I just bought a 2001 camaro SS, ls1. Im not sure what to use after the auto-rx treatment.... Im looking for max protection and cleanliness....but thinking maybe I dont need syn? I can get mobil 1 0w-40 and chevron supreme 5w-30 supreme for basically free... but would i be better off with a HDEO? 15w-40 for summer or whatever, but what is a cheap easy available HDEO available for cold starts down to 0 degrees F? maybe, delo 15-40 for summer, and i was thinking 10w-30 for winter, but figured it might not be the best for real cold starts....
