Shell Rimula R6 M is a synthetic oil designed to provide excellent protection for the most demanding diesel engines. It offers unique properties that contribute to fuel economy, reduced emissions and extended oil drain intervals, especially in European engines. Regardless of operating conditions, such as heat, cold, dust, mud or rough terrain, this oil guarantees reliable protection for engines in all circumstances. Shell Rimula R6 M provides intensive protection in key areas: it protects the engine from corrosion caused by acids formed during fuel combustion, prevents the formation of deposits, which prolongs engine life and optimises its performance, and minimises mechanical wear by reducing metal contact, which increases engine durability. It is the ideal solution for fleet managers who want to reduce operating costs by offering a single universal lubrication for a variety of vehicle makes and engine types, including those meeting Euro II, Euro III and some Euro IV standards. Compared to traditional SAE 15W-40 oils, Shell Rimula R6 M can also improve fuel efficiency. By using synthetic base oil technology and advanced additives, Shell Rimula R6 M provides improved protection against corrosion, deposits and wear. Laboratory tests have shown that this oil offers up to 30% greater effectiveness in preventing oxidation and significantly better resistance to soot-induced thickening.
