93, 92, or 91, whichever of the three is the highest sold in your state.

use 93! i put 89 on my ws6 cuz thats all they had and i was running on fumes and it started sputtering for the first few miles and then it was normal again and my check engine light came on.

diesel....makes her run like a champ! But seriously, I run 93 all the time, except for back when it was $4.30 a gallon, then I ran 89 and kept my foot out of it.

I've ran 87 for as long as I've owned this car.
No problems, I get on it without any problems. Run 87 when I go to the strip too.

In order you should use 93,92,91. But if you can, try to always use 93. but nothing under 91.

91 at the minimum, 93 is best

computer has high/low octane tables, car will run considerably better using 93! but it wont kill it to use 89... i only use 93 though, its 20 cents more a gallon, only a few bucks more per fill up, like 2 or 3 dollars, dont feel like doing the math.... but in the end its better for it and will thank you in the end!

doesnt really matter, 91+ will give you your best mileage, but a stock ls1 will run on 89 or 87 fine, it will just retard the timing and not give you as much performance/mpg

youll get better mpg's on 93 octance than 89 or 91, so in the end it equals out. dont be a cheap ***, always 93

Run what the car needs. I ran 89 in mine never heard the slightest knock, so I stayed with it. My wife had a 97 Z28 and it needed super to run without spark knock. There is no sense running more octane than the engine needs, it won't get you better miliage unless the fuel you were using was causing spark knock and the PCM was pulling timming.

ALSO...The PCM does not have high and low octane timming tables. Low octane fuel will cause spark knock which will cause the PCM to pull timming. PERIOD. It does howver have different tables for when the engine is in limp mode.

Anyone ever run something like a 101 to see what happens or a 98 or 97 octane? Really curious as to how the car would respond.
