Shell Rimula R6 M synthetic oil provides excellent protection for the most demanding diesel engines, while offering fuel economy, reduced emissions and the longest drain intervals in European-built engines. No matter how long and how difficult your vehicles and machinery operate—in heat, cold, dust, mud or rough terrain—you need an oil that will protect your engine. Shell Rimula provides intensive engine protection, preventing corrosion with additives that protect against acids formed during fuel combustion. It keeps the engine clean, which prolongs engine life and ensures optimum performance, while preventing mechanical wear, which prevents metal-to-metal contact and increases engine durability. Shell Rimula R6 M is ideal for fleet managers looking to reduce operating costs by offering a single lubrication solution for a range of vehicle makes and engine types, including Euro II, Euro III and some Euro IV engines. Compared to conventional SAE 15W-40 oils, Shell Rimula R6 M can also improve fuel efficiency by providing excellent protection against corrosion, deposits and wear, as well as extended drain intervals, which is recognised by leading engine manufacturers.
