Description
Shell Rimula R4 X 15W-40 (CI-4/E7/DH-1)
Heavy Duty Diesel Engine Oil from Shell
Description: Shell Rimula R4 X 15W-40 (CI-4/E7/DH-1) is an engine oil containing selected additives that are designed to provide Triple Protection to improve engine and oil durability in 3 critical areas:
- Acid and Corrosion Control
- Reduced Engine Wear
- Deposit Control
It helps to lower required maintenance and increase reliability of vehicles for long-term use. It is suitable for most heavy-duty diesel engines, non-turbocharged and turbocharged alike, for both on and off highway applications and has a wide array of engine manufacturers’ approvals.
Shell Rimula R4 X 15W-40 is also very resistant to high temperatures and the oxidative and thermal load resulting from this, so that the engine is kept clean internally, even at long drain intervals. Additionally, tests have shown that the product offers good protection against wear both when using fuels with a high sulphur content and when using fuels with low sulphur content.
Main Applications of Shell Rimula R4 X 15W-40
Shell Rimula R4 X 15W-40 has been specifically designed for use in heavy duty diesel engines that meet stringent requirements for exhaust emissions and require long, or even very long, oil drain intervals.
For use in commercial vehicles, in addition to excellent protection against wear, the product greatly limits the occurrence of corrosion and the internal contamination of the engine. This aspect is very important in case of use in emission-optimised engines, taking into account the sometimes considerable amount of soot that the oil has to absorb. Shell Rimula R4 X 15W-40 simultaneously meets the old and more recent specifications for commercial vehicle applications.
Benefits and Features of Shell Rimula R4 X 15W-40
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 15W40 offers 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 particles finely dispersed to help prevent wear.
Deposit Control
Shell Rimula R4 X 15W40 helps to prevent oil thickening and the formation 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 15W40 keeps engines cleaner than previous-generation Shell Rimula R3 products.
