Fuel Mileage

[mfdboy911]

Hi im looking for someone who has a similar truck set up as myself to tell me what there fuel mileage is. 2000 F-350 7.3, Crew cab, long bed, 4X4, 2inch lift kit with 32 inch tires and a stock Engine. Reason i ask is because i recently tested my truck for fuel mileage and i ended up getting 13.5MPG (mostly freeway driving). Is this too low? Or average?

Forgot to mention i have 3.73 gears.

It depends on how you're driving on the highway. If you're doing 80-85, then it sounds about right. If you're doing 65, then it's way low.

Thanks for the response I usually set the cruise control at around 78mph.

Welp, there's your problem. Slow it down to 2000 RPM/70ish MPH (depends on tire size). If I do 72MPH/2000 RPM, I average 17-18 MPG. If I bump it up to 75 MPH, it goes down to 15.

Well you are driving at California freeway speeds (see open season) , plus So Cal traffic is...well you know. My truck with taller gears like yours gets really good mileage on the open road at about 65 with the cruise on.
