Exxon Superflo is about the same product as mobil 5k if you are looking for UOA results. Good oils, just not the flavor of the month. I plan to run some superflo in my new truck for the first oil change as I get through break in. Basicly ExxonMobil makes "Genuine" oils for Toyota, Honda, Dodge and probably more than that. The Toyota oils at my dealer have the tell tell wide mouth bottles.
