I have some vintage cans of oil if you need it for research. I also was curious if the added viscosity might inhibit the newer motors that have oil pressure activated variable valve timing.
Are the UV-cured adhesives like the dentist squirts in your mouth any better on various substrates especially hard ones like plastics, aluminum than JB Weld or other high-strength adhesives (my fave is Metalset A4 but it's a niche product)
Back in the late 60's or early 70's, they drove around in our neighborhood with a STP themed street rod, and handed out STP stickers to the kids. They were like gold to us kids, and really got the name out. 😊
Back in the 60's I lived a mile from STP headquarters (on Oakton Rd in Des Plaines), and we would walk there and go into the lobby and ask the receptionist for stickers. Those stickers were everywhere in my neighborhood.
Back in the 70's I was a well indoctrinated STP believer. Those stickers really did a job on me. My father on the other hand resented any fuel or oil "aftermarket" additives calling them snake oil. Well almost all of them. He still added a dash of ethanol to the gas in the winter to prevent freezing. And if anyone wonders about that it's not really the antifreeze properties of the ethanol that you are after. With temperature changes there will be some condensation of water in the tank. As gas and water doesn't mix the water can get sucked up in the fuel system and form ice plugs. The ethanol however will mix with both gas and water allowing for a even mix and thus prevent the water from freezing. So not snake oil...

I once had an old car battery in a 2000 Dodge Caravan, and the last winter I had it? If I was still using STP in it instead of 0w20 Pennzoil Platinum, I do not think I would have gotten it started.
Originally STP was supposed to be added to old oil, midway through the oil change interval. Used in that fashion, with mineral oil it was helpful with oil viscosity breakdown and fuel dilution. Mixing it with brand new oil makes no sense. Todays synthetics hold viscosity much better. Good video, thanks. You're presentations are a pleasure to watch.

@@brandonbrown3600 But every review out there says don't do it. Motorkote works in quick AsSeenOnTV tests, but it quickly "kotes" your engine in a sludge that usually results in damage and is difficult to remove.
@@Jayda08 I think you misunderstood his point. He was saying that most testing seems to indicate that there's no benefit to adding oil treatments (such as STP) because good oil already has the necessary blend of additives right out of the bottle. I think oil does continue to improve over time, but the addition of these treatments to your crankcase is really just snake oil as long as you're using good modern oils.
Great test! Back in the day (mid 80's) I purchased a used MGB from a used car dealer. It had great oil pressure and no smoking. Changed the oil and the pressure dropped and it started smoking as the oil got older. Talked to a mechanic and he told me it was a used car dealer trick to put 2-3 cans of STP in the engine and it would temporarily boost the oil pressure and slow the smoking.
Hi, in @2000 i purchased a Holden Statesman with the holden 5.0 308 V8 - - I am in Australia. Everything was fine, but in summer stopped at the traffic lights the oil pressure guage would go to 0-5 and the oil light would go on ( love the dual guage and idiot lights ) = then the engine would stat ticking Rev the car to say 1,000 and the light would go away. Overall the engine was sound, compression was good and no smoke or oil usage The fix was Penrite 20-60 for older engines. First start up oil pressure dead cold was almost 75%, on a hot day at idle at the lights or traffic it was @ 25%, normal drive depending on rpm was 30-50% at full / normal operating temperature It was chalk and cheese, i no longer had to worry about oil pressure and being stuck in traffic or having to put the car in neural and some slight throttle to take the revs up Regards George

