and owners can make drastic fuel savings by pressing a button located in almost all modern vehicles, according to specialists at CarShop.

Modern cars are fitted with a whole host of technology to help motorists behind the wheel with tools even available to save fuel. 

Vehicles will tend to include an “eco” or “economy” mode which will help lower the strain on key components and therefore help save fuel.

The warning comes amid rising motoring costs with petrol and diesel fees soaring across the country in recent weeks. 

Eco mode buttons can usually be found on the car dashboard or as a setting in the onboard infotainment system.

Experts at CarShop explained: “Most modern cars are fitted with an ‘eco mode’ that reduces throttle responsiveness and engine power output, in turn using less fuel. 

“On automatic cars, it will also shift up earlier to keep the vehicle in the most economical gear which is calculated from the engine load. By using this mode you can save around five percent of fuel.”

Switching to Eco mode doesn’t reduce the speed of the vehicle but does turn down certain performance features to save fuel. 

Drivers should notice the car's acceleration is reduced with the throttle likely to become less reactive. 

According to motoring experts at Progressive, eco mode should only be used when motorists are travelling at a slower pace.

They stress the feature would typically be used for motorists travelling under 45mph making it ideal for leisurely commutes or driving around town. 

However, the experts have warned the tool should ideally not be used in certain situations such as when motorists are merging into traffic or driving on difficult roads. 

BookMyGarage, one of the leading comparison sites for service and repair quotes, also stressed switching to eco would “enhance vehicle’s fuel efficiency”. 

They also urged road users to manually turn off electrical equipment when it is not being used. 

This can include features such as the onboard air conditioning system which is known to use up some fuel.

Data from RAC Fuel Watch, the leading petrol and diesel comparison chart in the UK, shows petrol and diesel charges have skyrocketed in recent weeks. 

Fees were up around 9p per litre on average with unleaded petrol prices up from 140.45p per litre in January to 149.51p today.
