Ford Super Duty (1999-2016) :: 2014 F250 - Fuel Mileage While Towing
My 2014 f250 4x4 crew cab with 6.2l gasser only gets about 7.5-8 mpg at 65 mph while pulling my 27' bumper pull travel trailer. I know that thing is basically a wall trapping the air but is there anything I can do to gain a couple mpg more? I can average about 15 mpg at 65 mph without the trailer on the highway.

I've changed my knock sensor, my o2 sensor, fuel filter, air filter, alternator, and cut out my cat. Still can't figure out why my truck has no power?

I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!

I have owned a 2003 v10 triton f-250 now for 8 years and when I first got the rig I was getting 11.5 mpg mixed driving. As the years and miles went on the mileage got worse and worse and now I'm lucky to get 4.5 mpg.
View 14 RepliesFord Super Duty (1999-2016) :: F250 - No Power To Fuel Pump Relay
1999 f-250 super duty... okay, here is what i have going on. basically no power to the fuel pump. For the last 2 weeks the fuel pump relay and 1 of the relays behind the radio (next to the blue relay) would chatter and the truck would die. Wait about 5 minutes and turn the key on and if the chatter was gone then it would fire up and run... So NOW no chatter on either relay and not cranking up. - motor turns over just fine- just no power to fuel pump. So I changed out the relay- both behind the radio and the one under the hood. still chatters and no start. i have checked the Inertia switch and 12 volts there... Here is my question, when i turn the ignition on, i have no power to the base of the Fuel Pump Relay.... Where does the power come from to power the relay???

6.4 diesel 2008 F250.... I have been having lots of trouble with low power and sputtering of this diesel truck . It almost seems like a fuel filter but I changed them out 2 times now and the same thing keeps happening . It has been a very cold winter here and if there was any water - it would freeze.
If I am going down the highway and it starts to sputter. I put transmission into neutral and shut motor off with key. Start it up and it's good for less than a minute or two and it's back to sputtering.

2012 F-250 super cab 4x4, 6.7 and just over 100k on the odometer. He pulls a 20' landscaping trailer with about 3000lbs of gear on a daily basis. He drives the same rounds weekly and the truck is dealer serviced. His trips to the pump used to be every 7 days and are now occurring every 3-4 days. He's down to 10.4 mpg. I usually can pull better mileage with the 6.2 pulling said trailer.

My 2011 F350 is shaking like a wet dog, all the time, loaded with a trailer and empty. It's the whole truck, not just the front end or rear end. It'll shake a Dr Pepper flat in 10 mins. No one can figure out why. Maybe y'all can think of something.
Here's what we've done
New tires, balanced
Alignment
Replaced ball joints and sway bar
Replaced carrier bearing
Replaced passenger front hub that got mysteriously locked and henceforth destroyed.
Replaced all 4 shocks
Where to look next?? Guess I should mention is 4x4 dually with 177,803 miles.

View 7 RepliesFord Super Duty (1999-2016) :: 2005 F250 Seemingly Not Getting Fuel
2005 F-250, Diesel, 105K miles, all stock, fuel and oil filters changed in May, about 4000 miles ago.
three times in the last 4 days the truck has seemingly run out of fuel. Got a full tank about a week ago, at the same place I always go, so I doubt it is bad fuel. It ran thru a 1/4 tank with no problems.
4 days ago, it wouldn't start. It just didn't seem like it was getting fuel. It sat for several hours and then ran fine for about 15 minutes and then slowly died out. It wouldn't restart. It sat for 8 hours, and then started again, ran for about 15 minutes and I cut it off.
The next day, it started fine, I drove it 3 miles, cut it off, and an hour later it started but ran for only 10 -15 seconds and it slowly died out just like I was running out of fuel.
I started it this morning and it fired up right away. I let it idle in the driveway for 30 minutes, and it ran fine. I cut it off, went to start it 30 seconds later and it won't fire again.
The backyard mechanic I use for simple stuff wants to replace fuel filters and see what happens. BTW - twice when it wouldn't start, he hooked up his computer and it had no error codes. You can hear the fuel pump running when you turn the key on and the mechanic said he could feel the pump working when he put his hand on it.
Should I let him do that or is there something else we should be looking at?
Ford Super Duty (1999-2016) :: F250 V10 - Fuel Gauge Not Working
1999 F250 V10 gas. I changed out the fuel pump, and now the gauge doesn't work. Checked all fuses - they're good. Is there any possibility that I could have accidentally pinned the float under the pickup sock, or got it hung somewhere? Is this a common occurrence? Don't really want to drop the tank again - but looks like I will have to in order to check/fix.....
