1. Spark plug
Spark plug directly affects the acceleration performance and fuel consumption performance of the engine. When driving, I feel that the engine power is insufficient, so I need to check and maintain it once; When you find that your car has problems such as idling jitter, starting difficulty or engine performance degradation, you need to replace the spark plug in most cases.
Spark plugs have different service life and replacement time. Copper-nickel spark plugs should be replaced at 30,000-50,000 km, platinum spark plugs at 6-8 km and iridium spark plugs at 65,438+00 km.
When choosing a spark plug, first determine the model and temperature of the car. According to different materials, it is generally recommended to replace ordinary spark plugs for 30,000 kilometers; Platinum spark plug 60000 km replacement; Iridium spark plug 80000 km replacement.
2. Machine lubricating oil
The lubrication and speed-up of the engine are greatly affected by the rotation of gears and oil. Engine oil is equivalent to engine lubricant, which has a great influence on the service life of automobiles. To ensure the service life of the car, it is necessary to use the oil correctly and change the oil regularly. Cars should have their oil changed every 5,000 km to 7,000 km. When changing the oil, please confirm whether the height of the oil is between "L" and "H", and confirm after adding the oil.
3. Brake block
Brake pad is the most critical safety component in the whole braking system. The working principle of brake pads is mainly to use the friction between brake pads and brake discs and between tires and the ground to stop the car. Therefore, a good brake pad is a safe protector. Generally, the thickness of a brand-new brake pad is about1.5cm. If the thickness of your brake pad is less than 0.5cm, it needs to be replaced immediately. Yue Ming Group reminds that for your travel safety, it should be replaced every 50,000 kilometers, and carbon deposits should be removed regularly.
4. Three filters:
The three filter elements of the car are equivalent to the lungs of the human body, filtering and purifying the body. The three filter elements of an automobile are: oil filter element+air filter element+air conditioning filter element. The oil filter needs to be changed when changing the oil, and the air conditioner filter needs to be checked for odor.
With the increase of car age and mileage, the technical condition of any car will gradually deteriorate, so we must do a good job in car maintenance, not only to protect the car, but also for our own safety!
