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 provide easier

cold starting and better protection for the engine at

extremely low temperatures.

Engine Oil Additives

Do not add anything to the oil. The recommended oils

with the starburst symbol that meet GM Standard

GM6094M are all you 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 CHANGE ENGINE OIL SOON message

will come on. Change the 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 might not indicate that an oil change is

necessary for over a year. However, the engine oil and

ﬁlter must be changed at least once a year and at

this time the system must be reset. Your dealer/retailer

has trained service people who will perform this work

using genuine parts and reset the system. It is also

important to check the oil regularly and keep it at the

proper level.

If the system is ever reset accidentally, you must

change the 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 Engine Oil Life

System

The Engine Oil Life System calculates when to change

the engine oil and ﬁlter based on vehicle use.

Whenever the oil is changed, reset the system so it can

calculate when the next oil change is required. If a

situation occurs where you change the oil prior

to a CHANGE ENGINE OIL SOON message being

turned on, reset the system.
