Drivers can use 'zero fuel' with this little-known trick
Motorists are being urged to follow this smart driving advice, which could result in them using less fuel while on the road. According to experts, drivers could save cash at the petrol pump by simply doing one thing.
All motorists have to do is take their foot off the accelerator. The advice centres around a built-in feature present in most modern petrol and diesel cars, and it could save drivers significantly when fuelling up.
Gordon Wallis, fuel expert at Your NRG, said coasting in gear activates a system known as Deceleration Fuel Cut-Off (DFCO). This feature halts fuel injection during certain driving conditions, allowing the car to burn no fuel while decelerating.
He 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.'
This system has been standard in most cars since the mid-1990s and reportedly remains one of the most underused fuel-saving features, particularly helpful during downhill stretches, approaching junctions, or easing off in traffic.
With unleaded fuel still averaging around 135p per litre and diesel over 140p, experts believe learning to drive more efficiently is a smart way to reduce spending.
Gordon added: '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 adds that it's safer and more effective than coasting in neutral and can easily become second nature with practice.
He said: '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.'

Another car expert recently highlighted three key areas of your vehicle that need to be checked for optimal fuel economy - including the 30,000 mile rule.
TikTok user chequanlaosi (@chequanlaosi) emphasised in a social media video that spark plugs need to be replaced regularly to maximise a car's mileage.
While some spark plugs can last more than 100,000 miles, drivers will see the most benefit from a change every 30,000 miles, according to Bob Moore Auto Group.
The TikTok presenter added that worn spark plugs will reduce your car's power and increase fuel consumption.
Next, the car expert in the clip mentions how a vehicle's canister purge valve under the hood can remain open, allowing fuel vapour to continuously enter the engine and raise fuel consumption.

Drivers warned to never ignore 'sweet smell' as it could cost you £1,000 in repairs
A seemingly pleasant smell that seems to be coming from the air freshener - or even the car itself - could be a warning sign that something is wrong with a car Cruising along with the windows up, you might catch a whiff of a sweet aroma in your car and think someone's popped in a delightful air freshener or it's the lingering scent of a new car. However, an automotive expert warns that this seemingly innocuous smell could actually be a cry for help from your vehicle. Many drivers would brush off such a scent without a second thought, especially since it isn't a burning odour which would typically raise alarms. Yet, specialists are flagging this particular sweet smell as a critical alert from your motor. This comes after the news of ' anyone buying fuel next week given '£15 charge' warning by The AA '. READ MORE: The Summer I Turned Pretty has major twist and fans are on the edge of their seats "Drivers often dismiss sweet smells in their cars as nothing to worry about, but this particular scent is one of the most misunderstood warning signs I encounter," said Kazimieras Urbonas, Supplier Excellence Manager at Ovoko. The spokesperson for one of Europe 's leading online marketplaces for pre-owned car parts said: "What might seem pleasant can indicate a serious problem that, if left unchecked, could leave you with repair bills exceeding £1,000." That delightful sweet smell, which becomes more pronounced when the engine heats up or the heater is on, is usually a sign that your car's coolant system needs urgent attention, reports the Daily Record. Urbonas explained that the scent is most likely coolant, or antifreeze, and ignoring it could lead to catastrophic engine failure. This is because the coolant shouldn't be seeping into the interior of your car. The liquid emits a distinctively sweet, almost syrupy odour that can easily mislead drivers into believing it's benign. "Coolant has ethylene glycol in it, which gives off that characteristic sweet odour," explained Urbonas. He continued, adding: "The problem is that when you can smell it inside your car, it means the coolant is escaping from where it should be, usually through a leak in the heater core or damaged hoses". You'll often detect this aroma most strongly in the footwell area, wafting through the air vents, or pervading the entire cabin. It tends to become more noticeable when your engine is running hot or when the heating is on, as these conditions increase the strain on the cooling system. A faulty heater core is frequently to blame for this sweet-smelling issue. Located behind your dashboard, it utilises hot coolant to heat the air entering your cabin, and if it leaks, coolant may drip into your vehicle's ventilation system. "Heater core problems are particularly sneaky because they're hidden away behind the dashboard," shared Urbonas. "You might not see any obvious puddles under your car, but the coolant is still escaping – it's just doing so inside your vehicle instead of underneath it," said the manager. Damaged coolant hoses are another potential cause for concern. These hoses transport coolant around your engine bay and can, over time, suffer from cracks or loose connections that let coolant leak out and evaporate, leading to that sweet scent infiltrating your car. It's typical for motorists to presume the scent originates from something innocent, but this is an error. Air fresheners, cleaning products used during car washes, or even certain synthetic materials in newer vehicles can produce sweet fragrances that appear similar. Urbonas went on: "I've had customers tell me they thought someone had spilt perfume in their car, or that their air freshener just happened to be particularly strong that day. The dangerous part is that people often adapt to smells over time, so what starts as noticeable can become background noise, until the real damage is already done". Dismissing this sweet aroma can result in several serious complications. Engine overheating is the most immediate worry, as your cooling system can't function properly with insufficient coolant levels. Beyond mechanical harm, there are health considerations too. Coolant vapours can be toxic, particularly in confined spaces, and extended exposure isn't something you want to risk. He warned that "what people may not realise is that coolant leaks can also lead to mould growth in your ventilation system. The moisture creates perfect conditions for mould and bacteria to thrive, which then gets blown directly into the cabin every time you use your air conditioning or heating". What to do Scout for damp or sticky spots on your car's carpets, especially around the footwell areas. Peek at your coolant reservoir under the bonnet - if it's frequently low despite topping up, you're probably dealing with a leak. Misty windows that pop up out of the blue could also be a sign of coolant vapour inside your vehicle. This occurs when coolant evaporates and then settles on the glass surfaces of your car. "Don't try to diagnose exactly where the leak is coming from yourself," ended the expert. Concluding by urging drivers to "get your car to a qualified mechanic who can perform a pressure test on your cooling system. This will show exactly where coolant is escaping and how serious the problem is". Finally, Urbonas said: "From my experience in the parts industry, heater core replacements are among the more expensive repairs car owners face. The part itself isn't necessarily costly, but the labour involved in accessing it – which often means removing the entire dashboard – can push repair bills well over £1,000".

