GEN 2 GEN2 MPG thread...

A cool 14.4 on 93.

17.9 with 1600 miles on her.

16.2 average at 4300 miles. See 17 to 17.5 on the freeway running 75 - 80.

For those hand calculating, is the difference between that and the truck readout the usual 2.5% less than the truck calculation ? That is what I have consistently calculated on my 15' and curious if it will be the same fro my 18' Raptor.

Just rolled 10k miles, mixed highway / city / towing life time average of 17.1

I just cracked 10k miles. Mileage just keeps getting better now that it's summer, the last few tanks where I'm doing about 20 % city and 80 % highway (I set cruise to 70 mph) I am getting 18-19 mpg on the overhead and hand calculated it around 18 mpg. A lot of times I'll have 500 lb in the bed as well. For fuel, I've been running mostly 91 octane in the summer, 87 or 89 in the winter.

With a truck this tall and wide along with fat tires, speed and air temperature/density make a bigger difference than a standard half ton and their deep air dams and pizza cutter tires. If you are bucking a headwind, going 80+ mph, or it's very cold out, mileage drops in a hurry. The nice thing is you can choose mileage when you want or have that 450 hp for fun and burn some dead dinosaurs.

And just as a side note, the truck hasn't missed a beat in 10k miles. So far so good, but I bought bumper to bumper 120k mile warranty just in case.

17.4 - 19.3 mpg.

How are you guys getting such good mileage? lol.

On stock wheels, I was getting 14-15 mpg on 91.

Just filled her up after I changed my wheels to rotiforms and tires to Mud Grapplers 20x12.5x20 and i get 12.5 mpg now.

Anyone else notice slightly better MPG on 87 than on 91/93?

On back roads driving like a grandpa I can get over 20 MPGs. During normal driving which is mostly back roads and includes a fair amount of WOT playing around I regularly get 14-15 MPGs.

I just upgraded my exhaust to a Borla ATAK, curious to see if that affects anything.
