In general, the new unit will operate for 50 hours after the first operation and 50 hours after the intermediate repair or overhaul. The oil change cycle is generally carried out at the same time as the oil filter (filter element), and the general oil change cycle is 250 hours or one month. With type 2 oil, the oil can be extended to work for 400 hours before changing, but the oil filter (filter element) must be replaced. If you want to determine the exact replacement time of diesel generator, you need to know some of the judgment methods. In this issue, we will take you to know how to determine whether the engine oil needs to be changed
1. Two glass tubes with a diameter of 0.5cm and a length of 20cm are used to fill 19cm of new oil and used oil respectively. After sealing, the two tubes are inverted at the same time, and the rising time of bubbles is recorded. If the difference between the two is more than 20%, it means that the viscosity of used oil drops too much and should be replaced.
2. Compare the new engine oil and the used engine oil on the white filter paper. If there are more black spots in the used oil drops, it indicates that the oil has not deteriorated and should not be replaced; if the oil is dark brown, it is deteriorated and should be replaced.
We also need to pay attention to the fact that different manufacturers and different powers of diesel generator oil is different, so when you purchase a diesel generator, you must ask the manufacturer what kind of oil is used for the unit, so as to avoid damage to the diesel generator set!
