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
Maintenance Procedures:
Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedures. If you lack
sufficient knowledge and experience or the proper tools and equipment to do the work,
have it done by a qualified technician.
Running the Engine:
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.
Therefore, 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.
Electrical Fan and Engine Inspection:
Working near the electrical cooling fan when it is running is dangerous. You could be
hit by the fan and seriously injured. Turn off the ignition switch and make sure the
fan is not running before attempting to work near the electrical cooling fan.

Engine Oil
NOTE
The 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.
qRecommended 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.

qInspecting 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:

NOTE
lEach 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.
qChanging Engine Oil and Filter
Change engine oil and filter according to
Scheduled Maintenance (page 8-3).
Please act responsibly―protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information.
WARNING
Handling Used Engine Oil:
Continuous contact with used engine
oil is dangerous. It could cause skin
cancer. Always wash with soap and
water immediately after changing oil
and filter.

WARNING
Checking or Changing Engine Oil:
Hot engine oil is dangerous. If the
engine has been running, the engine
oil becomes very hot. You could be
seriously burned. Don't check or
change the engine oil when the engine
is hot.1. Remove the engine cover.
2. Warm up the engine for a few minutes
and turn it off. Remove the oil-filler
cap.
3. Remove the drain plug and drain the
oil into a suitable container.
4. Replace the plug tightly after the oil
has thoroughly drained.
5. Fill the engine with new oil to the F
mark on the dipstick.
6. Securely reinstall the oil-filler cap.

Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.
Engine Coolant
qInspecting Coolant Level
WARNING
Hot Engine:
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.
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS
HOT.
Electrical Fan and Engine
Inspection:
Working near the electrical cooling
fan when it is running is dangerous.
You could be hit by the fan and
seriously injured. Turn off the ignition
switch and make sure the fan is not
running before attempting to work
near the electrical cooling fan.
Cooling System Cap:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove the cooling
system cap when the engine and
radiator are hot.

LowOK
Use plain water if washer fluid is
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.

WARNING
Xenon Fusion Bulb Replacement:
Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Do not replace the xenon
fusion bulbs yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
Handling Halogen Bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries could
be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
qReplacing a Headlight Bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood and find the high and low
beam bulbs in the rear of the headlight
unit.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
Refer to Light Bulbs on page 8-32.
3. If you are changing the right headlight
bulb, start the engine, turn the steering
wheel all the way to the right, and turn
off engine. If you are changing the left
headlight bulb, turn the steering wheel
to the left.
4. Turn the center section of the plastic
retainer counterclockwise and remove
the retainers and partially peel back the
mudguard.
