ABSTRACT:
A remote control for engine oil level indicator assembly for incorporation with the dipstick assembly of a vehicle engine for determining when the oil level reaches a point when oil should be added. This remote oil level indicator includes an air valve assembly that has a tube connecting it to the dipstick assembly, as well as a second tube furnished with a manually-operated plunger associated with the vehicle dashboard within reach of the driver, as well as an electrical switch having an air-actuated switch connector for closing the switch. Associated with this switch is an electrical lamp on the dashboard that is connected to a source of electrical energy (car battery) such that when the ignition switch is closed the lamp will be energized. The manual plunger is used by the driver to increase the air pressure within the air valve assembly to cause the movable switch connector to function by rising up to energize the lamp circuit and inform him or her of the level of the oil in the reservoir and that travel conditions are satisfactory to proceed.
