Quality requirements for fuel
Biodiesel (FAME)
Use of biodiesel
Scania uses the term biodiesel to refer to a re-
newable diesel made from greases or oils and
methanol. The biodiesel should conform to the
requirements of European standard EN 14214 or
Brazilian standard ANP-45. For biodiesel in ac-
cordance with EN 14214 or ANP-45, the generic
term FAME is frequently used.
Normal diesel in accordance with EN 590 can
contain up to 7% biodiesel from the diesel sup-
plier. There are grades of diesel that comply with
EN 590 but contain a higher mixture of biodies-
el.
Scania approves a mixture of up to 10% biodies-
el.
Storage of biodiesel
Biodiesel must not be stored for more than 6
months.
Biodiesel has a maximum storage life of
6 months from the date of production to the ex-
piry date. The fuel is affected by light, tempera-
ture, water, etc. during storage, which affects the
fuel characteristics and durability.
Biodiesel also has lower stability against oxida-
tion than diesel. This can result in a thickening of
the fuel and blocking of parts of the fuel system,
e.g. the fuel filter. Bacterial growth can occur
when fuel is stored in tanks under unfavourable
conditions. Avoid storage in barrels or auxiliary
tanks, except when fuel turnover rates are high.
Check tank cleanliness whenever refuelling
takes place.
If the engine has been refuelled with biodiesel,
and is stationary for a long period, condensation
water can form in the fuel tank resulting in bac-
terial growth.
