Default Lifted ecoboost mileage

Hey I'm just curious if anyone out there has a lift and tires on their ecoboost and what kind of mileage they are getting?i have a six inch lift and 35x12.50x18 nitto terra grapplers and I can't get better than 12 mpg. I understand I'm not going to get 30mpg with my set up so save the comments but talking to a salesman at another dealership he's sold some with the same setup and claims they are getting 20mpg easily.

I'm glad you posted this. I also have a 2012 fx4 SCrew and am considering the same mods. Can't wait to see some replies.

Nobody is getting 20MPG in an EC running a 6" lift, that is a lie. I run all my mods (see signature) and get about 15-16MPG - I was getting 22MPG stock.

If you consider the sheer weight increase of the tires, the resistance on the vehicle when lifted...that 20MPG comment makes zero sense.

I think it comes down to your gearing. If you put 35's on an ecoboost with the 3.31 or 3.55 gears, its going to use about as much fuel and time as a boeing to get moving. If you have the 3.73 or 4.10's you should be doing a little better than 12mpg (granted its not secret lifts/bigger tires = sadness for mpg's and power) Most of the people I've talked to getting 16+ with their eco's and lifts have at least the 3.73's and keep their foot out of it..

You are really going to believe a salesman??

Your mileage seems about right with that set up. You could try and search the 100's of threads on this topic.

I basically leveled out my front(which took 3" on my truck), and although my friggen SCT programmer can't accurately correct my speedo for the tires, I'm getting progressively worse mileage than I was stock(I'm in the low 12's). I'm running 33.4" tall tires, but where I think I'm doing the damage is with their 12.3" width and 10-ply(E) weight-SEVENTY TWO FARGING POUNDS EACH. Next time 'round I'm looking for C or D rated tires, and 11-11.5" wide MAX.
Problem I've found is with an 18" wheel(the size I like), you have A LOT of E-rated tires, and very few C or D's. Especially in anything taller than a 32.
As far as the professional bull-****ter claiming '20mpg easy' with 35's, you shoulda asked for a minute to put on your waders before he told you that.

Can anyone throw this in to L/100km. Mine has a 2.5 inch level kit with 34.4 in trail grapplers and I can't get better than 21L/100km I have ordered exhaust hoping that little power boost might help turn the tires easier and am looking in to intake and possible tuner. Please help I'm only getting 625km per tank with 7700km on the truck
