Pontiac 2006 Torrent - Manual (Page 252)

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 meet GM Standard GM6094M
are all you will 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 light will come on. Change your 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 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.
