Have to disagree about only using regular octane petrol (gas). Most cars I've seen that state they require premium fuel will run fine for a short time on regular fuel, but not for a long time. E.g. BMW's 1.5 litre 3-cylinder turbo petrol - we occasionally see these in our shop with cracked pistons, and it has only ever happened in cases where the customer admitted they ran regular fuel instead of premium. Same thing with VW's 1.4 TSI 4-cylinder twincharged petrol engine (e.g. the high powered turbo AND supercharged version of the engine) - they occasionally come in and we find cracked pistons and the customer always admits to using regular fuel. If the manufacturer claims the engine REQUIRES premium fuel, USE IT! The manufacturer knows best.

[@nonope1774]

I guess Scotty isn't expecting that most viewers are driving German Turbo cars. He did mention putting higher octane gas in turbo cars. I totally agree. Run the recommend gas for your car. Especially if it is boosted.

If the manufacturer recommends it then that's different. Very few do these days and only then on certain high-performnace models.

i love Scotty but, but hes not always correct, its a know flaw of small engine petrol cars to be prone for precognition that results in damaging the engine its common knowledge here in EU. But i doubt he works on those engines at all since he live in USA so u have to watch content of Scottys channel and having in the mind hes talking for the USA scenarios not the EU, he doesn't really know much about EU. Those turbocharged small engines supposed to work on regular and premium gasoline (ecu detects the gasoline used and adjust timing) thing is engines like to break a hole by the piston when people use regular gasoline on them ;). Hes also wrong about the ceramic oil additives, those were tested and actually working good, the guy who tested it wanted to prove they do not work but it went out they do work well, after all who would care for the car longevity? car manufactures that don't approve those additives in first place or the customers?

Finally. A accurate answer to the question I see all the time. Higher octane gas in a modern car with VVT will improve the performance of the vehicle. No, it is not needed, but it does improve the performance and horsepower in modern engines if that’s what your trying to achieve. No, it probably won’t improve mileage as if your looking for more power your probably not going to keep your foot off of the pedal. Thanks for knowledgeable and correct information.

Another specialty situation where you want to let air out of your tires: beach driving. If you come up on soft sand, drop the psi to 12-15. Makes for a wider footprint, spreads the weight out more and helps you stay up on the sand without digging in.

Scotty nailed it again! The time you should steer clear from factory air pressure settings in your tires is if you're racing the car. When racing you might want to run a slightly lower air pressure because of the extreme heat generated when racing. We used to run nitrogen at 25psi cold in Corvette tires and we tried to keep the ideal pressure when they warmed up. For normal driving definitely go with the factory settings

Scotty is spot on with his myth busting. The only additive I can recommend is ENGINE RESTORE for your oil. I have been a mechanic for 40 years and in at least four newly bought cars that were burning a little oil, after putting in Engine Restore, within about 500 miles the smoke stopped or was reduced to the point it was hardly noticeable. This was not a lot of smoke but rather when you would first take off and you would get a brief period of blue smoke out the tail pipe.

[@mummytoe]

I have used restored for many years and I stand by it's ability to limit engine wear and oil consumption . It has also helped my four bangers run more smoothly . However DO NOT. Use it in ANY. VVT engines . It can cause really expensive failure's .

@C-Bomb Thanks

[@SK-xi3ph]

Scotty, seems like you haven't tried Liqui Moly's Ceratec. It is an excellent oil additive and I have been using it on my own cars for many years now. It reduces engine friction (noticeably, with more power both on the dyno as well as in the streets) and gives at least 1.5-2 km/l better gas mileage than the regular oils. This additive, once put into the engine, can last upto 10 oil changes before you have to put it in again. I mentioned it in another comment under one of your other older videos too but seems like you couldn't get to read that.

[@wutdadilyo]

Hey Scotty! You’re absolutely right about all these car myths. For my turbocharged Subaru, It states to use 91 octane or higher for my car. I notice this with a lot of turbocharged engines needing to use higher octane gas. Thanks again for a great video.

