Now offering an upgraded technology, top-tier high performing HDDEO lubricant to the market. Shell Rimula R6 LME Plus is the first step into the future of HDDEO product development. Offering the latest specs including API CK-4, while laying the foundation for the next generation of Shell Rimula products.

Shell Rimula R6 LME Plus is formulated with Dynamic Protection Plus Technology that combines synthetic base oil technology and our Adaptive Additive Technology to provide outstanding engine protection:

  • Its adaptive technology protects against engine wear across all terrains and weather conditions, it offers proven start-up capabilities at extreme temperatures.
  • It is designed to protect engines in many different environments, which results in longer oil-drain intervals and longer engine life.
  • It fights against acid and deposit build-up so that the engine is protected under various conditions.

HOW DOES SHELL RIMULA R6 LME Plus PROTECT? Developed to provide extended oil drain performance using Shell’s unique Dynamic Protection Plus technology, for high performance and extended oil drain capability in the latest low emission engine hardware. It features low sulphated ash, phosphorus and sulphur (SAPS) additive technology and a unique anti-wear system.

Shell’s Dynamic Protection Plus technology combines Synthetic base oil which can include PurePlus technology and Adaptive Additive Technology to provide exceptional cleanliness and viscosity stability control and low temperature pumping characteristics. Shell Rimula R6 LME Plus is especially recommended for Euro VI emission requirements.


European FE field test compared the average fuel economy of 6 different engine oils in 6 European trucks meeting EURO VI. Shell Rimula R6 LME Plus 5W-30 gave over 2.8% fuel economy compared to an SAE 15W-40 oil. This can significantly help reduce Total Cost of Ownership (TCO). For example if a fleet owner spends Euro 50K per year on fuel with a standard SAE 15W-40 lubricant.  If they then switch to Rimula R6 LME Plus 5W-30, they can potentially save up to Euro 1400 per year on fuel- which is a substantial saving! When compared to an SAE 10W-40 oil it can give up to 2% fuel economy.


Engine wear protection 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.Incorporates soot-dispersant additives to keep particles finely dispersed and to help prevent soot-induced wear. Excessive wear of the cam lobes and tappets in an engine can result in a loss of power and increased engine emissions. Helps to prevent wear in an engine’s most critical components.


Shell Rimula R6 LME Plus offers improved oxidation control; it has over 95% improved viscosity control in the rigorous Volvo T-13 test compared with the API CK-4 limit. Excellent oxidation control helps to prevent oil thickening and harmful deposits in all areas of the engine.


Shear stability is a measure of an oil’s ability to resist mechanical degradation under severe stress. Being sheared into smaller parts can reduce an oil’s viscosity, which may result in failure to protect vital engine parts. In the ASTM D7109 test, Shell Rimula R6 LME Plus demonstrates strong shear stability. Shell Rimula R6 LME Plus remains well within the SAE 30 range even after 400 passes through the Bosch Shear Stability test.


EGR introduces some exhaust gas into the inlet air charge to reduce peak combustion temperatures.These gases contain acids (sulphurous and sulphuric) and soot particles that can have a detrimental effect on oil performance in terms of corrosion and sootinduced wear. EGR leads to higher oil temperatures, which stress the oil further.

Shell Rimula R6 LME Plus with Dynamic Protection Plus technology shows excellent performance in the severe tests on engines equipped with EGR that were introduced into the API CJ-4 specification, i.e., Mack T-12 (lead corrosion and piston ring and cylinder liner wear) and Cummins ISB (valve train wear under high soot conditions).
