Scheduled Maintenance Guide
❑
If operating conditions are normal and you drive your Ford, Lincoln or Mercury vehicle under typical, everyday conditions
and you are using an API performance category oil of SL or later (for example SM, etc.) then you can follow the
7,500 mile (12,000 km) normal service oil change intervals schedule. Vehicles operating in the Middle East, North Africa,
Sub-Saharan Africa or locations with similar climates must follow the oil change interval of 3,000 mile (5,000 km) if the
owner is using oils defined by the American Petroleum Institute (API) performance category of API SK or earlier (for ex-
ample SJ, etc.).
Engine air filter & cabin air filter replacement
❑
Engine air filter and cabin air filter life is dependent on exposure to dusty and dirty conditions. Vehicles operated in these
conditions will require frequent inspection and replacement of the engine air filter and cabin air filter.