Back in the 1980's I used STP for assembly lube when rebuilding engines. Mostly small block chevys. Never had a failure on start up. The stuff was sticky & seemed to help protect parts on initial start up.
True story: In 1981 I had a Triumph 650 with an unknown number of miles on it, but it was a lot (maybe nearly 100k?). I ran STP in it. On a trip from LA to San Francisco with a couple friends, I broke a pushrod. Limped the bike from Big Sur to Monterey, where there had been a Triumph dealer. They no longer serviced Triumphs, so they sent me to an old guy in Carmel Valley. He repaired the bike, then gave me a long lecture on the evils of STP. According to him, the Granatelli team only actually used it as assembly lube.
@@shoominati23 Ah, the bottles of viscosity index improver... with the gears in a plastic contraption on the counter of your local auto parts store to show you how it stuck to the gears better than straight oil. Unfortunately it would aerate in the crankcase and destroy your gears much quicker.
@@ProjectFarm I'm actually watching your videos now. I love them. I sometimes forget which was the winner so when I'm going to buy something I rewatch. Love your channel
Great job on this one. Well done sir. I remember years ago, the "old" STP was super thick.... Could hardly pour it at all below 50 degrees F.... Then I can't recall if they lost a lawsuit, or "settled" a lawsuit, where people claimed it didn't do anything... Then the "new" STP came out.... I was very very curious, what your testing would show.... I can tell you, if you WANT more ZDDP in your engine, add some Lucas Engine Oil Break In additive to it.... My numbers on the Blackstone Labs test went WAY up when I started doing that.... There's a future video idea... See if Lucas Engine Oil Break In Additive does anything... You could also test Lucas's and other brands of Engine Assembly Lube.... Some people on car forums swear by that, as an additive in every oil change....
@bobwatters Older oil used to have a lot more ZDDP. They've taken it out over the years to conform to modern engine emissions standards. For older motors it's a good idea to add some. Also oil thickness requirements change with application. More load or higher horsepower applications benefit from thicker oils.
Yep, and the can from the 60's actually said to prewarm the full can and then pour it down the carb throat of a running engine to "remove harmful combustion chamber deposits". I remember doing that once to a 57 Olds my buddy had bought when it was about 8 years old. It had belonged to an old guy who never took it on the highway. He just puttered around town in it. So, my buddy shows up with this can of STP and shows me how it's supposed to remove deposits. Well, it wasn't my car, so I said sure lets give a try. Man, did that Olds smoke !!!! We had to take it out on the highway and drive it for about 30 minutes before the smoke died away. LOLOL......and it never ran any different after the "treatment". LOLOL
Seeing and hearing you open that 1981 STP can brought back good memories. With the test analysis results, you prove once again that modern full synthetic motor oil is a real marvel. Thanks PF
STP is a made for a specific purpose. That purpose no longer exists in the case of contemporary engine. It might be useful in an old cast iron engine, as a zinc additive. One idea is that because it is sticky, it might work to keep part lubricated during cold-weather startups. The opposing theory is that a thin additive like Marvel Mystery Oil would stick to parts due to its high film strength. But all of this applies to cast iron engines.
@@anonymike8280 Agreed! we used this stuff only on worn out motors that smoked! Not for use on any modern car! We are talking about a product designed for cars mad in the 1960's or before!
@@chewybrand238 All of these products were for full cast iron pushrod engines. After watching and listening to numerous videos, reading articles and considering my own experience, if someone comes into a vehicle with a dirty engine, the recourse is to change the oil and accelerate the oil change interval using either synthetic or semisynthetic as required. I don't advocate using synthetic oil in high mileage engines where it was not the original. All coventional oil is semisynthetic to a degree. I noticed at the local Walmart that the Chevron Supreme they sell is now labeled as semisynthetic. The price has not changed, which makes me think it was semi all along. The carrier oil the additives come is synthetic oil. I have that from a good source. The best oil ha-ha I have heard was the remark made by someone that if you get your oil from a _good_ refiner... I would like to know, who is going make the capital investment in a refinery just to make bad motor oil? No one makes bad oil. If they did, the volume buyers starting with the DOD and the GSA would find them out and they'd be bankrupt within months. You just have to match the specifications of the product, the specifications of the engine and the type of driving you are doing. I do all short trips and my change interval with a 2.2L Toyota four is 2800 miles on semisynthetic. No one ever damaged an engine because they changed the oil too soon.
Your videos are the ONLY ones I've seen on these subjects that make a recommendation backed up by real transparent testing the viewer can see for themselves. Also, your approach is extremely consistent - on the level of expert engineers!
I would like to sincerely thank you. I greatly appreciate your effort and love in making videos on youtube and hope that you stay healthy and strong during times as bad as these right now.

