If I drive like ****** grandma at 65 with cruise on 23 MPG.
75 MPH I get 17.5-18. Anything over 80 and I can watch the gas needle move!

Truck in sig.
I have to convert mine to US gallons, so if done properly its best has been 19.2 MPG highway at like 50 MPH in mountains(only tested once since mods), and maybe 13.3 MPG in town. Towing has seemed to get beter recently at 10.8 doing from 65 MPH to 75 MPH and 16,000 LBS GCWR.
