What octane fuel do you run?

[illuminatus]

What octane fuel do you guys run in your cars? I've notice a significant increase in engine performance and fuel economy when running 93 octane. =/

I run nothing but Sunoco 94 in my tank. I'm sure it's overkill for the measly 15# of boost I'm running, but the margin of error is there if I need it. For an N/T I don't think you'll notice a serious difference between 89 and 93. Compare the increase in performance and economy of 87 next to 89. You probably pay $.20 more for 93 per gallon, so the question to ask would be is your mileage increase enough to warrant the extra cost of 93? Another thing to pay attention to is the "brand" of gasoline. Some providers put more additives than others into the gasoline, so you're getting more crap and less actual gasoline.

93...Wont run anything less...I have bc the moron at the gas station (new jersey) put in regualr and I wasnt paying attention till after...But he heard it from me...And I did notice the difference between the prem and reg

 

[GinNBoost]

93 Octane and if I'm feeling greedy, I'll pay for the Sunoco Ultra 94.

 

[HighPsi92GST]

sunoco 94 in my 93 tsi, and used to use the same in my 92 gst.

What in the world? I thought you guys had 92 maximum.
Boy I wouldn't be able to stand having mandatory full-service pumps. That's gotta suck.
Sorry for the diversion to the topic.

91

 

[marcmsj]

go to a hardware store and buy some tolene

cheap but effective octane booster

 

[Sic95gst]

I am running 93 octane here in MD. I also use some octane booster/ fuel injector cleaner around every oil change to clean things up a bit.

 

[CrazyNikko]

I wouldnt use anything less than 92 or the highest octane rating you can get at every pump. Anything less on, a turbo model, can cause detonation (pre ignition).

 

[ShadowWulf]

91 is the best i can usually find here.
100 if im racing for extra nitrous.

 

[Catbox_95]

93 plus a bottle of octane boost/injector cleaner EVERY TIME. I just rebuilt my head with new valves, all new fuel system, injectors, etc. and I want to keep them that way!

 

[paranoidTSi]

91 octane..because no other one is available unless I drive an hour away from my house..thats pointless.

where the hell do you live?

 

[1993eclipseGS]

94 octane when i'm unemployed, 100octane when i'm employed. If I go to the track in the summer i'll have c16.

 

[trevor_shiggs]

94 Octane when I can afford to drive my car.
I fill up at Chevron

 

[Brits97TSI]

Mostly Shell's 93 V Power, then a couple times a month Sunoco's 94 Ultra

 

[Liquidus]

92 Chevron when gas is expensive, 94 Chevron when it's cheap.

 

[Turbo Talon DL]

I second Shell Vpower 93 octane Its the best i can get here usually. The track has 110 but that$ a little much. Citgo SUX Makes my car run like POO..

 

[mavisky]

93 octane on the street, 94 when i go to the track, this year I'll be playing with a mix of toulene and 94 when I go down to the track.

 

[Redmachine]

87 because it's cheap and it's what mitsubishi recommends for the n/t's

 

[2gtalonman]

110 octane cam2
