Buick 2002 Rendezvous - Manual (Page 361)

6-14
As in the chart shown previously, SAE 5W - 30 is best for
your vehicle. However, you can use SAE 10W - 30 if it’s
going to be 0
_F ( - 18
_C) or above. These numbers on an
oil container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W
- 50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines starburst
symbol. Failure to use the recommended oil can
result in engine damage not covered by
your warranty.
GM Goodwrench
R
oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls
below
- 20
_F ( - 29
_C), consider using 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
(GM Oil Life System
t)
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,but
on engine revolutions and engine operating temperature.
When the computer has calculated that the oil needs
changing, the GM Oil Life System
t will indicate that
a change is necessary. Change your oil as soon as it is
possible within the next two times you stop for fuel.
The mileage between oil and filter changes will vary
depending on how you drive your vehicle
-- usually
between 3,000 miles (5 000 km) and 10,000 miles
(16 000 km) since your last oil and filter change.
Under severe conditions, the system may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 10,000 miles (16 000 km) or 12 months
(whichever occurs first) without an oil change.
Remember to reset the CHANGE ENGINE OIL
message whenever the oil is changed. For the Oil Life
System to work properly, you must reset the system each
time the oil is changed.
