Fuel?

DaRockwilder · 11-14-2006, 10:43 PM

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!

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. =/
