Motor oil plays a crucial role in maintaining the health and performance of your engine. It is responsible for lubricating the engine’s moving parts, reducing friction, and preventing wear and tear that could result in costly repairs. But motor oil does more than just lubricate; it also helps to cool the engine, clean out contaminants, and seal the gaps between moving parts to ensure that the engine operates smoothly and efficiently. Without adequate oil, the engine would overheat, leading to significant damage and possible failure.
How Oil Becomes Contaminated
As oil circulates through the engine, it picks up impurities such as dirt, metal shavings, carbon, and other contaminants. Over time, these particles build up, causing the oil to lose its effectiveness. The oil becomes thicker, which increases friction within the engine and reduces its ability to cool and lubricate. Additionally, as the oil breaks down from exposure to heat and pressure, it can lose its protective properties, leading to premature engine wear. Regular oil changes are essential to replace the contaminated oil and ensure that your engine is running optimally.
