Using this oil change kit is a breeze. First, make sure your car engine is cool before starting the oil change. Place a drain pan under the oil drain plug and carefully remove the plug using the appropriate tool. Let the old oil drain completely. Then, replace the old oil drain plug gasket with the new one provided in the kit and reinstall the drain plug. Next, remove the old oil filter and install the new K&N oil filter. Pour the Motul synthetic engine oil into the engine through the oil filler cap. Check the oil level using the dipstick and make sure it's at the right level. As for maintenance, it's recommended to change the oil according to your car's manufacturer's schedule. Also, always keep an eye on the oil level between oil changes. If you notice any leaks or strange noises from the engine, have it checked by a professional right away.
