Just bumped it up to 45 psi. Max sidewall. Got the oil changed to 0W-30 full synthetic. Trying out a few hypermiling techniques as well. We will see how it does. Takes 2 days of running to get back to half a tank typically, so it will be a couple days before I see how that goes. On a bright note, at 90+ miles a night, even without a scanguage I can get pretty quick results. I've heard that the factory mileage meter is a bit optimistic, but it was pretty close on this tank.
