An oil change is a fundamental aspect of vehicle maintenance that involves replacing the old, dirty engine oil with new, clean oil. This straightforward process is crucial for ensuring the engine runs smoothly and efficiently. Over time, engine oil breaks down and becomes contaminated, losing its ability to lubricate the engine's moving parts effectively. Without regular oil changes, the engine can suffer from wear and tear, leading to potential damage and costly repairs. In this piece, we will delve into the significance of oil changes, discussing how they contribute to the longevity and performance of your car.
