No more misfuels with flap alarm

Pouring petrol into an oil-burning car can cause havoc – but not if you use Halfords’ Think Diesel. It’s a light-sensitive device that goes inside your filler flap. When you open the flap, a recorded voice says: “Stop, diesel, remember, diesel.” For cars with an internal flap release, the instruction is repeated so you don’t forget. The universal device fixes in place using an adhesive pad.
