If the oil filter gets clogged, what does the system use?

In the context of an oil system, if the oil filter becomes clogged, the system utilizes an oil bypass system. This is crucial for ensuring that the engine can continue to receive lubrication even when the filter is obstructed. The bypass allows oil to flow directly from the oil pump to the engine without going through the filter, which helps to prevent potential damage that could occur from insufficient lubrication.

Although filtered oil is critical for engine health under normal operating conditions, a clogged filter would impede that flow. Unfiltered oil would not help maintain optimal engine operation, as it could introduce contaminants that the filter usually removes. Therefore, in situations where the filter is not functioning properly, the oil bypass system is designed to maintain oil circulation and protect engine functionality.
