My 2014 R/T gas mileage at 55mph

Net elevation change of +336ft. I traveled from Kingston, NY to Castleton on Hudson, NY with cruise control set at 55mph. I filled up at the gas station in Kingston, and reset my average fuel economy gauge when I left the gas station. There's about a minute of local traffic before getting to the highway, and about 5 minutes of local driving before I get back to my house.

I hit 35.0mpg before I exited the highway.

Regarding the accuracy of the fuel economy reading. I'd say there's a 1.0mpg maximum margin of error. It's usually within a 0.5mpg proximity.

My 2014 tracks much better than my 2011 did, so there might have been some software changes. I have noticed that the range displayed on the fuel economy gauge is a little different in the '14 than that which was in the '11. I've tracked every mile I've driven on this car with more fuel receipts in my glove box than I care to look at. I'll enter them on at some point, but I've been entering them on an app on my Note4. I did a factory reset recently which wiped all my records out, so I will have to re-enter these at some point.
