At that rate I think it will be cheaper to keep my 460 in the long run.
I've had a few Cummings diesels. A 93, 00, 07. They were powerful and got better mileage than my 460, but they never got consistently 20 mpg. Average was about 16 around town and 18-20 on the freeway depending on how fast I was driving. The fuel savings doesn't offset the purchase price and maintenance costs.

My '97 F250HD gets 12-ish on the freeway if I set the speed control at 65 and keep my feet away from the gas and brake. That's empty or full to the top of the bed with camping gear.

Around town, stop and go traffic, it's single digits, baby. 9-ish, give or take a 1/2 mpg.

Oh well . . .

20-25MPG is over exaggerated, I'd say 15-18 at the most. There are some aftermarket things that can be done to help the engine run cooler. The hotter the engine, the more gas it consumes along with losing horsepower. LMC truck sells an underhood heat shield that helps absorb heat under the hood resulting is cooler temps. Another thing to do is aftermarket exhaust. The factory exhaust system restricts backflow which also causes a decrease in fuel mileage.

Ha ha ha ha ha..

Fuel efficient 460....
Just forget about high teens and be happy with double digits.
If I saw 13 on the regular I'd be so happy I'd pi$$ myself.

for the poster above.
"Heat IS horsepower" go see who said that...
Adding an insulating blanket is not going to 'help your engine run cooler'
Back pressure IS an exhaust restriction. So one is not creating the other.

To contribute tho it's of no help.
I have a 90 f150 5.8 with e4od.
With it loaded with 600LBs and healthy tires I got 18-20 on the top half of the tank until I ran into this no start and tranny bs. Thanks to my idiot *** and abuse.

Doubling the mileage in a 460

If you search the site for,"fuel economy ford 460", in the resulting list there is a thread,"don't laugh...." Look at my post from today 7/12/17. I get an honest 16.5 at 65mph in an 84 F250. My post will tell you exactly what I did.

My 92 4x4 extra cab gets an honest 10mpg and that's after the engine rebuild. I've done the diesel thing which was a very expensive lesson with a 06 dodge Cummins. It was by far the most expensive vehicle I've ever operated over a five yr period due to fuel related issues. With the amount we spent on bad injectors and high pressure pumps which failed due to bad fuel according to dodge I can drive my 460 the rest of my life. Best of all no payments and I can repair most of the truck.

What you did to your truck may have gotten you better gas mileage, but these are ninth generation trucks. 1987 was the only year for a carbureted 460. 1988 and newer 460's are all fuel injected. A fuel injected 460 wouldn't even run with those modifications.
