FWIW I've recorded and reset the AVG MPG display at each fillup for ~53k miles since new. All my fillup data goes into an Excel spreadsheet to allow analysis. With 188 data points (fillups) to date:
Maximum (+) difference between display MPG and calculated (odo miles/pump gallons) MPG = 11%
Maximum (-) difference between display MPG and calculated (odo miles/pump gallons) MPG = 5%
Number of zero-difference data points = 18
Average difference over all data points = +2% (display MPG higher than calculated MPG)
One obvious 'error source' in this comparison is inconsistent fill-level at each fillup, though I try to minimize that.
This on a '14 Escape 2.0 EcoBoost ('single scroll' turbo) running 87 octane for the first 8261 mile, 93 octane thereafter. The Escape's sensors, instrumentation and calculating algorithms should be identical to a similar MKC.
Just FYI for the stats geeks.

(looking forward to dealer arrival for a hands-on test)
