Hey guys I'm planning to change to synthetic motor oil in a little while. I did a search on this and couldnt really find anything about brands. So I ask you, when choosing a brand, is it really just a preference??? Or are there some brands I should be careful of and stay away from??? My dad gets cases of fully synthetic Castrol from work for free. I know their a big name but do they make good synthetic oil??? Thanks...

 

preference

the threads are around... we don't need to talk about this again because it'll end up being arguements again
