As
shown in the chart,
S A E 5W-30 is
best for
your
vehicle. However,
you
can
use
SAE
1OW-30
if it's going
to be
0°F
(-18OC) or above. These numbers on
an
oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as
SAE
2OW-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
46Starburst" 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.
Engine Oil Additives
Don't add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.

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, change the oil and filter every
7,500 miles (12 500
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.
