We know you and your engine face many tough conditions on the road. So we strive to make your journeys easier. That’s why Shell scientists have developed Shell Rimula R4 X. It’s the new and improved engine oil that’s replacing your trusted Shell Rimula R3 X.
Up to 30%* better protection against engine wear.
Shell Rimula R4 X offers high level engine wear protection in critical areas of the valve train, piston ring and cylinder liner areas, and has been demonstrated in specification engine tests for API, ACEA and major engine manufacturers. This is achieved through the addition of specialised anti-wear additives which are designed to form protective films over the parts of your engine where needed most.
Up to 50%* more efficient at keeping your engine clean.
Shell Rimula R4 X helps to prevent oil thickening and formation of harmful deposits in all areas of the engine. To do this, Shell Rimula R4 X provides a high level of engine cleanliness through the use of optimized levels of specially selected soot dispersant additives.
Up to 50%* better protection against chemical corrosion.
Combustion gasses produce harmful acids that come into contact with oil in the piston ring belt area and pass into the oil sump. These acids are controlled using detergent additives, which neutralise acid and help to prevent piston deposits and the corrosion of metal surfaces. Shell Rimula R4 X offers excellent control of acids to help prevent the chemical corrosion of vital engine components.
