What may cause insufficient oil supply in an engine?

Insufficient oil supply in an engine can occur due to clogged oil passages. In a reciprocating engine, oil is essential for lubricating moving parts, maintaining proper temperature, and preventing wear and tear. When oil passages become clogged, the flow of oil is restricted or completely blocked, which can lead to inadequate lubrication of critical components like bearings, pistons, and camshafts. This can cause increased friction and heat, potentially leading to engine damage or failure.

In contrast, a full oil reservoir, a brand new oil filter, and frequent maintenance checks typically foster good oil circulation and management within the engine. A full oil reservoir ensures there is enough oil available for circulation, while a brand new oil filter is designed to effectively remove contaminants and ensure clean oil flows through the system. Frequent maintenance checks are vital for identifying potential issues and ensuring that all components are functioning correctly, thus preventing situations that could lead to clogged passages.
