I've been reading that there is a big difference in performance between 91 and 93 gas. Well this might be a silly question but what about 92? Alot of our premium around here is 92 octane and I was wondering if it was closer to 93 or 91 performance wise or if it was right in the middle. What would be a safe boost to run? Thanks.

 

and a forklift hahahaha i like that.. 92 is well 92.. if have tuned my car to 22 psi on 92.. but i have alot done.. you could run 22 on 92, but its not something you want to do all the time.. a quick blast here or there ok... but if your at the track, find some 94, or 102.. never hurts to go higher.. just make sure its unleaded though..

 

Thanks. I could use 93 if I wanted but I try to fill up at work (Costco) cause its alot cheaper. Just trying to find out if I'd be better off spending alittle more and use the 93 from elswhere.

 

I generally use 91 and when in Oregon I used 92.. I really can't tell a difference like I can when I use 100 or a half and half of 91/100. The boys at Vishnu state that 92 seems very much like 91 so go figure.

 

i run cheap gas if im taking it to work... otherwise dont skimp out, buy gas you know is good..

 

We got 94 around here but its like $2.3* a gallon, crazy prices. Well thats all i ever put in the evo though...like a $25 fill up....Aslong as your usuing the highest octane you have available you should be cool. If you get a dynoflash or something I would let him know the octane.

 

Can Evo Handle Fill up 103 Octane Fill up.. with out damage motor or stuff?

 

Aslong as you get a tune for it... JUst wouldnt let it sit to long in the gas tank without using it.

 

no.... very big thread on this in the beggining of the week... it will lose octane quicker though

 

^^ brb going to find thread make myself up to date

 

Um, wait, since when will 103 hurt our engines? Or are you saying no it won't?

 

You guys are lucky you have anything higher than 91. Down here in SoCal we're paying 2.30-2.40 for 91 octane, weak! That's the best we got unless you go to a shop that provides higher grade fuel. Just curious, what kind of mpg are you guys getting?
