Yep, rear tank is 18.2 gallons and the front tank is 19.0 gallons. You didn't say how many gallons you put into the individual tanks. Total miles / gallons filled = mpg.
I'm averaging 17.25 mpg; around 15 - 16 mpg during the winter. These numbers are when NOT towing my 24-foot travel trailer. That's what credit cards are for.
with that bad i would think you have a leak or a stuck injector. check your exhaust... do you have excessive black smoke or raw fuel smell?
did this just start? dont rule out someone is stealing your diesel.....
How would you know if you have a stuck injector. I wondering if I have the same problem. I dont think I have any mroe smole then normal or a raw fuel smell, but I have notice a big drop in my fuel economy. How can you check for this. I have a scanner but no buzz test capabilities. Thanks
