Auto Repair & Maintenance : How to Purchase the Right Gasoline

[eltrouble]

Just put in the recommended octane for your vehicle by looking in the owner's manual...how difficult could that be?

And why is one of the top-rated comments on this video from a guy who has no idea what octane does? He can't spell volatility.

It say 87 or better!

I put 89 or 91 octane. Is that okay for 4Runner? 3.4L V6

If you put higher octane fuel in your engine, what 's gonna happen is this: your engine valves will get really pwned and soon enough your engine ill lose its compression. That leads to loss in power and erratic behavior. So watch out what type of gasoline you put in your engine. And by all means don't put Diesel in a petrol engine or petrol in a Diesel engine.

higher octane doesn't help you if your car doesn't need it. Higher octane gas has more volitalness (if thats even a word). Basically, if you put 87 octane in a corvette, it will cause knocking, or premature detonation, which will pretty much ruin your engine.

@simracr94

Manual say 87 or better!!

In the USA got 3 kinds 87 89 and 91 Octanes

How about "better" I use 89

Or every 3 months 1 full tank with 91 Octanes

* 87 or better??

@simracr94 higher compression static or dynmic up to a certin point requires a higher octane thats why turbo, supercharged engines use 91 or higher and why higher compression engines on luxery cars use higher octane

[bennydollar]

that was nothing

I thought that he was gonna look under the hood or do some diagnostic test.

People keep saying that it doesn't make a difference what fuel you use in your car. Those people are retarded. The higher octane fuel keeps your system cleaner making the engine last longer with less need for tune up type maintanence. With higher octane, you also get a quieter ride and better performance. But if you are trying to save money, then go with the lower octane. Especially if you are not interested in keeping the car more than 10 years or running at top performance.

Your right, I had an engine in my Corolla stuff up. the mechanic reckoned it was because the ordinary unleaded fuel in Australia didnt have a high enough octane and I should use the premium unleaded. It does make a difference to performance, with less depression of the accelerator pedal to get to the same speed, a smoother ride, and I am sure because it ran better I got better mileage.

@GlockNinja

100% Agree with u. I use 91 Octance in all my Toyota from day 1 to 300,000 miles and sale to buy another new car. I got no problems at all about FUEL.. SUPER UNLEADED 91 run hot, more clean and car or bike or boat RAN BETTER

[thestig321]

no no expert village u lost a subber

[GlockNinja]

Why? Its good advice. When a Gas station really have 93 octane in their tanks to give to their customers, and you really get 93 octane in your car, you can tell the difference in performance from 87 octane. Might take a tank or two to clean the system but eventually you will see that the engine makes less noise and your car picks up and goes faster.

[jayguy173]

@GlockNinja it cant if you dont have higher mechanical compression or a turbo adding above atomopheric pressure into the combustion chamber

These videos are perfectly boring, but one day someone will come along and want to know about one of these subjects.

That's why these videos are so good.
