Diesel drivers warned of dangers

People who drive vehicles which take diesel fuel have been warned of hidden dangers the cold weather may bring.

The Institute of Advanced Motorists (IAM) said that waxing may occur, which involves crystals forming within the fuel. These may cause damage to the fuel filter, which in turn could lead to a breakdown.

“If you drive a diesel vehicle, it pays to try and park in a garage or sheltered area and try to not to leave your vehicle standing unused for too long,” advised Neil Greig, IAM’s head of policy and research. He advised anyone who does have to take their car out to make sure it is parked downwind, so the back of vehicle is hit by the cold wind first.

It is likewise important for drivers to start the engine around ten minutes before they set off, which will help the heat from the engine warm both the pipes and filter. This is generally a problem which affects lorries, although cars and vans may also be impacted if temperatures are cold enough.

In Scotland last night (January 7th), temperatures below -20°C were recorded, suggesting waxing could be more of a danger than people first think.

Mr Greig continued: “Keep the fuel tank full and, if possible, fill it before arriving at home as this will prevent the build up of condensation on the inside walls of the tank, helping prevent water building up in the bottom of the tank.”

Drivers may be interested to know that some oil companies supply winter diesel which is designed to withstand temperatures of -15°C between October and March.

The IAM also revealed that petrol stations sell fuel which is protected down to this temperature, with some additives available to make it even more resilient. However, the organisation warns that this should be added before the fuel gets cold and not after, as it could affect the engine’s warranty.
