As the auxiliary oil of the Cummins generator set, the generator manufacturer thinks that it is necessary to study the skills when picking out, to get rid of the habit of thinking and jump out of the misunderstanding. Why do you say this? Because we found that some users think that the oil is thicker and better. Here is the correct view for us. This is a wrong view.

The viscosity of the oil we see at room temperature does not represent its viscosity at high temperatures, nor does it represent its viscosity at low temperatures. The viscosity of the oil changes as the temperature changes. The high quality oil viscosity should be smooth at all temperatures and still have good fluidity at low temperatures. Not only that, but we also need to change the viscosity of the oil as the temperature changes, which requires a viscosity index improver to handle. Therefore, we can’t judge the quality of the oil according to the thick or thin oil at normal temperature, and the oil can save fuel.

The oil is used to smooth the moving parts of the diesel engine and to cool and dissipate these moving parts, carry impurities and avoid rust. The grade and quality of the oil used have an impact on the diesel generator set. It also has a certain impact on the service life of the oil. Therefore, we must select suitable oil products to fully maintain the operation of the Cummins generator set.
