How does oil protect my engine?

In many ways:

1. Cleaning the engine

Our oils are designed to clear away dirt, debris and deposits from engine components and to prevent blockages in important oil ways. The oil helps to lock up the dirt and render it harmless until it is removed at the next oil change.

2. Minimising friction and wear

our oils form a protective film over your engine components and have special additives that act between the moving surfaces to prevent contact and reduce drag. This helps your engine to operate as quietly and effectively as the designers intended.

3. Removing heat

Our oils carry heat away from hot areas, such as around the piston rings where the temperature can reach up to 320°C, and redistribute it around the engine.

4. Preventing corrosion and rust

Our oils help to protect your hard-working engine components from corrosion beyond the normal oil-change interval. Benchmarking studies show that Shell Helix oils provide best-in-class protection and help to extend your engine’s life and avoid some expensive repairs.
