical or injector (HEUI) failures of any kind but have known that there are better oils to be had at substantially higher price......really appreciate how much effort you put into this analysis and presentation...clear, objective, concise....very useful....took pics of all your charts for future reference....Thanks again
Thanks and you are welcome!
Very impressive test. Well worth watching. I drove a fuel transport for 20 years. The oil company I worked for sold many different types of engine oil. Including most of what was tested. We were a Schaffer oil distributor for 70 years. That was the oil we used in all our trucks. I watched a teardown of a Detroit 60 after 1 million miles. Very impressive results.
Thanks! Thanks for sharing.
Give me the rotella over any of them. Cheap. And readily available. And excellent, proven oil.
Thanks for the feedback.
@@ProjectFarmRotella t5 or t6 all day
True, the easy access and cost makes the rotella great, it’s also good oil. Amsoil is the absolute best but you pay for it.
I run Rotella on the daily, bobtail, towing overweight, never a problem in decades. I have run Amsoil, but only for seconds at a time, sledpulls
@@vivillager people definitely runs oils too long and then blame them when something goes wrong, running rotella and changing it in a timely manner is the key. I just changed the oil on my tundra yesterday, I had amsoil signature in, it had about 11,000 miles on it. It looked brand new, almost felt bad disposing of it haha. There’s no doubt amsoil is top tier but man the price is hard to swallow.
All of your videos are so amazing. I've shown so many of my family and friends your videos. They are so well made and informative. Thank you so much for all that you do
Thanks and you are welcome!
Hi, I'm a big fan of your channel! I'm extremely disappointed though that Supertech 15w-40 Synthetic ($15 a gallon) is not tested in this video! 😔 Rotella T6 is now $26 at Walmart.
Thanks for the content regardless! Hope to see it someday in the future !
You are welcome! Thanks for the suggestion.
Another great unbiased review that we can trust. Most oil reviews are sponsored and they are biased to their oil. Thanks for doing these reviews and keep them coming please.
Thanks, will do!
Yeah lets trust a test that never uses an actual motor.
THis is like using motor oil on a bike chain and expecting results.... its ENGINE OIL NOT BEARING GREASE OR LUBE!
Good to see none of these products were outright failures; the Mobil might leave something to be desired but would probably perform just fine in normal duty operations. Rotella looks like my all-around choice (it already was my recommendation before), while Amsoil seems the best for extreme duty/high heat environments.
Thank you for the feedback!
I think really any of these oils will work great... if going with the Mobile just might have to change oil a little sooner with the smaller additive package in it. Have used Mobile quite a bit in the past and has worked great.

Thanks for you honest and fair test results. I’m changing my diesel oil from Mobil to Shell. It makes sense.
You are welcome! Thanks for the feedback.
I never realized they started putting motorcycle pics on the Rotella. We've been using it for years in bikes. They finally caught on and promote it now.

That stuff is pretty good in just about anything. I used to run T6 in my Jeep 4.0 AMC straight 6 and it loved it.

