According to the latest data, the average price for a litre of petrol stands at 187.19p per litre, while diesel prices have fallen to 195.88p. With these high prices, many motorists are making use of fuel-saving techniques, as one simple button could help drivers improve their fuel economy.

By using cruise control and going a few miles under the speed limit, the vehicle will maximise fuel efficiency.
He said: “If you’re going a bit slower, and using the cruise control, the engine computer is automatically going to calculate the greatest fuel economy that you can get for those road speeds and tune the engine accordingly.
“The less speed and the less throttle you’re using, the better it’s going to be for your savings.
“Ballpark, you can probably expect anywhere from one percent to five percent increase [in mileage] by using cruise control, but every little bit helps.”
He acknowledges that the savings aren’t overwhelmingly large, but over the course of a long road, they can add up.
