216 Service and maintenance
If you are unsure whether your oil is
approved to the dexos™
specification, ask your service
provider.
Use of substitute engine oils if dexos
is unavailable: In the event that dexos
approved engine oil is not available at
an oil change or for maintaining
proper oil level, you may use
substitute engine oil of the qualities
mentioned below. Use of oils that do
not meet the dexos specification,
however, may result in reduced
performance and engine damage
under certain circumstances.
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use.
Selecting the right engine oil
Selecting the right engine oil depends
on both the proper oil specification
and viscosity grade.
Engine oil specification
■ dexos1, dexos2
■ API SM, ACEA-A3/B3: Optional for
Gen1 engine (not used for Gen2
engine)
Specification
Use and ask for licensed engine oils
with the dexos™ approved
certification mark. Engine oils
meeting the requirements for the
vehicle should have the dexos™
approved certification mark. This
certification mark indicates that the oil
has been approved to the dexos™
specification.
Your vehicle’s engine was filled at the
factory with dexos™ approved engine
oil.
Use only engine oil that is approved
to the dexos™ specification or an
equivalent engine oil of the
appropriate viscosity grade. Use of
oils that do not meet the dexos
specification, however, may result in
reduced performance and engine
damage under certain
circumstances.
If you are unsure whether your oil is
approved to the dexos™
specification, ask your service
provider.
If you don’t know vehicle engine type,
ask your authorised repairer.
Engine oil viscosity
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures:
The first figure, followed by a W,
indicates low temperature viscosity
and the second figure the high
temperature viscosity.
The SAE viscosity rating defines the
ability of an oil to flow. When cold, oil
is more viscous than when hot.
Engine oil viscosity grade for 1.0D,
1.2D Gen1
SAE 5W-30 is the best viscosity
grade for your vehicle. Do not use
other viscosity grade oils such as
SAE 20W-50.