In the early 1970s and into the 1980s I used STP in high mileage engines. It basically worked as a viscosity improver or thickener and reduced smoking and oil consumption in worn engines. By the 1980s engines and motor oils improved to the point that oil burning was much less of a problem. And, of course modern engines are designed to use thinner oil. Current high quality brand name oils are so much better that adding most auto parts store oil additives is likely to degrade the performance. Despite the hype, most of these type of products are obsolete.
Back in the late 1960's I had some old cars with severely worn engines and transmissions. Using the vintage STP I kept those old cars running. The old STP is mainly an oil thickener, which was just what I needed. Did the old STP work well in cold weather? Absolutely not. The viscosity was just too high. Are modern engine oils superior to the oils of fifty years ago? Yes, absolutely. If your engine is badly worn, STP may buy your engine some time. The small engines in most lawn mowers depend on oil splash for lubrication. Does STP splash? Not much. I worked at an implement shop. I had customers try using STP in place of engine oil. That did not end well.
what I've learned over the years (and updated by watching these tests) is to use seafoam my 160K mile diesel runs beautifully and the Ford service writer (40+ years in the business) makes it a consistent talking point that I'm one of the few with a 2005 6.0 that isn't coming in on a tow truck. maintenance and the right chemicals. It also gets a very respectable 15 mpg and as soon as that drops to 14 mpg, I know I need to fix something. : ) also, the new synthetics are like computers in the crank case ... especially for Porsches (where bore score is a serious issue in some years for some engine types in their flat sixes) ... the ability of the oil to do the right job at the right temperature, the right load, the right place in the engine ... Porsche and companies like Mobil have created magic to pass emissions and keep these engines clean, now they have particulate filters and the technology is all the more taxing for oil that has to start at 0 and get to 50 in a matter of minutes and keep completely different parts of the engine (valve gear, piston rings, big end, turbos, 20 different seal types and metals and bearing speeds) ... I remember attending factory Porsche training 15+ years ago and thinking it's just a matter of a year or two and engines will have separate lubrication for each system in the engine, but the engineering decisions consistently favor oil chemistry and complex ancillary designs ... gosh, you know it's as if they'll do anything to keep selling oil ... : )
@@brightymcbrightface my first question, as the owner of a 2006 Powerstroke that I bought new in 2005 , how do you only have 160K + miles on your truck ? 🤣
One of my biggest fears is some companies come after you for exposing their snake oil. Thank you for making these videos. You are a hero we don't deserve.
My dad, who always drove big block Oldsmobiles and Buicks, put a can of STP oil treatment and a bottle of STP gas treatment in our car before each road trip. Other than one bad water pump on a ‘68 Olds he never had a break down on any of our trips. I always enjoyed the ritual of getting ready for the road.
PF flexing on us with his great videos like always, the hot plate's just too happy to be in the video once in a while that its jumping up and down for joy in its own special way
Can you do a video comparing 0w 20, 5w 30 and 0w 40. Some cars says you can used anyone you like. But there is not test that says which is better just a lot is speculation.
Thats because it depends upon engine, weather/season, how cold it gets, etc, etc. Just follow the manf's suggestion unless you really know engines, it all costs about the same.
I'm a mechanic so I'ma help you out a bit. Every car has a recommended grade of oil that you are supposed to use, but it might have a different grade that the manufacturer says can be used if you have to. Most every common new car coming off the assembly line will ask for a 0w something and that is what you absolutely need to put in your car. If it has second grade, it's more of an "if you can't get the recommended oil, you can use x in its place, this one time". Some dealerships will turn down warranty work if you use the wrong grade of oil. Believe it or not. Most shops use Carfax for all their services. If you come to my shop and have your oil changed and then go to the dealership later, they will know whether or not you used the right oil at my shop.
I've actually been using super tech high mileage full synthetic in my 1999 gmc sierra 1500, with over 260k miles and no rebuild, just regular maintenance and oil at 6k she still runs like a champ, and only smokes when cold love that oil
In 1970 I was working in a garage when a Wynn's oil salesman came in and gave us a demonstration on two well known oil additives. STP and Wynn's Friction Proofing. He had this little stand with test tubes which were filled with STP and another with Wynn's. We used our STP and he opened a can of Wynn's in front of us. He then had a small box of ball bearing which I picked two out and dropped one in each test tube. They both slowly sank to the bottom each having equal time to get coated. He then took a propane torch, with the flame between them, and heated the tubes to, just guessing, a few hundred degrees. I can't remember exactly how long he did this but I watched real close to make sure both were heated the same. We then let them cool down. Each was poured in a different small bowl. Now I was a STP fan so I called myself watching real close. And not sure if the boss and I were fooled by sleight of hand or what. The STP ball bearing was pretty well eat up. Looked bad. The Wynn's one was still slick. Me being 22 years old it definitely made a believer out of me. To this day I still have those plastic discs that you would find once in awhile in a can of Wynn's products. Has any of you followers out there, got to be old like me, seen this demonstration before?
My entire career was as a mechanic. I started out in the early seventies. I was always told that STP was an additive NOT a lubricant. It was meant to be used with regular oils. In my experience older multi-grade oils did suffer more from viscosity breakdown. STP with its "temperature activated long chain polymers" was specifically to prevent that breakdown. Some of you may recall STP's add campaign where they dipped a screwdriver blade tip into STP and had various "tough" guys try to hold the screwdriver by its tip-none could. I tried it myself and could not hold it either. I could hold a screwdriver dipped in conventional oil. Back in the day I think STP was a useful product. That being said, today I use a top of the line synthetic oil and NO additives.
