I drive like a old man also on the hwy, normally around 100-105 km and the lie-o-meter says 27-29 mpg but hand calc. i get 22-24 mpg. i NEVER tow anything so. __________________ 2008 Cummins 3500 SRW Laramie - Flow Pro SS 5" TBE, Black Maxx w/OD, EGR MIA, H&S Fuel Rail Plug, S&B Intake, SS Steering Box Brace, N-Fab Front Light Bar w/ 4x Hella 500FF Driving Lights...
