I have wondered about the accuracy of the fuel mileage function. At home I filled the fuel tank to overflow on a level floor. On the next fuel stop I filled to overflowing on a level pad. I used the low tech method of figuring mpg--pencil & paper. I then compared my results with the DD ProDriver & it matched to a tenth.
