Shell Rimula R4 X 15W-40
Shell Rimula R4 X is designed to provide Triple Protection to improve engine and oil durability. It helps to lower maintenance and increase reliability of vehicles. It’s suitable for most heavy-duty diesel engines for on and off highway applications.
Acid and Corrosion Control:
Shell Rimula R4 X shows excellent control of acids by reducing the accumulation of acids and chemical corrosion of engine bearings. Harmful acids from fuel combustion are controlled by using selected detergent additives to neutralise them and help to prevent corrosion of metal surfaces.
Reduced Engine Wear:
Shell Rimula R4 X offer high levels of engine wear protection in the critical areas of the valve train, piston ring and cylinder liners. This wear control is achieved through the addition of anti-wear additives that are designed to form protective films in metal-to-metal contacts when needed under different engine operating conditions, and by the use of soot dispersant additives to keep soot participles finely dispersed to help prevent wear.
Shell Rimula R4 X helps to prevent oil thickening and the formulation of harmful deposits in all areas of the engine, including sludge and piston deposits. The optimised detergent and dispersant additive system for Shell Rimula R4 X keeps engines cleaner than previous-generation Shell Rimula R3 products.
