Drivers are being warned to stop filling up their tank once the pump clicks to a halt for the first time. At best motorists could be wasting money while at worst they could be causing their vehicle £500 of damage.
Graham Conway, managing director of UK leasing firm Select Car Leasing, said that although squeezing the fuel pump after the first click - known as 'topping off' - might seem worthwhile to round up to the nearest pound, it 'really isn't.' He explained: “That’s because it’s likely to still dispense some fuel that won’t end up in your tank.
"If you ignore the first click you could be filling past the top of the fuel tank port, and that extra fuel will end up running into the small drain under the entry and onto the ground beneath your vehicle. On some pumps the extra fuel may be sucked back into the pipe, as seen in Manchester Evening News.
