Metro ''Fuelrite'' warning device for diesel vehicles

Thousands of motorists every year accidentally put petrol into their diesel vehicle - it can be a very expensive mistake to rectify!

This is a very simple and effective way of minimising the chances of it happening to you.

Simply attach this plastic disc under your fuel flap using the adhesive pad, in such a way that the word ''DIESEL'' hangs over the fuel filler cap - giving you a timely reminder every time you refuel

It has to be worth £1.99 to potentially avoid a huge bill if you have an absent minded moment at the filling station!
