Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
might 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.
Cold Temperature Operation
For Vehicles With the 2.2L L4 Engine
If in an area of extreme cold, where the temperature
falls below
−
20°F (
−
29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at extremely low
temperatures. Always use an oil that meets the required
specification, GM6094M. See “What Kind of Engine
Oil to Use” for more information.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM standards are
all that is needed for good performance and engine
protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has the Engine Oil Life System, a computer
system that indicates 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 is
indicated can vary considerably. For the oil life system
to work properly, the system must be reset every time
the oil is changed.
