I was wondering what kind of oil do you guys prefer. ive always used valvoline in my vehicles. im usind the Valvoline durablend oil in my truck and my cougar i seem to like it but i want the best oil for my car for a good reasonable price, ive always heard that the mobil synthetic oil is the best. what do you guys prefer synthetic or convenventional, and what brand. i know oil is kind of a personal opinion but what do you guys prefer.........
