In most old cars such as a late 80's or 90's Buick Century, the fuel is gauged by a float within the tank rather than sensors attached to the tank. With this being the case, the fuel sloshes around in the tank while driving (especially when accelerating, braking, or turning) so the float gives an erratic reading.