This channel is one of the most scientifically comprehensive channel out there! Great research I got to say. Keep up the good job.
Thanks, will do!
I use Rotella T6 in my diesel truck. Your testing showed to not be the best, but it also showed it to be very good and affordable. Good enough for me.
Thanks for the feedback.
I agree it’s how often you change it that matters the most 😊😊😊
@@ProjectFarmDo this again and add a Warren product like Kirkland Conventional 15w40 or Lubrigard(warren) Full Synth 5w40. Both are by far the cheapest priced. We have 100 10 wheel dumps running Lubrigard, both conventional and Synth depending on the season.
I know Delvac didn't finish all that well against the other brands, but I've had really good luck with it. Been driving a truck for 25+ years and have used nothing but Mobil Delvac. Never had an oil related failure.
Thanks for the feedback.
Seems reasonable that all popular brands would be reliable and that the comparison is... "splitting hairs" as they say.
That just means regular maintenance will benefit you no matter what oil you use. Using better oil will ultimately do even better and most likely give you more engine life long term. I personally use amsoil in everything, it is a little pricey but I have seen proof personally that it performs better.
It's Dino oil, not Delvac1
Delvac1 may have been a better comparison...
As a motorcyclist that uses T6 and T4, I'd love to see them pitted against purpose made motorcycle oils.
Thanks for the suggestion.
Yeah same here, I've used T4 with outstanding results for years, especially on my wallet. Would love to see how it stacks up in lab testing. Engine results have been near perfect.
@ProjectFarm specifically an anti foaming test would be cool. I've heard although these are wet clutch certified, they don't stand up to the revs as well.
This is a great idea.
Same here. I running T6 in my bike currently. I’d like to keep running it but I’d also like to see how it compares to a full synthetic oils that are manufactured specifically for motorcycle use. I change the oil in my bike every 2,500 miles anyway. So I’m probably fine no matter what I use.
I asked for this test quite a while ago I’m just now finding it very glad to see it!!
Thanks for suggesting the video idea.
Rotella T6 is what goes in my truck. I actually use it in my big block boat engine too. Glad to see it did well.
Thank you for the feedback!
What big block? 350 or the 8.1 496?
I live in cold cold Canada. I buy the cheapest oil on sale at the time I don't use a certain brand I just use the cheapest oil. I've done this for 42 years. I change my oil religiously and I've never had a problem. The important thing is to just change your oil and to never push it to far.
Thanks for the feedback.
Truth! Best reply to and oil thread I have ever seen.
i live in a moderate climate in Europe and i've been doing the same for 40 years too; in my cars i always use the cheapest OIL i can find; i'm a mechanic
I live in the very moderate UK, drive low-performance cars and don't usually drive them hard. I use cheap oil and never change it (after buying the car - used - because I don't know what was in there). I do change the oil filter frequently, though. I have never had a problem attributable to oil troubles, but who knows what other cars and driving styles might show? PF's tests do indicate that even the cheap oils provide decent baseline performance, anyway.
@@rich8037 You must drive very cheap cars if you want to risk engine damage vs changing the oil once a year.
Great testing. I used Rotella for many years in a '99 ford 7.3 Powerstroke. I recently changed to Amsoil. The engine runs better and is quieter. I'm going to continue with the Amsoil.
Thanks! Thanks for the feedback.
I’ve been running the Mobil in my early 99 7.3 that I bought brand new for about 17 years, since Rotella reformulated in 2007(ish). It has around 400,000 miles currently but I’m thinking of switching oil now.
Some of the best TH-cam content out there, IMO - robust testing, does exactly what they set out to do and communicates conclusions well to the audience. Super stuff!
Thanks!
I know a lot of guys with older muscle cars and they love running the diesel oils. I will make sure they see this video. 👍
Thank you!
@@earlrichardson385
The newer diesel oils arent up to the task for motorcycles like they used to be. Redline Powersports is your best option
Glad you chose this topic, I put Shell rotella in a jeep w/a amc 258ci, straight six. It is a gas engine but with super long stroke like a diesel. It normally calls for 10/40, so I hope it was a good choice
Thank you very much!
Shell rotella is one of the best. All of my old tractors, trucks and equipment get rotella 15-40. It’s affordable and works great. Rotella t4 also has all the additives necessary for older engines.
I bought a pail of T6 after it tested well in previous videos. It’s readily available and inexpensive where I live. I also live where it routinely gets to -40. At the price, it’s easy to increase the oil replacement schedule to keep the oil at its best.
I've been doing the same thing in my '98 grand Cherokee 4.0 for 8 years. I live in the North East, so we get temperature ranges from single digits, to over 100 degrees. Run it all year round. The old Mercedes straight six gas engine's, called for 15-40 from the factory.
I do the same with my '86 AMC Eagle with the 258ci as well as my '87 F-150 351w. Pretty much anything older with flat tappet cams have to have the extra additives.
love the videos man i’ve been watching for years always look forward to the weekly post👍😁

Remember oil formulas will act differently under heat and loads.
There's a reason why so.many fleets run Rotella, especially the T4...because it works.

