Engine Oil
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.
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.
