Why the last fill-up record does not have any Fuel Efficiency (MPG) assigned to it?
Unlike some of the softwares that report the fuel efficiency (MPG) of your last tank in the same fill-up record, aCar assigns the fuel efficiency to the tank of gas that you have burnt to get it (the previous fill-up record). This way you can find out how a specific gas brand or gas octane performs in your car and compare that with other brands and octanes. Since it’s still not known how the last fill-up will perform, no fuel efficiency could be calculated and assigned to it.
