    lol- but seriously, thats not right. If you look in your owners manual, it will tell you what kind of fuel is required. My Civic lx did not prescribe premium, my Prelude S did not require premium, but my Prelude Si did. And my S2000 does too.
    If you put a lower grade of fuel than what is recommended, you will have premature detonation and running issues. Just like if your car does not require premium, it will avail you nothing to step it up to premium. Of course, the car will run, but not with the power, smoothness, or efficiency originally intended.

    read your owner's manual... give it what it says... putting non premium in most non premenium cars probably wouldn't be too bad, as the computer will compensate... and vice versa, I don't think putting in premium in a non premium car will net you any major gains assuming it's relatively stock.
    Please tell me if you think my car looks good. But don't tell me if you think it's ugly - only on IA

    all about comp ratios and cylinder pressure.

    93 burns slower and reduces likely hood of detination and preignition

    to those that are stupid, those are 2 different things.

    my SI requires premium, so why risk it to save $2.50 at the pump?

    No- we are saying the same thing. I should have quoted 1439/2000- I was responding to that in the response in which you quoted me.
