Determining the oil change period of the diesel engine oil is very important. Changing the oil too late will accelerate the mechanical wear, and premature oil changes will cause waste. The oil change period is generally carried out according to the instructions, but due to the direct relationship between the oil change period and the technical condition of the diesel engine, the conditions of use, and the quality of the oil, it should be handled flexibly according to the specific circumstances. If the technical condition of the locomotive is poor and the oil quality is not good, the oil should be changed in advance. Here are two ways to determine the oil change period.
1. The new and old oil comparison method compares the new engine oil and the used motor oil on the white filter paper. If there are more black spots in the used oil droplets, it indicates that the engine oil has not deteriorated and should not be replaced; for example, the engine oil is dark brown , it is bad, it should be replaced.
2. The glass tube test method uses two glass test tubes with a diameter of 0.5 cm and a length of 20 cm. They are respectively filled with 19 cm of new motor oil and used engine oil. When the two tubes are sealed, they are inverted at the same time to record the rising time of the bubbles. A difference of more than 20% indicates that the viscosity of used oil drops too much and should be replaced.
