The Liqui Moly Engine Oil Change Kit - 451791 is a comprehensive set of products designed to aid in the process of changing the engine oil in a car. This kit includes four essential components: an engine oil filter, an oil drain plug, a crush washer, and a bottle of engine oil. These items work together to help ensure a smooth and efficient oil change for your car.

The engine oil filter is a vital part of the kit, as it helps to remove impurities and contaminants from the engine oil, keeping it clean and free of debris. The oil drain plug is used to drain the old oil from the engine, allowing for a fresh batch to be added. The crush washer is a small but important component that helps to create a tight seal between the oil drain plug and the oil pan, preventing leaks.

Lastly, the kit includes a bottle of engine oil, which is the main product needed for an oil change. The specific type and amount of oil included in the kit may vary, but it is typically enough to fully refill the engine with fresh oil.

Overall, the Liqui Moly Engine Oil Change Kit - 451791 is a convenient and practical solution for those looking to perform an oil change on their car. With all the necessary components included, this kit makes the process easier and more efficient.
