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.
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.

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:
Oil capacity
L (US qt, Imp qt) 1.7 (1.8, 1.5)
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.
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 the ignition switch off and
remove the key from the ignition
switch when inspecting the engine:
Working near the electrical cooling
fan when it is running is dangerous.
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.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
Full
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.
