Makes sense. I about to do my next oil change in a couple of weeks and I wanted to use MC 5000 5w-30 again, but I think that I'm going to go with Valvoline ML 5w-30. The mileage on my car is in the signature. I'm going to switch from supetech oil filters to advanced total grip since it's made my purolator.