I have used STP for many years- for lubricating parts turning in in the steady rest on metal lathes. Its the best lubricant I've ever found. But my newest bottle is probably 10 years old.
I had an argument with a good friend on oil additives recently, STP was one of his favorites along with Lucas, I told him maybe save some money and use bacon grease - Proud to support unbiased everyday useable scientific testing on Patreon.
@@frigglebiscuit7484 Fake news. STP won't do anything. You should already be running 15 or 20w/50 which comes with double the zinc of regular oil. GTFO, loser.
@@frigglebiscuit7484 As Todd (or Terry?) proved in this video, STP contains VERY LITTLE ZDDP (zinc). You're much better off with a zinc additive, or an expensive "racing" oil like Joe Gibbs. Rotella and Delo 400 diesel oils used to have a lot of zinc, but thanks to EPA bullshit, not anymore.
I remember when STP sponsored everything. Even in the 60's and 70's I thought - Yeah, they use STP in those race engines all right, about a teaspoon or less............
I’d like to see a strength test on brands of sockets. Like kobalt, craftsman, Mac, snap on, and why not harbor freight! If you have the capability to test the breaking point, coatings, etc.
Secret; for safety purposes, all impact tools MUST pass a minimum test before being approved to be sold as impact tools. So, say, a Harbor Freight impact socket (or extension) may not be as tough as a Snap on, but it will likely be much tougher than any standard grade socket. So use cheap impact tools for your general use, and only pull out the thin wall stuff when absolutely necessary.
I grew up with STP My dad did oIL changes at 3k miles religiously and always added STP. Then in the mid 70s in HS during my auto mechanics shop class a STP rep came in. He had a everyone take a flat blade screwdriver and dip the shift into the STP then attempt to hold it from sliding from between your fingers. Of course King Richard was the driver of choice in our household for Nascar. Almost everyone used it at the drag strip. This is in the 60s, 70s and into the 80s Thanks again for another great video brother.
When I had my shop we used S T P for rear ends in 18 wheelers , transmissions and front wheel bearings ,less down times , had a contract with 9 police cars all rear ends got 3 cans of STP topped off with 90 weight Ford rears did not have the Ford whine STP worked wonders in the old 9 inch rears
Back in the 80s I had my 71 Challenger with a high mile 318. Beating the hell out of that motor while gathering drivetrain parts for a 440 swap, I drove that motor for about another year. Had
I disagree with the notion that this will “negatively effect” your oil performance, especially if your adding mid way through an interval like 3 months into a 6 month cycle.
No need for any of that junk. Just use a high quality synthetic that's a viscosity grade thicker. No carbon buildup problems like the STP additive caused.
Thats why i love the subject. A lot of people have many different opinions of engine flushes some say they do wonders and some say they blew their motor up. I would love to see others opinions and experiences as well as tests done with them.
Super informative thank you. Oil conditioning of an engine is very important I had my CRV for 16 years (1997) (230000kms) oil changes every 6000 kms sold it to my mechanic and his youngest boy is driving it now
Years ago I worked at a compression molding facility and we molded big parts, the biggest press was a 2500 ton Erie and we heated all including the 85000 pound die to 350 degrees. The top half had push rods for pushing the part out after it molded and set, we would take small paint brushes on a pole and lube the rods every morning and the STP was honestly as thick as honey even around the heat,,, it held up better than the bottoms of our shoes walking into the metal floor of the hot press lol. Thanks for the time and honesty you give us on your videos
The STP did reduce the wear scar in the lubricity test, so I’m surprised you would dismiss it altogether. I’m wondering if there is something about it besides the additive package that explains what it does. Years ago some friends of mine that drove log trucks would add a little to their drive axles, they had temperature gauges on their axles and noticed a temperature drop after adding the STP. I do think it has it’s place, but clearly not good for every application.
Great content as usual. Enjoyed your farming (hay making vid) if you start doing at a lot on that side consider "project farming" as a 2nd channel. But if it stays testing 4:1 farming keep it all here pls. 👍❤️
Can you test a product called “Arch Oil” it’s reviews are great, and it’s promoted by some well known TH-cam channel. It had a fuel and oil additive. It’s marketed towards diesels specifically powerstroke owners. I want to know if it’s worth the money and does it actually do anything. Thanks!
The oil treatment worked wonders in my 6.0 powerstroke for stiction issues. Mine and Jeff DeMarcus' truck use high pressure engine oil to fire the fuel injectors.
I have seen an oil pan taken off of a car engine in which the owner used OLD STP religiously. It looked like a thick layer of honey in the bottom of the oil pan. I would NEVER use STP in my car unless I was in the middle of the desert and my engine had no oil in it. I would use it ONLY if it meant I wouldn't have to get out and walk. Back in the day, people used to load the engine up on an old worn-out oil burner before taking it to trade in on a new car. If you ever bought a used car doped up with STP you bought a serious problem. An unscrupulous (unethical) Used Car dealer would dope up an old clunker and sell it as a well maintained used car. There were no used car warranties or Lemon Laws in those days. It was truly Caveat Emptor... Buyer beware. This was yet another OUTSTANDING comparison video. Thank you.
now i have to wonder.....does the supertech brand of "stp" contain a different additive package (better/worse) seeing as how the motor oil flattened the stp old and new in the wear additive department? thanks for this vid. it put to rest quite a few 'old wives tales' as it were.
Thanks. Well done. I used STP combined with Mobil 1 Synthetic Oil in a Gene Berg VW air-cooled high-performance engine in 1977. The STP helped cushion the engine's reciprocating action.

