When to Change Engine Oil (GM Oil Life System) 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 Change Engine Oil light will come on. Change your oil as soon as possible within the next two times you stop for fuel. 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. How to Reset the Oil Life System The GM Oil Life System calculates when to change your engine oil and filter 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 Engine Oil light being turned on, reset the system. After changing the engine oil, reset the system by performing the following steps: 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal three times within five seconds. If the Change Engine Oil light is flashing, the system is reset. The light will flash for up to 30 seconds or until the ignition is turned off. If the light comes on again and stays on for 30 seconds at the next ignition cycle, it did not reset. You will need to reset the system again. 5-19

When to Change Engine Oil (GM Oil
Life System)
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 Change Engine Oil light will come on.
Change your oil as soon as possible within the next two
times you stop for fuel. 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.
How to Reset the Oil Life System
The GM Oil Life System calculates when to change your
engine oil and filter 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 Engine Oil light
being turned on, reset the system.
After changing the engine oil, reset the system by
performing the following steps:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal three
times within five seconds.
If the Change Engine Oil light is flashing, the
system is reset. The light will flash for up to
30 seconds or until the ignition is turned off.
If the light comes on again and stays on for 30 seconds
at the next ignition cycle, it did not reset. You will
need to reset the system again.
