Engine Oil Additives
Do not add anything to your oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M for the 2.2L L4 engine or GM4718M
for the 2.0L L4 supercharged engine are all you will
need for good performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. 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 CHG OIL message will come on. See
Change Engine Oil Message on page 3-41 for more
information on this message. Change your 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,
your engine oil and filter 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 your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