@@xn7331 I consideres that it could be thermal cycle warping, but I'm surprised it was so significant given the rather modest weight load and thermal range involved 🙂
I had to laugh at the flow test. I remember years ago when I put that STP treatment in my engines. I had to either use a spatula or leave the container in a large funnel in the valve cover and let it ozze down for hours. I agree, the newer is not as thick as the old.
Thank you, this surprized me. I used stp when I was very much younger. You sort of blew out my sails! I really will not buy it to think it will perform some miracle. that it most certainly will not.

The lab results can't be but the wear scar also has a lot to say. Contradicting results.

You've confirmed what experts have been telling us... That good oil doesn't need additives, generally.
Thanks for sharing.
True. Though motorkote testing on a older video showed great results for wear and may be one additive worth using.
@@brandonbrown3600 But every review out there says don't do it. Motorkote works in quick AsSeenOnTV tests, but it quickly "kotes" your engine in a sludge that usually results in damage and is difficult to remove.
@@Jayda08 I think you misunderstood his point. He was saying that most testing seems to indicate that there's no benefit to adding oil treatments (such as STP) because good oil already has the necessary blend of additives right out of the bottle. I think oil does continue to improve over time, but the addition of these treatments to your crankcase is really just snake oil as long as you're using good modern oils.
As someone born in 1981, hearing an oil from that time being called vintage is a kick in the junk. Good video by the way haha.
Thank you!
Great test!
Back in the day (mid 80's) I purchased a used MGB from a used car dealer. It had great oil pressure and no smoking. Changed the oil and the pressure dropped and it started smoking as the oil got older. Talked to a mechanic and he told me it was a used car dealer trick to put 2-3 cans of STP in the engine and it would temporarily boost the oil pressure and slow the smoking.
Thanks!

Hi, in @2000 i purchased a Holden Statesman with the holden 5.0 308 V8 - - I am in Australia.
Everything was fine, but in summer stopped at the traffic lights the oil pressure guage would go to 0-5 and the oil light would go on ( love the dual guage and idiot lights ) = then the engine would stat ticking
Rev the car to say 1,000 and the light would go away.
Overall the engine was sound, compression was good and no smoke or oil usage
The fix was Penrite 20-60 for older engines.
First start up oil pressure dead cold was almost 75%, on a hot day at idle at the lights or traffic it was @ 25%, normal drive depending on rpm was 30-50% at full / normal operating temperature
It was chalk and cheese, i no longer had to worry about oil pressure and being stuck in traffic or having to put the car in neural and some slight throttle to take the revs up

Back in the 1980's I used STP for assembly lube when rebuilding engines. Mostly small block chevys. Never had a failure on start up. The stuff was sticky & seemed to help protect parts on initial start up.
Thanks for sharing.
True story:
In 1981 I had a Triumph 650 with an unknown number of miles on it, but it was a lot (maybe nearly 100k?). I ran STP in it. On a trip from LA to San Francisco with a couple friends, I broke a pushrod. Limped the bike from Big Sur to Monterey, where there had been a Triumph dealer. They no longer serviced Triumphs, so they sent me to an old guy in Carmel Valley.
He repaired the bike, then gave me a long lecture on the evils of STP. According to him, the Granatelli team only actually used it as assembly lube.
I used to use a thing called 'Motor Honey' for assembly lube, but they stopped carrying it around me
@@shoominati23 Ah, the bottles of viscosity index improver... with the gears in a plastic contraption on the counter of your local auto parts store to show you how it stuck to the gears better than straight oil. Unfortunately it would aerate in the crankcase and destroy your gears much quicker.

Great job on this one. Well done sir.
I remember years ago, the "old" STP was super thick.... Could hardly pour it at all below 50 degrees F....
Then I can't recall if they lost a lawsuit, or "settled" a lawsuit, where people claimed it didn't do anything...
Then the "new" STP came out.... I was very very curious, what your testing would show....
I can tell you, if you WANT more ZDDP in your engine, add some Lucas Engine Oil Break In additive to it.... My numbers on the Blackstone Labs test went WAY up when I started doing that....
There's a future video idea... See if Lucas Engine Oil Break In Additive does anything... You could also test Lucas's and other brands of Engine Assembly Lube.... Some people on car forums swear by that, as an additive in every oil change....
It would stop up oil filters too. Bet that's why they changed it
Thanks for the video idea.
@bobwatters Older oil used to have a lot more ZDDP. They've taken it out over the years to conform to modern engine emissions standards. For older motors it's a good idea to add some. Also oil thickness requirements change with application. More load or higher horsepower applications benefit from thicker oils.
Amsoil has Z Rod oil for engines that benefit from lots of zinc.
Yep, and the can from the 60's actually said to prewarm the full can and then pour it down the carb throat of a running engine to "remove harmful combustion chamber deposits". I remember doing that once to a 57 Olds my buddy had bought when it was about 8 years old.
It had belonged to an old guy who never took it on the highway. He just puttered around town in it. So, my buddy shows up with this can of STP and shows me how it's supposed to remove deposits. Well, it wasn't my car, so I said sure lets give a try. Man, did that Olds smoke !!!!
We had to take it out on the highway and drive it for about 30 minutes before the smoke died away. LOLOL......and it never ran any different after the "treatment". LOLOL

