Recommended Oil

Oil container labels provide important 
information.

The quality designation 

SL

 or 

ILSAC

 

must be on the label.

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 
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.
