Phil Cartwright, an inventor and RAC Patrol has invented an amazing device called the FuelSure which prevents misfuelling. It has never happedn to me myself but apparently more than 400 drivers every put petrol into their diesel vehicle by mistake. This translates into 150,000 misfuelling cases per year, 95 per cent are caused by drivers putting petrol into their diesel vehicles due to the wider diesel filler neck and narrower unleaded nozzle.
A very serious mistake indeed as it can cost between £300 upto £5000 to repair, not counting the environmental cost of disposal of this waste fuel, coupled with CO2 emissions generated by towing misfuelled vehicles.
FuelSure replaces the normal fuel cap and is easy to fit and can be used on over 80% of diesel cars and light commercial vehicles in the UK. The device costs £29.95 and is available from RAC Patrols and recovery specialists, as well as selected Halfords stores.
