Drivers can use 'zero fuel' with this little-known trick, says expert

Motorists can travel using “zero fuel” by using a simple tip that many motorists will be unaware of. According to experts, simply coasting along with a foot off the accelerator could be a simple way to cut down on consumption.

Gordon Wallis, fuel expert at Your NRG, stressed that petrol and diesel motorists who limit how often they press down on the throttle pedal could take advantage of a built-in tool. According to specialists, coasting in gear will activate the Deceleration Fuel Cut-Off (DFCO) system. The simple feature stops fuel injection, which allows cars to burn no fuel at all when a vehicle is decelerating.

Gordon explained: “When you lift your foot off the accelerator but keep the car in gear, the engine is driven by the wheels, not fuel.

“That means your car can effectively use zero fuel while slowing down. It’s a clever bit of engineering that most drivers are benefiting from without even realising it.

“As long as your car was built in the last 25 to 30 years, it’s highly likely to have DFCO built in. You just need to adjust your driving style slightly to take advantage of it.”

Data from RAC Fuel Watch shows petrol and diesel fees are slightly up in July, which could be a blow to owners. Unleaded petrol fees stand at 134.64p per litre, up from the 132.08p recorded in the middle of June. Diesel fees are also up at 134.64p per litre, up from the 132.21p at the start of last month.

Experts at the RAC have previously warned that “keeping the car moving at the right speed” was vital to saving fuel. The breakdown experts said road users should gently use the steering, accelerator and brakes to ensure they are not overly erratic.

The RAC also confirmed that cruising while remaining in gear would activate the fuel cut-off switch.

They added: “It’s one of the simplest habits to adopt. Ease off the throttle early and allow the car to naturally slow itself down while in gear. You stay in control, reduce brake wear, and burn no fuel while doing it.

“In a time where fuel costs are unpredictable and every pound counts, using your vehicle’s existing technology to save money just makes sense. It’s better for your budget, better for your car, and better for the environment.”
