Shell FuelSave

At Shell, we’re always looking for ways to get more from our fuels – and from your vehicle’s engine. Our scientists’ dedicated pursuit of this vision means that new Shell fuels, are our most efficient.²

From the moment you start the engine, new Shell FuelSave Unleaded helps protect your engine. It contains DYNAFLEX technology that helps reduce engine friction the instant you put it in your car, whether you are cruising the highway or stuck in traffic.³ And Shell FuelSave Diesel has new dirt-busting molecules for a clean and efficient engine,¹ so you can focus on enjoying the drive.

All our fuels are designed for efficiency.⁴ Because wherever you go, we want you to go with confidence.

Shell FuelSave Unleaded

With new friction-reducing and increased dirt-busting technology.⁵

Benefits

The new Shell FuelSave Unleaded has 20% more friction-reducing molecules than our previous formulations.⁶ It contains our new DYNAFLEX technology, which helps reduces wasted energy to help your engine run efficiently from the moment you start your engine.⁴

Shell FuelSave Diesel

New Shell FuelSave Diesel is designed to keep your engine clean and protected for efficient running.¹

Benefits

In two different industry standard tests, new Shell FuelSave Diesel kept fuel injectors significantly cleaner than our previous formulation.⁵ That’s because it contains new dirt-busting molecules for a clean and efficient engine.⁷

Fuel myths vs. fuel facts

Have you heard the one about the fuel-saving magnet? Here we debunk five fuel efficiency myths to help you start saving fuel and drive smarter.

Myth #1:

Fill up when it’s cooler

Facts: The thinking goes: colder fuel will have a higher density, giving you more energy per litre at the pump. However, fuel is kept in underground storage tanks that maintain a constant temperature. Which means air temperature has little effect on your fuel’s density.

Myth #2:

Changing your air filter always saves fuel

Facts: Modern cars have a computerized system designed to regulate fuel flow – so a small difference in airflow is unlikely use more fuel. However, if the air filter does get blocked the overall engine performance is likely to be reduced so it’s good to keep up regular maintenance.

Myth #3:

Restarting your engine uses more fuel than running idle

Facts: If your engine’s running, it’s using up fuel. As a rule if you’re stopping for over 10 seconds, switch off your engine.

Myth #4:

Cruising in neutral uses no fuel

Fact: It is extremely dangerous to drive in “neutral” as you are not in full control of the vehicle. Concerning fuel consumption cruising in neutral can use more fuel than driving in gear because the amount of fuel required to maintain optimum performance is determined by the Engine Management System. In many vehicles, fuel supply is essentially stopped when the foot is taken off the accelerator pedal whilst travelling in gear, whereas under conditions of idle (neutral / no gear), fuel is supplied to the engine to keep the engine running.
