GM Goodwrench@ oil
(in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer 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:
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.
The vehicle is frequently operated off-road.
If any
of these is true for your vehicle, then you need to change your oil and
filter
every 2,500 miles (4 000 km) or 3 months - whichever comes first.
If
none of them is true, change the oil and filter every 5,000 miles
(8 000 km) or 12 months - whichever comes first.
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, 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.

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 GM dealership Service Department.
If you do it yourself, be SLIK to follow all the instructions here, or you could
get a false reading on the dipstick.

Trailering Package
If your vehicle comes with the Trailering Package, there is also a load rating
which includes the weight
of the vehicle and the trailer it tows. This rating
is called the Gross Combination Weight Rating (GCWR).
When you weigh your trailer, be sure
to include the weight of everything
you put
in it. And, remember to figure the weight of the people inside as
part of your load.
Your dealer can help you determine your GCWR.
6-67
ProCarManuals.com

After you’ve loaded your vehicle and camper, drive to a weigh station and
weigh
on the front and rear wheels separately. This will tell you the loads on
your axles. The loads
on the front and rear axles shouldn’t be more than
either of the GAWRs. The total
of the axle loads should not be more than
the GVWR.
Open your driver’s door and look at
the CertificatiodTire label to find out
your CWAR and GVWR.
If
you’ve gone over your weight ratings, move or take out some things until
all the weights fall below the ratings. Of course, you should always tie down
any loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check the manufacturer’s
instructions.
If
you want more information on curb weights, cargo weights, cargo weight
rating and the correct center of gravity zone for your vehicle, your dealer
can help
you. Just ask for a copy of “Consumer Information, Truck-Camper
Loading.”
Trailer Recommendations
You must subtract your hitch loads from the CWR for your vehicle. Weigh
your vehicle with
the trailer hitch attached, so that you won’t go over the
GVWR or the GAWR.
You’ll get the best performance if you spread out the weight of your load
the right way, and if‘ you choose the correct hitch and trailer brakes.
For more information, see “Trailer Towing’’
in the Index.
Pickup Conversion To Chassis Cab
General Motors is aware that some vehicle owners may consider having the
pickup box removed and
a commercial or recreational body installed.
Before
you do so, first contact the GM Zone Office for your area for
information on such conversions. (See the “Warranty and Owner
Assistance” booklet for Zone Office.) Owners should be aware that, as
manufactured, there are differences between a chassis cab and a pickup with
the box removed which may affect vehicle safety. The components
necessary to adapt
the pickup to permit its safe use with a specialized body
should be installed by a body builder
in accordance with the information
available from
the Zone Office.

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or
leather with
a clean, damp cloth.
Your GM dealer has two
GM cleaners, a solvent-type spot lifter and a
foam-type powdered cleaner. They will clean normal spots and stains very
well.
Do not use them on vinyl or leather.
Here are some cleaning tips:
Always read the instructions on the cleaner label.
0 Clean up stains as soon as you can - before they set.
Use a clean cloth or sponge, and change to a clean area often. A soft
brush may be used if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area only. If you use
them, don’t saturate the stained area.
0 If a ring forms after spot cleaning, clean the entire area immediately or
it will
set.
Using Foam-Type CIeaner on Fabric
0 Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask surrounding trim
Mix Multi-Purpose Powdered Cleaner following the directions on the

lines.
container label.
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge to remove the
suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or cloth.
Then dry it immediately with a blow dryer or a heat lamp.
I NOTICE:
I Be careful with a hair dryer or heat lamp. You could scorch the I
fabric.
Wipe with a clean cloth.

Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better
with just water and mild soap.
If you need to use a solvent:
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.
0 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.)
Fabric Protection
Your vehicle has upholstery and trim carpet that has been treated with
Scotchgard
TM Fabric Protector, a 3M product. Scotchgard TM protects fabrics
by repelling oil and water, which are the carriers of most stains. Even with
this protection, you still need to clean your upholstery and trim carpet often
to keep
it looking new.
Further information on cleaning is available by calling 1-800-433-3296
(in Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Such as grease, oil, butter, margarine, shoe polish, coffee with cream,
chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.
0 Carefully scrape off excess stain.
Follow the solvent-type instructions described earlier.
0 Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be careful,
because
the cleaner will dissolve them and may cause them to spread.
Non-Greasy Stains
Such as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine,
vomit, urine and blood.
Carefully scrape off excess stain, then sponge the soiled area with cool
water.
0 If a stain remains, follow the foam-type instructions described earlier.

Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (mild
detergent) soaps. Don’t use cleaning agents that contain aci\
d or abrasives.
All cleaning agents should be flushed promptly and not allowed \
to dry on
the surface, or they could stain. Dry the finish with a soft, clean chamois o\
r
a
100% cotton towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your veh\
icle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get GM approved cleaning
products from your dealer. (See “Appearance Care and Materials” in the
Index.)
Your GM manufactured vehicle may have
a “basecoatklearcoat” paint
finish. The clearcoat gives more depth and gloss to the colored basecoat.
Always use waxes and polishes that
are non-abrasive and made for a
basecoatlclearcoat paint finish.
I NOTICE:
Machine compounding or aggressive polishing on a
basecoatklearcoat paint finish may dull the finish or leave swi\
rl
marks.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their l\
uster. Washing with water is all that is usually needed. However, you may use
GM Chrome
Polish on chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid damaging protective trim,
never use auto or chrome polish, steam or caustic soap to clean aluminum.
A coating of
wax, rubbed to high polish, is recommended for all bright
metal parts.
