WARNING
Do not perform maintenance work if you lack suf¿ cient knowledge and experience
or the proper tools and equipment to do the work. Have maintenance work done by a
quali¿ ed technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedures.

If you must run the engine while working under the bonnet, make certain that you
remove all jewellery (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly:
Working under the bonnet with the engine running is dangerous. It becomes even more
dangerous when you wear jewellery or loose clothing.
Either can become entangled in moving parts and result in injury.

Pull over to a safe location, then switch the ignition off and make sure the fan is
not running before attempting to work near the cooling fan:
Working near the cooling fan when it is running is dangerous. The fan could continue
running inde¿ nitely even if the engine has stopped and the engine compartment
temperature is high. You could be hit by the fan and seriously injured.

Do not leave items in the engine compartment:
After you have ¿ nished checking or doing servicing in the engine compartment, do not
forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a ¿ re
leading to an unexpected accident.

Engine Oil
NOTE
Changing the engine oil should be done by an expert repairer, we recommend an
Authorised Mazda Repairer.
Recommended Oil
In order to keep the maintenance interval (page 6-3 ) and to protect the engine from
damage caused by poor lubrication, it is vitally important to make use of engine oil with
the correct speci¿ cation. Do not use oils which do not meet the following speci¿ cations or
requirements. Use of unsuitable oil may lead to engine damage which is not covered by the
Mazda Warranty.

Engine oil viscosity, or thickness, has an effect on fuel economy and cold-weather operation
(starting and oil À ow).
Low-viscosity engine oils can provide improved fuel economy and cold-weather
performance.

6–24
Maintenance and Care
Owner Maintenance
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.
CAUTION
  Using oils of viscosity besides those recommended for speci¿ c temperature ranges
could result in engine damage.
 
 (SKYACTIV-D 1.5)  SKYACTIV-D 1.5 uses speci¿ ed oil. Please con¿ rm the speci¿ cation in owner's
manual. If engine oil other than the speci¿ ed oil is used, the Diesel Particulate
Filter effective period of use will be shortened or the Diesel Particulate Filter may
be damaged.
NOTE

(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/1,000 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 1.5) 

 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 6-25 .
 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 re¿ ll so that the
engine oil level is within the range between MIN and MAX as shown in the ¿ gure.

Vehicle Engine Control Unit Reset Procedure
NOTE
This procedure is intended for vehicles with SKYACTIV-D 1.5 and vehicles with
SKYACTIV-G 2.0 which the engine oil À 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 about 5 seconds until the master warning light
À ashes.

3. After the master warning light
À ashes for several seconds, the initialization
is completed.

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to return to the sump.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.

NOTE
(SKYACTIV-D 1.5)
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 the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not over¿ 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.
7. Reinsert the dipstick fully.
