A method is used to control a fuel level gauge of a vehicle system and includes: monitoring, via an engine controller, a fuel economy of the vehicle system; comparing, via the engine controller, the fuel economy with a predetermined fuel economy threshold to determine whether the fuel economy is less than the predetermined fuel economy threshold; adjusting, via the engine controller, a sensitivity of a display filter in response to determining that the fuel economy is less than the predetermined fuel economy threshold for a predetermined amount of time in order to maximize an accuracy of the fuel level gauge, wherein the display filter smoothes an unfiltered fuel level signal received from a fuel level sensor of the vehicle system, thereby generating a filtered fuel level signal; and controlling, via an instrument panel controller, the fuel level gauge of the vehicle system.

A process is provided for monitoring the amount of fuel remaining in a vehicle's storage tank, the vehicle including a fuel level sensor. The process includes the steps of searching for a refueling event, establishing a base line fuel level utilizing the fuel level sensor when a refueling event is detected, tracking fuel consumption, and calculating the amount of fuel remaining in the storage tank as a function of fuel consumption and the base line fuel level.
