The higher the octane, the better. Therefore any octane higher than regular, which is 87, will be better. Even some good ol' racing gas.
This is a common misconception when it comes to gas. The higher the octane, the more additives to make the gas burn slower. This prevents preignition in high compression engines. Look in your owners manual, if it says to use 87 octane like a Mustang GT, then you will only waiste your money putting higher octane in your tank. Higher octane fuel does not burn cleaner and it does not prolong engine life. This is only true if you are running stock of course. If you turbo or s/c your engine, then you will need to burn higher octane fuel to get a more complete burn with a slower burning fuel.
Really? I had been lead to believe that premium was "cleaner" and better on a cars motor. Well I know it applies to dirtbikes and ATVs because their engines are so sensitive to everything, especially 2 strokes. Your supposed to replace the top end on a 2 stroke almost yearly, thats how fast they wear out. The pistons and such. Don't take care of them and they will seize up on you. I know a guy who runs a methenol mixture with his Banshee and it's hella fast, but he takes great care of it and doesn't run regular 87 through it, ever. It is highly reccomended to use high octane for offroad vehicles.
So running premium in a vehicle that normally runs on regular has absolutely no effect at all?[/quote]
nope. its just a waste of money. it wont do anything to help with performance. now unless you run FI and bump up the timing and someother things you got to run an higher octane. but with the gas prices the way they are you may see people putting regualr in there MB, BMW, lexus and other vehichles that require premium gas. and thats stupid.
