2011 LML and I have been doing a lot of highway driving (just bought). Have been happy at around 65-75 I calculated and it's close to DIC to be like 18mpg. Not bad at that speed with worn out Duratrac tires. My real question is I had it do it twice. The last time was yesterday I filled up and got on the road and for about 100-120 miles I was getting 14mpg if I am lucky. Took truck out this morning and reset the DIC and back up to 20mpg on highway. Seems very inconsistent, when I am getting 14 is that in regen? And if so does it usually last that long for like 100 miles?

I don't know where you live but I am convinced that the fuel here in the North east is of vastly different BTU counts. My LB7 goes through those same sort of swings tank to tank.
