A visual indicating system for displaying within a vehicle distance traveled per quantity of fuel used by the vehicle\s liquid fuel consuming engine. The system includes a fuel quantity and a distance traveled transducer each of which feeds electrical signals to a computer. The computer calculates a value of distance traveled per quantity of fuel used and records the calculated value a number of times n, adds the total number of values recorded and divides by n. The number 5 is chosen as an ideal value for n. The quotient is then visually displayed. The computer continues to calculate new values of distance traveled per quantity of fuel used. After each new calculation (when 5 is used for n) 4 displayed values are added to the new calculated value, the sum is divided by 5 and the quotient is visually displayed. This may also be done by storing all the inputs n in a single register with the new value added to the register and the most recently displayed value subtracted from the register and then divide the total value in the register by n to acquire a new value for display. Various other modifications and methods are disclosed.

A system for visually indicating on a display within a vehicle employing a liquid fuel consuming engine and road engaging propelling members the approximate distance traveled per quantity of fuel used by the vehicle, said system comprising: A. display means for visually indicating a given numerical value in response to an electrical input having a given characteristic; B. first transducer means for converting a given distance traveled by said vehicle into a first electrical output pulse having a given characteristic; C. second transducer means for converting a given amount of fuel used by said engine into a second electrical output pulse having a given characteristic; and D. computer means connected to receive the electrical outputs of said first and said second transducer means and to transmit an electrical input to said display means, said computer means being operable to: 1. count the total number of first pulses for a given number of second pulses, then calculate a distance traveled per quantity of fuel used value, then place said value a given number of times N in a register, then divide the total value in the register by n to determine a quotient, said n being equal to or greater than N, then forward said quotient to said display means via an electrical input to visually indicate said quotient; then 2. count another total number of first pulses for said given number of second pulses, then calculate another distance traveled per quantity of fuel used value, then add said other value to the register and subtract the displayed value from the register, then divide said new value of the register by n to determine a new quotient, then forward said new quotient to said display means via another electrical input to visually indicate said new quotient; and then 3. continue repeating the actions of paragraph D2.
