Shell Rimula R4 X

Designed to Provide Triple Protection

Shell Rimula (R4 X) is formulated with Shell’s innovative Dynamic Protection technology, which features an advanced additive system that adapts to your engine’s specific requirements. This helps to provide protection in three key areas:

• acid and corrosion control: It protects against corrosion by controlling the acids formed as the fuel burns¹
• wear control: It maintains strongly protective oil films to keep critical engine components working.¹
• deposit control: It resists high-temperature oxidation, thereby keeping engines clean from deposits¹

Shell Rimula R4X provides:

• Up to 50% better engine cleanliness¹
  Up to 50% more cleanliness control, i.e., less engine sludge, in different parts of the engine has been demonstrated in key engine tests for meeting US and European specifications.
• Up to 50% better acid corrosion protection¹
  Shell Rimula R4 X is proven to give up to 50% more protection in engine and laboratory tests and field trials under real-world truck driving conditions.

Up to 30%* better protection against engine wear.

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.

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.
