Note
-
Fuels con taining a high pe rcentage of etha-
no
l
such as ESQ and EBS may only be used in
vehicles with flexible fuel engines. Using
high ethanol fuel in veh icles not equ ipped
with flexib le fue
l
engines can cause severe
engine damage.
- Methanol fuels which do not meet these re-
quirements may cause corros ion and dam-
age to plast ic and rubber components in the
fuel system.
-
Do not use fuels that fail to meet the spec i-
fied criter ia in this chapter
.

If you are unable to determine whether or
not a particular fuel blend meets the spec i-
fications, ask your service station o

Ethanol fuel (Bio-ethanol)
Applies
to
vehicles: with flex ible fuel engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap.
Vehicles w ith flex ible fuel engines may be oper-
ated w ith b
io-et
hanol fuels such as EBS (85%
ethano
l
and 15% gasoline) or with un leaded gas-
oline (91 AKI/ROZ 95)
.
The ve hicle may a lso
be
operated with a mixtu re of these fuels.

Due to the chemica

composition of bio-ethanol
,
a certa in amount of fue

when driving short distances in very low temper-
atures
.
This fuel evaporates again when the en-
gine is warmed up.
