Mileage Readout

My NOX is the sixth car I've owned that will tell you what mileage you are getting. Three cars always had a dead on number compared to hand calculating, three always gave you a number that was one mpg higher than what I would hand calculate. The NOX falls into the category of giving you the higher than actual number. What is the experience out there?

My '10 always read about 2 higher than actual, while my '18 is very close to actual.

My '18 Terrain is within two tenths higher than the hand calculated MPG. It seems to be linear with the amount of fuel purchased. A fill of a near empty tank will be towards the two tenths. A fill with a half empty tank will be about one tenth.
