what octane do you run at the track?

[MustangEater8251]

I have heard so many mixed reviews about ictane levels I notice no serious differences, actually wed. night I mixed 1 gallon of 110 octane(I was worrried I might run out of gas mid-race) with less th4en a gallon of 87 octane, and still did not notice much.

I have heard higher octane burns cleaner, but lower octane gives mroe power, in out cars in relative stock form.

What do you guys think on the subject?

i run 93 pump gas because of the ADS.

If you have autotap and you find 87 knocks, use 89, then 93... I doubt you'll see a performance increase on 93.

I've so far only run 87 at the track, no chip mods, and I'm doing quite well [img]smile.gif[/img]

i only use 87. In the manual, it says suggested octane to use is 87..heck, they made the cars. They know whats best for em..but than again its GM .. no problems ith 87..i think it runs better than 89 or 91 IMO..

Well manual also is to say what gives best mileage and so on.

Interesting fact a teacher of mine should me, he said never get mid range gas, its cheapr to buy half lowest, half highest, you get a higher octane then if you just had mid-range gas, and its cheaper.

Also I have heard of people frying o2 sensors and CATS on super high octane. Well it does smell nice [img]smile.gif[/img] .
