What will the OIL GARD system do when the oil level is low?

The OIL GARD system is designed to monitor the oil level in an engine to ensure proper lubrication and prevent damage that could occur due to low oil conditions. When the oil level falls below the safe operating threshold, the system takes preventative measures to protect the engine.

Stopping the engine is a critical response because it helps prevent severe engine damage that could result from continued operation without adequate lubrication. This action is crucial for maintaining the longevity and reliability of the engine by reducing the risk of seizure or mechanical failure caused by insufficient oil supply.

Other options, like alerting the operator or reducing engine power, may seem plausible, but they do not provide an immediate and direct protective measure against the risks posed by low oil levels as effectively as stopping the engine does. Engaging a safety lock usually relates to preventing the engine from starting under unsafe conditions rather than responding to low oil levels during operation.
