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

Do not add anything to your oil. The recommended oils

with the starburst symbol that meet GM Standard

GM6094M are all you will need for good performance

and engine protection.

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 dealer has GM-trained people

who will perform this work using genuine GM 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.
