Quality requirements for fuel
Biodiesel (FAME)
Use of biodiesel
For engines with SCR systems, a maximum of
10% mixture of biodiesel should be used.
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 up to a 10% mixture of biodies-
el for all engines.
For PDE engines, Scania approves the use of up
to 100% biodiesel in accordance with EN 14214
or ANP-45. However, this does not apply to en-
gines with an SCR system, for which only a 10%
mixture is permitted.
The viscosity grade of the engine oil should be
xW-40. xW-30 grade oils are unsuitable due to
the fuel dilution effect.
Check the engine oil level regularly. If the oil
level exceeds the maximum level, the oil must be
changed. Check the cause if the oil level exceeds
the maximum level and contact your nearest Sca-
nia workshop if you suspect a fault.
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.
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 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.