Older Mercedes,. 300E, recommended a 6 psi increase for high loads at sustained Autobahn speeds. This is not, however, in the owner's manual of my 2014 550e. The door label shows only one pressure, but this is a speed limited US spec car.

Lol softer (low air pressure) tires pick up nails better? That's a new one. Defies the laws of physics.

[@bryanfullerton1566]

@Catharsis decreased pressure allows the tire to form around any object including sharp objects. It has nothing to do with temperature. If your tires are that hot they are done anyway. Regardless the main resistance to punctures does not come from the rubber but from the cords in the tire. Thus the reason a 10 ply tire resists punctures better than an average P tire. If a roofing nail, usually 3/4 inch or less, gets run over by an 8 psi 35 inch tire it is less likely to be punctured due to the tire forming around it while the rest of the tire remains in contact with the ground supporting the weight of the car. Up that pressure to 35 psi and the nail will be pushed straight through due to increased pressure on the nail. Also the increased area is longitudinal and does more to support my explanation since the tire is going to move over it regardless and it shows the decreased surface area pressure.

[@consaka1]

@Catharsis Yes and increased area means decreased pounds per square inch. A sharp nail still requires a certain pressure "lbs per square inch" to puncture any tire. More pressure for a LT tire but still. Since it is the cords that do the majority of resisting puncture the temperature is a very minor factor. Its call physics. By what laws is your logic? AOC? Bernie Sanders? Hilliary? Obama? Thanks but you can apply all the politics you want to "YOUR" physics to try to justify your logic but I think I'll go with the OP's application of the laws of physics. It makes more sense and I have seen it for myself.

[@BsUJeTs]

Scotty is absolutely right about transmission fluid. I had a 2004 Honda Odyssey. I use to change the fluid per the owners manual recommendations. The manual was very specific on using Honda Fluid. It stated that if you used another companies fluid, you would had to flush it with Honda Fluid. My transmission lasted until 216000 miles. The Transmission was then overhauled and I sold it. The vehicle is still going strong. I sold it with 285000 miles on it.

[@zacmich6472]

If you changed the ATF according to the older manuals (every 15k miles) instead of what they tell you now: 60k maybe you wouldn't even need to repair the transmission! They now extend the service intervals in order to shorten their reach to your pockets.....

[@Mark-zu6oz]

NEVER use a transmission fluid that doesn't contain any ingredients!

[@robbbarnett4978]

I had an 89 VW Fox I bought brand new and started purchasing an oil additive that the VW dealer sold. I used it in every oil change. It was called something like Kryx. It was a graphite formulation. I got over 300k Miles on the 1.8 liter engine that never burned oil and had nothing more than the main seal replaced. When the dealer stopped carrying this additive I used something else that basically stripped and cleaned it out and the engine then began to have issues and blow by. It goes to show you that some additives do work for the simple fact they enhance and improve metal surfaces for less friction. Havnt found anything that worked quite like that stuff did.

[@Sam_Eassa]

My 1998 V6 Camry with the 1MZ-FE motor clearly states in the user manual that premium gas is recommended. Low octane gas will reduce power. That's all I ever put in it since new and I have 320,000 miles on it and it runs like new.

I seriously hate to disagree with the master, but I have a 2002 Mazda Tribute that was using 1 quart of oil every 1000 miles, not great, but then at 180k miles started smoking real bad when I cranked it after sitting a few hours - kind of embarrassing leaving work with my fellow employees in a cloud of smoke. I was a gnat's whisker away from getting rid of it until I read some pretty good reviews about Restore Engine treatment. I figured for $8, it was worth a shot, so I added 1 quart (8 cylinder can) to my next my oil change and every oil change since and it now has ~ 250k miles, doesn't smoke and uses maybe a 1/2 quart between changes. That only started recently, for the longest it didn't use any oil between changes. Maybe I just lucked up and YMMV.

