I had a 2018 Peterbilt stinger with the mx13 Paccar w/ 13 speed that consistently got over 6mpg. The 2020 Peterbilt with an x15 and 13speed is averaging 5.6 for the first 135k miles. I almost never idle except for loading and uploading and usually just run the speed limits.

I have noticed a sizeable drop in mpg when I load trucks across the top leaving big gaps as opposed to 5 suvs.

That Paccar mx13 got 6 mpg without even trying. I bought it after a friend told me he was over 6 all of the time with a stinger. But the #### check engine lights weren't worth the extra mpg. X15 gets good enough mpg and zero problems.

Recently replaced my charge air cooler, also found that some unnamed shop had the ECM setting leave my fan on all the time. Probably done a couple months ago when I replaced my injectors. I am slightly deaf and didn’t notice it being on constantly. Gained .5mpg to 5.3 and loaded 90%. Also my dash says I get 1.2 mpg better than my calculator says I actually get.
