3800 Supercharged
(L67) Engine (OPTION)
Your Bonneville may have a 3800
Supercharged engine. The Supercharger is
a device which is designed to pump more
air into the engine than
it would normally
use. This air mixed
with fuel, creates
increased engine power. Since the
Supercharger is a pump and is driven
from an engine accessory drive belt,
increased pressure is available at all
driving conditions, The Powertrain Control
Module
(PCM),
works with a vacuum control to regulate
the increased pressure required during
specific driving conditions. When this
increased pressure or boost is
not desired,
such as during idling and light throttle
cruising, the excess air that the
’
Supercharger is pumping is routed,through
a bypass. All of these controls, working
together provide high performance
character and fuel efficiency
in the3800
V6 Supercharged engine.
The power steering pump uses a Remote
reservoir mounted on the throttle wd
cruise control cable bracket. See
“Maintenance Schedule”
in the Index for
when you should check the fluid:

See “Maintenance Schedule” in the Index
for when to check the accessory drive
belts and Supercharger oil level. Have
your dealer check the oil level in the
Supercharger.
Supercharger Oil
Unless you are technically qualified and
have the proper tools, you should let your
dealer or a qualified service center
perform this maintenance.
When to Check
Check oil level every 30,000 miles
(50 000 km) or every 36 months.
What Kind of Oil to Use
See “Recommended Fluids and
Lubricants” in the Index and use only the
recommended oil.
How to Check and Add Oil
Check oil only when the engine is cold.
Allow the engine to cool
2 to 3 hours after
running.

WIRING HARNESS SHIELD I
Remove the wiring harness shield.
Clean the area around the oil
fill plug
before removing it.
Remove the oil fill plug using a
3/16
Allen wrench.
The oil level is correct when
it just
reaches the bottom of the threads
of
the inspection hole.

CHECK OIL
LEVEL
Engine Oil
f the “CHECK OIL LEVEL” light on
he instrument panel comes on,
it means
‘ou need to check your engine oil level
ight away. For more information, see
CHECK OIL LEVEL” light
in the
ndex.
You should check your engine oil
:vel regularly; this is an added reminder.
t’s a good idea to check your engine oil
very time you get fuel. In order
to get an
ccurate reading, the oil must be warm
nd the vehicle must be on level ground. 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.
To Check, Engine Oil ., I’ .
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 lower, 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 section explains
what kind of oil to
use. For crankcase
capacity,
see “Capacities and
Specifications” in the Index.
, . .206
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.
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
Beginning midyear 1993, oils of the
proper quality for
your vehicle will be
identified with this new “starburst”
symbol. The “starburst” symbol indicates
that the oil has been certified by the
American Petroleum Institute (API), and is suitable for use
in your gasoline engine.
You should look for this on the front of
the
oil container, and use only oils that
display this new symbol.
You should also use the proper viscosity
oil for your vehicle,
as shown in the
following chart:
ProCarManuals.com

Recommended SAE Viscosity
Grade Engine Oils
For best fuel economy and cold starting,
select the lowest
SAE viscosity grade oil
for the expected temperature range.

IF NEITHER SAE 5W-30 NOR SAE 1OW-30

ABOVE 40 DEGREES
F (4 DEGREES C).
ANOTHER GRADE OIL NOT RECOMMENDED.
DO
NOT USE
SAE 1OW-40, SAE 2OW-50 OR
As shown in the chart, 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 (16°C) 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 1OW-40 or SAE
20W-50.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should
look for and use
oils containing the following three things:
SHor SG
“SH” or “SG’ must be on the oil
container, either by itself or combined
with other quality designations, such
as “SH/CD,” “SH,SG,CD,” “SG/CD,”
etc. These letters
show American
Petroleum Institute (API) levels of
quality.
SAE low-30
0 Energy Conserving I1
Oils with these words on the container
will help you save fuel.
These three things are usually included in
a doughnut shaped logo (symbol) on most
containers. If you cannot find oils
with
the “starburst” symbol, you should look
for oils
with the doughnut shaped symbol,
containing the three things noted
previously.

‘CONT.)
NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API SH or SG designation, you can
cause engine damage not covered
by
your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements fc
your vehicle.
Engine Oil Additives
I Don‘t add anything to your oil. Your
Pontiac dealer is ready
to advise if you
[hink something should be added.
When to Change Engine
Oil
See if any one of these is true for you:
0 Most trips are less than 4 miles
(6 km).
0 It’s below freezing outside and most
trips are less than
10 miles (16 km).
0 The engine is at low speed most of the
time (as
in door-to-door delivery, or
in stop-and-go traffic).
0 You tow a trailer often.
0 Most trips are through dusty places.
If any one of these is true for your
vehicle, then you need
to change your giJ
and filter every 3,000 miles (5 000 km) or
3 months -- whichever comes first. (See
“Change Oil Indicator”
in the Index.)
If none of them is true, change the oil
every
7,500 miles ( 12 500 km) or 12
months -- whichever comes first. Change
the filter at the first oil change and
at
every other oil change after that.
Engine Coolant Heater
(Engine Block Heater)
An engine coolant heater can be a big
help
if you have to park outside in very
cold weather,
0°F (-ISOC) or colder. If
your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer‘? Don’t let used oil stay
on
your skin for very long. Clean your skin
and nails
with soap and water, or a good
hand cleaner. Wash or properly throw
away clothing or rags containing used
engine oil. (See the manufacturer’s warnings about the use and disposal of oil
products.)
. . .208
ProCarManuals.com

Used oil can be a real threat to the
environment. If you change your own oil,
be sure to drain all free-flowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting
it in the trash,
pouring it on the ground, into sewers, or
into streams or bodies of water. Instead,
recycle
it by taking it to a place that
collects used oil.
If you have a proplem
properly disposing of your used oil; ask
your dealer, a service station or a local
recycling center for help.
Air Cleaner
Refer to the Maintenance Schedule to
determine when to replace the air filter.
See “Scheduled Maintenance Services” in
the Index.
NOTICE:
If the air cleaner is off, a backfire
can cause a damaging engine fire.
And, dirt can easily get into your
engine, which will damage it.
Always have the air cleaner in place
when you’re driving.
To Check or Replace (3800 Engine):
1. Unscrew the three wing screws in the
housing cover and pull back.
