A built-in feature present in most modern petrol and diesel cars could save drivers significantly at the pump
Drivers are being tipped off about a savvy driving technique that could see them save on fuel without having to ditch their petrol or diesel vehicles for an electric alternative. The trick lies in a feature already installed in the majority of contemporary cars, which could lead to substantial savings at the filling station.
Fuel expert Gordon Wallis from Your NRG has shed light on the benefits of coasting in gear, which triggers the Deceleration Fuel Cut-Off (DFCO) system, effectively stopping fuel from being injected when decelerating under certain conditions.
Mr Wallis said: “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.”
Despite being a standard feature in cars since the 1990s, DFCO remains one of the least utilised tools for saving petrol, especially useful when going downhill, nearing crossroads, or during stop-and-go traffic, according to Mr Wallis.
With the average price of unleaded petrol lingering around 135p per litre and diesel exceeding 140p, Mr Wallis advises that mastering this more economical driving style is a shrewd move to cut costs.
He advised motorists: “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.”
He emphasised the benefits of engine braking over coasting in neutral, noting its safety and efficiency: “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.”
Highlighting the financial and environmental advantages, he added: “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.”
