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, 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.
If the light flashes continuously
If the warning light continues to flash, do
not drive at high speeds, drive the vehicle
at low engine rpm, and have an
Authorized Mazda Dealer inspect the
system.
NOTE
If the engine is turned off while the oil level
indicator is flashing due to a system
malfunction, it may take a few minutes until the
indicator starts flashing again after the engine
is started.
qEngine Coolant Level Warning Light
This warning light indicates low engine
coolant level.If the light illuminates while driving:
1. Drive to the side of the road and park
off the right-of-way.
2. Turn off the engine and inspect the
engine coolant level (page 8-14). If it's
low, add engine coolant.
3. Check the light.
If the light remains illuminated even after
you add engine coolant, have your vehicle
towed to an Authorized Mazda Dealer.
CAUTION
Don't run the engine if the engine
coolant level is low. It could result in
extensive engine damage.
qCheck Engine Light
This indicator light illuminates when the
ignition switch is turned to the ON
position and turns off when the engine is
started.
If this light illuminates while driving, the
vehicle may have a problem. It is
important to note the driving conditions
when the light illuminated and consult an
Authorized Mazda Dealer.
The check engine light may illuminate in
the following cases:
lThe fuel tank level being very low or
approaching empty.
lThe engine's electrical system has a
problem.

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.

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 service 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.
The level is normal if it is between
Low and Full.
If it is near or below Low, add enough
oil to bring the level to Full.
CAUTION
Do not add engine oil over Full. This
may cause engine damage.
The distance between Low and Full on the
dipstick represents the following:
