Habits may be hard to break but if they are costing you money it’s time for a rethink writes Geraldine Herbert 1) Driving in the wrong gear – To drive more efficiently don’t rev the engine and change up into a higher gear as soon as it is possible, correct use of gears can save you up to 15% of your fuel bill. 2) Ignoring warning lights – While many drivers don’t understand the most common dashboard warnings remember they are there to alert you that something is wrong and needs attention; ignore a warning light and you could end up stranded on the road or face expensive repairs later. 3) Sudden Braking- Constantly slamming on your brakes will wear out your discs and brake pads and increase the likelihood of brake failure. 4) Skimping on car maintenance- No one enjoys taking their car for a routine service, especially when often the car comes back feeling and looking the same as before.
