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, 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.

CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.
NOTE
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-34.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-34.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New treadTread wear indicator
Worn tread
You should replace the tire before the
band crosses the entire tread.NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. You should
replace the spare tire when you replace the
other road tires due to the aging of the spare
tire. The period in which the tire was
manufactured (both week and year) is
indicated by a 4-digit number.
Refer to The tire labeling on page 9-21.
qTemporary Spare Tire
Your Mazda is not equipped with a spare
tire. If you require a spare tire, consult an
Authorized Mazda Dealer.
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
NOTE
The temporary spare tire condition gradually
deteriorates even if it has not been used.
The temporary spare tire is easier to
handle because of its construction which
is lighter and smaller than a conventional
tire. This tire should be used only for an
emergency and only for a short distance.
Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2
kgf/cm
2or bar, 60 psi).

CAUTION
ØDo not use your temporary spare
tire rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage
both tire and rim.
ØThe temporary spare tire has a
tread life of less than 5,000 km
(3,000 miles). The tread life may
be shorter depending on driving
conditions.
ØThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator
appears, replace the tire with the
same type of temporary spare
(page 8-25).
NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can

qReplacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident.
CAUTION
ØA wrong-sized wheel may
adversely affect:
ØTire fit
ØWheel and bearing life
ØGround clearance
ØSnow-chain clearance
ØSpeedometer calibration
ØHeadlight aim
ØBumper height
ØTire Pressure Monitoring
System
ØLimited-Slip Differential System
Ø(With Tire Pressure Monitoring
System)
ØWhen replacing/repairing the
tires or wheels or both, have the
work done by an Authorized
Mazda Dealer, or the tire
pressure sensors may be
damaged.
ØThe wheels equipped on your
Mazda are specially designed
for installation of the tire
pressure sensors. Do not use
non-genuine wheels, otherwise
it may not be possible to install
the tire pressure sensors.
NOTE
Be sure to install the tire pressure sensors
whenever tires or wheels are replaced. Refer to
Tires and Wheels on page 5-34.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

WARNING
Do not replace the xenon fusion bulbs
yourself:
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. Consult an Authorized
Mazda Dealer when the replacement
is necessary.
Never touch the glass portion of a
halogen bulb with your bare hands and
always wear eye protection when
handling or working around the 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.
Always keep halogen bulbs out of the
reach of children:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb
or breaking it some other way.
qReplacing Exterior Light Bulbs