You are welcome!
STP is a made for a specific purpose. That purpose no longer exists in the case of contemporary engine. It might be useful in an old cast iron engine, as a zinc additive. One idea is that because it is sticky, it might work to keep part lubricated during cold-weather startups. The opposing theory is that a thin additive like Marvel Mystery Oil would stick to parts due to its high film strength.
But all of this applies to cast iron engines.
@@anonymike8280 Agreed! we used this stuff only on worn out motors that smoked! Not for use on any modern car! We are talking about a product designed for cars mad in the 1960's or before!
@@chewybrand238 All of these products were for full cast iron pushrod engines. After watching and listening to numerous videos, reading articles and considering my own experience, if someone comes into a vehicle with a dirty engine, the recourse is to change the oil and accelerate the oil change interval using either synthetic or semisynthetic as required. I don't advocate using synthetic oil in high mileage engines where it was not the original.
All coventional oil is semisynthetic to a degree. I noticed at the local Walmart that the Chevron Supreme they sell is now labeled as semisynthetic. The price has not changed, which makes me think it was semi all along. The carrier oil the additives come is synthetic oil. I have that from a good source.
The best oil ha-ha I have heard was the remark made by someone that if you get your oil from a _good_ refiner... I would like to know, who is going make the capital investment in a refinery just to make bad motor oil? No one makes bad oil. If they did, the volume buyers starting with the DOD and the GSA would find them out and they'd be bankrupt within months.
You just have to match the specifications of the product, the specifications of the engine and the type of driving you are doing. I do all short trips and my change interval with a 2.2L Toyota four is 2800 miles on semisynthetic. No one ever damaged an engine because they changed the oil too soon.
@@anonymike8280 yes, change oil more often if you want it to last... sound advice
Moral of the story: Use super tech as an additive to your engine oil.

This was an eye opener. Everyone knows, and some trust, the STP brand. I've never been one but this video was great to watch. Thanks!
In the early 1970s and into the 1980s I used STP in high mileage engines. It basically worked as a viscosity improver or thickener and reduced smoking and oil consumption in worn engines. By the 1980s engines and motor oils improved to the point that oil burning was much less of a problem. And, of course modern engines are designed to use thinner oil. Current high quality brand name oils are so much better that adding most auto parts store oil additives is likely to degrade the performance. Despite the hype, most of these type of products are obsolete.
Thanks for sharing.

Warped Perception: bring the phantom camera! - some of these tests could be interesting in supper slow motion
Back in the late 1960's I had some old cars with severely worn engines and transmissions. Using the vintage STP I kept those old cars running. The old STP is mainly an oil thickener, which was just what I needed. Did the old STP work well in cold weather? Absolutely not. The viscosity was just too high. Are modern engine oils superior to the oils of fifty years ago? Yes, absolutely. If your engine is badly worn, STP may buy your engine some time. The small engines in most lawn mowers depend on oil splash for lubrication. Does STP splash? Not much. I worked at an implement shop. I had customers try using STP in place of engine oil. That did not end well.
Thanks for sharing.
what I've learned over the years (and updated by watching these tests) is to use seafoam
my 160K mile diesel runs beautifully and the Ford service writer (40+ years in the business) makes it a consistent talking point that I'm one of the few with a 2005 6.0 that isn't coming in on a tow truck. maintenance and the right chemicals. It also gets a very respectable 15 mpg and as soon as that drops to 14 mpg, I know I need to fix something. : )
also, the new synthetics are like computers in the crank case ... especially for Porsches (where bore score is a serious issue in some years for some engine types in their flat sixes) ... the ability of the oil to do the right job at the right temperature, the right load, the right place in the engine ... Porsche and companies like Mobil have created magic to pass emissions and keep these engines clean, now they have particulate filters and the technology is all the more taxing for oil that has to start at 0 and get to 50 in a matter of minutes and keep completely different parts of the engine (valve gear, piston rings, big end, turbos, 20 different seal types and metals and bearing speeds) ... I remember attending factory Porsche training 15+ years ago and thinking it's just a matter of a year or two and engines will have separate lubrication for each system in the engine, but the engineering decisions consistently favor oil chemistry and complex ancillary designs ... gosh, you know it's as if they'll do anything to keep selling oil ... : )

