1. When using the parking heater in winter, you must pay attention to the selection of engine oil and choose the appropriate viscosity grade. 15W-40 can be applied -9.5 degrees to 50 degrees;
2. The use of parking heaters in winter also has requirements for the selection of diesel, so choose the appropriate label (freezing point). 5# diesel is suitable for use when the temperature is above 8℃; 0# diesel is suitable for use when the temperature is between 8℃ and 4℃; -10# diesel is suitable for use when the temperature is between 4℃ and -5℃; -20# diesel is suitable for use Use when the temperature is between -5℃ and -14℃;
3. When using the parking heater in winter, pay attention to installing a water jacket water heater, which can improve the cold start performance and fast load capacity of the engine, and also improve the emission in cold state;
4. Selection of coolant. If the water jacket water heater is not equipped, if the ambient temperature may be lower than 0 degrees, to prevent the coolant from freezing and damaging the engine and radiator, antifreeze is required.