@@ProjectFarmI have been subscribed to you for a number of years. I love all the comparisons you do.
You work so hard for us! Im going to continue to use Rotella, but if money were no object, this would have convinced me to run something else. Im impressed with how well Rotella seems to perform for its price, in this test and others.
Thanks for sharing.
I ran Royal Purple for 600k miles in a 2017 6.7L Ram and was VERY pleased. I got 400k out of injectors that were still working but running a bit rough. The HUGE benefit was when I opened for the injector change there was ZERO carbon and sludge. The 2 old school mechanics there were amazed at how clean that motor was. Also to note was that my oil pressure was virtually the same as the day it started.
After trading that one in for a 2023 I continued with Royal Purple. I do not mess around and when its time to change I do it. Also relied on Wix XP filters too. There was an Engine Masters show that tested a lot of the filters and the Wix XP came out on top there. I rarely run over a few hundred miles after the change light comes on. If you want your motor to last MAINTAIN IT!
If a 2017 had 600,000 Mi on it the oil is definitely helping thanks for sharing due to the freaking EGR trashing most modern diesels
Thanks for sharing.
I thought the K&N filter beat all the filters on Engine Masters?
The Motor Oil Geek YT Channel has in depth and scientific based knowledge of a variety of engine oils. He’s a wealth of knowledge and experience. Great post!

0:25 I always appreciate the oil testing lab, however I always wondered if not shaking the bottle will yield a difference between the additives falling to the bottom! I always shake my bottles now as I usually don't use the whole bottle (lots and lots of small engines)

Great info as always, you are definitely my favorite! Thank you.
I have a 2011 f350 6.7 I was running the shell T6 for about 150k miles. I changed to TRIAX Fleet Supreme 5W-40 Full Synthetic oil (has 25k oil change intervals) I still change around 7500... I noticed a difference within the first 10 minutes of the change and the second oil change my truck was running even better. My fuel economy has increased and I get about 100 more miles between regen. It would be great if you added this oil at to your list.
Thanks! Thanks for the suggestion.
Amsoil only for my 22 F450. Yes it’s expensive but worth it, especially with a bypass filter and 10k oil changes that could be taken farther with analysis.
Also use 5W-40 so the cold flow difference is no issue. Have tried a couple other expensive brands and Amsoil definitely makes the engine the quietest. As long as I can afford it, I’ll never switch. Just my 2 cents of course. 🤷🏼♂️
Thanks for sharing.
Only 5 comments down and I found an amsoil cultist. The oil is decent, sure. But it's extremely overpriced. Regular oil changes are the key, not spending the most money on the highest priced oil on the market. That's like saying a $10 tube of toothpaste is better than a $1.99--the important thing is brushing your teeth regularly, not paying for the most expensive toothpaste.
@@SirPhilMcCrackinVonBeggington
Words of common sense that everyone knows. You’ve demonstrated nor explained anything new or worthwhile. Whether you want to believe it or not, sometimes things in life that cost more ARE better and I couldn’t care less if you want to use gas station oil or not. I’ve done my own testing and analysis for myself and choose to buy Amsoil. Buy what you want and don’t put others down because you buy cheaper stuff. Makes you look a bit uneducated and simple minded.

