Industries utilize a variety of lubricating oils tailored to specific applications. Common types include mineral oils, synthetic oils, and semi-synthetic blends. Mineral oils, derived from crude oil, are cost-effective and widely used. Synthetic oils, created through chemical processes, offer superior performance in extreme conditions. Semi-synthetic blends combine the advantages of both. Additives such as anti-wear agents, rust inhibitors, and viscosity modifiers enhance the oil’s properties. Industries carefully select lubricating oils based on factors like temperature, load, and operating environment to ensure optimal machinery performance and longevity.
