dies el(FAME [fatty acidmethyl ester])
Merced es-Benz USAapproves theuse ofB5
for alldie sel engines withcommon raildire ct
injection (CDI)andBlue TEC. The
concentration ofbio -dies elin ULSD maybea
maximu mof up to5% byvolu me.
Pure bio-dies eland diesel fuel sthat have a
high erconcentration ofbio -dies el,e.g. B20,
can dama gethe fuel system andtheengine.
They aretherefore notapproved.
For further informa tion,please askthegas
station personnel.Thelabel onthe gas pump
must indicate clearlythat theB5bio-dies el
ble nd fulfillsthe ULSD standa rd.Ifthe label
is not clea r,do not refue lthe vehi cle.
Do not refue lyou rvehicle withfuels unless
they have been approved byMercedes- Benz.
Addit ivesingasoline One
ofthe main problems ofpoor fuelquality
is the formin gof deposits thatarecreat ed
during thegasoline combustionprocess .
Mercedes- Benzrecom mends thatyouuse
fuel brands thathave theadditives.
Deposit smay form ifyou usefuels without
additives overalonger period oftime. These
deposits aremost likely toform onthe inlet
valves andinthe combust ionchamber.
This could leadtoengin eproblems, e.g.:
R longer enginewarm-up phase
R uneven idle
R engin enoise
R misfirin g
R loss ofpower
Carbon deposits mayform ifthe availabili ty
of gasoline withrelevant additives is
insuffic ient(incert ainregions). Inthis case,
Mercedes- Benzrecom mends theuse of
additives thathave been approved for
Mercedes- Benzvehicles. Consult
anauthoriz edMercedes- BenzCent er
or go tothe Internet site
htt p:// www.mbusa.com (USAonly)foralist
of approved products.Comply withthe
inst ruct ions foruse onthe product label.
Do not mix other fueladditives withfuel. This
causes unnecessary costsand could damage
the engin e.
! Donot refuel withlow-grade fuelanddo
not use fuel additives thatarenot tested
and approved forMercedes- Benzvehicles.
Damage toor malfunct ionsofthe fuel
system mayother wiseoccur. DEF
