Searching the EPA fuel economy standards after noticing the 23-25 6.2 window stickers showed only 18 mpg highway, discovered the EPA rated the 2019 6.2 at 22 mpg highway and the newer ones at 18 mpg highway. Anyone know why as the new ones are supposed to have more cyls on afm and start/stop on some models?
