Soooooo, on stock oil I was getting right at 11.9 MPG. Swapped to royal purple a few weeks ago, ran 3 tanks of gas, and it jumped to 13.2 MPG all 3 tanks. Same driving, nothing else done to the truck, and these calculations are all done on paper, not the evic. Anyone else experience the same? I'm simply stunned. Can't frigggin wait for a tuner!!!
