Notice: Use only engine oil with the American

oil can result in engine damage not covered by
your warranty.

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 your engine
at extremely low temperatures.

Engine Oil Additives

Don’t add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.

When to Change Engine Oil (Vehicles
Without the GM Oil Life System)

If any one of these is true for you, use the short trip/city
maintenance schedule:

Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.

Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).

You frequently tow a trailer or use a carrier on top
of your vehicle.

The vehicle is used for delivery service, police, taxi
or other commercial application.

Driving under these conditions causes engine oil to
break down sooner. 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
occurs first.

If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months — whichever
occurs first. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil to
break down slower.

When to Change Engine Oil (Vehicles
with the GM Oil Life System)

If so equipped, 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.
