Bed fully loading with camping gear heading through the blue ridge mountains I was getting 17.8 in my 5.0

 

Just checked my fuelly report. I had a fillup on Jan 24th that averaged 22.5l/100km (10.5 mpg).

'11 Eco SCrew 3.73's. I remember that tank too, I burned something like 20 liters just idling on remote start (you can tell b/c the in-dash fuel spent doesn't advance when it is remote started). It was pretty cold outside, and I'm really not a big fan of cold.
My drive to work is only 3km, but the max speed is 50km/hr, and there is 4 stop signs and all residential roads. I really don't get good mileage to work and back. Gotta take it out on the highway every couple weeks and feed some throttle to it to clear it out.

Love my truck. Just got 33" tires on it too, I'm guessing that's not gonna help my mileage, hahaha.

 

I dont feel so bad now. I'm getting avg of 14.2 in my Raptor with 50/50 driving.

 

tire size might be helpful in this thread too..

 

Wow I get 14.3 in my XLT

 

Average of 13.7, last tank was 14.4 so I think we're off of winter blend gas. LT275/65R18 tires

 

my worst so far, unloaded, was 12.6.

that was all city driving and not having any concern for gas mileage.

truck is a 2011 ecoboost fx4 with 305/55/20 mud terrains

 

lowest ever for me was 17.8 mpg - all city driving and rush hour traffic, lots of heavy footedness and idling.

5.0 / 3.31 / 4x2

 

About same for me towing the boat across Florida to start the vacation. Gotta say I didn't care one bit and enjoyed the looks we got when passing people easily with the boat attached and bed loaded.

 

9.6 mpg on my tank from 1/15/12 to 1/28/12. Drove 282 miles and put in 29.32 gallons. Everyday was a daily commute of 7.5 miles each way (8 stoplights), and pretty much nothing more. It's not fun being outside when it is -50F.

Truck was stock, and unloaded. P265/70/R17 tires, 4x4 (did not use 4wd), and 3.73 gears with the 5.0.

Do I win?
