How to Read Motor Oil Specifications?
1 Answers
Motor oil specifications can be identified by checking the SAE and API markings on the oil's outer packaging. SAE stands for the Society of Automotive Engineers, while API represents the American Petroleum Institute. The number following SAE indicates the oil's viscosity grade, whereas the code after API denotes the oil's quality classification. Motor oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. It is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts, as well as to clean sludge and varnish from the engine.
