If you use high grade gas like 89 or 93 gasoline on your vehicle is better on a 5.7 v8 engine?

(2010-05-30 10:33:18) 1. Melissa Heiland and Kenneth Says: Some people say is much better gasoline for your engine it also clean your fuel injector by using high grade gasoline it this true?

With gasoline is better Shell or Chevron?

Do you think those bottle of fuel injector cleaning work if yes witch one is the best?

Thank You!2. Mr. Dziwulski Says: use regular gasoline3. d da bomb Says: Higher octane isn't going to do anything better unless your car requires it.4. scrubbag Says: 93 gas is higher octane, but higher octane does not necessarily give you cleaner engine or is better gasoline. It is just regular gas with a higher octance rating. Octane keeps the engine from knocking which can happen if your car is a high compression engine.

But it does not add power to a car that is meant to use 85 or 87 octane. Nor does it clean better then regular, lower octane gas. It's only job is to keep down the knocking, IF you have a high compression car. Big cars, luxury cars, some high speed cars, might be high compression.

Use the gas that your manual tells you to, for your engine. (It might be labeled at your gas cap area, what octane to use.) Add 93 octane will not hurt your engine, but it will not improve your power, if your car uses 89 or 87 or even 85 octane.

Most gasolines are pretty much the same, some companies might add some additives, to say it cleans better or something, but all in all, gas is gas.

Fuel injector cleaners do work, and some good ones are STP, Techron, 3M, Chevron they are all good, and so are other brands. read this

DialM4Speed Says: If you car requires Premium or Mid-grade then use it. If it doesn't just get Regular and save you money. All gas has detergents in it and those bottled injector cleaners don't work. Well that's what a mechanic told me anyway. Tag: If you use high grade gas like 89 or 93 gasoline on your vehicle is better on a 5.7 v8 engine?
