I log and calculate every tank. In my truck, I switched from Castrol start-up 5w-30 to GC 0w-30. The mileage has been consistent and the same.

I noticed no change in mileage in my wife's Civic when I went from Mobil 1 Trisynthetic to Royal Purple 5w30 to GC 0w30. All three oils showed identical MPG numbers. She only gets about 23 MPG (city driving, combined with her lead foot)
