Engine Oil

CAUTION
Do not use either synthetic or semi-
synthetic motor oil. Otherwise engine
starting performance could worsen.
NOTE
Changing the engine oil should be done by
l
an Authorized Mazda Dealer.
The Mazda RX-8 requires regular checking
l
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.
