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
IMPORTANT!
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 may result in a thickening
of the fuel and clogging of parts of the fuel sys
-
tem, e.g. the fuel filter. Bacterial growth can oc
-
cur when biodiesel is stored in a tank in
unfavourable conditions. Avoid storage in bar
-
rels 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.

Maintenance interval
IMPORTANT!
Make sure that maintenance intervals are differ
-
ent when operating on diesel or biodiesel.
With a greater mixture of biodiesel than 10%, the
renewal intervals for the following are halved:
•
Fuel filter.
•
Oil filter.
•
Engine oil.
