Green Lubricants (10w/30sg) Biodegradability Study

By describing in this paper the development general status and trend of the domestic and international gasoline engine oil, it is presented that the biodegradable engine oil should be developed. Analyze the properties of gasoline engine oil, the theory of the green lubricating oil degraded by aerobic microorganisms and the impact of the basic oil and additive on biodegradability, and introduce the experiment method determining the green lubricating oil biodegradability in the world at present. Select 10W/30 SG green lubricating oil, carry on experiment to compare its properties with the properties of mineral oil at the same level. The degradation course of 10W/30 SG green lubricating oil and its basic oils is stress researched. The results show: its quality has already reached the properties of 10W/30 SG gasoline engine oil; Both the green lubricating oil and its basic oil are biodegradable; The biodegradability of the latter is superior to the former obviously. Therefore function additives suppress the biodegradability of the green lubricating oil.
