Fuel Tank and
Wi
ndshield/Headl ight Washer
Fillers
The filler
necks
for the fuel tank (B)
and the
windshield/headlight washer reservoir (A)
are
in the
left front fender under a flap. To
open
the flap,
pull
the
release button on the
left
side of
the instrument panel.
Be sure the fuel filler
is
closed
when
adding
cleaning
fluid or
water
to
the
washer reservoir.
To protect the paint finish when filling the luel
tank,
a
protective apron has been
provided.
Do not use
engine coolant anti-freeze or
any
other solution that can damage the
car paint,
in
the washer
reservoir.
Fuel tank capacity
Fuel tank capacity
is
listed under
"Filling
Capacities".
Never keep
on
driving until
the tank
is
completely empty.
Porsche does
not
recommend
the
use of
luel
additives.
lf
you
lose
your fuel filler cap,
replace
it
im-
medialely with
a
cap of the
same
design
to
reduce the possibility of a fire
in a
collision.
Fuel Recommendations
Your
Porsche
is
equipped
with
a
catalytic
converter and must use
UNLEADED FUEL
ONLY.
Carrera
214
Minimum octane rating
is
95
RON "Pre-
mium
unleaded
fuel" (90 CLC or
AKI). lf
unleaded premium fuel is
not
available,
a
built-in "Electronic
oktanerM Knock
Con-
trol"
makes
it
possible
lor
temporary
use
also
to
refuel
with
unleaded regular
fuel
with at
least 91
RON
(87 CLC or AKI).
Fed-
eral law
prohibits
use of
leaded
fuel
in this
vehicle.
The use
o1 UNLEADED FUEL ONLY is
criti-
cally important to the life of
the catalytic
con-
verter.
Deposits
Trom
leaded gasolines
will
ruin the converter and
make
it
ineffective
as
an emission control device.
Cars with a catalytic converter have a
smaller
fuel
tank
opening, and
gas
station
pumps
have smaller
nozzles.
This will prevent
ac-
cjdental pumping
of leaded fuel
into cars
with
a
catalytic
converter.
Unleaded
fuel
may
not be
available
outside
the
continental
U.S. and
Canada.
Therefore,
we
recommend
you
do not take your car
to
areas or
countries
where
unleaded
fuel
may
not be available.
Octane
ratings
Octane rating indicates a gasoline's ability
to
resist detonation. Therefore, buying the
cor-
rect
octane gas is
important
to prevent
engine
"damage".
The
RON octane rating
is
based
on the
re-
search
method.
The CLC (U.S. Cost
of Living
Council octane
rating)
or
AKI
(antiknock
index) octane rating
usually
displayed on
U.S.
gasoline pumps is calculated
as research
oc-
tane
number
plus
motor octane
number,
divided
by 2, that is
written
as:
R+M
2
or
75
