for those of you who daily drive your dsm's what octane of fuel do you use?
 
93 Octane ...... I used to run 86-87... bad idea it ran like shit i put 93 in and it ran like never before.
 
93 octane, my local BP has it for $2.00 a gallon, but if I fill up in WI it costs me $2.25 :confused: so much money spent in gas... :barf:

I use to put in 91 but now 89 the gas prices are so insane in SoCAL how about $2.60 for 91 octane :cry:

Holy hell!! 100 octane is only 2.79 at the pump right around the corner from my house. If gas got that high here I'd just run 100 all the time.
 
I used to run 87 in my 95 GST, it had quite a few mods!
It got better gas mileage, i got 335 miles per tank apposed to 290-300.
I drove in a mix of HW/City
Try it, if your not racing anyone or just cruising on the HW, you'll get better gas mileage!
I'm not sure why, but i think becuase the timing will adjust itself for it.
Not great for racing, but save some $$$

I currenty have been running 93 in my 99 spyder but im tempted sometimes to try it
93 is $2.49 everywhere here in Chi-Town!
 
Wouldn't using a lower octane fuel in a high reving car like ours cause alot of detenation? Burning pistons and all that fun $$$ stuff.
 
91 is all you can get around here, i use it all the time in my talon/laser . i just put some in yesterday 2.69 a gal :cry:
 
If you have a heavy modded car and running more than stock boost levels i wouldnt reccommend it. I never had a problem ever running 87. I would make sure i never really ran it hard either, but i was just driving back and forth on the xpressway.
Turbo DSM's have a knock sensor which adjusts the timimg and allows people to run 87 if they want, but you will suffer a little performance... I just use it when i know i have a highway trip or when im not gonna be racing. Saves $$
 
I run 91, that's all we have around here. I payed $2.51 the other day for it. There's a place about 10 min. away where they have 100 octane, but it's $5 a gallon.
 
OMG, and i thought i had it bad at 2.12/gallon of 93oct. that sucks....someone should ask good old arnie wtf is up!
 
94 sunoco 2 weeks ago was $1.95, I havent filled up latelty. I have been haveing tranny problems.
 
I run 89 now was running 91... payed 2.45 for 89 and its about 2.59 for 91. On track days i run 105 F&L racing fuel....used to be 4.50 now its about 6.50 damn gas prices ps if anyone in so cal wants to buy some i sell it. just hit me up.
