Hypermiling: Experts offer advice on saving petrol<\/h3>\n

Drivers across the UK have been warned by the RAC about a specific car feature that could destroy fuel economy. As motorists look towards winter with the cost of living raging, the last thing they need is to waste money on petrol and diesel.\u00a0<\/p>\n

The RAC urged drivers to use cruise control to save fuel. Cruise control is a common feature of most modern cars and can help massively with boosting the fuel economy of the vehicle.<\/p>\n

However, drivers are being warned that cruise control will only aid fuel efficiency when driving on a constant, flat surface.<\/p>\n

This is why it is usually best reserved for motorway driving. One of the best ways to save fuel is to drive at a constant speed, which is made easier with cruise control.<\/p>\n

Drivers who use cruise control on non-flat roads may experience problems as it would be slower to react to gradient changes.<\/p>\n

When reaching the brow of a hill, drivers would normally take their foot off the accelerator to maintain more of a constant speed when descending.<\/p>\n

<\/strong><\/p>\n

The technology will keep the power on for longer as it is unable to see the gradient change in front, which can lead to \u201cworse fuel consumption\u201d, the RAC states.<\/p>\n

The most fuel-efficient roads in the country are not quiet extra-urban dual carriageways or 20mph city streets, they are motorways.<\/p>\n

The RAC warned: “Cruise control only aids fuel economy when driving on a constant flat surface, hence why it is usually best reserved for motorway driving. One of the keys to saving fuel is driving at a constant speed, cruise control can do this effectively on flat surfaces, making your driving as fuel efficient as possible by negating unnecessary acceleration.<\/p>\n