I'm not for or against all those additives, a good many do exactly what they say. The problem comes comparing cost to the marginal utility of it. I'll do Slick 50 as an example. It does reduce engine friction, it does lower engine temps, it doesn't maintain protection or benefits once drained. It won't lower temps enough to overcome a bad cooling system, it doesn't lower friction enough to show a noticeable difference on gas mileage and if used consistently, it costs more than a rebuild. Special cases to justify - Racing where that 0.01% improvement can make a win or that rare or vintage car that are irreplaceable or it would be very expensive to rebuild. Octane booster against - It costs less to just stop buying cheap gas For - You bought the only gas available and your classic car, RV or whatever starts rattling and/or running hot.

Putting engine flush through the engine can break the crud loose and stop up the ports. This will ruin your engine...I know first hand

[@honestycounts9352]

Yeah, that's true. If you have crud in the engine, the best thing to do is to use 100% synthetic oil as that will SLOWLY remove the crud over 6 to 10 oil changes, not removing it all at once.

[@epsorks]

@@honestycounts9352 correct

[@tracyp1922]

I think there is something to this. Years ago my brother told me about a guy he worked with that never changed his oil - just topped it off when it was low. So anyway, when he finally changed the oil the engine locked up.

[@scotturich]

Agree with you on most of these myths except the Gas, as you stated in the previous myths you should follow the manufacturer recommendation on fluids, Gas is no different if your vehicle is designed for HO fuel then use it if it’s designed for 87 octane use that. The engine computer systems are designed make sure detonation happens at a certain point and by not putting the correct fuel in your car you will be messing with that detonation with in the engine potentially causing more harm to the engine then good

[@392nightrunner]

My hemi gets 20 mpg with 87 octane and 24.5 with 89 octane. tested over the course of 4,000 miles.

Honda CRV- Rear differential fluid. Follow the manufacturers recommendation. Just saying.

[@barryervin8536]

Follow the manufacturer's recommendations for all fluids in all vehicles. You don't have to use a specific brand, but you have to use something that meets the specific standards called for in the owners manual. I've seen many engines, transmissions, brake systems, etc. ruined by people putting the wrong fluid in them.

[@PrinceKlutz]

Huh? CR-V's don't have rear differentials....oh, I see. Sarcasm.

[@barryervin8536]

All wheel drive CR-Vs have rear differentials. Front wheel drive CR-Vs obviously don't.

It made a difference with carburetors. Sunoco used to have something like 6 grades at every pump.

Scotty says: The manufacturer knows the car! Use their recommended motor oil! tire air pressure! and transmission fluid! But you can just ignore their recommended gasoline. Huh?

[@Jetmech1781]

My thoughts, exactly. My owner's manual specifies mid grade fuel, so that's what I use. Can the computer compensate for other octane? Of course. Does it run like absolute garbage and get horrible fuel mileage for a half tank while doing so? Absolutely.

[@karlrovey]

He's talking about the vast majority of cars that call for regular (87 octane). If your car calls for 89 octane or 91 octane, follow that recommendation. If your car calls for regular, running plus or super won't make it run better.

I find my tires wear evenly at 36-38 psi. full contact is safer and lasts longer so I'm gonna go with that instead of 33 psi.

[@heyinway]

Every tire has a shape (tire mfg call it an "envelope") that it is designed to be most efficient at. If you can find the manufacturers chart for that, you match weight that tire is carrying and tire pressure. Otherwise you have to experiment with the pressure, which isn't a bad thing...better then just blindly ruining tires.

[@donabrahamson7922]

Back when... cars always called for 32 psi. Then on lite trucks started requiring 35. Got a 2001 crv, tires call for 33, door jamb calls for 26 !! 33 bounces all over but 26 seems to work the transmission(automatic) I run about 29-30 but still not sure the jamb spec isn't from the rollover lawsuits. Any insights ??
