I'm getting 18-20 mpg (u.s. gal) average with mostly city driving and some county road driving. Considering it's winter, & I'm doing probably 70% city on that figure, I'm pretty happy with that. Before it turned cold, a hunting trip 3 + hours away I scored just shy of 29 mpg round trip hand calculated. Just a couple weeks ago I drove 2.5 hours away and round trip was right around 26 mpg.

To answer your question though, there are several threads on here that will probably directly give you some answers. Feel free to search, but I will throw out some basic information for you. Things such as winter blend diesel, cold temps, drive line fluids being thicker when it's cold, snow on the roads equates more rolling resistance, warm up time is fuel being burnt without miles driven which equates to bad mileage, etc.

These things would all make sense. I am curious if your mpg was always this low or if it changed recently. That could tell you if it is due to the winter temperatures or not.

It's crazy how many things factor into our mileage, fortunately we can control a good portion of it all if getting the best possible range is one of the main aims.

I see you are a jr. member as well. But something to be aware of that a lot of people are not on the forum is you need to reach your desired speed and 'lift' your foot off the accelerator for a second to force the truck into 7th or 8th depending on your speed. Unfortunately our trucks seem to like to hold the higher torque gears and this will drastically eat in to your mpg. Just a change of driving habit you have to make with this truck if you are not already.

This is a trick I think really helped me the last time I was driving my truck. I found at 60km I could quickly lift my foot then apply pressure to the accelerator and it would allow to shift up, however I am speeding when I do it lol. however as soon as my wife starts driving the EVIC AVG fuel consumption climbs very quickly. In her words "I like it when I step on it and it pushes me into the seat!" She also drives my 2012 charger like that lol

Bad mileage

I have a 4x4 tradesman club cab, no frills. I got 30. 5 on the highway before my catalytic converter crapped out over the summer. Ram then installed a new catalytic converter and flashed the computer with new fuel parameters. Mileage went to ****, only 26 on the highway and once the cool temps came I only got in the low 20s. They look at me cross eyed at the dealership when I show,the dealer my fuelly graphs and stuff. I FEEL YOUR PAIN!!!!

I mean that is out of the ordinary. I think that it makes sense that a part would be malfunctioning because if everything is working properly your MPG should be better.

Do you believe that all your parts are working properly and its just the temperature that is the problem?
