3rd Gen Gas Mileage

I agree letting the engine idle, but its not great either to start the truck up, and just slam it in gear. Doesn't hurt a thing in super cold to run the truck 30 seconds, or so before taking off. The rest of your drivetrain will thank you.

 

Hence my comment something to the effect of, "Start the engine, put on your seatbelt, put it in gear, and then drive away..."

 

I have averaged 16.9 for the last 4000 miles.75% highway 25% mixed. I don't know how you guys are getting this great mileage. Doesn't matter if I'm on stock, ovt2.0 or kdmaxx pro i can't get better than 19 and that's only for short trips of 50 miles or less. Interstate 16-17, back road highways I can squeeze 18-19. been that way since new b4 changing from stock tires 265/70/16 to now 265/70/17 same same.
