Look at the car wash beauty franchise is how to maintain the car:
1. Use the appropriate quality grade of lubricant
For gasoline engines, SD--SF gasoline engine oil should be selected according to the additional equipment and operating conditions of the intake and exhaust system; for diesel engines, CB diesel oil should be selected according to the mechanical load. The selection criteria are not lower than the manufacturer's service requirements. .
2. Regularly change the oil and filter
Lubricating oil of any quality grade will change during use. Deterioration in performance after a certain mileage will cause problems for the engine. In order to avoid sudden failures, the oil should be changed regularly according to the conditions of use, and the amount of oil should be moderate (usually the upper limit of the oil scale is better). If the filter blocks the oil and cannot pass through the filter element, it will swell the filter element or open the safety valve. When passing through the bypass valve, the dirt will still be brought back to the lubrication part, which will increase the internal pollution of the engine wear.
3. Keep the crankcase well ventilated
Most gasoline engines are now equipped with PCV valves (crankcase forced ventilation) to encourage the engine to ventilate, but the pollutants in the helium “will deposit around the PCV valve, which may block the valve. If the PCV valve is blocked, the pollution gas will reverse. The air filter is used to pollute the filter element, which reduces the filtering capacity. The inhaled mixture is dirty and the crankcase is polluted, resulting in increased fuel consumption, increased engine wear and even damage to the engine. Therefore, it is necessary to regularly maintain the PCV to clear the PCV valve. Contaminants around.
