How Often Should the Diesel Generator Set change Engine Oil

The replacement of diesel generator set oil can ensure the stable use of the generator set, which also effectively prolongs the service life of the diesel generator set to a certain extent. The oil used by different diesel generator manufacturers and diesel generator sets of different powers is not the same. Under normal circumstances, the new engine needs to change the oil after the first 50 hours of operation. The oil replacement cycle is generally carried out at the same time as the oil filter (filter element). The general oil replacement cycle is 250 hours or one month.

Engine oil is usually used for lubrication, cooling, sealing, heat conduction and rust prevention of diesel generator sets. The surface of each moving part of diesel generator sets is covered with lubricating oil to form an oil film, which effectively avoids heat and wear of parts.

We all know that different diesel generator manufacturers and different power diesel generator sets use different oils. Under normal circumstances, the new engine needs to be replaced after the first 50 hours of operation. The replacement cycle of engine oil is generally the same as that of the oil filter (filter element) is carried out at the same time, and the general oil replacement cycle is 250 hours or one month. Use 2 types of oil, the oil can be extended after 400 hours of work before being replaced once, but the oil filter (filter element) must be replaced.

It is especially worth noting that if the diesel generator set has been overhauled and worked for 50 hours, the oil must be replaced, and its oil filter must also be cleaned at the same time. This is because when the unit is overhauled, its various parts must be run-in, which will polish the parts of the movement smoothly, and those with sharp edges and corners will become dust and fall into the oil.

Some users may not remember how long the unit has been working. At this time, you can use a simpler method to determine whether the oil needs to be changed: that is, put a drop of new oil and used oil on a piece of white paper at the same time. If the used engine oil turns dark brown, it means it has deteriorated and needs to be replaced.

The replacement of diesel generator set oil can well guarantee the stable use of the generator set, which also effectively prolongs the service life of the diesel generator set to a certain extent. Therefore, the replacement time of the oil must be accurately determined during the use of the diesel generator set.
