i was in autozone tonite and bought a VC oil filter for G5 and clerk said i should at least buy a stp but i have seen ac delco, supertech fram, bosch, purolator, STP and they all seem the same to me and i ended buying the VC which looked identical to others i have bought...any comments on VC filters would be welcome, i dont think there is any difference between them and the others i mentioned...i dont think clerk knew what he was talking about...a mobil one filter would be better but i use synthetic oil anyways with usually 6k-6.5k oci
