I'm just curious to see what you guys are getting on gas mileage with your 11th gen f150's. More specifically a 5.4L. I have a 2005 f150 5.4 triton and I'm getting around 13 mpg

I'm getting 16-17. But most of my driving is highway. If I go around town more, that drops to 14-15.

Only had mine a couple months (08 5.4 4wd) but it seems to be averaging 13mpg with mixed driving. On a road trip last weekend I averaged ~17mpg @ 70-80mph with a couple stops.

full disclaimer: I have 33x12.50x20 tires, an Edge tow tune and a lead foot. I could probably get another mpg if I really wanted to but driving like that is painful for me.

12-13 around town and 14-15 highway for me. I do have 10 ply M/Ts that are stock size. Also have a level. Everything else is stock. 103k miles CrewCab 4x4 5.4

Get about 13 around town. 15-16 on highway and long country back roads.

07 4X4 XL with the 4.6 lifted 4" on 35" mud grapplers also with an edge evolution. I average about 14-15 driving like a grandma on her way to church and about 12 MPG normally driving like a 16 year old boy that just got laid.

I've gotten 15-17 on my SCREW (60k miles) with all-highway driving. Normal is around 13. I use a Edge on Tow setting all the time (i.e. when not towing) and that made the highway number 1-2 MPG higher than pre-Edge. Can't say the Edge tune made the difference, by the way, but running the Edge Mileage Minder taught me how to use the gas pedal, which is most likely the reason for the improved mileage.

My 08 SCREW 5.4 running MPT custom tunes averages 18-19 hwy and 16-17 around town. It has done 20 on the hwy if I keep it at 70 mph and do not run ac. These number are running 89 octane street performance tune.
