I use Valvoline Durablend too. My mechanic advised me to use this oil (it's actually the only oil he keeps in his shop). At first, I wasn't really convinced but he told me that it's actually really good, so I was like what the hell, at least its not that expensive, plus it can't be that bad. Well, I guess it turned out he was right about it being good. /ubbthreads/images/graemlins/smile.gif
