02 7.3 fuel mileage problems

[grotey52]

I have a 2002 f250 ex cab 7.3 gettin really ****ty mileage

It has 285/75/16 tires
S&B intake
Superchip
4 inch straight from turbo MBRP exhaust

Ive replaced fuel filter and still only gettin around 13.5 average i feel it should be way better then that. The best mileage ive got is 18

Any suggestions

I'm in the same boat man.
I'm leaning towards replacing the injectors as i've read that worn injectors will kill mileage.

I just don't want to throw down the money if thats not the issue.

i get 13 in town/ 15 on the highway and have similar mods.
my dads stock 2000 psd gets 12 mpg and he only has 265 mud tires on his truck.
and he only has 89k miles too i have 226k
i call bs on some of these mileage claims lol

I agree that some peoples claims seem a little out to lunch, but i've had this truck long enough to know what it (used to be) capable of.
Over the past few years I've slowly lost about 100 miles per tank.

Check your entire drivetrain including brakes!!!

I recently have seen low fuel mileage and was gonna chaulk it up to winter fuel but a few days ago when I got out of my truck, I caught a whiff of something hot. Upon inspecting I found my pass side rear wheel was warm (warmer that the others). That caliper was frozen and seems to be fairly common. Replaced that and now I have seen 50° less egt at 65 and a lb of boost lower. Havent gotten mpgs yet from repair but I am sure it is doing better! Lol

I get 11-13 in town with a 2003 F350 stock. Highway i generally run 17-19. Had 22 on my way back from a job inland ( mostly down hill for about 30 miles). However, I dont trust the readout only because I know my last truck got 13 no mater what and doing the same driving daily, if not more, I only burn through $100 in fuel a week. My last truck did $140 a week. If you do the math being diesel is 3.95 here and gas is 3.49, I am getting better milage than what the truck is telling me.
