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.

Using oils of viscosity besides those
recommended for specific temperature
ranges could result in engine damage.
