The Liqui Moly Oil Change Kit - 137261 is a comprehensive set of products designed to facilitate an oil change for a car. It includes five essential items, each serving a specific purpose in the oil change process. These items are a high-quality oil filter, engine oil, an oil drain plug, an oil drain plug gasket, and a service reminder sticker.

The oil filter is an essential component in the kit, responsible for removing impurities and contaminants from the engine oil. It helps to maintain the cleanliness of the oil, ensuring optimal engine performance and longevity.

The engine oil is the primary lubricant for the car's engine and is responsible for reducing friction and wear on engine components. It also helps to regulate engine temperature and prevent corrosion.

The oil drain plug is a vital part of the oil change process, as it allows for the draining of old oil from the engine. It is crucial to replace the drain plug with each oil change to ensure a secure seal and prevent oil leaks.

The oil drain plug gasket is a small but crucial piece that helps to create a tight seal between the oil drain plug and the engine. It helps to prevent oil leaks and maintain the integrity of the oil change.

Lastly, the service reminder sticker is a helpful tool for keeping track of when the next oil change is due. It can be placed on the windshield or in the car's service manual to serve as a reminder for the next maintenance interval.

Overall, the Liqui Moly Oil Change Kit - 137261 is a convenient and comprehensive package that includes all the necessary components for a successful and efficient oil change for a car.
