Al Powell extolled the virtues of synth oils. OK, you've got me sold. Now my question.. Is one flavor of synthetic the same as the next? Would an off brand (ie not Mobil-1) be just as good? IMHO one from "Pep boys" should be as good if it meets the API specs, right? Just wonderin' BTW, Red Ur-Q seen on Pearl St in Boulder this weekend.. if you're a lister.. nice car! /J. 80Q
