On the high end you would average 10 mpg more than what ever you have now. I really think that’s on the high end. Diesel is 50 cents higher than regular here. That calculates to about 4 years or 60,000 miles for the average per year mileage to break even. The first manufacturer to come up with a reliable 1/2 ton diesel will get the resale up tick the bigger pickups get will win big time.
