A fuel dispensing pump capable of calculating and reporting specific fuel consumption of motor vehicles after refueling. The fuel pump has a computer, and a fuel measuring device, a keypad, and a display screen all functionally connected to the computer. A user enters the distance traveled or time of travel. The computer utilizes the entered distance or time value together with the quantity of measured dispensed fuel to derive a specific consumption value. This value is optionally displayed on the display screen. In a further option, the computer retains records for each user and calculates and reports specific fuel consumption over the period of time that the user has refueled in the past at the pump. Preferably, the pump has a printer for printing receipts, and the calculated value is printed on the receipt.
