What do you guys think? I work for Cummins and can get this stuff at work for dirt cheap. I called Valvoline and a lab tech told me this stuff was loaded with moly. No numbers to back it up though. Thinking about running it in my '03 5.4 triton. What do you think? Going to stick with 3-5k oil changes. Also, is it the higher the pumpability number, the easier it flows cold? Thanks!
