Please post what kind of gas mileage you are getting, and if it's 2WD or 4WD and STD vs EL models.
Not Good. Just got a EL 4x4 and got about 14mpg on the highway on the way home and trending about 10 around town. I've only put 500 miles on it, so not a good indicator yet, but definitely not a positive surprise.
I have an '07 EB EL with 4X4. I have 1850 miles on it so far. Just got back from a 1200 mile trip (all highway miles) and averaged 18.6 on the highway. My in town trips are running 15.2 mpg. All miles driven so far have been in 2WD mode.
I had an '03 and an '05 Expedition before this one, neither of those would come close to my '07 EL in mpgs. With all haveing the same engine, I'm crediting the increased milage to the 6 speed transmission and maybe a little more sensible driving habits.
Gas mileage really is reflected in driving habits. I only mash the pedal when I need it. (Great engine sound, btw.) But I am averaging 16.5 mpg in mixed driving, and on a 180 mile trip I averaged 19.1 on the highway. I live in SoCal, so that includes driving through hills. When I drive on the highway, I set the cruise control at 70 mph and don't deviate from that unless traffic necessitates.
I've got an 07 EL Limited 4wd I have 5000 miles on it the best I've gotten was 20.4
@ 60 mph and about 17.9 @ 80 mph on two different trips.
City about 15.5.
Like Radcad says its all in your driving habits.
Its kind of a game with me when ever I go on a trip.
I just put in my order for a 07 E 350 XLT Van 6.0L. 5-SPD. I want to get the best mileage I can get. So the 3.55 w/out L slip, or what I ordered a 4.10 with L Slip, and the only trans option a 5-SPD AUTO. No 6 speed for vans. I won't be towing with it at all. I'm stuck, I like the LS but I think i'm about to take a hit on mileage for it. I hope i'm wrong! Should I get it?
