How Oil Functions In Your Car’s Engine

As we have discussed in the previous section, regular oil changes are crucial to maintaining a healthy engine. But what happens if you neglect this important task? Let’s explore.

Firstly, as your car runs with old and dirty oil, it starts losing its viscosity. Viscosity is the measure of how thick or thin the oil is. Over time, contaminants like dirt, debris, and metal particles accumulate in the oil and make it thicker. As a result, it cannot lubricate the engine parts properly leading to increased friction between them.

Secondly, skipping an oil change also affects the performance of your car’s oil filter. The job of an oil filter is to remove impurities from the engine oil before they can cause damage to critical engine parts. When you don’t change your oil regularly, these impurities build up on the surface of the filter making it clogged over time. A clogged filter restricts proper flow of oil resulting in lower pressure inside the engine leading to more wear and tear.

To sum up, ignoring regular oil changes not only reduces fuel efficiency but also causes serious harm to your vehicle’s engine components. It leads to decreased performance levels and increases the risk of costly repairs down the road.

By taking care of simple maintenance tasks like changing your car’s oil regularly and keeping up with oil filter maintenance, you can save yourself from bigger headaches in future without breaking your bank account!
