The misfuelling prevention device

Excuse me, but can you spare a spare?

Calls by motorists for new cars to come equipped with full-size spare tyres are not fuelled by nostalgia according to many of the comments posted in response to an article from a well-respected daily publication – a common theme appears to be that a ‘real’ spare is required to keep them safely on the road.

Keeping drivers on the road is, of course, the objective of the Diesel Head Misfuel Prevention Device, designed to fit on to the fuel inlet pipe of many vehicles and stop motorists mistakenly fuelling their diesel cars with petrol.
