Just filled up today. Previous tank was all city driving. Got 13.5 mpg for that tank. 3.5EB, Screw, 4x4, 3:55 gears. I don't have all that heavy of a foot either.

 

I can't seem to get my mpg to drop below 15.4 in the city......on a 6.2L. My best city tank was 18.3. EB lovers can chew on that for a while.

 

12.1 Lifetime average (3000 miles) Ecoboost 4x4 screw 3.73. This is mostly around town in flat Florida. I drive slow with a stock empty truck. Like the truck but the mileage is VERY disappointing.

 

09 screw 5.4, 3.73's
2.5" as 35" trail grapplers
13 mpg around town
went to Galveston last weekend and got 13 on the highway
Not hand calculated went by display

 

I am pleased with my Ecoboost except for the mileage. I think Ford needs to stop advertising that it has the power of an 8 and the fuel economy of a 6.

It should say it has the power of an 8 and drinks like an 8 !

(Before everybody starts beating up on me, I know..... I didn't buy a full size 4x4 PU for good mpg.... I know)

 

That's funny.

 

Im getting 11.4 city empty (never going over 30 mph) on my 1 week old (189 mi) Ecoboost F 150 xlt 3.55 gears. I know its early but I dont see myself jumping for joy over gas mileage

 

I got 0.0 mpg when I reset my computer and set at idle for a bit....

 

2011 5.0 Screw, Bone stock 14.3 driving around town.

 

2012 6.2L 4x4 373 Platinum 13 around town
