fuel milage

[kelti819]

is there anyone with the 01 cc 4x4 7.3l longbed running 285/75/r16 getting decent fuel milage with minimal mods, im getting around 12mpg, was getting close to 20mpg then just dropped for no reason.....any help or info would be great.

check your fuel filters, make sure all of your intake boots are tight. Clean air filter. Another way to get better mileage is switching all of your fluids to synthetic. I gained 2 mpg's in my 2000 F250 stick, and my dad gained 2 mpg's in his 2003 6.0 auto.

my filters are good, oil is good, just dropped all of a sudden and cant figure out why, i put the 4 inch exhaust on and milage went to s***

Ya its pretty simple to start with, There are rubber boots with clamps between your intake, intake tubes, intercooler inlets, turbo to intake, intake Y pipe to the intake runners. they all have hose clamps that keep everything sealed so you don't lose boost. Go through and make sure everything is still tight. Its simple and free. Good place to start.
