As the summer season is in full swing, I got to wondering if there should be more of a driving method change when the Outside Air Temperature (OAT) is high?
I currently drive 55 mph on the highways. Should I reduce that to 50 mph to help offset the reduction in horsepower due to a narrower temperature difference as well as possible inevitabilities such as air conditioner use?
