If im broke i'll put in 93... but other than that its usually flowing the "ultra" sunoco 94 available at every sunoco in the northeast.. ONE time after i got my car i put in 89 just to try it... never do that again... ran like **** at WOT. and ran rough for a good 10 minutes after layen on it...

 

I average 3-4 tanks a week and I always use Amoco Ultimate (93) When I have the extra cash, I use the Sunoco Ultra (94). Made the mistake of running Citgo Ultimate, and felt the difference.

 

um....... how far can the stock comp retard the timing to benift from higher octane?somebody should really should put the "better gas" thing to the dyno.... see how much diff it really makes.....later
