What are you guys getting for milage? The more I drive this truck the worse it seems to get. Just filled up, drove about 50 miles on the interstate with the cruise set at 75 and I averaging 9.1 mpg. 17' 350 Platinum with 3.55 4x4. Stock height. Swapped to 295/65/20 and added a Retrax cover.

I wasnt expecting great great milage but this is much worse than I was hoping to get

 

probably caught the beginning or middle of a regen. I'm getting 14-15 at 65 2k rpms

I'm getting about the same. Agreed on the regen, if you see your MPG on your trip meter taking a hit (especially if you're recently reset it), you're likely in a regen.

 

I understand the regen. But to keep dropping for 50 miles? My 16 and 12 both dropped as far as I stand and was usually over pretty quick. Just not so much on this one. We'll see how it goes these next few days

 

There's no doubt that the regen strategy is different for these 2017's. My 2011 would start and finish a regen in about 10-15 miles. I've watched the regen on this 2017 go for 30 miles and the DPF soot load percentage drops much more slowly. On the other hand, the DPF seems to fill up more slowly as well. The net difference may be zero but it sure is different.

 

My regens are 45 min plus watching the instant fuel consumption.

 

Mbovinet, I have the same exact truck as you. You were in a regen. I had the same experience last week, cruise set on 74, 9.7mpg. Same trip this week, I
got 14 mpg. At 65mph, I get 15.5mpg. At 50mph, I can get 18-19mpg.

 

Another thing with the regen is that it is a bigger hit to mileage. Instant mileage used to drop to 12 mpg and now it's 10.5ish. Not a fan but resigned to its greater good to society.

 

So far first 300 miles i did a 62 miles interstate trek reset the trip at 65 I averaged 17mpg
