There are various types of engine oil commonly used in diesel generators, and multiple factors need to be considered when selecting, including ambient temperature, engine oil type, fuel type, and engine oil additives. Here are some commonly used types of diesel generator oil:
Oil type:
W-50 engine oil: In southern China, engine oil with a viscosity of 20W50 is considered a seasonal oil and can be used throughout the year. However, in northern regions, due to winter temperatures potentially dropping below minus 15 degrees Celsius, this type of engine oil may no longer be suitable, which could lead to issues such as difficulty starting the engine.
10W-40 or 10W-30 engine oil: Diesel engines typically recommend using these types of engine oil. These engine oils can form an oil film inside the engine, providing lubrication and protecting the engine from wear and overheating.
15W-40 engine oil: This is a model that is compatible with both cold and non cold regions. For diesel generator sets in areas with long-term temperatures above 0 degrees Celsius, this high viscosity engine oil can also be chosen.
Oil brand:
There are various well-known diesel engine oil brands in the market, such as Longrun Lubricant "Long March 1", Mobil Super Black Tyrant, Longfu Diesel Engine Oil, Fully Synthetic Diesel Engine Oil, Great Wall Diesel Engine Oil, etc. These brands offer a variety of engine oils in different specifications and models to meet the needs of different diesel generators.
Oil change cycle:
Usually, the oil change cycle is set at 250 hours or one month to ensure the stability and durability of the engine. The oil change cycle is particularly important for new engines during the first 50 hours of operation and within 50 hours after maintenance or major repairs. In addition, the replacement of engine oil is usually carried out simultaneously with the replacement of the oil filter (element).
Please note that the above information is for reference only. When selecting diesel generator oil, it is recommended to choose according to the local ambient temperature, engine model, and manufacturer's specified standards, and consult professional opinions.
