I am looking at a new F150 Supercrew Lariat 4x4, 5.4L engine, 3.73 rear end, 4 speed auto, the window sticker says 13/17 mpg, what are you owners actually seeing?
Thanks for your inputs.

 

I'm averaging low to mid 14s local driving. Recently took a trip with mostly open highway driving and averaged 17.5.

 

13-14 city only at about 35 mph
16-17 mpg mixed
18+ highway...gotten 20+ on longer highway trips

 

i'm getting 16(lowest yet) to 20(loaded with quad in bed, boat in tow) canadian gallons. terrible happy with the truck.

 

My '08 has 500 miles on it; filled up yesterday and am getting 15.7 mpg overall. I am more than pleased as I anticipate it will only improve in the future. 5.4 V-8, auto, 3.73 rear.

 

Ditto-What Tylus said

 

These years are pretty good on gas or decent depending on how heavy your foot is dont know the mileage on the parents 06 but its pretty darn good for a big heavy truck in the stop and go city its a Supercrew 5.4l 3.73

 

My window sticker said 17 and 24 on an 08 Scab XLT with the 3.73 and the 4-speed auto.
I'm getting on average 17.8 mpg (I do 80%highway driving everyday) and on a long road trip through the mountains with a few pit stops and an overnighter driving through the city I got 19.26mpg.

I've leveled off at about 17.5mpg, so it isn't too bad.
