What Kind of Engine Oil to Use
(2.0L Engine)
Look for two things:
. Viscosity Grade
SAE 5W-30 is best 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 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.
. Specification
The vehicle's engine requires a
special oil meeting the dexos™
specification.
Notice: Use only dexos™
approved engine oil or equivalent
of the appropriate viscosity
grade. Failure to use the
recommended oil or equivalent
can result in engine damage not
covered by the vehicle warranty.
The vehicle's engine was filled at
the factory with a Mobil 1
®
engine oil
that met the requirements of the
dexos™ specification. It is
recommended to use Mobil 1
