Quality requirements for fuel
Biodiesel (FAME)
Use of biodiesel
Engine types DC16 084A and DC16 091A are
approved for used with biofuel in accordance
with ASTM D7467 (up to 20% mixture of bio-
diesel).
For other engines, a maximum of 10% mixture
of biodiesel should be used.
Note that reduction of maintenance intervals ap-
plies for use of more than 10% 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.
Maintenance interval
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
The viscosity grade of the engine oil should be
xW-40. xW-30 grade oils are unsuitable due to
the fuel dilution effect.
The engine oil level must be checked regularly.
If the oil level exceeds the maximum level, the
oil must be changed.
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. Biodiesel is affected by light, temper-
ature, water, etc. during storage, which affects
the characteristics and durability of the biodiesel.
Biodiesel also has lower stability against oxida-
tion than diesel. This can result in a thickening of
the biodiesel and blocking of parts of the fuel
system, e.g. the fuel filter. Bacterial growth can
occur when biodiesel is stored in a tank in unfa-
vourable conditions. Avoid storage in barrels or
auxiliary tanks, except when fuel turnover rates
are high. Check tank cleanliness whenever refu-
elling 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.
