Anyone use premium gasoline?

If the owner's manual does not specify that the car REQUIRES anything over 87 octane, then don't use anything above 87 octane.

'nuff said.

Some higher-end vehicles can only use premium ( like some Lexus's and Acura's), because they are designed for it. But any notion that premium gas will make an engine designed for 87 gas "run better" is simply psychological. ONLY use 87 octane! Don't waste your hard-earned money.

Hey Paul I'm with you and going to throw a comment here on this ancient thread. I have noticed myself that even though premium is more expensive I do notice an increase of mpg. Typically my automatic gets 30 mpg with 87 octane. When I run 93 octane it increase to 33 mpg. I have done this several times just to make sure this wasnt a fluke.
