Results of 9,700 Mile run on Daughters 08 2.5X. SuperTech Synthetic Oil. 25,700 Miles on vehicle. My daughter is a sales representative and puts on a lot of miles. Maybe only 30% highway which is more impressive. Obviously the Subaru had a hand in it.

Very impressive. I probably will stick with this stuff. I think this oil gets no respect.
The oil was drained cold. That obviously hurt the Flash some.
