This guide describes how to replace the engine oil and oil filter on a Kawasaki Ninja 300. Obtain 3 litres of Motul 5100 SAE 10W40 oil and an HIFLO HF303 oil filter. Position the motorcycle on the side stand. Start the engine, allow it to reach operating temperature, and then switch off. Place a container for collecting the used oil under the engine. Using a ratchet and a 17mm socket, unscrew the oil drain plug located under the engine on the right side. Allow the oil to drain and clean the plug thoroughly. Use a 65mm socket to unscrew the oil filter located at the front of the engine between the two exhaust headers. Lubricate the seal of the new filter with oil, screw it in by hand, and then tighten it a turn with the socket. Screw in the oil drain plug. Open the oil filler cap located on the right side of the engine casing. Pour in the oil, referring to the inspection hole at the bottom of the casing. Start the engine for a minute and switch off. Check the oil level again.
