drive like there is an egg on the gas pedal....keep rpms below 2,500 the torque peak on the 4L.....let off gas and coast to stops
not WOT pedal to the floor runs....use OD, TC lockup and the tranny coast clutch as much as possible, any other gear sucks gas...
drive speed limit only
80 mph freeway with 4wdr Explorer makes the oil shieks fat and greasy rich, 15 mpg or less

or buy a Honda Insight
