Ford 350 mile per gallon

Two things that will really hurt fuel economy are speed and head winds. We have a 2012 F350 CC DRW towing a 19,000 LB 5er. We typically get 9 MPG running 65 MPH on typical flatland roads. With a strong head wind, we will drop to 7 to 8 MPG. With a good tail wind, we can hit 10 MPG. If we run up to 70 MPH, we will drop ONE MPG overall.

So, if you are not happy with your fuel economy at 70 or 75 MPG, slow down. It is the same result as a head wind to drive faster.
