Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise
if
you
think something should be added.

to
Change Engine Oil
If any one
of
these is true for you, use the short tripkity

Most trips are less than
5
to
10
miles
(8
to
16
km).
This is particularly important when outside
temperatures are below freezing.
Most
trips include extensive idling (such as frequent
driving
in
stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow
a
trailer or use
a
carrier on top
of
your vehicle.
The vehicle
is
used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one
of
these is true for your
vehicle, then you need
to
change your oil and filter
every
3,000
miles
(5
000
km) or
3
months
--
whichever
occurs first.
If
none of
them is true,
use
the
long trip/highway
maintenance schedule. Change the oil and filter every
7,500
miles
(1
2
500
km)
or
12
months
--
whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
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.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring
it
on
the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you
have a problem properly disposing
of
your used oil,
ask your dealer, a service station or a local recycling
center for help.
