New Owner of a 2007 Cobalt
I bought a 2007 Cobalt 2.2 liter five speed, last November. It's a fun car to drive but I do a lot of highway driving. The lack of cruise control is a pain but not too bad. My fault for not thinking about it. Other than that I really like it.
Put Amsoil 5W30 in which reduces the engine temp a few degrees. Plan on changing to Amsoil in the tranny if I can ever find out the spec. All the manual gives is a GM part number. GM is not where I want to go for lubricants. Any sites to recommend for this information?
