2.grade diesel engine oil
3.according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements.PCVRegularly replace the engine oil and oil filter. The quality of lubricating oil will change during use regardless of its grade. To prevent malfunctions, oil should be changed regularly in accordance with the car’s usage conditions, and the oil level should be kept at an appropriate amount.PCVMaintain good ventilation in the crankcase. Most modern gasoline engines are equipped withPCVvalves, but pollutants in blow-by gases can accumulate around the
4.valves, potentially causing blockages. Therefore, it is necessary to regularly clean the pollutants around the
5.valves.
6.Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, and oxides of sulfur and nitrogen from the combustion chamber enter the crankcase through the gaps between the piston rings and cylinder walls, mixing with metal particles generated from component wear to form sludge. Therefore, the crankcase should be cleaned regularly to keep the interior of the engine clean.
