Doesn't anyone actually look at the Owner's Manual anymore?

Has anybody ever?

My old camry seemed to knock with 87, but I think it needed a tune-up real bad or something. Got 35mpg pretty easily though.

I run the cheapest 87 octane gas I can find in my ES. It hasn't skipped a beat in the 43K miles that i've owned it. Anything higher is just a waste especially with the recent gas prices.

If anyone is curious about how the mileage is affected by the octane... Check this out...

I only run 87 now, and my driving style is a little more agressive than it used to be... The car runs absolutely perfect.

Your welcome.

It's sort of weird, I am almost O.C.D. like when it comes to my car... but with everything else, I am pretty laid back... strange stuff.

You ought to see my maintenance log book, it would be too much typing to make a web-page with that thing.

the only cars you need to run 91 octane or above are older cars with well over 100,000 miles on it just to keep the car performing properly. Our car are brand new and advanced in technology that using the minimun octane will guarantee great performance

good good good... from now on I can save about $2~5 bucks.
