ABSTRACT:
An engine crankcase oil surveillance system with restoration of oil sufficiency. A vertical oil detection member extends down and into the engine sump. A timer is set for a specific period of time after initiation. The timer is initiated upon shut-off of the engine ignition system. An oil level indicator is activated when said timed period has taken place, and determines the sump oil level. An oil supply means is connected to a reservoir and to the oil level indicator for supplying reserve oil from the reservoir to the sump, upon indication by the oil level indicator that the sump oil level is below a predetermined level. The fluid from the reservoir is cut off the desired oil level is reached.
