Recommended Oil
Oil container labels provide important
information.
The quality designation SL
or ILSAC

must be on the label.Engine oil viscosity, or thickness, has an
effect on fuel economy and cold-weather
operation (starting and oil flow).
Low-viscosity engine oils can provide
improved fuel economy and cold-weather
performance.
But high-temperature weather conditions
require higher-viscosity engine oils for
satisfactory lubrication.
When choosing an oil, consider the
temperature range your vehicle will
operate in before the next oil change.
Then select the recommended viscosity
from this chart.
Energy conserving oils are recommended.
A chief contribution they make to fuel
economy is reducing the amount of fuel
necessary to overcome engine friction.
Engine Oil
NOTE
The Mazda RX-8 requires regular
inspection 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.
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.
Inspect the level when refueling.
FORGASOLINEENGINES
(ILSAC)
Using oils of viscosity besides those
recommended for specific temperature
ranges could result in engine damage.

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 5 minutes for the
oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.
5. 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.
The distance between L and F on the
dipstick represents the following:


Changing 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.
Changing engine oil
Don’t add engine oil over F. This may
cause engine damage.

CAUTION
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.
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 replace the oil-filler cap.
7. Start the engine and inspect around the
drain plug for leaks.8. Turn it off and wait 5 minutes for the
oil to return to the oil pan.
Check the oil level and fill to the F mark if
necessary.

Inspecting Coolant Level
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.
Do not overfill.

If new coolant is required frequently,
consult an Authorized Mazda Dealer.Engine Coolant
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.
WARNING
Radiator coolant will damage paint.
Rinse it off quickly.

Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
For mixture percentage:To change coolant
1. Remove the cooling system cap.
2. Only when the engine is cool, loosen
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant. •Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant’s effectiveness.
•Don’t add only water. Always add a
proper coolant mixture.
•The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
•DO NOT USE alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
•Don’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

CAUTIONRemoving the Cooling System Cap:
Removing the cooling system cap or
drain plug while the engine is
running or hot is dangerous. This
might lead to cooling system and
engine damage and could result in
serious injury from escaping hot
coolant or steam. Turn off the engine
and wait until it’s cool. Even then, be
very careful when removing the cap
or drain plug. Wrap a thick cloth
around it and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you’re sure all the pressure is
gone, press down on the cap — still
using a cloth — turn the cap, and
remove it.

3. With the drain plug loose but not fully
removed, flush out the system with
running water.
4. Drain the system completely and
retighten the plug. Add as much
ethylene-glycol-based coolant and
water as necessary to provide freezing
and corrosion protection.
5. In extremely cold climates, add the
amount recommended in the coolant
manufacturer’s instructions.
6. Reinstall the cooling system cap.
7. Run the engine at idle for about
10 minutes, then turn it off. If the
coolant level warning light comes on
during this time, turn the engine off.
After turning off the engine, inspect
the drain plug and the water hoses for
leaks.
8. After the engine has cooled, remove
the cooling system cap and inspect the
coolant level. If it’s low, repeat steps 5
to 7.

Inspecting 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.
NOTE
Because this procedure requires
technical expertise, we recommend
that it be done by an Authorized
Mazda Dealer.

Adding Brake/Clutch Fluid
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.

Inspecting Automatic
Transmission Fluid Level
The automatic transmission fluid level
should be inspected regularly. Measure it
as described below.
The volume of fluid changes with the
temperature. Fluid must be checked at idle
without driving at normal operating
temperature.
1. Park on a level surface and set the
parking brake firmly.
2. Idle the engine about two minutes.
Push down on the brake pedal.
3. Move the shift lever through all ranges
and set it at P.
Spilled Brake Fluid:
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. Be careful not to
spill brake fluid on yourself or on the
engine.
Low Brake/Clutch Fluid Levels:
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 you find a low fluid
level, have the brakes and clutch
inspected.
•Brake and clutch fluid will damage
painted surfaces. If brake or clutch
fluid does get on a painted surface,
wipe it off immediately.
•
Using nonspecified brake and clutch
fluids (page 10-5) 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.
WARNING
CAUTION
Automatic Transmission
Fluid (ATF)
•Low fluid level causes transmission
slippage. Overfilling can cause
foaming, loss of fluid, and
transmission malfunction.
•Use specified fluid (page 10-5). A
nonspecified fluid could result in
transmission malfunction and
failure.
