Hi, i'm new to this topic so please be fair to me =). This may be seem like a very old,old discussion but i'm a beginner. I just bought a new 06 truck. I'm planning to use 5w30 dino oils for my break-in period and then switch to synthetic after 3,000 miles.
I would like to know how would some of you rate the dino oils? (like havoline, castrol, valvoline, pennzoil etc.) Many of you seem to me rate the havoline higher than the rest. Is there a scientific study or testing that has been done on dino oils?
Another question is regarding the GF-3 or GF-4, what does this mean on a bottle? Does GF-4 have more additives than GF-3?
Is "starburst" the exact same word as the API certification mark?
Thanks for all the replies. Hopefully this will be a stepping stone into the new car world for me.