Thats because it depends upon engine, weather/season, how cold it gets, etc, etc.
Just follow the manf's suggestion unless you really know engines, it all costs about the same.
I'm a mechanic so I'ma help you out a bit. Every car has a recommended grade of oil that you are supposed to use, but it might have a different grade that the manufacturer says can be used if you have to. Most every common new car coming off the assembly line will ask for a 0w something and that is what you absolutely need to put in your car. If it has second grade, it's more of an "if you can't get the recommended oil, you can use x in its place, this one time". Some dealerships will turn down warranty work if you use the wrong grade of oil. Believe it or not. Most shops use Carfax for all their services. If you come to my shop and have your oil changed and then go to the dealership later, they will know whether or not you used the right oil at my shop.

Thanks for the feedback.
In 1970 I was working in a garage when a Wynn's oil salesman came in and gave us a demonstration on two well known oil additives. STP and Wynn's Friction Proofing. He had this little stand with test tubes which were filled with STP and another with Wynn's. We used our STP and he opened a can of Wynn's in front of us. He then had a small box of ball bearing which I picked two out and dropped one in each test tube. They both slowly sank to the bottom each having equal time to get coated. He then took a propane torch, with the flame between them, and heated the tubes to, just guessing, a few hundred degrees. I can't remember exactly how long he did this but I watched real close to make sure both were heated the same. We then let them cool down. Each was poured in a different small bowl. Now I was a STP fan so I called myself watching real close. And not sure if the boss and I were fooled by sleight of hand or what. The STP ball bearing was pretty well eat up. Looked bad. The Wynn's one was still slick. Me being 22 years old it definitely made a believer out of me. To this day I still have those plastic discs that you would find once in awhile in a can of Wynn's products. Has any of you followers out there, got to be old like me, seen this demonstration before?

Do you feel sexually repressed?
@@Jimmy-sj9ny whut does that meen??
My entire career was as a mechanic. I started out in the early seventies. I was always told that STP was an additive NOT a lubricant. It was meant to be used with regular oils. In my experience older multi-grade oils did suffer more from viscosity breakdown. STP with its "temperature activated long chain polymers" was specifically to prevent that breakdown.
Some of you may recall STP's add campaign where they dipped a screwdriver blade tip into STP and had various "tough" guys try to hold the screwdriver by its tip-none could. I tried it myself and could not hold it either. I could hold a screwdriver dipped in conventional oil. Back in the day I think STP was a useful product. That being said, today I use a top of the line synthetic oil and NO additives.
Who laughed when the engine started smoking right away with stp.

I think older SK are virtually unbreakable.
Secret; for safety purposes, all impact tools MUST pass a minimum test before being approved to be sold as impact tools. So, say, a Harbor Freight impact socket (or extension) may not be as tough as a Snap on, but it will likely be much tougher than any standard grade socket. So use cheap impact tools for your general use, and only pull out the thin wall stuff when absolutely necessary.

My dad did oIL changes at 3k miles religiously and always added STP. Then in the mid 70s in HS during my auto mechanics shop class a STP rep came in. He had a everyone take a flat blade screwdriver and dip the shift into the STP then attempt to hold it from sliding from between your fingers.

I disagree with the notion that this will “negatively effect” your oil performance, especially if your adding mid way through an interval like 3 months into a 6 month cycle.
No need for any of that junk. Just use a high quality synthetic that's a viscosity grade thicker. No carbon buildup problems like the STP additive caused.
Try Motorkote rather than STP.

