Shell Rimula R7 Plus AM 5W-20
Shell Rimula R7 Plus AM 5W-20 is a premium fully synthetic heavy-duty diesel engine oil developed to support the performance and efficiency of the latest generation of low-emission diesel engines. The lubricant combines advanced synthetic base oil technology with Shell’s high-performance Low-SAPS additive system to deliver enhanced fuel economy, reduced emissions and reliable engine protection. The formulation helps reduce internal engine friction while maintaining a strong lubricating film between moving components, supporting both engine durability and improved operational efficiency.
One of the key advantages of Shell Rimula R7 Plus AM 5W-20 is its enhanced fuel economy capability. The lubricant features a reduced High Temperature High Shear (HTHS) viscosity which helps reduce internal engine friction and improve engine efficiency. Compared with higher viscosity engine oils such as SAE 15W-40, 10W-40, 10W-30 or 5W-30 high HTHS oils, this lower viscosity formulation can help reduce fuel consumption while still providing reliable engine protection and durability. This improved efficiency can help fleet operators reduce fuel costs and improve overall vehicle performance.
Shell Rimula R7 Plus AM 5W-20 also supports extended oil drain intervals and reduced maintenance requirements. The formulation is designed to meet long oil drain requirements for the latest Euro 6 engines, helping operators optimise maintenance schedules and control maintenance costs. By maintaining excellent resistance to oxidation and deposit formation, the oil continues to deliver reliable lubrication performance throughout extended service intervals.
Another important benefit of Shell Rimula R7 Plus AM 5W-20 is its compatibility with modern emission control systems. Many modern diesel engines use advanced exhaust after-treatment technologies such as diesel particulate filters (DPF) and catalytic reduction systems. The advanced low-ash formulation helps control deposit formation that could block or poison these systems, helping maintain vehicle emission compliance while supporting efficient engine operation.
Shell Rimula R7 Plus AM 5W-20 also provides strong protection against wear and deposits. The advanced additive technology helps maintain high levels of piston cleanliness while protecting critical engine components from wear. This contributes to longer engine life and consistent engine performance even in demanding operating environments.
Shell Rimula R7 Plus AM 5W-20 is particularly suited for modern on-highway heavy-duty diesel applications using the latest engine technologies. It is specifically recommended for the latest MAN engine platforms and is approved against MAN M 3977. It also meets Scania LDF-5 requirements, making it suitable for advanced heavy-duty engines operating under strict emissions regulations. Due to its specialised formulation, the oil is not backward compatible with older engines designed for higher viscosity lubricants.
Physical characteristics include a kinematic viscosity of approximately 45 mm²/s at 40°C and 8.2 mm²/s at 100°C with a high temperature high shear viscosity of approximately 2.6 mPa·s. The oil has a density of approximately 845 kg/m³ at 15°C, a flash point of approximately 239°C and a pour point of approximately –40°C, supporting reliable lubrication performance across a wide range of operating conditions.
