Petrol and diesel drivers could save almost £100 a year with 'simple hack'

Drivers could save almost £100 a year on fuel by using 'simple hacks'. According to RAC Fuel Watch, drivers are paying an average of 145.27p per litre for petrol and 150.41p for diesel.

Recent research suggests the UK had the third highest fuel prices across Europe - with the most expensive diesel costing about 7p per litre more than the second-placed nation Finland. Experts are now urging drivers to take advantage of a 'summer driving hack'.

With a heatwave predicted to sweep the UK next week, drivers might be tempted to turn up the air conditioning. But motorists are being warned to do something else instead.

Drivers should wind down their windows and create a through-draught to prevent cooling and provide air ventilation. When travelling longer distances along motorways and dual carriageways, the opposite should be done.

Using air conditioning when driving faster than 30mph can be more efficient as the extra drag created by open windows will negatively impact fuel economy, GB News reports. John Woosey, founder of Ripe Motorhome Insurance, said drivers could save £84.98 annually with a diesel car and £97.30 with petrol cars.

It means that during the summer months owners of diesel cars can save £21.20 and petrol car owners can save £24.30. He said: "As soaring fuel prices continue to impact motorists across the UK, driving has never been more expensive, with miles spent on the road really adding up.

"But aside from taking fewer journeys, it’s difficult to know how to drive more fuel efficiently day-to-day. Simple hacks such as turning off your air conditioning when driving at slower speeds may seem like a small change, but it can really add up in the long run."

Mr Woosey called on motorists to carry out maintenance on their air conditioning units to ensure they work at their maximum efficiency. The RAC suggests drivers should get a service on their air conditioning, and potentially even a change of refrigerant gas, every two years.

Drivers are also being urged to avoid filling up at motorway service stations if they can as service stations often charge massively inflated prices. Data shows drivers will pay more than 21p extra per litre when refuelling at service stations, with petrol at 166.7p and diesel at 172.74p a litre.
