Petrol and diesel owners can reduce fuel use by 10 percent with ‘simple yet effective’ tip

Motorists can dramatically reduce their petrol and diesel fuel usage by following a series of simple techniques, according to experts. 

Three simple vehicle cooling techniques anyone can do today would dramatically reduce temperatures inside the cabin. 

As well as making journeys more comfortable for motorists, a cooler interior will ensure air conditioning units do not have to work so hard. 

In some cases, ensuring a vehicle stays in a cool condition can prevent the tool from being switched on at all which is likely to result in major savings down the line. 

Darren Miller from BigWantsYourCar.com opened up on simple tips which could help save the pennies this summer.

He explained: “Opening the windows before turning on the air conditioning is a simple yet effective way to start the cooling process in your vehicle. 

“By letting hot air escape first, you lighten the load on your AC system, possibly reducing fuel consumption by up to 10 percent.

“Fanning the interior by swinging a door back and forth might seem unconventional, but it’s a smart trick to push out trapped hot air from your car. 

“This quick action helps refresh the cabin quickly, making your ride more comfortable, especially in hot temperatures.

“Redirecting cool air to the footwells not only refreshes your feet but also helps push hot air out through open windows. 

“This strategic way of using your car’s ventilation system improves airflow, creating a cooler interior without overworking your AC unit.”

Some estimates claim running the air conditioning system can use between 0.2 to 0.4 litres of fuel per hour. 

KwikFit also confirmed that running the system may increase fuel usage by as much as 10 percent with the effects particularly noticeable on short journeys.

Breakdown experts and car insurance specialists at the RAC added that turning on the AC will have an impact. 

They commented: “Don’t use your air conditioning unless you really have to as it uses engine power and therefore increases fuel consumption.

“This goes for heat as well as cooling, so try to dress for the weather, even inside your car, if fuel efficiency is a big concern.”

PTA Garage Services revealed the impact of air conditioning could be slightly lower with fuel consumption increasing by between eight and 10 percent.
