Engine Oil
LOW
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Th,e engine
oil dipstick is the yellow loop near the back
of the engine.
If the LOW OIL light on the instrument panel comes on,
it means you need to check your engine oil level right
away.
For more information, see “Low Oil Light” in the
Index. You should check your engine oil level regularly;
this is an added reminder.

3800 Engine
3800 L36 (Code K) Oil Dipstick
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show
the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.

When to Add Oil
If the oil is at or below the ADD line, then you’ll
need to add some oil. But you must use the right
kind. This part explains what kind
of oil to use, For
crankcase capacity, see “Capacities and Specifications”
in the Index,
NOTICE:
Don’t add too much oil. If your engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper
operating
range, your engine could be damaged,
b-
Just fill it enough to put the level somewhere in the
proper operating range.
Push the dipstick all the way
back in when you’re through.
What Kind of 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
(BPI). Do not use any oil which
does not
carry this Starburst symbol.
If you change your own oil,
c the Starburst symbol on the
you have your oil changed
: for you, be sure the oil put ’ into your engine is

You should also use the proper viscosity oil for your
vehicle,

5.7L Engine
As shown in the chart, if you have the 5.7L 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,

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 2OW-50.

NOTICE:
Use only engine oil with the American Petroleum Institute Certified For Gasoline Engines
ccStarburst” symbol. Failure to use the
recommended 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 where the temperature falls below
-20°F (-29”C), consider using 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. Your Pontiac dealer is
ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance
schedule:
a
e
e
e
a
lvlost trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need
to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the
oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
