Fuel?

[DaRockwilder]

Hi!

I just bought a 2003 Alero with a 2.2 Litre Ecotec. Can anyone tell me if I should be running regular or premium? The owners manual is missing. I know the motor has 10:1 compression, which pretty much, to me, means I should be running premium.

Thanks for anything!

regular will be just fine

go with the 89 grade..... it seems to be the best for me.... (2.4L)

Run regular in my 2.2 and no problems here...

OK, thanks all for the input!

Unless you start doing some modding just use regular.

i have considered putting higher grade fuel in mine especially now that its over the 100k mark, but its unecessary anyways. regular fuel unless u dont mind paying more. =/

I just filled up with 91 Octane. We'll see how it does!
