thereafter.
AC oil filters provide
excellent engine
protection.
See
your
Oldsmobile dealer
for
advice
on
the
frequency
of
oil
and
filter changes
under
unusual driving
conditions.
The
above
recommendations
apply
to
the
first change as well as
subsequent
oil
changes.
The
oil
change interval for
your
Oldsmobile engine
is
based
on
the
use
of
SE oils
and
quality
oil filters. Oil change
intervals longer
than
those
listed above will
seriously reduce engine life
and
may
affect
Oldsmobile's
obligation
under
the
provisions
of
the
New Vehicle Warranty.
A high
quality
SE
oil was installed
in
your
engine
at
the
factory.
It
is
not
necessary
to
change this factory-installed oi.1 prior
to
the
recommended
normal change period.
However, check
the
oil level more
frequently
during
the
break-in period since
higher
oil
consumption
is
normal until the
piston rings
become
seated.
NOTE:
Non-detergent
and
other
low
quality
oils are specifically
not
recommended.
Only
the
use
of
SE engine oils
and
proper
oil
and
filter
change intervals assure
you
of
continued
proper
lubrication
of
your
Oldsmobile engine.
RECOMMENDED
VISCOSITY-Select
the
proper
oil viscosity
from
the
following
chart:
-20 0
20
40
60
80
100
Temperature
Range
Anticipated
Before
Next
Oil
Change,
of.
The
proper
oil viscosity helps assure good
cold and
hot
starting.
NOTE
:
•
SAE
5W-20 oils are
not
recommended
for
sustained high-speed driving.
•
SAE
30
Jlils
may
be used
at
temperature
above
40
F.
•
SAE
5W-30 oils are recommended
for
all
seasons
in
vehicles
normally
operated in
Canada.
CHECKING
OIL
LEVEL-The
engine oil
should be maintained
at
the
proper
level.
The
best
time
to
check it
is
before
operating
the
engine or as
the
last step
in
a
fuel
stop.
This will allow
the
normal oil
accumulation
in
the
engine
to
drain
back
into
the
crankcase. To check
the
level,
remove
the
oi
I level gauge rod (dipstick),
wipe it clean and reinsert fu
lIy
it
for
an
accurate reading,
the
oil gauge · rod
is
marked
"FULL"
and
"ADD."
The
oil level
should be maintained
within
the
margin,
neither going above
the
"FULL"
line
nor
below
the
"ADD"
line.
Reseat
the
gauge rod firmly
after
taking
the
readi ng.
