just wanted to make sureand im too lazy to search threads lol

 

Yes.

 

you can run midgrade tho, just wont be as quick

 

never ever ever put anything lower than 91, i personally always put 93 and nothing less, but i know sometimes people are strapped for cash and rather pay like 10 cents cheaper. But otherwise don't even bother looking at the prices of anything lower than 91.

 

The owners manual is your friend.

 

I put nothing less than 94 in my baby. Wouldn't think of doing anything else. Pricey, but worth it!

 

if you put lower grade fuel in dont hit the gas you could screw something up your car is tuned for premium

 

alrite thats good cause ive filled up 3 times already and have put premium in all the time..seems awesome so i guess its correct lol..thanx for the help

 

if you don't use premium in the supercharged cobalt you will be visited by the knocking faerie in no time.

 

Citgo 93 Works Great For Me

 

i dont know what you guys mean i put midgrade in mine all the time cuz premium is to expensive and my car runs the exact same as it does on premium when i used to use it. i have no knock and its just as fast i have slips proving it.

 

the car is designed to run best on premium but the pcm will adjust to a different grade, just less powa!
that is what we have knock sensors for

Now if you are running a aftermarket tune, then its different.

 

I wish we had 94 here all we got is 91

 

94 octane...sunoco...cant go wrong. owners manual reccomends at least 91 but absolutley nothing below 87

 

Me too... My car has never, ever had anything less than 91.