11:16 made me laugh lol you know it’s an oils thickener when the entire viscosity is “classified as thick”.
Thanks for watching.
Like a Kardashian Booty XD
The STP did reduce the wear scar in the lubricity test, so I’m surprised you would dismiss it altogether. I’m wondering if there is something about it besides the additive package that explains what it does. Years ago some friends of mine that drove log trucks would add a little to their drive axles, they had temperature gauges on their axles and noticed a temperature drop after adding the STP. I do think it has it’s place, but clearly not good for every application.
Thanks for sharing.
Back in the day I used STP as assembly lube (mainly for main seals but also in the bore before inserting the pistons), worked really great.
Thanks for sharing.
I'd think it would help more in a pressure-lubricated engine than a splash-lube engine like that.
Great content as usual. Enjoyed your farming (hay making vid) if you start doing at a lot on that side consider "project farming" as a 2nd channel. But if it stays testing 4:1 farming keep it all here pls. 👍❤️
Great suggestion! Thank you very much!
Can you test a product called “Arch Oil” it’s reviews are great, and it’s promoted by some well known TH-cam channel. It had a fuel and oil additive. It’s marketed towards diesels specifically powerstroke owners. I want to know if it’s worth the money and does it actually do anything. Thanks!
Thanks for the video idea.
It helped my 7.3 fuel injector stiction issues.
The oil treatment worked wonders in my 6.0 powerstroke for stiction issues. Mine and Jeff DeMarcus' truck use high pressure engine oil to fire the fuel injectors.
I'd enjoy arch oil vs the hot shot stiction eliminator
Agreed, powerstrokehelp.com says that the archoil helps, I agree do a test on it
I have seen an oil pan taken off of a car engine in which the owner used OLD STP religiously. It looked like a thick layer of honey in the bottom of the oil pan.
I would NEVER use STP in my car unless I was in the middle of the desert and my engine had no oil in it. I would use it ONLY if it meant I wouldn't have to get out and walk.
Back in the day, people used to load the engine up on an old worn-out oil burner before taking it to trade in on a new car. If you ever bought a used car doped up with STP you bought a serious problem.
An unscrupulous (unethical) Used Car dealer would dope up an old clunker and sell it as a well maintained used car.
There were no used car warranties or Lemon Laws in those days. It was truly Caveat Emptor... Buyer beware.
This was yet another OUTSTANDING comparison video. Thank you.
Thanks so much!
now i have to wonder.....does the supertech brand of "stp" contain a different additive package (better/worse) seeing as how the motor oil flattened the stp old and new in the wear additive department?
thanks for this vid. it put to rest quite a few 'old wives tales' as it were.
Thanks for watching.
engine oils have an industry standard that they HAVE to meet or exceed. oil additives dont have a standard to meet.
Thanks. Well done. I used STP combined with Mobil 1 Synthetic Oil in a Gene Berg VW air-cooled high-performance engine in 1977. The STP helped cushion the engine's reciprocating action.
Thanks for sharing.
I had a friend back in the mid 80's he swore by STP with his old Accord and it ruined his motor at the end, he used too much STP.
Thanks for sharing.

I’m wondering if there is something about it besides the additive package that explains what it does. Many years ago some log truck drivers I knew would add a little to their drive axles. They had temperature gauges on the axles and noticed that the temperature would come down some. I do think it’s good stuff, but not necessarily good for every application.
It altered his piston head alignment and wreaked his walls it sounds like
Todd, here I am again a year later watching this video ….. love your channel!! My previous comment still stands.
Thanks!
3:01 cracking a cold one with the boys
Thank you
@Patrick Wright yeah but you'll be able to crap fudge logs sideways before you go
@Patrick Wright what you mean? I drink one for breakfast everyday 😉
"Now THAT'S a lot of carbon build up!!!" The flex seal guy had better get scared cause you're coming for his job!! hahah
lol. Thank you!!
Didn't PF crack an engine in half and tested if flex seal could keep it together or something? I know he's used flex seal on an engine for something before 🤔
cocodojo It was on an engine head IIRC
STP executives after watching this video, "Well crap!"
Thanks for watching.
There's people who pay attention to detail, and then there is Project Farm!! When I seen freezer, I thought this dude don't play!!! Very informative. Great video!!
Thanks and you are welcome!
You should test which 1/4" hex to 3/8" or 1/2" square drive is the strongest, I always end up breaking mine
Thanks for the video idea.
Evan Smillie When we chanced the oil and filter on my dads recently bought Volvo XC70 we had to take down the plastic protector on the bottom. And in all that oily crud was a 10 mm spanner 😂🤣 the guy that lost that must have gone crazy
DeWalt .... hands down longest lasting I've ever used ..... would be nice to know if there's a brand that's cheaper but still tough
Those DeWalts are crazy expensive
Project farm: we're testing oil today!
Coffe pot: 😳
Thanks for watching.
The real question is what does he use to clean them? They are cleaner than any coffee pot ive ever seen haha
@@ProjectFarm at 3:33 , I see there are minutes gone by while the hotplate and pots are (seem) untouched. But the hotplate is slowly (in real time) flexing up and down. What's going on there?
@@pr0xZen the hotplate cycles on and then off once it reaches max temp constantly so in timelapse you're able to see the hotplate warping from heating and cooling
@@xn7331 I consideres that it could be thermal cycle warping, but I'm surprised it was so significant given the rather modest weight load and thermal range involved 🙂
I had to laugh at the flow test. I remember years ago when I put that STP treatment in my engines. I had to either use a spatula or leave the container in a large funnel in the valve cover and let it ozze down for hours. I agree, the newer is not as thick as the old.
Thanks for sharing.
Thank you, this surprized me. I used stp when I was very much younger. You sort of blew out my sails! I really will not buy it to think it will perform some miracle. that it most certainly will not.
