3500 SRW. 18.3 on the way home from the dealer.

I sure hope my 19 gets better with time. I have 600 miles on it and it doesn't even come close to the 15 I traded in! The 15 would show around 20mpg on cruise at 65mph and the 19 is running around 17mpg on the same road.

Tough to compare a well broken in one against one that is new and running winter fuel.

Mine will runs well over 20 at 65 mph on cruise, flat and no wind.

They do regen more often than LML, but the regen's are shorter.


I'd expect your 65 mph on cruise mpg to improve significantly.

I hope you are right. I have had a 06, 11, 13, 15, and now this 19 and I don't seem to remember a big break in period but I could be wrong.

Yea I was surprised when in went into regen at 525 miles the first time and how fast it was done!

I just got 21.9 mpg (hand calculated) on a trip from North Alabama to the Smokey Mountains. My best, so far.

How many miles on the truck?

Mine sure is not getting better and I drive like old man right now.

About 46k. Mileage improved about 1 - 1.5 mpg after I put the banks Derringer and CAI on it.

Averaged about 75 mph. I usually drive 5 mph over posted limits.

8.5 hauling a 40' trailer with 2 cars and loads of heavy tools in it. Averaging about 65-70 MPH. Really seemed to suck up the DEF with the big load on it.
