How much mpg drop with 4.5 inch lift???

I'm considering the 4.5 inch lift and running 35s on my 2011 F250. I'm new to lifts and hearing that the mpgs could drop anywhere from 2-6mpg, can anyone tell me if that's about right or true? I'm new to lifts and just trying to decide if that is true.

Thanks

Tough question to ask. No one can provide a definitive answer. Yes mpg will go down whilst your truck and tire size goes up. How much ? Who knows. My 08 was poopy on fuel as it was then with the 6" lift and the 36x15.50x20 MTZ's it was noticeably lower . As for the 6.7l maybe someone with a similar lift will chime in. (Albertastroker ?) round about guess? 2mpg, there's seems to always be alot of he said she said, when it comes to mpg talk so......And alot of people are recording different as stock . Which is normal due to variances in ambient conditions

Thanks and I was thinking around 2mpg's especially if I stay with 35's and don't go up to 37s but I'll see if some others chime in with their own numbers.

I'm getting anything from the 12's to low 14's or 13's on average at 70-72 MPH. AMEC Electric (Andy) is recording similar times with his 4.5" with 37's. I have 35's on mine (see Siggy). I also have just under 14k miles and am running 60psi in the tires. My MPG's seem to be more in the 14 range this past week. -Steve

Yay I get to chime in again haha. 16.6 mpg as a high. And 14.1 as a low. Usually all highway traveling at 100-110km/h. I was nearing 20mpg stock height with 35s. Running 37s with a 6" lift and Torq 2 now.

Matty I think you should buy me a Mini maxx haha :p
