2003 PONTIAC BONNEVILLE oil viscosity

Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection
if the SERVICE
ENGINE SOON light is on or not working properly.
Your vehicle will not pass this inspection
if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving.
If you have done this and your vehicle
still does not pass the inspection for lack of
OBD
system readiness, see your dealer or qualified service
center to prepare the vehicle for inspection.

Readings above the shaded warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the shaded warning zone may be caused
by a low oil level or another problem causing low
011
pressure. On vehicles with the systems monitor,
the
CHECK GAGES light will come on and a warning
chime will sound.

What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the starburst symbol.
This symbol indicates that the oil has been certified by
the American Petroleum Institute (API).
Do not use
any oil which does not carry this starburst symbol.
II If you choose to perform
the engine oil change
service yourself, be sure
the oil you use has
the starburst symbol on
the front of the oil
container.
If you have your
oil changed for you, be
sure the oil put into
your engine is American You
should also use the proper viscosity oil for your
vehicle, as shown in the viscosity chart.
SAE 1OW-30 is the viscosity grade recommended for
your vehicle. However, you can use SAE 5W-30
if
it’s going to be colder than 60°F (16°C) before your next
oil change. When it is very cold, colder than
0°F
(-18°C) you should use an SAE 5W-30 oil. These
numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity grade oils, such
as SAE 1OW-40 or SAE 20W-50 under any conditions.

oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ 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 OW-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.
