Vehicle Care
Specification
Use and ask for licensed engine oils
with the dexos1
®
approved
certification mark. Engine oils
meeting the requirements for the
vehicle should have the dexos
™
1
approved certification mark. This
certification mark indicates that the
oil has been approved to the dexos1
specification.
Notice:
Failure to use the
recommended engine oil or
equivalent can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity grade oils such as
SAE 10W-30, 10W-40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below
−
29°C
(
−
20°F), an SAE 0W-30 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See
“
Specification
”
earlier in this section for more
information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
