I know there are several on here that swear by Amsoil products. I had the good fortune of meeting the South Carolina regional distribution manager today at Harbor Freight. He was asking me about the VX, turns out he used to sell Isuzus when he was younger, and we got to talking about trannys and whatnot. I saw the Amsoil rig in the lot, nice truck and trailer and I mentioned I would like to talk to that guy, he said "lucky you, thats me". I was thinking of switching all fluids in my VX to Amsoil, but for you amsoil users, do you do the once a year only change for engine oil?
As for you mobil one finatics, it got some of the lowest ratings for breakdown and scar testing. Just thought you should know, it is still good stuff, for there is much better out there...Let the flaming begin.
