In business, every penny saved counts. Whether you’re shuttling between appointments or embarking on long-haul journeys, managing fuel costs is paramount. That’s where Shell FuelSave Diesel comes in—a revolutionary fuel engineered to save you up to 1 litre per tank* without any additional expense.

From the moment you fill up with Shell FuelSave, you’ll begin reaping the benefits of its advanced fuel economy formula. Enriched with Shell Efficiency Improver, this fuel is meticulously designed to enhance fuel economy right from the get-go.

How Shell FuelSave Diesel supports engine efficiency

Shell FuelSave Diesel is Shell’s standard diesel fuel, developed with a specialist formulation that helps engines operate efficiently while supporting performance and protection.

Over time, deposits can collect around a diesel engine’s fuel injectors. This build-up may interfere with the way fuel is delivered and burned, potentially affecting power, fuel consumption and emissions. Shell FuelSave Diesel contains cleaning agents that help remove existing deposits and reduce further build-up within the fuel injection system.

The fuel also has a higher cetane number than conventional diesel. Cetane measures how readily diesel ignites during combustion. A higher cetane number can support smoother ignition, helping the engine run more quietly and efficiently.

How Shell Efficiency Improver works

Shell Efficiency Improver is designed to help the fuel ignite and burn more effectively. By supporting more efficient combustion, the formulation helps the engine make better use of the energy contained in every litre of diesel.

According to Shell, this could help drivers save up to one litre of fuel per tank.* The formula has been developed through extensive laboratory testing and on-road trials to provide reliable performance with every fill-up.

Whether you operate a few commercial vehicles or manage a large national fleet, Shell FuelSave Diesel provides a practical way to support engine cleanliness, fuel economy and everyday vehicle performance.
