You may see an increase in knock sensativity going to down to 91 octane.

 

owner's manual states for the turbo to use 91 octane or above

 

On a stock type setup you'd probably be fine. On anything modified you'd definately see a benefit in stepping up to 93 octane.

I ran 91 in my somewhat modded GST and GSX (basic mods up to fuel) only because that's all that was available around my old town, I got by just fine.

 

As long as your in tune with your car and know how she reacts you'll be fine.

 

I can tell you that here in Cali we only have 91 swill. If your car is tuned properly it will do the trick, but if I were you I'd suck it up and keep using the 93. I know I would use it if it were available here.

Well said. For a stock car 91 is OK. Heck, that is all the guys in Cali get anyway. When you start modding it will become somewhat of a limiting factor though.

 

Thanks guys. Was just wondering if 91 was "premium" enough since most premium gas around here is 93

Oh....NO..gotta rub it into those Cali. people's faces don't you?

 

can you guys in the states get 94 at the pumps as well? the sunnoco right down the street from me has it, so i get to run that all the time....but i used to be stuck with 91 octane as well so i can understand where u cali guys are coming from.

 

Sunoco in NYS Always had 87-89-91-94

Recently past 3 years they switched 87-89-91-93

Running 91 is fine in your stock DSM. My gf has a boost controller and some free mods, in her GST I make her fun the 93 its only like 3-4 cents a gallon more than the 91.

 

thats too bad about no 94.

 

At least the Unocal station around the corner from me still sells 100 octane at the pump. I haven't checked on the price in a little while though. Otherwise yeah, we're stuck with 91 out here.

 

Is there any difference in the way the octanes are measured? I come from Singapore and the only gas available there are 92, 95 and 98, and my previous Lancer Mivec back there requires 95 octane gas.

 

Sometimes I hate living in Cali....

 

100 octance pump would be awesome. i've never heard of that before though.

Yeah, the first time I saw it I thought it was a joke. Next time I'm down there I'll take a picture and post it up. It's funny too because the button to activate the pump has a hand written label on it.

 

in nj we get 94 "ultra" at sonoco to the tune of about $3.60/gallon and thats what i use because my 1g isnt daily driven so boost is always high

Is it the one on La Paz and Cabot?

 

ya 24 psi on pump gas lol.......i don't think 100 octane counts as pump gas even if it's in a pump. haha i'll start my own gas station with a flo n' go station and 114 octane just for you cali guys

 

Is there any difference in the way the octanes are measured?

Yes, there are 2 different methods.

If you can pump the gas from the pump directly to your tank, it's PUMP GAS, period. Man, If I had 100 octane pump gas nearby, make no mistake I would be running 28psi daily with no meth injection. I personally don't view meth injection numbers as "pump gas" no matter how everyone trieds to justify it.

 

Hey ten-B I dont know if you saw any of my threads but, I had a nightmare with Laguna beach chevron smogging my car. If I didnt know any better i'd say there tried to or did rip me off. bastids

 

Is it the one on La Paz and Cabot?

That's the one.

 

I said I'd post a picture so here it is. One of these days I'll have to kill my wallet and score me a tank of this stuff. Sorry the picture isn't prettier, I snapped it with my cell phone.

 

$7/gal? Ouch!
