1994 CHEVROLET TRACKER fuel

worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
What about gasoline
with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE
is “methyl tertiary-butyl ether.”
Fuel that is no more than
15% MTBE is
fine for your vehicle.
Ethanol
is ethyl or grain alcohol.
Properly-blended fuel that
is no more
than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than S% methanol
is bad for your vehicle. 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. And
even
at 5% or less, there must be
“cosolvents” and corrosion prevent-
ers
in this fuel to help avoid these
problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
additives
will help prevent deposits from
forming
in your engine and fuel system.
That helps keep your engine
in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part
for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors recommends
that you use gasolines
with these blending
materials, such as MTBE and ethanol. By
doing
so, you can help clean the air,
especially
in those parts of the country
that have high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General Motors
recommends that you use reformulated
gasoline.
By doing so, you can help clean
the air, especially
in those parts of the
country that have high ozone levels.
You should ask your service station
operators
if their gasolines contain deposit
control additives and oxygenates, and
if
they have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country
outside the
U.S. or Canada, unleaded fuel
may be hard to find.
Do not use leaded
gasoline. If you use even one tankful,
your emission controls won’t work well
or at all. With continuous use, spark plugs
can get fouled, the exhaust system can
corrode, and your engine oil can
deteriorate quickly. Your vehicle’s oxygen
sensor
will be damaged. All of that means
costly repairs that wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto
club, or contact a major oil company
that
does business in the country where you’ll
be driving.
You can also write us
at the following
address for advice. Just tell us where
you’re going and give your Vehicle
Identification Number
(VIN).

Filling Your Tank
The cap is behind a hinged door on the
right side of your vehicle.
I’o take off the cap, turn it slowly to the
left (counterclockwise).
Be careful not to spill gasoline. Clean
gasoline from painted surfaces as soon as
possible. See “Cleaning
the Outside of
Your Geo” in the Index.
When you put the cap back on,
turn it
to the right until you hear at least three
:licks.
NOTICE:
If you need a new cap, be sure to get
the right type.
Your dealer can get
one for you. If you get the wrong
type, it
may not fit or have proper
venting, and your fuel tank and
emissions system might be damaged.

Engine Oil
It’s a good idea to check your engine oil
level 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.
To Check 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 lower.

for the expected temperature range.

COLD
WEATHER
IF NEITHER SAE 5W-30 NOR SAE 1OW-30 GRADE OILS ARE AVAILABLE, SAE 30 GRADE
MAY BE USED AT TEMPERATURES ABOVE 40 DEGREES F (4 DEGREES C).
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRAOE OIL NOT RECOMMENDED.
As shown in the chart, SAE SW-30 is best
for your vehicle. However, you can use
SAE IOW-30 if it’s going to be 0°F
(-1 8°C) or above. These numbers on an
oil container show its viscosity, or
thickness.
Do not use other viscosity oils,
such
as SAE IOW-40 or SAE 2OW-SO.
If you cannot find oils with the new
“starburst” symbol on the front of the
container,
you should look for and use
oils containing the following three things:
Ski or SG
“SH” or “SG” must be on the oil
container, either
by itself or combined
with other quality designations, such
as
“SHKD,” “SH,SG,CD,” “SGKD,”
etc. These letters show American
Petroleum Institute (API) levels of
quality.
SAE SW-30
Energy Conserving I1
Oils with these words on the container
will help you save fuel.
These three things are usually included in
1 doughnut shaped logo (symbol) on most
Zontainers.
If you cannot find oils with the
“starburst” symbol, you should
look for
lils with the doughnut shaped symbol,
;.ontaining the three things noted above.
NOTICE:
If you use oils that do not have either
the “starburst” symbol or
an API SH
or SG designation, you can cause
engine damage not covered
by your
warranty.
3M Goodwrench” oil (in Canada, GM
Engine Oil) meets

Inflation - Tire Pressure
The Certificatioflire label which is on the driver’s door shows the correct inflation
pressures for your tires, when they’re cold. ‘Told” means your vehicle has been
sitting for at least three hours or driven no more than
a mile.
NOTICE:
Don’t let anyone tell you that underinflation PI: overinflation is all right. It’s not.
If your tires don’t have enough air (underinflation) you can get:
i Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation), you can get:
0 Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.
When to Check: Check your tires
once a month or more. Also, check the
tire pressure
of the spare tire.
How to Check: Use a good quality

Foreign Material
Calcium chloride and other salts, ice
melting agents, road oil and tar,
tree sap,
bad$ droppings, chemicals from industrial
chimneys, and other foreign matter can
damage your vehicle’s finish if they
remain on painted Surfaces. Use cldners
that
&e marked safe for painted surfaces
to remove foreign matter.
Finish Damage
Any stone chips, fractui-es or deep
scratches in the finish should be repaired
right away. Bare metal will corrode
quickly and may develop into a major
repair expense.
Minor chips and scratches can be repaired
with touch-up materials available from
YOU^ dealer or other service outlets.
Larger areas
of finish damage can be
corrected in your dealer’s body and paint
shop.
Underbody Maintenance
Chemicals used for ice and snow removal
and dust control can collect on the
underbody;
If these are not removed,
accelerated corrosion (rust) can occur on
the underbody parts such as fuel lines,
frame,
floor pan, and exhaust system even
though they have corrosion protection.
At least every spring, flush these
materials
.from the underbody with plain
water. Clean any areas where mud and
othef deb& can collect.
Dirt packed in
closed areas
of the frame should be
loosened before
being flushed. Your
dealer or an underbody vehicle washing
system can do this
for you.
Chemical Paint Spotting
Some weather and atmospheric conditions
can create
a chemical fallout. Airborne
pollutants can fall up~n and attack painted
surfaces on your vehicle.
This damage
can take two forms: blotchy,
ringlet-shaped discolorations, and small
irregulai dark spots etched into the paint
surface.
Although no defect in the paint job causes
this, Geo
will repair, at no charge to the
owner, the surfaces of new vehicles
damaged by this fallout condition within
12 months or 12,000 miles (20
000 km)
of purchase, whichever comes first.
