Shell Rimula R7 Plus AI 0W-20
Shell Rimula R7 Plus AI 0W-20 is a premium fully synthetic heavy-duty diesel engine oil developed to support the latest generation of high-efficiency, low-emission diesel engines. Formulated with advanced synthetic base oils and high-performance Low-SAPS additive technology, the lubricant is designed to deliver enhanced fuel economy, reduced emissions and reliable engine protection. The formulation reduces internal engine friction while maintaining a durable lubricating film between moving components, helping support both engine durability and operational efficiency in modern heavy-duty applications.
One of the key advantages of Shell Rimula R7 Plus AI 0W-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 overall engine efficiency. Compared with higher viscosity engine oils such as SAE 15W-40, 10W-40 or 10W-30, the lower viscosity formulation can help reduce fuel consumption while still delivering effective lubrication and engine protection. This improved efficiency can help fleet operators lower operating costs while maintaining reliable engine performance.
Shell Rimula R7 Plus AI 0W-20 also supports extended oil drain intervals and reduced maintenance requirements. The lubricant is designed to meet long oil drain requirements for the latest Euro 6 engines, helping operators optimise maintenance schedules and minimise downtime. By maintaining excellent resistance to oxidation and deposit formation, the oil continues to provide reliable protection throughout extended service intervals.
Another important benefit of Shell Rimula R7 Plus AI 0W-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 the build-up of deposits that could block or poison these systems, supporting emission compliance while maintaining engine efficiency.
Shell Rimula R7 Plus AI 0W-20 also delivers 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 long engine life and consistent engine performance even in demanding operating conditions.
Shell Rimula R7 Plus AI 0W-20 is particularly suited for modern on-highway heavy-duty applications using the latest engine technologies. It is specifically recommended for use in the latest Iveco engines where the Iveco 18-1804 TLV LS specification is required. Due to its specialised low HTHS formulation, the oil is not backward compatible with older engine designs that require higher viscosity grades.
Physical characteristics include a kinematic viscosity of approximately 43 mm²/s at 40°C and 7.8 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 210°C and a pour point of approximately –39°C, supporting reliable lubrication performance across a wide range of operating conditions.
