The Shell Nitrogen Enriched Cleaning System uses a patented molecule, which cleans and protects intake valves and fuel injectors. Enriching the molecule with nitrogen makes it more thermally stable and therefore more effective in tough engine conditions with higher temperatures and increased pressures. This is particularly important in modern fuel-efficient engines to prevent the breakdown of cleaning agents.

The Nitrogen Enriched Cleaning System gives all three grades of Shell gasoline the ability to clean up gunk on intake valves and fuel injectors. Industry data indicate and car manufacturers recognize that a clean engine is more fuel-efficient, produces fewer emissions and allows vehicles to perform at their best.
