If you want to change the oil, it is better to drain the oil by gravity. The pumping oil cannot be pumped clean, and the pipe may get stuck during the process of pulling out the pipe.

Engine oil is called the blood of the engine. Engine oil plays the role of lubrication, cleaning, sealing, heat dissipation, buffering, and rust prevention in the engine. The oil needs to be changed regularly. The traditional method of changing the oil is to raise the car with a lift, remove the oil drain screw of the engine oil pan, and then drain the old oil and add new oil. However, many 4s shops or repair shops have begun to use oil pumps to pump out the oil. This oil change method is actually unable to pump out the old oil. Therefore, it is recommended that riders use the gravity oil change method to replace the oil. Every time the oil is changed, the oil filter element needs to be replaced together. When buying filter elements, you need to buy products of big brands. Inferior filter elements have poor filtering effect, and long-term use will damage the engine. When buying engine oil, it is recommended that you choose fully synthetic engine oil. Although fully synthetic motor oil is more expensive, it has better lubrication performance and longer service life. When using the car in normal times, you must change the oil regularly and maintain it regularly, so that the car can always be kept in a good condition. If it is not maintained for a long time or is not maintained on time, it will aggravate the wear and tear of the engine.
