If you're going by the display you need to do a few hand calculated tanks an compare them. I have mine calibrated to being pretty much right on now. It was up to 1.5 mpg optimistic before I adjusted it.New 2021 model 4x4 Average 20.2. It only has 100 miles so far
Good thing Costco is still at $2.84 for 91 but at this rate I'll be back to running 87 soon.

Hello Langley,I think most of the complaints are because many of us aren't getting close to the EPA ratings on the window sticker. I drive it easy most of the time an sneak some quick acceleration runs in an I'm happy with 20 overall in the winter an 22 in the summer which is around what I get.
