An oil that displays this symbol conforms
to current engine, emission system and
fuel economy performance standards of

We recommend Motorcraft® motor oil for
your vehicle. If Motorcraft® oil is not
available, use motor oils of the
recommended viscosity grade that meet
API SN PLUS requirements and display the
API Certification Mark for gasoline engines.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that your
vehicle warranty does not cover.
