Drivers have been urged to take advantage of a fuel saving measure which could help reduce bills. According to experts, drivers could use a sat nav system trick to help them cut down on fuel costs. The trick involves using a Google Maps feature which is free to download on phones or via built-in systems. The fuel-saving tactic comes as the price of petrol and diesel still remains unaffordable high with drivers paying an average of 147.88p per litre for petrol and 153.58p a litre for diesel, although slightly less than in April.
