M1 5w-40 New name? The new 5w-40 from M1 is called Turbo Deisel Truck. Is it the same as the old 5w40 Truck/SUV. I can't find german castrol or the royal purple racing oil locally, so I decided to get this oil.

Same stuff different name. They switched the T@SUV to 5W-30 and it is the new heavy duty formula. The M1 5W-40 is the best bang for buck oil out there for the LS1's.
