3.0L Ranger fuel mileage questions

[red2003xlt]

2006 3.0 2WD auto, standard cab with long box. <65 MPH highway with an empty bed the best I ever did was 21 MPG. Mileage difference between 3.0 and 4.0L is quite thin.

I have the same truck a 2003 model. Do a complete tuneup and check if your fuel injectors aren't leaking. I get 24 on the hwy with cruise control set at 70.

My 99' with 220k miles averages 21-23mpg hwy without trying. 19-20mpg mixed driving. Truck will cruise at 80mph no problem, no need to downshift on hills unless towing or hauling. 3.73's, 5spd and 245/70-16's

I've gotten as good as 20.2mpg hwy on E-85. Love that stuff, wish I could get more of it around here.

I'm constantly at 20mpg, '99 3.0 4x4 w/3.73 axles and 5-speed manual.

When we drove cross country, some of the fuel in rural areas gave us as high as 24mpg.
