摘要：
Low-temperature viscosity of lube oils mixed with paraffinic base oil and naphthenic base oil at different mass ratios has been tested by experiments.The influence of paraffinic base oil on the performance of naphthenic base oil was investigated by studying the low-temperature viscosity of tested oils.The viscosity of lube oils increased with an increasing content of high-viscosity paraffinic base oil in the oil mixture.And the low-temperature viscosity was less influenced when the content of paraffinic base oil in the mixture was insignificant. In order to reduce the cost for formulating lubricating oil,a small fraction of paraffinic base oil can be added into naphthenic base oil as far as the property of lubricating oil can meet the specification.According to the study on low-temperature viscosity of the oil mixed with paraffinic base oil and naphthenic base oil,a basic rule was worked out for the preparation of qualified lubricating oils.
