i have been using Mobil 1 in all of my cars and trucks for the past five years and always believed it is some of the best motor oil out there. I read a lot around the Oil test board and have seen mixed emotions on the new SS formulation. Even compared to the TriSyn formulation. What is your opinion of the Mobil 1 SuperSyn?? Other than M1, I could also see using AMSOIL which is not that much more money and seems to test consistently better.
