1993 BUICK ROADMASTER oil

It’s below freezing outside and most trips are less:
than
10 miles (16 km).
. The engine is -at low .speed most of the time (as in
door
tp door delivery, or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
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 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 Block Heater: An engine block heater can be a
big help if-you have
to park outside in very cold
weather,
-20 * F (-29 C] or .colder. If your vehicle has
this option, see
“Engine Block Heater” in the Index.
What to Do with Used Oil:
Used engine oil contains things that have
caused skin cancer in laboratory animals.

Used oil can be a real threat to the environment. If you
change your
own oil, be sure to drain all free-flowing oil
Erom the filter before disposal. Don’t ever dispose of oil
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 dealer, a
service station or
a local recycling center for help.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your auiomatic transmission 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
a Buick,dealership 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. Wait
at least
30 minutes before checking the
transmission fluid level
if you have been driving:
0 When outside temperatures are above. 90 F ‘(32 C);
0 At high speed for quite a while. I
In heavy traffic - &specially 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 check transmission fluid hot: Get the vehicle ‘warmed
up
by driving about 15 miles (24 krn) when outside
temperatures are above
50 F (1 0 C). If it’s colder than
50 F ( 10 C), drive the vehicle in “D” (3rd Gear) until
the engine temperature gage moves and then remains
steady for ten minutes. Then follow the hot check
procedures.
To check transmission fluid cold: A cold check is made
after the vehicle has been sitting for
8 hours or more
with the engine
off and is used only as a reference. Let
the engine run at idle for
5 minutes if outside
temperatures are
50 F (10 C) or more. If ‘it’s colder
than
50 OF (10 * C), you may have to idle the engine
longer.
A hot check must €0110~ when fluid is added

er to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. Wi’th
plain water or the wrong mix, your engine could
get
too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or others could be burned. Use a
50/50 mix of
clean water and a proper antifreeze.

Using Solvent-Type Cleaner on
Fabric
First, see if you have to use solvent-type cleaner at all.
Some sp-ots and stains will clean
off better with just
water and mild soap.
If you need to use it, then:

0
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very. little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at the outside
of
the stain, “feathering” toward the center. Keep changing to a clean section of the cloth.
When you clean a stain from fabric, immediately dry
the area with an air hose; hair dryer, or heat lamp to
help prevent a cleaning ring. (See the previous
NOTICE.)

Aluminum Wheels
If your Buick has these, don’t use chrome polish on
them.
Use wax after you clean them. Also, don’t use
abrasive cleaners or cleaning brushps on them - you
could damaee the proutive caating.
Your Buick dealer has a
GM White Sidewall Tire
Cleaner. You can use
a stiff brush with it.
Weatherstrips
These are places where glass-or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not squeak. Apply silicone grease with
a
clean cloth at least every si%. mmtk. .-
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish if they remain -on painted
surfaces. Use cleaners that are marked safe for painted
surfaces for these stains..

Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties. See
your Buick dealer for details.
Introduction
A Word About Maintenance
We at General Motors want to help, you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times’ a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work,
to do errands or in many other
ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than
you will
find
in the schedules in this part. So please read this part
and note how you drive. If you have any questions
on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners thoose to
have their maintenance work done. Your dealer can be
relied upon to use proper parts and practices.
