Shell Rimula R7 AX 5W-30
Shell Rimula R7 AX 5W-30 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. Formulated using advanced synthetic base oil technology and high-performance Low-SAPS additive systems, the lubricant helps deliver improved fuel economy, reduced emissions and reliable engine protection. The formulation is designed to meet the requirements of modern heavy-duty engines operating under demanding conditions while helping fleet operators optimise fuel efficiency and maintenance intervals.
One of the key advantages of Shell Rimula R7 AX 5W-30 is its enhanced fuel economy capability. The lubricant features reduced High Temperature High Shear (HTHS) viscosity, which helps reduce internal engine friction and improve overall engine efficiency. By lowering friction while maintaining effective lubrication, the oil can help reduce fuel consumption compared with higher viscosity oils such as SAE 15W-40 or conventional 10W-40 engine oils. This improved efficiency can help reduce operating costs and improve fleet fuel performance without compromising engine durability.
Shell Rimula R7 AX 5W-30 also supports modern emission control technologies. The advanced low-ash formulation helps protect exhaust after-treatment devices such as diesel particulate filters (DPF) and catalytic systems by reducing deposit formation and preventing contamination. This helps maintain compliance with strict emissions regulations while supporting efficient engine operation and long-term reliability.
Another important benefit of Shell Rimula R7 AX 5W-30 is its ability to support extended maintenance intervals. The formulation is designed to meet long oil drain requirements for modern Euro 6 engines, allowing fleet operators to optimise maintenance scheduling and reduce downtime. By maintaining excellent oxidation resistance and deposit control, the lubricant continues to provide reliable engine protection throughout extended service intervals.
Shell Rimula R7 AX 5W-30 also provides strong protection against wear and deposits. The advanced additive system delivers high levels of piston cleanliness and helps protect critical engine components from wear during operation. This contributes to longer engine life and helps maintain consistent engine performance even under demanding operating conditions.
Shell Rimula R7 AX 5W-30 is particularly suited for modern on-highway heavy-duty applications using the latest Euro 6 engine technologies. It is recommended for engines such as Mercedes-Benz OM 470, OM 471, OM 473, OM 934, OM 936 and OM 936h where API FA-4 performance levels are required. Due to its specialised low HTHS formulation, the oil is not backward compatible with older engines designed for higher viscosity grades.
The lubricant meets key industry and OEM specifications including API FA-4 and ACEA F01 and carries approvals from manufacturers including Cummins, Detroit Diesel, Volvo, Renault Trucks and Mack. Physical characteristics include a kinematic viscosity of approximately 60 mm²/s at 40°C and 10 mm²/s at 100°C with a high temperature high shear viscosity of approximately 2.9 mPa·s. The oil has a density of approximately 843 kg/m³ at 15°C, a flash point of approximately 236°C and a pour point of approximately –51°C, supporting reliable lubrication performance across a wide range of operating conditions.
