As shown in the chart, unless you have the 3800 engine,
SAE 5W-30 is best for your vehicle. However, you can
use
SAE 1OW-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.

As shown in the chart, if you have the 3800 engine, SAE
1OW-30 is best for your vehicle. However, you can use
SAE 5W-30 if it's going to be colder than 60°F (16OC)
before your next oil change. When it's very cold, you
should use SAE 5W-30. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W-50.

I NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not.
If your tires
don't have enough air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards. When
to Check
Check your tires once a month
or more.
Don't forget your compact spare tire. It should
be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell if your tires
are properly inflated
simply
by looking at them, Radial tires may look
properly inflated even when they're underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks
by keeping out dirt and moisture.

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody.
If these are
not removed, accelerated corrosion (rust) can occur
on the underbody parts such as fuel lines, frame, floor
pan and exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system
can do this
for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle.
This damage can
take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface.
Although
no defect in the paint job causes this, Pontiac
will repair, at
no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
