What are these trucks actually getting for mpg?

Bringing this thread back to life.

With winter blend gas up here in New England, my MPG has dropped noticeably in recent weeks. I always hand calculate after fill-up and used to see 18s and even 19s regularly on extended highway runs. These days best I see is high 16s or 17s.

All motors do worse on winter blend, that's well known. Anyone know if there is any sciences to whether Turbo motors do worse than NA motors on winter blend?

Mine dropped from upper 17’s to mode 16’s due to winter blend. I read an article recently that the gov was potentially looking into just having one blend (summer) blend to help with emissions due to efficiency?

I will take one blend please. I have been warming up my truck a bit more, so I'm sure I'm losing there.

Gosh, both the 5L and 6.2L are quite a bit better!

15.6 mixed, 25 @ 45 and 20 @ 60, 17-18 at full highway speeds. Sport mode will cut all those back significantly.