Thanks for sharing.
Would love to see T6 against motorcycle oils. See how bad ive been screwing up my engines.
Thanks for the suggestion.
Your not screwing up your engine with T6, as long as you're changing it when you should! It meets the motorcycle wet clutch certification, and it's good oil for a fraction of the cost of Yama/Honda/Kawi oil. I know it's not quite the same, but there's truckers with 2million miles that swear by the stuff. I don't recommend you go cheaper (like T4/T5) as they're not full-synthetic like T6.
I'm a simple man, I see a Project Farm video and I click thumbs up.
Thanks!
@@_Epictetus_ agreed
As an independent mobile heavy equipment mechanic, my 2014 power stroke service truck has over 300,000 miles, with thousands of extra hours of idle time on it. I change oil every 30 days regardless of mileage and fuel filters every other oil change. I use conventional Rotella T4 15W40.
Because of the grotesque torture I put my truck through on nasty job sites, my theory is that more frequent oil changes with cheap oil is less damaging than extended oil change intervals with expensive oil, and I've got the high mileage truck to verify that. If you use your diesel intermittently, or run it in dirty environments, or put on tons of idle time, your oil is going to be contaminated with some combination of soot, water, fuel and dirt. Under those circumstances, your engine is not going to care how much you spent on the oil...you have to change it, often.
If on the other hand, your running your truck as a hotshot, with tens of thousands of freeway miles every year, you should get the best oil that money can buy and extend that interval out as far as you can.
It really all depends on what you're doing with your diesel, in my opinion.
Incidentally, if you bought a diesel truck to commute 20 minutes to work and back, haul a bag of groceries on the weekend, and tow your camper once a year, sell it. You don't have any business owning a diesel truck.
🤣🤣🤣
I don't tow jack with my 17 chevy duramax! I just wanted to own a truck that has a better resale value if I decide to sell than a half ton gasser and wanted a truck that would last twice as long as a half ton gasser ! My money my investment! Arrogant tow douches should stop wasting there cry baby opions on guys who don't tow! Our money our problems not yours!
Thanks for the feedback.
This seems like solid advice. I dont own a diesel, but I have a few rules for how I run my car that are similar.
I'm not really following your logic, especially since you claim you're a mechanic and should have a better understanding of stress put on an engine. You claim that freeway haulers should invest in full synthetic? Freeway miles are proven to be the least demanding on an engine. If you need proof of that, just look at the difference between freeway fuel efficiency vs. surface street fuel efficiency. It makes more sense for highway cruisers to use conventional given the lack of stress from freeway miles. The "torture" you put yours through of idling and driving to an from and around job sites would be much much more logical application of synthetic oil, because despite your claim, your engine will absolutely perform better AND you will definitely have a higher degree of protection with a synthetic oil in a higher stress operating environment.
Rotella T6 current price is an extra $6 per gallon (on Amazon anyway) which is something like an extra $24 per oil change (assuming your power stroke has a 15 qt. capacity). Further more it's a business expense for you, so it's tax deductible. All of that said, given your application there is absolutely no reason you should be cheaping out on oil for your truck.
@@SirPhilMcCrackinVonBeggington
Don't disagree with a single thing you said, however, I think you may have missed the point. The kind of operating I do literally contaminates oil very quickly. I do super frequent oil changes to keep that contamination out of my engine. If I were rich, and cost were no factor, of course I'd put something much more expensive in there.
Bottom line is this. Clean, cheap oil protects better than contaminated expensive oil. I've owned 3 separate Power stroke trucks over the last several years and got the same results every time. No engine repairs needed...at all.
Sitting in my idling car right now with Rotella T6 (5W40) coursing through my engine. Love this channel....
Thank you!
I’m using Shell Rotella T6 5w-40* In my 2000 Cherokee 4 liter solely because of the higher ZDDP, around 1000 ppm, because the engine has flat tappet lifters. I think a comparison of oils such as these with around 1000-1200 ppm ZDDP should be tested, just not diesel engine oil. Such as the Driven brand.
Great suggestion! Thank you
I second this
I ran T6 in 4.0s too!

Thanks so much!
12:48 concerning Additives and anti-wear detergents- Lake Speed Jr. said that lower numbers doesn’t mean anything; some oils work synergistically and since they don’t have to compete with higher sulfur fuels outside the USA, they don’t need as much calcium to neutralize the sulfuric acid that could form from the sulfur in fuel, so it leaves more % in the total volume for the base oil, which is actually the part doing the lubrication. It’s Science, not speculation! They tested multiple oils of the same brand of different viscosities to determine that A) most engine damage happens at startup and B) always prefill your oil filter.
