10-10 Vehicle Care
Use of oils that do not meet the
dexos specification, however, may
result in reduced performance under
certain circumstances.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not
use other viscosity 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 should 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, be sure to always
select an oil that meets the
required specification, dexos .
See Specification for more
information.
