What octane level do you use a GM Stage 1 kit?
Ok either none of you have ever actually owned a SS/TC or you are all just talking out of your asses 
The SS/TC, stock off the showroom floor said you can run regular, but premium was RECOMMENDED. It even said so in the manual and on the fuel door. I'm almost positive that the dealer had regular in mine when I bought it, but I've ran premium since day 1. Many others on here said the same thing. With the GMS1 kit, premium became REQUIRED. In the kit, a new sticker was included to cover the old one on the fuel door. Unfortunately for me, the dealer that put my kit on stuck the new sticker under the hood with the other engine info stickers
. GMS1 is setup for 91 octane, but of course 93 will only help.

I sometimes fill with regular when I know Im going to dump a whole tank in one long highway trip. Our gas here is preemo and I dont notice ANY issue or decreased fuel mileage... that said %95 of the gas that has gone into my car is 93.
The e10(up to %10 ethanol?)/94 **** seems to run like junk with GMS1.

LOL @ all this debate about whether you should use premium or not. You bought a turbo'ed car -- why wouldn't you use premium? That's like taking a smokin hot girl home from the bar and getting just a handjob when you could have banged her out.
Ok so my next question to you guys: do you understand what octane does? All it does is increase gasoline's resistance to detonation. You can run regular in any car, even if it requires premium, as long as you don't push the car hard enough to the point where it needs that additional octane. If you are going on a long road trip, where you aren't going to be getting into the throttle much at all, and you aren't going to be lugging the engine, I see no issue in running regular instead of premium. I have a very hard time not getting into the throttle so I will always be running premium.
Also, some of you must be very lucky to live in areas where they don't rape you for premium. Here, the cheapest premium I can find is $0.30 more than regular, but if you go to a Shell or Mobile station, you can expect to pay $0.50 more than regular. It's insanity, and these premium price rapings only just started to happen in the past like 2 or 3 years.

Please.
I think I'm going to call up the dealer I bought it from on Monday morning to see what they used to fill it up with. Probably going to us premium either way. Also not sure if you know this or not but in PA there is a tint law of 75%, will someone still inspect your car if it's like 20%?

^Ha, best post of the whole thread. Don't worry, your AFR needs to be about 2 when running this, but I'm sure the car will correct for it with the fuel trims.
The rest of you keyboard warrior idiots need to lay off the stupid juice. Please return to your fast food jobs, as you know nothing about engine design or the thermodynamic processes behind a running engine. You're all worried about detonation? How many of you are custom tuned? I'd be more worried about detionation being custom tuned by random guy A after seeing how many engines are either blown up or get torn down only to find horrific evidence of prolonged detonation on this site.
OP, just use premium. It's required with any tune other than stock, and even then I'd still just run premium. /thread

1. If you NEVER plan on going more than 25% throttle then you *MIGHT* be able to get away with running less than 91 octane gas in a GM stage 1 cobalt.
2. Even at low load the cobalt ss turbos with gm stage 1 (and even the non staged ones) get quite a bit of knock. For that reason alone I would NEVER run less than 91 octane.

I can't believe this question is even asked anymore....
