F250, 6.7L Unloaded Mileage

[harmanrk]

Looking for information. I know my current trailer in no way requires either a 250, or Diesel, but we are looking to replace the tow vehicle, and considering that we will upgrade the trailer in a few years to a fifth wheel, and trying to plan ahead.

I know mileage will be bad when towing (real world numbers, not the legendary figures some spout on the internet), but what kind of numbers are people actually getting highway and combined when not loaded? Looking for people actual experience with the 2017s or 2018s.

Thanks

I find just the opposite. The newer the truck and the more advanced the emissions hardware is, the crappier the fuel mileage becomes.

I know it's a 'pie in the sky' statement but my venerable 97 F350 7.3 returns 21 empty and 17-18 loaded everyday, winter and summer though it rarely gets driven in the winter.

New, Tier 4 final trucks don't get close to that mileage.

My 2015 gets 17 mpg when traveling with about 75% highway and 25% city. When commuting in 50% city and highway it gets around 15 mpg. I get around 12 mpg towing my fifth wheel plus or minus 1 depending on wind. I'm sure the 2017s get just a bit better.

Mine is a 2012. But it is the 6.7. My daily driving is about 25% hwy and 75% city and the mileage runs between 15.1 and 15.5. Unloaded highway running 65-70 the mileage will run 19-21 depending on wind, terrain, and traffic and if I keep my foot out of it and maintain a steady speed. Don't know if the newer ones do any better or not.

Tugging the 35' high profile 5er along at 65-70 the mileage runs 9.5-10.5 depending on same conditions above.

I don't have a ford, but the modern diesels all get similar mileage. Town unloaded they get 12-15. Highway 17-21. Loaded with a small trailer like mine I get 13 on trips. I don't drive slow.
Those numbers depend alot on driving, tire size, gearing choice, summer/winter diesel.
