Hand calculate your MPG's to get as accurate an idea as possible. My lie-o-meter and hand calculated MPG's mirror each other on my 1500 Silverado (so I guess my lie-o-meter, isn't a liar after all..:)) but that isn't always the case, plus your truck is so new.

They are not really lie-o-meters, many folks don't realize the average MPG calculated by the vehicle is over time, hand calculations are for each tank of fuel between fill-ups. I've notice the option to change your vehicle MPG calculations over the past x number of miles on some vehicles (not my 2013 Ram).

I did an experiment with my 2013 RAM 1500. For one year, I tracked the MPG reported by the truck and my hand calculations, the difference between the two methods was 0.837082108 MPG, the vehicle reading on the high side. I won't argue that the delta is significant but may be explainable given the expansion/contraction of gasoline and the error in filling the tank to exactly the same level at each fill-up.
