Lubricating oil: a liquid lubricant used on various types of machinery to reduce friction, protect machinery and machined parts, mainly for lubrication, cooling, rust prevention, cleaning, sealing, and buffering purposes.
Gear picking oil is a type of automotive virtual potential oil, axle wheel worm oil, and industrial open gear oil in the infant industry. The International Organization for Standardization (ISO) has proposed the classification of "Lubricants, lubricants, and organic products - Part IV - Group H"
Gear oil is divided into two categories, one is vehicle gear oil, including manual transmission gear oil and rear axle gear oil; Another type is industrial gear oil, which is further divided into industrial closed gear oil.
Each type of lubricating grease has its common general physicochemical properties to indicate the intrinsic quality of the product. For lubricating oil, these general physicochemical properties are as follows:
Gasoline engine oil has developed with changes in engine design, application conditions, environmental protection, and energy-saving requirements, which are related to the production era of the engine. The current gasoline engine oil standard adopts API
The upgrading and replacement of gasoline engine oil specifications are driven by several factors, including increasingly stringent emissions standards for automobiles, fuel economy, technological advancements in the engine itself, and extended oil change intervals.
