But I do love ridiculous fuel mileage claims. Good entertainment!
on that note, gassers have come a long way. I attribute the more recent gains to cylinder deactivation. Comparatively in 3/4 tons had 2 - 6.2 Fords in recent years that couldn't get 15mpg if you towed them somewhere, no 4cyl mode on them. 2011 5.0 F150 that was a bit better, with the OE puny bald tires would get 15-17mpg if driving miss daisy. 2016 5.3 Silvy I have now gets 18-19mpg driving slow on the highway (under 75ish). BUT upsize tires one size with an AT tread and it knocks 1-2mpg off.
