Shell Rimula R4 L 15W-40 CK4
Shell Rimula R4 L 15W-40 CK4 is a high-performance heavy-duty diesel engine oil designed to provide reliable protection for modern low-emission diesel engines operating under severe conditions. Formulated with advanced low-SAPS (sulphated ash, phosphorus and sulphur) additive technology and high-quality base oils, the lubricant delivers strong protection against wear, deposits and thermal breakdown while supporting the performance of modern exhaust after-treatment systems.
A key advantage of Shell Rimula R4 L 15W-40 CK4 is its ability to support the durability and efficiency of low-emission engines. Modern diesel engines often use after-treatment technologies such as diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems to reduce emissions. The advanced low-ash formulation helps minimise the risk of blocking or poisoning these emission control devices, helping maintain emissions compliance while supporting fuel efficiency and reliable engine operation.
Shell Rimula R4 L 15W-40 CK4 also provides outstanding protection against engine wear. The lubricant has demonstrated strong wear protection performance over millions of kilometres of real-world service. By forming a durable lubricating film between moving engine components, it helps reduce friction and protect critical parts such as pistons, cylinder liners and bearings. This helps extend engine life and maintain engine performance even in demanding operating environments.
Another important benefit of Shell Rimula R4 L 15W-40 CK4 is its ability to help reduce operating costs for fleet operators. The oil features an enhanced acid-control system designed to support flexible oil drain intervals while maintaining effective protection throughout the service life of the lubricant. This helps operators optimise maintenance schedules and reduce downtime while ensuring reliable engine protection.
Shell Rimula R4 L 15W-40 CK4 is suitable for use in a wide range of heavy-duty diesel engine applications including trucks, buses and off-highway equipment operating in industries such as construction and agriculture. It meets the requirements of many major European and North American engine manufacturers for modern low-emission diesel engines and can also be used in applications where high sulphur fuels may be present.
The lubricant meets a wide range of industry and OEM specifications including API CK-4, CJ-4, CI-4 Plus, CI-4, CH-4 and API SN as well as ACEA E7, E9 and E11. It also carries approvals from major manufacturers including Cummins, Caterpillar, Volvo, Renault Trucks, Mack, MAN, Detroit Diesel and others. Physical characteristics include a kinematic viscosity of approximately 115 mm²/s at 40°C and 15.3 mm²/s at 100°C with a viscosity index of approximately 139. The oil has a density of approximately 0.876 kg/l at 15°C, a flash point of approximately 236°C and a pour point of approximately –35°C, supporting reliable performance across a wide range of operating conditions.
