Owner Maintenance Precautions
Improper or incomplete service may result in problems. This section gives instructions only
for items that are easy to perform.
As explained in the Introduction (page 8-2), several procedures can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
For details, read the separate Mazda Warranty statement provided with the vehicle. If
you're unsure about any servicing or maintenance procedure, have it done by an
Authorized Mazda Dealer.
There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.
WARNING
Do not perform maintenance work if you lack sufficient knowledge and experience or
the proper tools and equipment to do the work. Have maintenance work done by a
qualified technician:Performing maintenance work on a vehicle is dangerous if not done properly. You
can be seriously injured while performing some maintenance procedures.
If you must run the engine while working under the hood, make certain that you
remove all jewelry (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly: Working under the hood with the engine running is dangerous. It becomes even
more dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.
Turn off the ignition switch and make sure the fan is not running before attempting
to work near the cooling fan: Working near the cooling fan when it is running is dangerous. The fan could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously injured.
NOTE
Once the engine coolant exceeds a preset temperature, an electrical cooling fan turns on. It will
continue running for about 10 minutes after the ignition switch is turned to off.

Engine Oil
CAUTION
Do not use either synthetic or semi-
synthetic motor oil. Otherwise engine
starting performance could worsen.
NOTE
lChanging the engine oil should be done by
an Authorized Mazda Dealer.
lThe Mazda RX-8 requires regular checking
of the engine oil level. The compact, high
performance RENESIS rotary engine in
your vehicle consumes a small amount of
engine oil due to its structural design. An
oil pump optimizes the amount of oil
injected to lubricate the rotor seals in the
combustion cycle. Although your vehicle is
equipped with an engine oil level warning
light and an engine oil pressure gauge, it is
best to keep the engine oil level in the range
between full and low by checking the oil
dipstick regularly. Mazda recommends
checking the oil level at every second fuel
filling. The oil consumption of the engine
depends on engine speed and engine load.
Under extreme driving conditions, oil
consumption can be higher.
q Recommended Oil
Use SAE 5W-20 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
U.S.A. and CANADA
(ILSAC)
Only use oils “Certified For Gasoline
Engines ”by the American Petroleum
Institute (API). An oil with this trademark
symbol conforms to the current engine
and emission system protection standards
and fuel economy requirements of the
International Lubricant Standardization
and Approval Committee (ILSAC),
comprised of U.S. and Japanese
automobile manufacturers.

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to return to the oil pan. 4. Remove the engine cover.
5. Pull out the dipstick, wipe it clean, and
reinsert it fully.
Full
Low
OK
6. Pull it out again and examine the level.
It's OK between L and F.
But if it's near or below L, add enough
oil to bring the level to F.
CAUTION
Don't add engine oil over F. This may
cause engine damage.
The distance between L and F on the
dipstick represents the following:

NOTElEach mark from the F mark equates to
about 0.5 L (US 0.5 qt, Imp 0.4 qt).
There are 3 marks between L and F.
lVerify that the engine cover is securely
installed.
Engine Coolant
qInspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become
very hot. You could be burned.
Carefully inspect the engine coolant
in the coolant reservoir, but do not
open it.
Turn off the ignition switch and
make sure the fan is not running before
attempting to work near the cooling
fan: Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove the cooling
system cap when the engine and
radiator are hot: When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.

NOTE
Once the engine coolant exceeds a preset
temperature, an electrical cooling fan turns
on. It will continue running for about 10
minutes after the ignition switch is turned to
off.
NOTE
Changing the coolant should be done by an
Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season ―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
If it's at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
CAUTION
Ø Radiator coolant will damage
paint.
Rinse it off quickly if spilled.
Ø Use only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.
Ø Don't add only water. Always add
a proper coolant mixture.
Ø The engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
Ø DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
Ø DO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
Ø Don't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.

NOTE
If the“FL22” mark is shown on or near the
cooling system cap, use FL22 type engine
coolant. If engine coolant other than FL22
type is used, the engine coolant must be
replaced earlier than the specified replacement
interval indicated in the scheduled
maintenance (page 8-3).
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
Brake/Clutch Fluid
qInspecting Brake/Clutch Fluid Level
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.

qAdding Brake/Clutch Fluid
WARNING
Be careful not to spill brake fluid on
yourself or on the engine:
Spilled brake fluid is dangerous. If it
gets in your eyes, they could be
seriously injured. If this happens,
immediately flush your eyes with
water and get medical attention.
Brake fluid spilled on a hot engine
could cause a fire.
If the brake/clutch fluid level is low,
have the brakes and clutch inspected: Low brake/clutch fluid levels are
dangerous. Low levels could signal
brake lining wear or a brake system
leak. Your brakes could fail and
cause an accident.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
Ø Brake and clutch fluid will
damage painted surfaces. If brake
or clutch fluid does get on a
painted surface, wash it off with
water immediately.
Ø Using nonspecified brake and
clutch fluids (page 10-4) will
damage the systems. Mixing
different fluids will also damage
them.
If the brake/clutch system
frequently requires new fluid,
consult an Authorized Mazda
Dealer.
Washer Fluid
qInspecting Washer Fluid Level
WARNING
Use only windshield washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the
windshield, affect your visibility, and
could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather: Operating your vehicle in
temperatures below 4 degrees C (40
degrees F) using washer fluid without
anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In
cold weather, always use washer
fluid with anti-freeze protection.
NOTE
State or local regulations may restrict the use
of volatile organic compounds (VOCs), which
are commonly used as anti-freeze agents in
washer fluid. A washer fluid with limited VOC
content should be used only if it provides
adequate freeze resistance for all regions and
climates in which the vehicle will be operated.

unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
