Hey Guys I have a 06 cobalt 2.2 and I was wondering how many quarts of oil I need to change my oil? Also any recommendations on which oil I should use please let me know. I have been putting the pennzoil synethic in my car but I am thinking about changing it to either castrol or royal purple. Thanks guys for any info that you all can give me.

 

5 quarts of the cheapest conventional you can find.

 

5 quarts. Cheap ass conventional oil will be fine for your car if you dont plan on keeping it over 150,000 miles.
