Tuesday i filled the truck up and we (wife and 3 kids with a smaller cooler and few bags so not too much weight), jumped on NYS thruway north for 2.5 hrs to an amusement park, 6hrs there and then 2.5 hrs home with cruise set at 70-73 (troopers every few miles it seemed like) the whole trip there and back and best was 17.8....View attachment 180200
It went to 17.8 right before we got off the thruway...
Fyi and btw......this was with my range unplugged. we are going to do the same exact trip either next week or soon and i will plug the range in and see the difference.....stay tuned...... to be continued.....on our next episode.....etc, etc, etc....

Did you reset the average MPG gauge when you filled up before the trip? Otherwise, it's including the MPG from all the driving since the last time it was reset.

I reset mine every fill up as well. Not sure how else to get an accurate mpg count besides the dic.
It is in the glove box. My RPO code is GU6 so I have 3.42. I used to have a Tahoe that had 3.08 and that thing was a dog. I had to mash the gas everywhere and gas mileage suffered.

If all your driving is the same, then it's not gonna change much. But, if you reset it before a trip, you'll see what MPG you're averaging just on that trip. I never thought about this until I had an '02 Grand Cherokee with the 4.0. It seemed to stay stuck around 17.5 MPG. I was messing with the menu on the overhead display one day before a trip and reset the MPG thing. A couple hours into the trip, I was pushing 20 MPG as if I suddenly found a way to increase the fuel economy by 3 MPG! Those few hours of highway cruising isn't enough to raise your overall average MPG much when it includes the months of city driving into the averaging.
