engine oil OLDSMOBILE AURORA 1995 Owner's Manual

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 Aurora will:
0 Give freezing protection down to -34°F (-37°C)
0 Give boiling protection up to 262°F (128°C).
0 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 c.lt.crr~ wwtor (preferably
distilled) and one-half antifreeze that meets “GM
Specification 182S-M,” which won‘t damage aluminum
parts.
You call also use a recycled coolant conforming to
GM Specification 1825-M
with a complete coolant tlush
and refill. Use GM Engine Coolant Supplement (sealer)
with any cotnplete coolant flush and refill. If you use
this mixture, you don‘t need to add anything else.
A
special procedure is required for adding sealer; see the
ALI~o~~ Service Manual. (To order a service 1nanual. see
”Service Publications“
in the Index.)

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. A chime will sound if you
try to drive
with this warning light on. See “Brake
System Warning Light”
in the Index. What to
Add
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 removing it.
I NOTICE:
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.
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.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition. but also helps the
environment.
All recommended maintenance procedures
are important. Improper vehicle maintenance or the
relnoval of important components can significantly
affect the quality
of the air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level
of emissions from your vehicle. To help protect our
environment, and to help keep your vehicle
in good
condition, please lnaintain your vehicle properly.

I Maintenance Schedule I I
The services shown in this schedule up to 100,000 miles
( 166 000 km) should be performed after 100,000 miles
(1 66 000 km) at the same intervals.
Footnotes
f- The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not
nullify
the emission warranty or limit recall liability prior to the
completion
of vehicle useful life. We, however, urge that
all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.
* Your vehicle has an Engine Oil Life Monitor.
This monitor will show you when to change the oil
--
usually between 3,000 miles (5 000 km) and 7,500 miles
(1 2 500 km) since your last oil change. Under severe
conditions the indicator may come
on before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
without an oil change.
The system won’t detect dust in
the oil. So if you
drive
in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the Oil Life Monitor
when the oil has been changed. For more information,
see “Engine Oil Life Monitor” in the Index.
