Since the oil change period is directly related to the technical state of the diesel engine, the use conditions, and the quality of the oil, it should be handled flexibly according to the specific conditions. If the technical condition of the locomotive is not good, the oil should be changed in advance.
Here are two ways to determine the oil change period:
1. Compare the new oil and the used oil to a white filter paper. If there are more black spots in the used oil droplets, it means that the oil has not deteriorated and should not be replaced. If the oil is dark brown, it will be deteriorated. Should be replaced.
2. Use two glass tubes of 0.5 cm in diameter and 20 cm in length, respectively, to load 19 cm of new oil and used engine oil. After sealing, the two tubes are inverted at the same time, and the time of bubble rise is recorded. If the difference between the two exceeds 20 When %, it means that the used oil has dropped too much and should be replaced.
