Acid protection
Acid protection
In the engine, combustion acids can escape into the crankcase. Low quality oils may fail to protect vital components from these acids, leading to corrosion that may cause catastrophic engine failure.
Shell Rimula oils contain powerful antioxidant agents that adapt chemically to neutralise acids before they can damage your oil and your engine.
Deposit protection
Deposit protection
Whether it’s piston deposits or crankcase sludge, dirt in your engine can reduce its efficiency and increase your fuel costs. Shell Rimula diesel engine oils contain molecules that adapt to remove and then block deposit-forming particles to help keep engines clean and protected.
Wear control
Wear control
Wear protection is particularly critical at high-pressure contact points, such as in the engine valve train and gearbox. Shell Rimula diesel engine oils have adaptive molecules that are designed to protect the engine by reacting under heat and pressure to form a protective film that helps to reduce wear.
