When I inputted in my two vehicles, I was asked for my highest and lowest mileage trip data. Strangely, I cannot input tenths of a mile, so I had to input the mileage rounded to the nearest whole mile. Since I was asked for mileage, I inputted the furthest and shortest distance on the tank.

Then, when I look up the individual vehicles as listed in the mileage database, instead of highest and lowest mileage, it's listed as Best and Worst trip, alluding to best and worst MPG, unknown if that's for a tankful or for some measured distance. Very confusing.

So which is it? Highest MPG per tank or furthest distance on a tank?

I'm not about to re-enter in all of my tank data (16 for my 2004, 99 for my 2001), is there an easier upload data option?
