91?

 

93, with 106k miles you gotta

 

Never below 92 for detonation's sake.

 

Whatever the highest octane the pump has. Depends on the gas station and what they have... 92, 93, or 94.

 

where do you guys get 93+? The highest i can find is 91.

 

93 octane here

 

93 From BP/Amoco

 

Sunoco has 94. They have 4-5 other octane choices too. I can't really remember what any other stations have.

 

93!!! $26 to fill up

 

i use 91 octane and use Nos race formula octane booster every time i fill up

 

I used to run 94 on the street and 100octane unleaded at the track. I have to admit that last year I usually ran 100octane on the street, as I want to have the option of turning on the nitrous anytime without worrying about it. I can get it at the pump, but it's $3.50/gallon

Next year I am going to run C16 or C17 at the track (and use O2 sims) and will continue with 94 or 100 unleaded on the street.
