Does anyone know where to buy this? I'd like to give it a shot in my TransAm and Outback since they see a bit more severe service but I can't find it anywhere I looked (wallyworld, Autozone, Pepboys) I emailed Valvoline but figured I'd see if anyone here has seen it out and around. If not, the regular maxlife is a synth blend which I'm sure would be just fine also.
