The Liqui Moly Engine Oil Change Kit - 136357 is a comprehensive kit designed to make changing the engine oil in a car easy and efficient. This kit includes four essential products to complete an oil change: an oil filter, engine oil, an oil drain plug, and an oil pan. The oil filter is a crucial component that helps to remove impurities and debris from the engine oil, ensuring that the oil stays clean and effective. The engine oil is the primary lubricant for the car's engine, providing essential protection and reducing friction between moving parts. The oil drain plug is a small but critical part that allows for easy draining of the old oil from the engine. Finally, the oil pan is a container used to catch the old oil during the oil change process. Together, these products provide all the necessary components for a successful and efficient engine oil change.
