it depends how i'm feeling in the GTU. sometimes i get 93 sometimes 87. if i'm going racing i put 93. not like it will really make a difference. its only a dollar or two more at the pump

NOTA V6

To the contrary vosco. High octane gas may actually hurt your performance since it is more resistant to detonation.



Get the cheap stuff and be happy you have a NA rotary.

i'm probably wrong but i think i read somewhere higher octane fuel promotes cooler combustion temps ??? if so it would be better for the engine when i go drag racing cause while on the track i'm at 6000-8500 rpm most of the time and i usually do about 5 runs each time i go. just a thought :sigh:

well...like they said up a few posts... the N/A rotary does run a hell of alot better with lower rating. i run 87 all the time in my car, and i have put 92 or wutever, and it doesnt run as hard higher in the rpm range. but on a Turbo car, or even new civics and ****...higher octane is mostly better. South florida performance has a turbo civic daily driver running 11 (not sure though) and ive seen the dyno sheets on that bastard with just a difference in octane...pretty sad...it craps out with lower octane. also check out some detroits...my neighbor has a sweet 69 camaro Running on AV gas....it will not stay on with regular pump gas....



Rotaries are rotaries...
