During very cold weather some diesel-powered engines may experience difficulties with starting and initial running. These problems arise
from the formation of wax crystals, which block fuel filters and/or fuel lines. All diesel fuel contains wax. It is considered an important diesel
component because of its high cetane value (a measure of the fuel’s resistance to premature combustion). Normally the wax remains liquid
but when diesel fuel gets cold enough the wax starts to crystallize and solidify. If the temperature is sufficiently low, enough crystals will
form to block the fuel filter and/or fuel lines, resulting in the engine becoming difficult to start and run until the fuel temperature increases
sufficiently.
UK diesel is manufactured to the European standard BS EN 590 and the specification of the fuel supplied from refineries is changed during
winter months (Circa: 16th November to 15th March) in order to improve the cold weather performance properties of the fuel. The UK is in
a zone that specifies that diesel remains free of wax crystals down to -15
ﹾ C
entigrade (known as the cold filter plugging point test CFPP).
With sustained temperatures below this level, particularly in exposed areas or when a vehicle is left idle for several days, blocking of filters
and/or fuel lines may occur resulting in the engine becoming difficult to start and run until the fuel temperature increases sufficiently.
There are a number of practical measures that can be taken to avoid or reduce problems, including the following:
• It may be advisable to sit in the vehicle with engine running for several minutes before moving off in order to aid build up to working
temperature.
• If possible, park your vehicle in a garage overnight or in a more sheltered area near a building.
• Avoid parking the vehicle with the front facing into the wind.
• If it is impossible to move the vehicle due to snow, try to run the engine daily in order to maintain movement in the fuel system and
generate heat.
Under no circumstances should heat that involves a naked flame or other potential sources of ignition, be applied to any of the fuel system
components.
If you are aware that you will be operating your vehicle in conditions of circa: -10
ﹾ
Centigrade or below on a regular basis we recommend
the fitment of a fuel line heater. Your local Mitsubishi Motors dealership will be able to assist you with this.
