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” earlier
in this section for more information.
