Question for everyone!

Just wondering what octane level all of you use in your car? I sometimes use 93 or 94, even though the engine only says 87.

89-93

89 most the time, 93 if i take it to the track.

higher octane numbers means resistance to burning.
the longer it can go without burning, the better spark advance/timing advance you can get. however, if you're just putting around town, you're going to get an incomplete burn with 92+ octane, killing gas mileage.

heck, in the winter when the track is closed, i even put 87 in [img]tongue.gif[/img]

Higher octane is not more powerful, it just burns slower by design. If you have detonation on low octane (as the result of high compression, major power-adder, very advanced timing) then the high octane is good to cure that. If not, then all you get is a less powerful stroke due to the slower burn... :(

No need to spend more per gallon to go slower.

Unless you have experienced KR (knock retard) or have mods that would warrant an increased octane level you are wasting your money buying the more expensive gas.

ive been putting 91 for about a year, but now listening to you all I think I will go down to 87.

Three factors come into play answering this q:
1: is my Jet chip on (not right now b/c of #2)
2: Am I poor this week?
3: Will my wife help me out with #2

I usually run 89-92

93 octane

[camaroincal]

Well, I'm pretty sure the guys that wrote out Camaro manual know what they are talking about. They say 87... ;)

There are so many mixed opinions. I just split it right down the middle with 89
not too good, not too bad :D
