Quad

4
Engines
(Codes

and

V6
Engine
(Code
N ) :
The 8th
digit
of
your
Vehicle
Identification
Number
(VIN)
shows
the
code
letter
for
your
engine. You
will
find
the
VIN at the
top
left
of
your
instrument
panel.
(See
the
I d e x
under
&hicle Identijkation
Number.)
Use regular
unleaded
gasoline
rated
at
87
octane or higher. It should
meet
specifications ASTM
D4814
in
the
U.S.
and
CGSB
3.5-92
in Canada.
These
fuels
should
have
the
proper
additives,
so
you
should
not
have
to
add
anything
to
the fuel.
In
the
U.S.
and Canada, it’s
easy to
be
sure you
get
the
right
kind
of
gasoline
(unleaded). You’ll
see “UNLEADED”
right
on
the
pump.
And
only
unleaded
nozzles
will
fit
into
your
vehicle’s
filler
neck.
Be sure the
posted
octane
is at least
87.
If
the
octane
is
less
than
87,
you
may get
a heavy
knocking
noise
when
you drive.
If
it’s
bad enough,
it
can damage your
engine.
