After the initial use or maintenance of a diesel generator set, it is necessary to add engine oil before operation. The amount of engine oil used in a diesel generator set is a sensitive topic, and excessive or insufficient use of engine oil can cause certain harm to the set. So, I will provide you with an explanation on where to fill the engine oil level. Meihua Diesel Generator Factory is a company specializing in the research and development and manufacturing of power generation equipment. The company produces and sells many brands as agents. If you need a series of generator sets such as Weichai, Cummins, Yuchai, and Shangchai, please feel free to contact us for inquiries.

1： The oil level of diesel generator sets should not be too high
Under normal circumstances, diesel generator set users believe that the higher the oil level in the oil pan, the better, but this is actually a misconception. The oil level inside the bottom shell is not as high as it should be. When the oil level is too high, engine oil can easily enter the combustion chamber, causing the exhaust pipe to spray engine oil and emit blue smoke. This not only wastes engine oil and increases consumption, but also generates a large amount of carbon deposits due to incomplete combustion of engine oil, exacerbating the wear of pistons and cylinder liners, valves and valve seats, and even causing piston rings to bite, seriously affecting the normal operation of diesel engines.

2： The oil level of diesel generator sets should not be too low
At the same time, the oil level inside the diesel oil pan should not be too low. If the oil level is too low, it can cause poor lubrication, high oil temperature, and early wear of mating parts. Especially when going downhill, crossing ridges, or braking suddenly, it is possible to expose the oil surface of the oil filter, suck air into the oil pump and fail to supply oil, resulting in serious accidents such as "holding the shaft" and "burning the bearing".

3： How high is the appropriate oil level for diesel generator sets?
So, what is the appropriate height for the oil level of the diesel generator set oil pan? The editor of Meihua Power Generation Unit suggests that everyone use an oil level gauge to make judgments and read the oil level. The oil level should not be lower than the limit oil level mark or exceed the limit oil level mark, otherwise it is necessary to drain or add oil.
