Öljyluokitus

Öljyluokitus refers to the classification system used for lubricating oils. This system helps consumers and professionals understand the properties and intended applications of different oil products. The most widely recognized oil classification system is the SAE (Society of Automotive Engineers) viscosity grade, which categorizes oils based on their thickness at different temperatures. For engine oils, common SAE grades include 5W-30, 10W-40, and 20W-50, where the 'W' stands for winter. Lower numbers indicate thinner oils that flow better in cold conditions, while higher numbers indicate thicker oils suitable for warmer temperatures.

Beyond viscosity, other classification systems exist to describe an oil's performance characteristics. For automotive engine oils, the API (American Petroleum Institute) service categories are crucial. These categories, such as API SN or API SP, indicate the oil's suitability for specific engine types and its ability to protect against wear, sludge, and deposits. Different regions and industries may also have their own specific classification standards. For example, in Europe, ACEA (European Automobile Manufacturers' Association) sequences provide performance standards tailored to European engine designs and emission regulations. Understanding these classifications is essential for selecting the correct oil to ensure optimal engine performance, longevity, and protection.
