1995 OLDSMOBILE SILHOUETTE engine oil

Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer
is ready
to advise if you think something should be
added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 5 to 10 miles (8 to 16 krn).
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.
0 You frequently tow a trailer or use a carrier 011 top of
your vehicle.
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 comes first.
If none
of them is true, change the oil and filter every
7,500 miles (12 500 km) or I2 months -- whichever
comes first.
Engine Coolant Heater (Option)
An engine coolant heater can be a big help if you have
to park outside
in very cold weather, 0°F (- 18OC) 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.)
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 or by 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 problem properly disposing of your used oil,
ask your retailer, a service station or a local recycling
center for help.

Automatic Transaxle Fluid
When to Check and Change
The automatic transaxle fluid dipstick for the 3.1 L V6
engine is located near the center of the engine
compartment, to the left
of the windshield washer fluid
reservoir. The dipstick for
the 3800 V6 engine is located
toward the back
of the engine Compartment, near the
center. The dipstick handle (for both engines) has
a
bright, red loop design for easier identification.
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services”
in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Oldsmobile retailer
Service Department.
If
you do it yourself, be sure to follow all the
instructions here, or
you could get a false reading on the
dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get
an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F
to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C).
If it’s colder than 50°F (lO°C), you may have
to drive longer.

Engine Coolant
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating”
in the
Index.
The proper coolant for your Oldsmobile
will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 128 ” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled)
and one-half antifreeze that meets “GM
Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture,
you don’t need to add anything else.
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged.
The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.

should have your brake system fixed, since a leak means
that sooner or later your brakes won’t work well, or
won’t work at all.
So, it isn’t a good idea to “top off’
your brake fluid. Adding brake fluid won’t correct a
leak. If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake
linings. You should add (or remove) brake fluid, as
necessary, only when work is done on the brake
hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.
~~
~~~ ~~~ ~
What to Add
The brake fluid reservoir is located to the left of the
windshield washer fluid reservoir, at the back of the
engine compartment.
When you
do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removin,g it.
-
NOTICE:
0 Don’t let someone put in the wrong kind of
fluid. For example, just a few drops of
mineral-based oil, such
as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
0 Brake fluid can damage paint, so be careful
not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.
