What can happen if engine oil is not changed regularly?

Regularly changing engine oil is crucial for maintaining the health of an engine. Over time, engine oil breaks down and loses its effectiveness due to the accumulation of contaminants, heat, and oxidation. If engine oil is not changed regularly, it can become dirty and less effective at lubricating engine components. This reduced lubrication increases friction between moving parts, leading to greater wear and tear on the engine.

As wear progresses, the risk of engine failure rises, as crucial components may become damaged or unable to function properly. Increased wear can also lead to overheating due to the lack of effective lubrication, further compounding the potential issues. Regular oil changes help to ensure that the engine stays lubricated, clean, and functioning optimally, thus prolonging its lifespan and maintaining performance.
