An oil change is a routine maintenance task performed on a vehicle to keep its engine running smoothly and efficiently. The engine of a vehicle has many moving parts that require lubrication to reduce friction and prevent wear and tear. An oil change involves draining the old, dirty oil from the engine and replacing it with fresh, clean oil. An oil change is typically recommended every 3,000 to 5,000 miles but can vary depending on the vehicle’s make, model, and age. Regularly changing the engine oil will prolong the engine’s life, improve fuel efficiency, and maintain the overall performance of the vehicle.
