^ThisYou won't be happy with this answer. Conventional or synthetic.... doesn't matter much what you run if you do your oil changes religously. Spending a bunch more on something like royal purple is just flushin the money away.
I run rp in the rear and will be puttin some rp in the tranny when the time comes. As far as engine goes I run ro or castrol syntech with K&n oil filter. Just whatever u do don't use penzoil or the other cheaper brands. Just stick with Mobil1, castrol or rp. Oil brands do make a difference as do filter brands. Don't do fram oil filters.
Ugh, you had to say that. My brother works at an NTB so whenever he does any work on my car if im do for an oil change ill have him do it. Of course they use Pennsoil filter and oil, i thought it was ok cause they tend to be a "well" known brand, time to do some research
