Engine Oil
It’s a good idea to check your engine oil
level every time you get fuel. In order to
get
an accurate reading, the oil must be
warm and the vehicle must be on level
ground. Turn
off the engine and give
the
oil a few minutes to drain back into
the oil pan. If
you don’t, the oil dipstick
might not show the actual level.
To Check Engine Oil:
Pull out the dipstick and clean it with a
paper towel
or cloth, then push it back
in all the way. Remove it again, keeping
the tip lower.

When to Add Oil:
If the
oil is at or below the ADD line,
then you’ll need to add some oil. But
you must use the right kind.
This
section explains what kind of oil to use.

engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper
operating range, your engine could
be damaged. For crankcase capacity, see the
Index under
Capacities and Specifications.

Just fill it enough to put the level
somewhere
in the proper operating
range. Push the dipstick all the way
back in when you’re through.
I What Kind of oil to Use
I
Look for Three Things:
SG
“SG” must be on the oil container,
either by itself
or combined with other
quality designations, such
as
“SG/CC,” “SG/CD,” “SF, SG, CC,”
etc. These letters show American
Petroleum Institute (API) levels
of
quality.
I NVIIUL:
If you use oils that don’t have the I
SG designation, you can cause
engine damage not covered by your

warranty. I

As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
However, you can use
SAE 1OW-30 if
it’s going to be
0°F (-18°C) or above.
These numbers on
an oil container
show its viscosity, or thickness.
Do not use other viscosity oils, such
as SAE 1OW-40 or SAE 2OW-50.

Engine Oil Additives
Don’t add anything to your oil. Your
Chevrolet 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:
Most trips are less than 4 miles
(6
lun).
It’s below freezing outside and most
trips are less than 10 miles (16
km).
The engine is at low speed most of the
time (as in door-to-door delivery, or in
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
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 comes first. If
none of them is true, change the oil
every
7,500 miles (12 500 km) or 12
months-whichever comes first.
Change the filter at the first oil change
and at every other oil change after that.
Engine Block Heater
An engine block heater can be a big
help
if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see the
Index under Engine Block Heater.
What to Do with Used Oil
CAUTION
Used engine oil contains
things that have caused skin
cancer in laboratory animals. 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.
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 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.
