Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
Your Mazda will perform best with fuel listed in the table.
Fuel Octane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
You may use a regular unleaded fuel with an Octane Rating from 87 to 90 (91 to 95 RON)
but this will slightly reduce performance.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
lUSE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
lYour vehicle can only use oxygenated fuels containing no more than 10% ethanol by
volume. Damage to your vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline contains any methanol. Stop using gasohol of any
kind if your vehicle engine is performing poorly.
lNever add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10%. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name“Gasohol”.
Vehicle damage and drivability problems resulting from the use of the following may not
be covered by the Mazda warranty.
lGasohol containing more than 10% ethanol.
lGasoline or gasohol containing methanol.
lLeaded fuel or leaded gasohol.

CAUTION
Don't try the starter for more than 10
seconds at a time. If the engine stalls or
fails to start, wait 10 seconds before
trying again. Otherwise, you may
damage the starter and drain the battery.
6. After starting the engine, let it idle for
about 10 seconds.
NOTE
lIn extremely cold weather, below
–18°C (0°F), or after the vehicle has
not been driven in several days, let
the engine warm up without
operating the accelerator.
lWhether the engine is cold or warm,
it should be started without use of
the accelerator.
lTo protect the engine, when the
engine coolant temperature is low,
the engine does not run at high
speeds. The fuel supply will be cut at
an rpm lower than the red zone.
Brake System
qFoot Brake
Your Mazda has power-assisted brakes
that adjust automatically through normal
use.
Should power-assist fail, you can stop by
applying greater force than normal to the
brake pedal. But the distance required to
stop will be greater than usual.
WARNING
Coasting with the Engine Off:
Continuing to coast when the engine
is stalled or turned off is dangerous.
Braking will require more effort, and
the brake's power-assist could be
depleted if you pump the brake. This
will cause longer stopping distances or
even an accident. Don't continue
coasting when the engine is stalled or
turned off, find a safe place to stop.
Riding the Brakes:
Driving with your foot continuously
on the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle
control and a serious accident. Avoid
continuous application of the brakes.
Shift to a lower gear when going down
steep hills.

qFuel Gauge
The fuel gauge shows approximately how
much fuel is in the tank. We recommend
keeping the tank over 1/4 full. When the
low fuel warning light illuminates or
when the needle is near E, refuel as soon
as possible.
Low fuel warning light
qEngine Oil Pressure Gauge
Engine oil pressure is normal when the
engine oil pressure gauge needle points
halfway between L and H with the engine
running.
If the needle on the gauge doesn't move
after starting the engine, follow steps 1
through 3.If the engine oil pressure gauge moves to
L (low) while you are driving, drive to the
side of the road and park off the right-of-
way. Set the parking brake. Then follow
steps 1 through 3.
1. Turn off the engine and inspect the
engine oil level (page 8-13). If it's low,
add oil.
2. Start the engine.
3. If the needle still doesn't move, have
your vehicle checked at an Authorized
Mazda Dealer.
CAUTION
Don't run the engine if the oil pressure
is low. It could result in extensive
engine damage.
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.

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 8-15). 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
If this light comes on while driving, the
vehicle may have a problem. It is
important to note the driving conditions
when the light came on and consult an
Authorized Mazda Dealer.
The check engine light may come on in
the following cases:
lThe fuel tank level being very low or
approaching empty.
lThe engine's electrical system has a
problem.
lThe emission control system has a
problem.
lThe fuel-filler cap is missing or not
tightened securely.
If the check engine light remains on or
flashes continuously, do not drive at high
speeds and consult an Authorized Mazda
Dealer as soon as possible.

A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