Motorists warned 'be aware of age limit' for parking in Aldi, Sainsbury's, Morrisons and Asda
Not adhering to this common rule can leave drivers out of pocket Parking in the supermarket is pretty straightforward with bays all set out and disabled areas clearly marked. But motorists are being warned that they need to follow the 'age limit' in stores such as Asda, Aldi, Sainsbury's and Morrisons or face fines. The rules of parent and child spaces, which are a feature in most supermarket car parks, give families extra space to allow getting children in and out of the vehicle safer. This extra room is helpful for parents who are getting buggies or car seats out of their vehicles. They are usually closer to the store entrance as well to prevent youngsters from having to walk across busy areas. But the rules around who can and cannot use them is not always clear unless there are visible signs to lay out the conditions of use. Drivers could be subject to fines, however, if they break a simple upper 'age-limit' rule for these bays, reports The Express. Experts at EMG Motor Group claimed rules were "fairly simple" to understand with bays only available for use by parents or guardians who are taking a child under 12 into the shop. The age is set at 12 as this is when youngsters must still use car seats or restraints when in the passenger seat. And although there is no hard rule, road users could be at risk of a hefty £100 charge in a nightmare end to a shopping trip. The experts explained: "No, there is no law against parking in a parent and child parking space without a child under 12 with you, but you are risking a PCN (Parking Charge Notice), the same as if you incorrectly used a disabled parking bay. "This is because the car parks are usually owned privately, for example, by supermarkets, and so they enforce rules allowed by their Accredited Trade Association (ATA) status.

"If you're confused as to the rules in a particular car park, it's worth checking with the store or destination that you're parking at, so that you don't risk a fine, which could be up to £100, being slapped on your windscreen." However, there is still a grey area around whether expectant mothers can use the bays and take advantage of the extra space. Officials at the RAC said: "Parent and child bays are reserved for parents or guardians with one or more children under 12 years old. "It's unclear whether pregnant women can use the spaces and probably best to ask an individual store manager what their rules are." The RAC also advise speaking to the store manager if you spot someone using a parent and child space who shouldn't be. They suggest it is a better idea than approaching the driver yourself as this could lead to a hostile situation.
