Owner Maintenance
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.
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 specific temperature ranges
could result in engine damage.
(SKYACTIV-D 1.8)
SKYACTIV-D 1.8 uses specified oil. Please confirm the specification in owner's
manual. If engine oil other than the specified 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, SKYACTIV-G 2.5, and SKYACTIV-X 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 1.8)
Inspect the engine oil level periodically. When inspecting the engine oil, if the

engine oil level exceeds the "X" mark on the dipstick, replace the engine oil.
When replacing the engine oil, inspect the oil level using the oil dipstick and refill
so that the engine oil level is within the range between MIN and MAX as shown in
the figure.
