Couldn't say from experience but I recall forum chatter that there is not significant fuel economy realized in the 4.6l engine. My '01 has the 4.6l and I do everything I can to keep it in the best possible running condition. Fuel consumption seems comparable to what I hear from the 5.4l guys. My guess is that conservative driving habits would have bigger impact than engine size in this instance.
Anyway, an Expedition is no vehicle to be considered if poor MPG is a deal breaker.

hell, it's underpowered in the 2wd as well. I've had cars with the same power and they still had to work pretty hard on some hills.
yes very true , but Ford has to meet the EPA guide lines for fuel eco so they make so many 4.6 2wd with a 3.31 gear

yep, that's what I've got in mine. it's a lsd too which surprised me. but I am kinda glad they did make them as I do get good mileage under mixed driving. 14.5 average so far.
My '98 will be coming out of storage soon. I will drive it 80 mile round trips, 4X a week, all highway interstate. After the initial tank of old Stabil treated gas burns out, I will clock a few fills and see if the 4.6 2WD on a steady 70mph cruise across open flat land can deliver upper teens highway MPG.

well, I wonder if a 480 mile trip from NE Ala to Jacksonville fla would yield those numbers? because that's what I'm doing tomorrow. Will post results when I fill up again. Mine is a 4.6 with new plugs wires etc and the 3.31 lsd and 4r70w.
