One of the standout features of SM grade oil is its advanced detergent and dispersant additives. These help keep the engine clean by preventing the formation of sludge, varnish, and harmful deposits. As a result, engines run smoother and maintain better efficiency over time. SM oils also offer excellent wear protection, reducing friction between critical moving parts like pistons, cams, and bearings, thereby extending engine life.
Additionally, SM grade oil is designed for better compatibility with engines using modern emission control systems. It delivers stable performance across a wide range of temperatures, supports easier cold starts, and maintains its viscosity even under heavy load. Available in popular viscosity grades such as 10W-30, 10W-40, and 20W-40, SM engine oils are suitable for cars, motorcycles, and light commercial vehicles as recommended by manufacturers. Overall, SM grade oil is a reliable choice for drivers seeking clean engine operation, reduced wear, and long-lasting protection.
