2021 LINCOLN AVIATOR Owners Manual

Engine Oil An oil that displays this symbol conforms to
current engine, emission system and fuel
economy performance standards of ILSAC.
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 SP 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.
