Honest to God that's what it got. I know the speedometer and odometer were virtually right on, double checked the total mileage (and compared it to what my friend in my Challenger got) and the total amount of gas used and it came to 19MPG - actually just a hair less - 18.9 but close enough to 19. Also only made 2 passes down the track which most likely helped and never did more than 65 out on the road.
