Base Oil Physical and Chemical Properties
Base oil properties have a direct impact on the overall performance and lifetime of lubricants.
Base oil is a type of oil that is used as a base for lubricants. The main element of lubricants (volume-wise) is base oil and it forms about 95% of lubricant’s weight. In some lubricants (Compressor and hydraulic oil) 99% of the oil is consisted of base oil and only the 1% which is left contains additives. Base oils can be reached from oil-based and non-oil-based resources. Most of the base oils used in the world are obtained from crude oil refining.
