If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn
on and/or your vehicle
may fail
a smog-check test. If this occurs, return to your
authorized Geo dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may
not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his
fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
Geo dealer for service. To
provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system
to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan. Don’t reach through the
grille to release the underhood lever.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that
will burn onto a hot engine.
TO open the hood, first pull the release handle inside the
glove box.

B. Engine Coolant Reservoir

Before closing the hood, be sure all the filler caps
are on.
Then lift the hood to relieve pressure
on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop to its retainer. Then let the hood down
and close it firmly.
Engine Oil
If the engine oil pressure
light
on the instrument
panel comes on, it means
you need to check your
engine oil
level right away.
For more information, see “Engine Oil Pressure Light”
in the Index. You should check your engine oil level
regularly; this is an added reminder. It’s
a good idea
to check your engine oil every time you
get fuel. In order
to get an accurate reading, the oil must
be warm and
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.

Checking Engine Oil
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 down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need
to add at least one quart of oil. But you must use the
right kind.
This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications’’
in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that
shows the proper operating range,
your engine could be damaged.
Be sure to 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
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
I:
If you change your
own oil, be sure you
use oil that has the
Starburst symbol on
the front of the oil
container. If you have
your oil changed for
you, be sure the oil put
into your engine is
American Petroleum
I J
Institute certified for
gasoline engines.

You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst’’ symbol. Failure to use the
recommended oil can result in engine damage not
covered
by your warranty.
GM Goodwrench’ oil meets all the requirements for
your vehicle.
If you are
in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your Geo dealer is ready
to advise if you think something
should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or
use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. 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
occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change oil and filter every
7,500 miles (12 500 km) or 7.5 months -- whichever
occurs first. Driving a vehicle with a
fully warmed
engine under highway conditions causes engine oil to
break down slower.

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. Wdsh 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.
