Engine Oil Additives
Don’t add anything to your
oil.
Your GM dealer
is
ready to advise if
you
think something should be added.
When to Change Engine
Oil
See if any one of these
is
true for
you:
0
Most trips are less than
4
miles
(6
km).
0
It’s below freezing outside and most trips are less than 10 miles (16 km).
0
The engine
is
at low speed most of the time
(as
in
door-to-door
delivery, or in stop-and-go traffic).
0
You
tow
a
trailer often.
0
Most trips are through dusty places.
The vehicle is frequently operated off-road.
If any
one
of
these is true for your vehicle, then
you
need to change your
oil
undfilter every
3,000
miles
(5
000
km)
or
3
months
-
whichever comes
first.
Light Duty Emissions:
If none of them
is
true, change the oil every
7,500
miles
(1
2
500
km) or
12 months
-
whichever comes first. Change the filter at the first
oil
change
and at every other
oil
change after that.
Heavy Duty
Emissions:
If none of them
is
true, change
the
oil every
6,000
miles
(1
0 000 km) or
12 months
-
whichever comes first. Change the filter at the first oil change
and at every other oil change after that
if
mileage determines when you
change your oil. If time determines when
you
change your oil, change the
filter each time you change your
oil.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be
a
big help if you have to park outside
in
very cold weather,
0”
F
(-1 8°C) or colder. If your vehicle has this option,
see “Engine Coolant Heater
”
in the Index.
What
to
Do
with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on
your skin for very long. Clean your skin and nails with soap and water,
or
a
good hand cleaner. Wash or properly throw away clothing
or
rags
containing used engine oil. (See the manufacturer’s warnings about
the
use
and disposal of
oil
products.)
