Lubricating oils are commonly used in various types of vehicles and mechanical equipment to reduce friction, primarily providing functions such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. This lubricating oil product represents a weighted average of the following types: 'Hydraulic oil, unspecified type', 'Automotive engine oil, mineral type', 'Turbine oil, mineral type', 'Transformer oil, mineral type', 'Gear oil, unspecified type', 'Electric discharge machining oil, mineral type', 'Cutting fluid, unspecified type', 'Oil film bearing oil, unspecified type', and 'Rolling oil, unspecified type'. If the specific type of lubricating oil cannot be clearly identified, this dataset can be used. For specific technical details, For information description such as sections and boundary scopes, refer to the production datasets of various types of lubricating oils. Infrastructure such as production equipment manufacturing and factory construction is not included within the dataset boundary.
