Is it okay if I run 93 octane fuel in my 02 oz? Also will it matter if it mixes with a little bit of the current standard gas in my car? Tapatalk oh yes
Ehh...not really. The most noticeable things will be a smoother idle and the engine may run a little quieter
It really depends. The 4G94 was only has 2 fuel maps. 87 and 89 octane. To run 91 or 93 octane would be no real difference. I run 89 all the time only because its not the cheap barely filtered crap and not the expensive stuff that wont make a difference in anything for the engine. It really depends on the tune that in your car for it to make a difference.
