I'm hoping we will get more than 13 mpg with only freeway driving. My truck is 4x4 so there is a little more rotating mass.
I drove pretty much all 4.6 and 5.4 Fords, new trucks, for the entire run of that engine platform. I’d run them 30-40k mi per year and get a new one every year or 2. Buncha 1/2 tons 2wd and 4wd and a few 3/4 tons 2wd and 4wd.
13mpg was a good round number for a 1/2 ton 2 wheeler. Don’t think I ever saw that in a 4x4 except doing downhill. V10s about the same. Had a couple of those too. 10-12mpg not towing mostly highway.
The Coyote and 6.2 were a small improvement in mpg and a big improvement in power, partly due to the 6speed.
