Originally posted by Johnny: I'll take a stab at this from my old Pennzoil marketing days. The Mobil 1 T&SUV was originally destined for the diesel pick up market, but since it said T&SUV on it a lot of folks were using it in their good old gasoline trucks. I sure GM and others complained some since they recommend 5W30 in the gas motors. So now they have a T&SUV 5W30 and the M1 Turbo Diesel 5W40 for the diesels and the dihards that want to use it in gas engines. Bottom line, they did not do away with the beloved T&SUV 5W40 they just changed the name. Bottom line, bottom line, it's marketing, marketing, marketing.
