Past weekend took drive to Fab Fords show at Irwindale Raceway. Figured i would check long distance driving on a full load of fuel.
On way to CA from AZ ran into very heavy headwinds 75-80 mph and mpg suffered. Including 135 mi in California site seeing more stop n go traffic got 19.5 mpg. That run was 505 miles. On way home thought it may be close on fuel so slowed speed down to 65 mph. Bit of side/tail wind but was rewarded with 24.8 mpg!
On the one fill went to ca drove around then return trip to az. 859 miles on 39 gallons.
Who would have thought a tuned Raptor 3.5 would get that great mileage especially wiTh overall steep gearing.
