Truck in sig with tune. I get total 15.6 combined. I have 1 50 minute commute (each way - 4 days/week). Do my share of off-road every weekend during hunting season as well. A tune will help a lot. The dealer won't.

Look at mine. 45mph is my sweet spot. Lol.

Winter blend gas isn't an issue in the south. It is the summer gas that is formulated to produce less emissions. We get better fuel mileage in the winter.

I have a rcsb 5.0 4X4 lowered 3".60mile round trip to work 5 days a week I am getting 10L per 100km or 25.6 miles per US gallon. Also runs 14.81 in the 1/4 with 91 octane in the tank

I've got a 2012 FX4 with a 6" Lift, 20x12's, and 35's. With the 5 Star Tunes I get anywhere between 12 in town and 18 on the highway with the 87 Performance tune.

All summer gas produces less emissions. Winter gas has butane which lowers mpg.

Yeah....I really doubt that.

I'd give anything if my '13 Limited got close to that! 15.1 is my best ever!!!

It was averaging about 17 combined when it was stock. Not sure how some people are getting 22mpgs. Never seen that in the life of the truck. Tire size has not been corrected for, next time I fill up I'll calculate it by hand and see what it is

I'd kill for that.
