Best mod for increasing MPG??
I just recently bought a 2008 f250 for one of my landscaping crews. It is a 4x2 supercab with the 5.4L engine and 4.10 gears. Every single day it is used to haul a 14' dual axle landscape trailer, with all of the related equipment including a commercial riding lawnmower and 4-6 guys. So far it has about a thousand miles on it and is averaging 10.8 with mixed highway and street driving. I hope it will increase slightly when it gets some more miles on it, but would still like to squeeze every ounce of fuel economy I can out of it. What is the SINGLE best mod I can do to increase the MPG? remember, this is a work truck, please dont suggest thousands of dollars in fancy mods, thanks.

Other than that, you could change the gearing to a lower ratio like 3.55, install lighter tires and wheels, install underdrive pullies, run higher air pressure in your tires.
I'm not really sure what you were hoping to hear. You are pushing a very heavy truck around with an engine that is better suited for the lighter F150. Hope this helps.

The 5.4 is way too small for a SD, and especially when you are pulling trailers every day. Any mod you make IMO will not provide any tangible results, take a close look at the numbers as to where the results kick in for many of those mods, and more often than not it is in higher RPM ranges....and given you're not worried about things like EGT etc. for a diesel....I'd pocket the cost of any mods and put it towards gas

The only free modification that might help is bumping up the tire pressures, but only if you are only running them at pressure specified on the door jamb, or if you only check them visually and have no idea what they really are (which means they are probably too low).

To the OP, there isn't much you'll be able to do. You've got a small motor pulling a big load every day. Just be happy that you're in double digits.

In the back of my mind, I was thinking that nothing that he could do would be worth the cost, but that's not what he asked for. Try to be helpful, not hateful.

Going to 3.55s would make the engine work harder while loaded, decreasing the gas mileage. If he was cruising the highway all day long unloaded, then yes, 3.55s would be the way to go.
Have a great weekend guys...I am on beer number three right now.
Freeky out!
