A car oil change is essential for engine maintenance. The process begins with parking the vehicle on a level surface and allowing the engine to cool. The car is then lifted using a jack for access to the oil pan. The oil drain plug is removed, allowing old oil to drain into a pan. After draining, the old oil filter is replaced with a new one, applying a small amount of oil to the new filter’s gasket for a proper seal. The drain plug is reinstalled securely.

Next, the car is lowered, and new oil is added through the oil filler cap, ensuring the correct type and quantity specified by the manufacturer. The engine is started and run briefly to circulate the new oil, after which the oil level is rechecked and adjusted if necessary. Finally, the old oil and filter are disposed of properly, completing the oil change and ensuring the engine runs smoothly and efficiently.
