One of the coldest winters in living memory is bringing particular problems to a new breed of diesel drivers, unfamiliar with different characteristics that this fuel has when compared to petrol. The Institute of Advanced Motorists (IAM) has issued a warning to diesel drivers urging them to be aware of problems caused by waxing, which is the formation of crystals in diesel fuel brought on by sub zero temperatures.  This can lead to fuel filter damage and subsequent engine problems. The advice from the IAM to avoid this is:

·    Where possible try to park in a garage or sheltered area.
·    If there is no shelter try to park with the back of the car facing into any wind.
·    Do not leave vehicles standing idle for too long in extreme cold.
·    Leave the car running for a few minutes before driving off.

A further problem can be caused by ice forming in a fuel tank. This comes from condensation within the tank and can be overcome by keeping the tank as full as possible before leaving overnight.
