The neutralisation number is an index which indicates the content of acids or bases in lubricating oils. It is specified for industrial lubricants such as gear oils, hydraulic oils or chain oils.

Fully synthetic oils are artificially created lubricating oils which have improved oil properties compared to mineral oils. The fully synthetic oils are produced by chemical processes such as synthesis technologies or polymerisation.

Semi-synthetic oil is a mixture of synthetic oils and mineral oils. The proportion of synthetic oils from Group IV base oils and Group V base oils must be at least 10%.

Shear stability describes the property of an oil to resist the action of shear forces and the related mechanical destruction by breaking and tearing. It is the resistance to changes in viscosity.

The term HC synthetic oil refers to a base oil of a lubricant which is refined by the production process of hydrocracking. HC stands for Hydrocracking. HC synthetic oil is a highly refined mineral oil with a high purity level.
