Checking Engine Oil
It is a good idea to check the engine oil 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.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 242
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull 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 down
and check the level.

When to Add Engine Oil
If the oil is below the MIN (minimum) mark, you
will need to add at least one quart/liter of oil.
But you must use the right kind. This section
explains what kind of oil to use. For engine
oil crankcase capacity, seeCapacities and
Specications on page 331.
Notice:Do not add too much oil. If the
engine has so much oil that the oil level
gets above the upper mark that shows the
proper operating range, the engine could
be damaged.SeeEngine Compartment Overview on page 242
for the location of the engine oil ll cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range.
Push the dipstick all the way back in when
you are through.

What Kind of Engine Oil to Use
For Vehicles With the 2.0L L4 Engine
Look for two things:
GM4718M
Your vehicle’s engine requires a special oil
meeting GM Standard GM4718M, such as
Mobil 1
®or equivalent. Oils meeting this
standard may be identied as synthetic.However, not all synthetic oils will meet this
GM standard. You should look for and use only
an oil that meets GM Standard GM4718M.
Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30
is best for your vehicle.
These numbers on an oil container show
its viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
also have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certied by the
American Petroleum
Institute (API).
You should look for this on the oil container, and
use only those oils that are identied as meeting
GM Standard GM4718M and have the starburst
symbol on the front of the oil container.
247
ProCarManuals.com

Your vehicle’s engine is lled at the factory with
a synthetic oil which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to
maintain engine oil level, oil meeting GM
Standard GM4718M may not be available.
You can add substitute oil designated SAE 5W-30
with the starburst symbol at all temperatures.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.For Vehicles With the 2.4L L4 Engine
Look for two things:
GM6094M
Your vehicle’s engine requires oil meeting
GM Standard GM6094M. You should look for
and use only an oil that meets GM Standard
GM6094M.

and have the starburst symbol on the front of
the oil container.Notice:Use only engine oil identied as
meeting GM Standard GM6094M and showing
the American Petroleum Institute Certied
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 of extreme cold, where
the temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for
good performance and engine protection.

Engine Oil Life System
When to Change Engine Oil
Your vehicle has the Engine Oil Life System,
a computer system that lets you know when to
change the engine oil and lter. This is based
on engine revolutions and engine temperature, and
not on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated
can vary considerably. For the oil life system
to work properly, you must reset the system every
time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL SOON message
will come on. SeeDIC Warnings and Messages
on page 147. Change the oil as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the oil life system may not indicate that an oil
change is necessary for over a year. However, the
engine oil and lter must be changed at least once
a year and at this time the system must be reset.Your retailer has trained service people who will
perform this work using genuine Saturn parts and
reset the system. It is also important to check your
oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since
the last oil change. Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System calculates when
to change your engine oil and lter based
on vehicle use. Anytime your oil is changed, reset
the system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a CHANGE OIL SOON
message being turned on, reset the system.
