Poor MPG
I have a 2016 cummins. I was averaging about 16.5-17.0 MPG city until November when I changed my fuel filters & the weather turned a little cooler. Now I'm around 13.0. I am thinking I made a mistake on one of my filters or got the wrong one. I am pretty sure I got the correct ones but who knows. Help.

Winner winner chicken dinner!
As the big man above said if your in an area with winter diesel your mileage will drop. I notice about a 2mpg drop every fall/winter, it's been that way since my first diesel truck in 04/05.
Area, DRW or single, rear end ratio, trans will all effect it but 2-3 mpg drop seems the norm.

Thanks
I live in the Boise area. Normally our winters are fairly mild. This year we've only topped freezing a couple times in over 2 months. We're calling it snowmagedan. Anyway, I had a powerstroke before the Ram & didn't see a drop in the winter so this big of a drop surprised me. Thanks again. Russ
