My 2015's lie-o-meter is accurate for highway miles. Where it goes off is in city driving, and paints a rosier picture than reality. In city driving, the truck calculates about 0.5 to 1 mpg better than hand calculations. My guess is that the sample rate of whatever sensor is measuring fuel flow is too slow to catch the spikes that occur during acceleration in city driving. Highway driving is a nice steady condition, easy to measure accurately.
I agree, it must be something along those lines. Glad I'm not the only one noticing this.
