Depends on what size tires your running on the power wagon, im running 35’s and have never seen anything above 14mpg..and that’s when I’m driving like grandma.

6.4 runs 87 or 89 fine. With stock 275/70R18 tires I can squeeze 17 mpg driving it nice, most of the time though it’s around 13 or 14. Truck is fun to drive so it’s hard to stay off the loud pedal.

I only run 87 in my truck and it runs great. I'm getting about 12.5 around town. Haven't done much highway with the truck yet.

I run 89 or 93 when towing. I have never run 87, only because the Hemi calls for 89, and my 5.7’s hated 87
