I mostly city drive and get 12-13 tops in town.
Long highway rides I’ll eclipse 19-20 in eco.

I have an xlt not the digital cluster so you might have done it already and its different for me. I found this video for you, its done at about the 2:20 minute mark.

4X4 Reg. Cab 8’ bed with tow mirrors and 3.73 rear, only getting around 14mpg around town but it’s been getting better as the miles go up. I still have less than 700 miles on the truck and any highway driving has been in the city where the traffic is either silly fast or stop/go.

On this thread, people have been getting really good mpg from the 5.0:

I have a Platinum 4x2, which automatically gets me better mpg than most others which are 4x4. Truck has 4500 miles on it now. Over the last 2400 miles, I have averaged 24mpg, hand calculated. This includes a couple of long trips on the interstate at 70mph, with some 65mph when required. My usage involves very little city traffic. 3.15 gear, with a tonneau cover which might also help mpg at speed. Regular fuel.

Everyone is getting better than mine.

SuperCab, 8’ box, 4x4, 275/60-18 tires. 2500 mi
Mileage has steadily been creeping up
One trip meter I have not reset and lifetime is now reading 20.0
Trip two is reset at fill up and last tank showed 21.5.
Meter is a bit optimistic as calculated I got 20.7.
I’m rural, so little to no city traffic, but about half of the trips are under 50mph and the other half at 80.
Always in normal mode, and the auto on/off is shut off.
I’m pretty content.
Just had the oil changed.
Was still at the full mark and the guy said it still looked new.
Will change it again at 5k and then every 5k after.

Bed cover makes a BIG difference. That bed back there is like pulling a parachute.

I'm getting exactly same mpg as I was. From day one.
Has no effect on mine nor any I've had in the past.
In fact my 2003 sport track got better mileage when I put the very same cover on.Sill have it..
It's less wind drag with cover.

The tonneau cover as an improvement to mileage is one that has been tested empirically, despite that; tonneau manufacturers and retailers still pull ridiculous numbers out of their ass because consumer protection laws are barely enforced these days. Just look at all the snake oil being sold by the supplement industry.

Any anecdotal evidence of better mpg can likely be attributed to the many other variables being faced when driving.

The subject of aerodynamics is very complex and sometimes counterintuitive. There’s many examples of early attempts to improve aerodynamic performance of the automobile that wound up being worse than a brick and several early streamlined cars have a lower coefficient of drag in reverse!

I don't care if it improves gas mileage

I don't want my bed getting flooded with rain water with my Decked system back there. Plus it just looks good (in my opinion).

I didn't buy a Full Size truck to get good gas mileage. It would be "nice" but that's not why I bought it.

5.0, Fx4, 3.31, hard tonneau, regular gas, mostly Eco mode, 50/50 split of city/highway driving, easy acceleration/stopping, leaving A.S.S. on (I think I'm one of the very few who really doesn't mind it), higher side on tire pressure: Averaging about 18.5-18.9 mpg.

Took a 400 mile highway roundtrip going between 55-65 the entire time, and my trip average was 22.7.

If what you are after is top end MPG then being aware of your driving style and adjusting accordingly is crucial. Weather conditions can also play a monumental role. All it takes is a couple of lead-foot starts at intersections and a slight headwind and your average MGP goes straight to hell.

On the other hand as @UNIKRN150 said, that's not why we buy these.
