Protecting diesel fuel against freezing and additives
Different makes of diesel fuel are commercially available. The quality of the diesel fuel dif-
fers according to the period of use (winter or summer). The filterability limit temperature
(FLT) varies according to the type of diesel fuel used. At a temperature close to the filter-
ability threshold, paraffin crystals begin to form in diesel fuel and these block the fuel lines
and filters.
To improve its properties when cold, it is possible to add kerosene or petrol to the diesel fuel.
Outside winter, the addition of products lowering the viscosity of the diesel fuel is strictly
forbidden.
– For protection down to - 15 °C : use diesel fuel Class " E " (TLF - 15 ° C)
– For protection down to - 20 °C : use diesel fuel Class " E " + 20 % kerosene (or paraffin)
– For protection below - 25 °C : use diesel fuel Class " ARTIC 4 " (TLF - 44 ° C)
– a) For maximum efficiency, the additives should be mixed with the fuel at a temperature
above 0 °C.
– b) In France, do not exceed 30 % paraffin or kerosene (Customs regulations.
– c) In other countries, always limit paraffin or kerosene addition to 50 % maximum
(check National regulations.
– d) However, we recommend that at all times the percentage be kept to the minimum
necessary and that paraffin be used in preference to petrol.
Use only commercially available diesel fuel for automotive vehicles (to standard
EN 590.
The use of "biodiesel" (with rapeseed oil base) is authorized at a maximum rate
of 5% on condition that it meets the requirements of standard EN 590.
You are advised against using diesel fuel containing additives.
The use of diesel fuel containing additives might invalidate the vehicle warranty.
Storage of diesel fuel in drums or jerry cans might allow the ingress of impuri-
ties capable of causing fuel supply system malfunction. In such case, it is neces-
sary to filter the diesel fuel before pouring it into the fuel tank.
The use of "aquazole" is strictly forbidden.
