Diesel generators are replaced with oil to ensure stable operation of the unit. However, many users are not sure about the timing of changing the oil. To replace the oil too early will result in cost waste. If it is not replaced in time, it will damage the unit. It is really difficult. Today, Starlight teaches you some methods of judgment, allowing you to accurately determine when to change the oil.

Under normal circumstances, the new unit is 50 hours after the first work and 50 hours after the repair or overhaul. The oil oil replacement cycle is generally carried out simultaneously with the oil filter (filter element). The general oil change cycle is 250 hours or one month. With Class 2 oil, the oil can be replaced after 400 hours of work, but the oil filter (filter element) must be replaced. If you want to determine the exact replacement time of a diesel generator, you need to know some of the determination methods:

1. Using two glass tubes of 0.5 cm in diameter and 20 cm in length, respectively, load 19 cm of new engine oil and used engine oil. After sealing, the two tubes are inverted at the same time to record the time when the bubbles rise. If it exceeds 20%, the used oil will drop too much and should be replaced.

2. Compare the new engine 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, then For deterioration, it should be replaced.

Another point to note is that the oil used by different manufacturers and diesel generators of different powers is different. Therefore, when purchasing a diesel generator, you must ask the manufacturer what type of oil the unit uses.
