Using this oil change kit is a breeze. First, make sure your engine is cool before starting the oil change. Locate the oil drain plug under the engine, remove it carefully, and let the old oil drain out completely. Replace the old oil drain plug gasket with the new one from the kit. Then, remove the old oil filter and install the new K&N oil filter. Pour the Motul synthetic engine oil into the engine. Make sure to check the oil level using the dipstick and add more oil if needed. As for maintenance, it's recommended to change the oil according to your vehicle's manufacturer's guidelines. Always store the kit in a cool and dry place. Also, don't forget to recycle the old oil and filter properly to protect the environment.
