Hi everyone,
looking to get some input...Can anyone tell me why my fuel mileage is down into the 6mpg? Thats what its saying on my dash, although im sure its fairly accurate because Im not getting anywhere near as far as before on a tank of fuel. Truck is serviced regularly. Thank you
Not sure the exact temperature, but its going up on the gauge like it normally does. I installed a coolant filter kit a couple months back. The low mpg was happening before I installed it.
I shoulda asked if you have any electronic diagnostic tools to work with. we need to see some numbers. There are a lot of possibilities but I suspect injector issues. FICM (Fuel Injection Control Module) voltages is where I'd start.

First I'd manually check your mileage to be sure the gauge is correct.
Next, you really need some engine data as suggested.
Is your turbo spooling up? Any loss of power? Rough at startup? Last time you changed your fuel filters?
We need to see info with koeo and engine running? What's your Baro, ebp psi, MAP, etc. EGR?
Lots to evaluate on these engines.
Obviously speed and towing have some affect but 6 mpg is ridiculous.
