time to trade it in for a cummins?

[loudtruckguy]

Ok My first power stroke was a 1996 f250 no mods at all. Still have with 255XXX runs great but it was a 2 wheel drive extend cab....so i bought an 02 f250 crew 4x4. First off i love both of these trucks but the 02 is my favorite by far. Here is the issue the 02 is terrible on mpg. Did napa diy airfilter, edge tuner(i know they suck) tightend up all my boots and put on 4" exhaust staight pipes. My mpg is the same 50/50 highway city i get 12.5 solo....towing i get 10.5 (8K)......the towing miles i'm ok with its the solos i have an issue with. the mods gave me way more power but no mpgs. I'm thinking about tradeding to a newer v10.....gas is cheaper and my 02 is worth what a v10 06 goes for..........i work with some cumm heads and they are getting low 20's solo and high teens towing.

Both my 99 and 02 get about 17mpg empty right now. Don't know why yours is getting such low mpg

Do not get a v10 gas sucker. You will regret it, they get horrible fuel mileage.

I'm not a fan of how the V10's sound, I'm now hooked on diesel, but you stil can't beat the sound of a Pushrod V8.

try getting custom tunes? what size tires and gears do you have?

[ridiculously_necessary]

x2 on custom tunes. be sure your injector o-rings are good?

i like cummins, just not the engine crate they come in. i too would stay away from a gasser, JMHO

gassers are worse....use to get 10mpg hwy or city....was brutal

[ridiculously_necessary]

i had an 02 6.0 gasser, about 9 city and 14 hiway unloaded. i didnt have the guts to check loaded, but was guessing about 8mpg with 8k to 9k on the hitch.

Sounds like you either have 4:10s or some performance issue.

I have 3.73s and I am averaging 17.Xmpg... last 2 fill ups (Always to the neck) were 17.16 and 18.17.

I would look at the condition of the injectors and their o-rings as said above before giving up on it. It's possible you have a bad injector and/or o-ring, another thing to check is the fuel bowl and the rest of the fuel system to ensure there are no leaks.
