As
shown in the chart,
SAE
1OW-30
is
best for your
vehicle. However,
you
can use
SAE
5W-30
if it’s going
to be colder than
60°F
(16°C)
before your
next
oil
change. When it’s very cold, you should use
SAE
5W-30.
These numbers
on
an oil container show its
viscosity, or thickness.
Do
not
use other viscosity
oils,
such as
SAE
20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst”
symbol.
Failure to use the
recommended oil can result in engine damage not
covered
by
your
warranty.
GM Goodwrench@
oil
meets all the requirements for
your vehicle.
If you are in an area where the temperature falls
below
-20°F
(-29”C),
consider using either an
SAE
5W-30
synthetic oil or an SAE
OW-30
oil. Both
will provide easier cold starting and better protection
for your engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything
to
your
oil.
Your dealer
is
ready to
advise if
you
think something should be added.
When
to
Change Engine Oil
Your vehicle has an Oil Life Indicator. This feature
will let
you
know
when to change your oil and
filter
--
usually between
3,000
miles
(5
000
km)
and
7,500
miles (12
500
km)
since your last oil change.
Under severe conditions, the indicator may come on
before
3,000
miles
(5
000
km).
Never drive your vehicle
more than
7,500
miles
(12
500
km)
or
12
months
(whichever occurs first) without an oil change.
The system won’t dete.ct dust in the
oil.
So,
if you
drive in
a
dusty area, be sure to change your oil
every
3,000
miles
(5
000
krn)
or
sooner. Remember
to reset the Oil Life Indicator when the oil has been
changed. For more information, see “Oil Life Indicator”
in the Index.
