With the rise of fuel prices I predominately use 89 octane and switch to 91-93 about twice a week. Keep in mind most of my driving is done on the hiway with no noticeable loss of power or any other problems. I drive 134 miles round trip each day. My DIC says average speed 51 mph and 27.6 mpg.
You definately must use premium fuel for the stage upgrades which is why I have not put a stage kit in yet. Fuel prices will continue to rise throughout the next fuel weeks for fear of a spring fuel shortage (particularly on the west coast), refinery maintenance, and oil is trading over $61 a barrel.

i don't even look at gas prices anymore... i don't get why some people do, and would even go out of their way to save 3 cents a gallon on gas, but waste that 3 cents driving the extra mile to get there... people bitch and complain about it, but really, it's 2 dollars...
yea, that extra 2 dollars a week is a killer

why would you want to risk damage to your engine for the sake of a buck or 2?
if your so desparate to save 1 or 2 dollars a week on gas....why the **** did you fork out the probably 50-100 more your paying on your payment every month to get the 2.4 or 2.0L engine?
what the **** kind of backwards logic is that?

I run 93 octane usually, but when i make trips (like when I travel home from school on breaks, like I am tomorrow) I fill with mid-grade 89 since I do not need the added power, but I do not want to run 87 octane and screw with my timing too much. Takes a tank to get back to normal timing.

Well, I run 87... if you guys don't like it, too bad...
It's funny how everyone jumps and says that it hurts your engine....
It's also funny how the Tech2 says that I've never had a knock sensor go off either....
Hmmm... and I drive it in -30C weather too.... I'm really killing it...
Besides... I don't think I own a fast car,so I don't drive it like a race car.... It's my winter car... plain and simple!
I won't bother arguing with anyone, I work at a fuels research center (see below link), and should probably know what is going to hurt my car.... but hey... everyone is an expert on here!

I dont know about you, but that doesnt sound good to me.
And it sure as hell doesnt sound like something worth saving $2 a week for.
Like i said. Why would you spend possibly hundreds of dollars more a month to get a 2.4 or 2.0L supercharged vehicle....and then try to save $8 a month on gas and reduce your HP, and risk damage to your engine.
doesnt make any sense.

Therefore, 87 octane doesn't hurt a stock Cobalt SS-SC... cause if it was going to knock, it would have in the -30C, dead cold winter...
But I'm done with the subject from here... It's pointless trying to argue the point.... everyone seems to be an expert about it, and I obviously know nothing!

You do realise that the quote I wrote there was directly from GM right?
How the hell would I know personally. I dont run low octane fuel in my car.
Im just pointing out the fact that GM says 87 octane will cause spark knock....
but all of it is moot. until someone answers for me why they can justify the cost of an ss or ss/sc every month over the far cheaper, more fuel economic, and *happily runs on 87 octane" 2.2L cobalt*
but take the risk to save $2 every fillup.

Who cares really I run 91 and have since day one thats the best fuel we got here. we can argue this point to death and it would prove nothing. As for affording it I bought the car cause I liked it its not my main mode of transportation I have other vehicles and I don't even drive it in the winter. I do agree with you that premium is better for it but if he is running reg with no problem good for him

Dude... we drive Cobalts.... not super cars....
Cobalt = economy car
I hate to break this to everyone... but a Cobalt (SC or not) is not a high class sports car... deal with it!
And just to justify 87 octane for you.... my SC is my daily driver.... the grocery getter....
If I want speed, I have an R1...
If I want class, I'll drive my '72...
