Add enough oil to put the level somewhere in the proper
operating range. Push the dipstick all the way back in
when through.
Selecting the Right Engine Oil
Selecting the right engine oil depends on both the
proper oil specification and viscosity grade:
Specification
Use and ask for engine oils with the dexos™
certification mark. Oils meeting the requirements of the
vehicle should have the dexos certification mark on the
container. This certification mark indicates that the oil
has been approved to the dexos specification.
This vehicle was filled at the factory with
dexos‐approved engine oil.
Notice: Use only engine oil that is approved to
the dexos specification or an equivalent engine
oil of the appropriate viscosity grade. Engine oils
approved to the dexos specification will show the
dexos symbol on the container. Failure to use the
recommended engine oil or equivalent can result in
engine damage not covered by the vehicle warranty.
If you are unsure whether the 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 displaying the
API Starburst symbol and of SAE 5W-30 viscosity
grade. Use of oils that do not meet the dexos
specification, however, may result in reduced
performance under certain circumstances.
