1. Use The Right 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--CD diesel oil should be selected according to the mechanical load, and the selection criteria should be no lower than the manufacturer's requirements. Prevail.

2. Regularly Change The Oil And Filter

Lubricating oil of any quality grade will change during use. After a certain mileage, the performance deteriorates, which will bring various problems to the engine. In order to avoid the occurrence of faults, 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). When the oil passes through the pores of the filter, solid particles and viscous substances in the oil are accumulated in the filter. If the filter is clogged, the oil will not pass through the filter element, it will swell the filter element or open the safety valve, and pass through the bypass valve, still bring the dirt back to the lubrication part, causing the engine to wear and the internal pollution is intensified.

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 reduce the filter 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, the PCV must be regularly maintained. Remove contaminants around the PCV valve.
