  1. Which Oil to Use???

    New Member Introductions
    Hey guys. I'm a new member and I just purchased a 2007 Cobalt w/110000 miles. I don't know what oil the previous owner used (synthetic,semi synthetic or regular oil). Which oil would you recommend for my 07 Cobalt LS. Oh and would you do any other maintanance also since you would be unaware...
