Gas Milage
My 2001 2500 is only getting 15mpg no matter what i do. Ive got a Edge juice w/ Attitude, its straight piped, it has a 3.55 rear end, and an AFE air intake. All the people i talk to says it should be getting around 20. Any suggestions for what might be wrong.

:humm: :humm:What trans do you have, auto or manual? Tire size? 4x4 or 2wd? Lifted or not? Any squeaks or grinding noises coming from any of the wheels, axels, brakes, bearings? Last fuel filter change?
|
4 speed auto transmission, 4x4, not lifted, 285/75R16, No squeaks or grinding coming from anywhere and just put a fass platnium 150 on about 17 months ago and they said the filter should be good for around 20,000 miles and ive only put on around 8,000.

Gas mileage???:humm::nope:
Fuel mileage :tu: The wider tires don't help. Have any problems with the IP? Is the IP stock? Clean air filter? What FP are you seeing from the FASS? |
Kinda new to this. IP? Whats the easiest way to check fuel pressure. I just cleaned the air filter not long ago but i think its time for a replacement.
|
IP-Injection Pump
Get a fuel pressure gauge to check FP. A fuel pressure gauge is a must for these trucks. :c: |
Brand new injection pump installed when the fass was put in

The truck is my sig is wearing the same size tires (studded snows, which have a lot of rolling resistance) and gets on average 17 mpg constantly (mixed driving, city / highway, empty and not towing). same ratio in the diffs as you too. I get the best mileage with the edge turned up to 5 but with a mindful right foot. Maybe check your air pressure in tires and verify you don't have dragging brakes or bad binding wheel bearings. Also, how many miles? Could be time for a valve adjustment too if you are up there in the miles.

Something is wrong. I get 14 MPG at least towing my 31' RV with me. I can usually touch 20-21 MPG with thinking to much with a empty truck.
Now remember anything creating drag will create heat. Like drag brake will make a rotor/drum hot to the touch. Transmission issues will show up in a rise of trans fluid (manual or auto). Same goes for the engine if some thing is wrong the EGT's and coolant temp will rise. Error Codes? Fuel Pressure? 285/75R16 The wider tires don't help. RV275 Injectors gave me a mild boost as well. Then on top of that I typically ran 5x5 on the Edge Comp but now I'm fighting for a smokeless tune on 5x3 but not as good as 5x5 is. http://i48.tinypic.com/mmaop3.jpg My empty run .... |
