Abstract
A control system for an engine low oil sensor prevents engine starting if the oil level is below a predetermined level, but thereafter enables the engine to run uninterrupted even if the oil level becomes low during engine operation. After the engine is shut off for any reason, the control system resets so that the low oil switch is operable during the next attempted restart of the engine. The control system also includes a visual or audible indicator that indicates when engine starting is prevented due to a low oil condition.
