Built around a deep knowledge of the operation and lubrication needs of heavy-duty diesel engines, our scientists and engineers have developed products built on technology that adapts chemically and physically to the changing conditions within the engine, ensuring your engines keep running, however you choose to run your equipment, or your business.

The Energised Protection of Shell Rimula heavy-duty diesel engine oils provides protection in three

critical areas:

  1. Acid control — helps protect against corrosion from acids formed as fuel burns
  2. Deposit control — helps to keep the engine clean for performance and long life
  3. Wear control — keeps moving metal engine surfaces apart for long engine life

Use Shell LubeMatch tool to find the right oil to protect your engine.

Learn more about how Shell Rimula provides protection for longer equipment life, even in some of the most challenging circumstances.

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

Whether it’s piston deposits or crankcase sludge, dirt in your engine can reduce its efficiency and increase your fuel costs.
'Carbon deposits on the pistons can cause piston rings to stick and may form an abrasive layer that leads to excessive wear. Worn piston components fit less precisely and allow oil into the combustion chamber. This increases oil consumption and lets combustion gases into the crankcase, which can prematurely age the remaining oil
Keith Selby - Technology Manager, Heavy-duty diesel engine oils

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 protection

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.
