Topic: fuel mileage with a Ford F350 diesel

Posted By: tenacioushunter on 07/27/12 09:34am

What can I expect for fuel mileage on a Ford F350 diesel towing a 14,000 pound trailer?

Thanks,

JT

What year and engine generation?
Rough guess...between 8 and 12.

I'm getting 10.5-12 with my 6.0 towing around 11.5k at 65 or less.

With the truck/trailer combo in my sig -

Best 12
Worst 8

A lot depends on type of terrain, weather, driving habits ...

I'm averaging 10.5-11.5 but it can dip as low as 9 with headwinds and climbs. That's based on about 5000 miles on our current trip.

Depends on what engine/yr.... I tow with 2012 F350 6.7..... Our Big Horn Loaded and weighed on CAT scale is 14,000 lbs. Towing from Florida to Texas to Oklahoma, Missouri, illinois, Indiana - so far we are just under 12 MPG when towing..... Our overall MPG, which includes driving un-hitched is 14.3 MPG... Total of 3500 towing miles (I keep a log) and total combined (hitched & un-hitched) miles tracked = 7350

I might add.... When on interstate our best MPG is 55 MPH, but I usually tow at 62-65 MPH..... Usually at 55 MPH on two-lane hwy... Also, If you're in hills you're gonna do less.

Your mileage is going to depend a great deal on the terrain and the speed at which you drive. 5th Wheels in particular have a huge amount of frontal area and the wind resistance increases with the square of your speed. At 60mph the wind resistance is four times what it is at 30mph and you need to add in the speed of any headwinds.

I worry more about range with my truck and if you are getting 8 MPG then it is worth considering a larger after market fuel tank.

I've talked to several that pulled up to Colorado from Texas. I live in the Texas Panhandle and the wind usually blows, and of course usually righ on the side. This year it hit on the side so I figured soon as I hit Raton it would be behind me. No still strong sides on the side. Talked to a couple of other Ford truck drivers, and we all got bad mileage. 8 to 9. One was F250 one F350 and a F450 pulling 20000 lbs. Lots of varibles so really hard to tell what you might get.

I have a 2012 F-350 heavy Duty crew cab 2wd dually, pulling 16500 5th wheel Montana, 39.6 feet, Pin weight 5500. On regular roads I run say 60 to 65 and average 11-12. One long section in Indiana I got 14, I ask is wow this would be nice. In mountains I get 9.5 10 MPG. I have switched to 5-40 Rotella Symantec I will watch mpg. Just hoping. I only have 15500 mileage at this point. Running empty I get here in Durango CO 18-19.

So far, I seem to be averaging between 10 and 11MPG with the rig in my signature. I haven't hit 6000 miles on my truck, yet, and keep hoping that it will improve as she breaks in.

2011 F350 duallie towing a 13'6" x 41 ft toy hauler that scaled at 18,275 lb. Best ever was flat, no wind @ 62 mph leading to 10.0 mpg. Worst was about 7 mpg in the mountains. Typical is the mid to upper 8's. For me, the wind is almost as big a factor as the hills.

I have the same truck and at 55 I get around 12.5 mpg towing. At 60 I get around 11. At 65 I get around 10 mpg. So the numbers really go down with speed. With the 4:10 rear at 62 the tach is right on 2000 rpm. So I would guess with lower gears 3:73 you might get better mpg at a higher mph. It's amazing how the mpg goes down so fast in a few mph...

2000 F350 Dually 4 door long box. 36 Foot Cardinal 5th wheel. Total loaded weight 21,480. Last trip was just over 7000 miles. Averaged 13.8. High 20.something and low 6.something towing at 60 mph.
