Shell Rimula R4 X 15W-40
Shell Rimula R4 X 15W-40 is a high-performance heavy-duty diesel engine oil designed to provide dependable protection and performance across a wide range of diesel engine applications. Developed with Shell’s Triple Protection technology, the lubricant helps protect engines against wear, deposit formation and oil breakdown under demanding operating conditions. This advanced formulation supports engine durability and reliability while helping reduce maintenance requirements for vehicles and equipment operating in challenging environments.
One of the key advantages of Shell Rimula R4 X 15W-40 is its ability to provide strong protection against engine wear. Modern heavy-duty diesel engines operate under high loads and temperatures, placing significant stress on engine components. The oil contains advanced anti-wear additives that form protective films between metal surfaces, particularly in critical areas such as the valve train, piston rings and cylinder liners. These additives help reduce friction and prevent metal-to-metal contact, extending component life and supporting long-term engine reliability.
Shell Rimula R4 X 15W-40 also provides excellent control of acids and corrosion. During combustion, diesel fuel can produce harmful acidic compounds that may contribute to corrosion of engine components. The oil’s advanced detergent system helps neutralise these acids and prevent chemical corrosion of engine bearings and other internal metal surfaces. This helps maintain engine durability and protect key components throughout the oil service interval.
Another important benefit of Shell Rimula R4 X 15W-40 is its ability to control deposits and sludge formation within the engine. The carefully balanced detergent and dispersant additive system helps prevent oil thickening and the build-up of harmful deposits throughout the engine, including piston deposits and sludge in critical lubrication areas. By keeping engines cleaner than previous generation products such as Shell Rimula R3 oils, the lubricant helps maintain engine performance and operational efficiency over time.
Shell Rimula R4 X 15W-40 is suitable for use in a wide range of heavy-duty diesel engines operating in both on-highway and off-highway environments. It provides demonstrated protection and performance in modern high-power diesel engines produced by major European, American and Japanese manufacturers. The oil is suitable for engines meeting Euro 5, Euro 4, Euro 3 and earlier emission standards as well as US 2002 emission requirements. It can also be used with biodiesel fuels when following OEM recommended oil drain intervals.
The lubricant meets a wide range of industry specifications including API CI-4, CH-4 and ACEA E7, E5 and E3. It also carries approvals and recommendations from major equipment manufacturers including Cummins, Caterpillar, Volvo, Renault Trucks, Mack, MAN, MTU and others. Physical characteristics include a kinematic viscosity of approximately 109 mm²/s at 40°C and 14.7 mm²/s at 100°C with a viscosity index of approximately 139. The oil has a density of approximately 0.881 kg/l at 15°C, a flash point of approximately 230°C and a pour point of approximately –36°C, supporting reliable lubrication performance in demanding diesel engine operating conditions.
