Default Trip Summary MPG Accuracy

I'm a gas & go type, and never bothered to calculate my MPG.

Should I believe this? 2018 FLHXS, no drivetrain mods.

Yep, take the miles you rode and divide by gallons you put in the tank. Don't trust all these electronic things today. Open your eyes and ears to the "real world"

Best I've averaged with my 2017 Ultra has been 47 MPG. Most of the time it's between 42 and 44 MPG.
