Engine oil viscosity, or thickness, has an effect on fuel economy and cold-weather operation
(starting and oil fl ow).
Low-viscosity engine oils can provide improved fuel economy and cold-weather
performance.
When choosing an oil, consider the temperature range your vehicle will operate in before
the next oil change.
Then select the recommended viscosity from the chart above.
CAUTION
  Using oils of viscosity besides those recommended for specifi c temperature ranges
could result in engine damage.
 
(SKYACTIV-D 2.2) SKYACTIV-D 2.2 uses specifi ed oil. Please confi rm the specifi cation in owner's
manual.If engine oil other than the specifi ed oil is used, the Diesel Particulate
Filter effective period of use will be shortened or the Diesel Particulate Filter may
be damaged.

NOTE
(MZR 1.6, SKYACTIV-G 1.5 and SKYACTIV-G 2.0)
 
 It is normal for all engines to consume engine oil under normal driving conditions.  Engine oil consumption may be as high as 0.8 L/1000 km (1 L/800 miles). This may
be as a result of evaporation, internal ventilation or burning of the lubricating oil in
the working engine. Oil consumption may be higher when the engine is new due to
the running-in process. Oil consumption is also dependant on engine speed and engine
load. Under extreme driving conditions, oil consumption may be higher.
(SKYACTIV-D 2.2)
 
 Whenever the engine oil is replaced, the vehicles engine control unit needs to be
reset as soon as possible. Otherwise the wrench indicator light or engine oil warning
light may turn on. To reset the engine control unit, consult an expert repairer, we
recommend an Authorised Mazda Repairer or refer to the vehicle engine control unit
reset procedure on page 6-28 .
  Inspect the engine oil level periodically. When inspecting the engine oil, if the engine
oil level is exceeds the “X” mark on the dipstick, replace the engine oil. This should
be done by an expert repairer, we recommend an Authorised Mazda Repairer. When
replacing the engine oil, inspect the oil level using the oil dipstick and refi ll so that the
engine oil level is within the range between Full to Low as shown in the fi gure.

This procedure is intended for vehicles with SKYACTIV-D 2.2 and vehicles with
SKYACTIV-G 1.5 or SKYACTIV-G 2.0 which the engine oil fl exible maintenance setting
is selected.
After replacing the engine oil, have a repair shop such as an Authorised Mazda Repairer
perform the initialization (engine oil data resetting) of the recorded value. If the value
recorded by the computer is not initialized, the wrench indicator light may not turn off or it
may turn on earlier than normal.
NOTE
The initialization (engine oil data resetting) of the recorded value can be performed using
the following procedure:
1. Switch the ignition OFF.
2. Switch the ignition ON with the selector pressed, and press and hold the selector for

When inspecting the engine oil level,
pull out the dipstick straight without
twisting. In addition, when inserting
the dipstick, always insert it without
twisting so that the “X” mark faces the
front of the vehicle.
5. Pull it out again and examine the level.
The level is normal if it is between
Low and Full.
If it is near or below Low, add enough
oil to bring the level to Full.
CAUTION
Do not overfi ll the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
