What can be prevented by performing pre-lubrication before starting an engine?

Pre-lubrication before starting an engine is crucial for preventing excessive wear on engine components. This process ensures that vital engine components, such as bearings, pistons, and camshaft, are coated with engine oil prior to ignition. When an engine is started, there is typically a brief moment where moving parts are not adequately lubricated, which can lead to metal-to-metal contact. This contact can cause wear and tear on these components, ultimately reducing their lifespan and potentially leading to engine failure.

By pre-lubricating, you create a protective film of oil that minimizes friction during that critical initial phase, allowing the engine to run smoothly and efficiently from the moment it starts. This preventative measure is essential in maintaining engine health, extending service intervals, and ensuring reliability over time.
