Whats the best 93 octane brand to run in a GSR on track day: Chevron,Shell,Exxon,BP,Sunoko?.

I just curious cause im trying to make sure my car is running as best as it can for a upcoming track meet, and I also plan on runnin a little octance boost to.

 

octane boost is crap and you dont need the extra octane in your car unless you're going to raise boost or swap to a heavier jet. gsr's require 91 octane and thats the stuff you should run.

as for a good brand of gas, they're all the same gas. seriously, theres pipe lines that deliever petroleum products all over north america, the companies put 1 barrel in 1 side and a barral comes out the other, its not the same barrel. its just the same quality. each different brand adds there own additives. i personally trust mobile, shell, and bp. as for the cheaper stations (red apple and other no namers) i dont like to buy gas there.

remember, your car requires 91 and the only reason to run higher is if you have a reason to.

 

hmm i will keep that in mind

Well said! I agree.

 

ive been putting 89 in my GS-R but it really requires 91? i remember when a couple times that i did actually put 91 in my car just hate it right up. (91 is like 2.25 a gallon....can you say GOD DAMN)

ummm u need 91 my friend...and no i cannot say god damn to that price since its so high. that is like the price we are paying for regular = 87octane here.that is consider cheap already for 2.25......

 

i use either shell, 76, or chevron gas and on 92 octane. i follow orders from my car and it orders me to use premium unleaded only

 

my cluster doesnt say PREMIUM UNLEADED FUEL ONLY, lol. its a LS, did a swap with a GS-R. does that octane booster **** really work

 

well dont some, cheap gas company's have a higher water content in there gas? even at higher octane too.

the thing you have to watch out for is the additives. a lot of the cheaper companies use additives to increase the octane rating, but it's really crappy gas

 

actually its not the water you should worry about, but the other additives. water is there to displace so they can have more total liquid to sell. the other additives that they put in are kinda crazy. there are quite a few detergents and an additive to keep the volatility down in summer and volatility up in winter, to keep it from freezing, theres additives to absorb and isolate water in the fuel system. most of these additives are different alcohol's. alcohol has a tendancy to raise octane and absorb water when in gasoline, but if theres too much (like the octane boosters add) it actually does harm to the fittings, lines and you filter. i dont suggest adding any additive regardless of what it is.

i dont trust seafoam and all that other garbage. if you can get it at advanced at it claims to be some "mechanic in a can" then its probably garbage and your better off just fixin the problem then trying to mask it with one of these products

You might want to stop putting 87, 89 or the reg. stuff in...i used to do that with my prelude (vtec) for about a year and a half....my rings were trashed...lost compression and f*cked up every thing internally! Just my experience

your lucky, gas around san diego for 87 is 2.23-2.40 and thats 87. out premium 91 is around 2.50, so we're the ones that have to say god damn, not you. why doesn't cali offer 93 octane ? whats the reason for different octane levels in different states?

actully it went up already. its like 2:30+ for a gallon of regular also. remember, its at least 10cents more in san franisco. god, everything cost too much in the bay area...

 

i agree with everything 3.504 has said so far.....and i always use 93 octane mobile, never had any lower octane in her..... and my compression is purrrrfect

 

I say keep using 87 or 89 octane in your GSR your car will thank you latter by knocking

 

I only trust Sunoco in my car....they have some pretty badass racing gases, and it might be my imagintation but my car runs so well with it .....

 

91 chevron
