Oil specifications

Use WSS-M2C153–F motor oil
CERTIFIED FOR GASOLINE
ENGINES by the American
Petroleum Institute.
Engine oils with an SAE 5W-30
viscosity and displaying the
American Petroleum Institute
certification mark are preferred for
your vehicle. They provide the best
engine performance, fuel economy
and engine protection for all
climates down to –25°C (-15°F).
Do not use:
• "non-detergent" oils
• oils labeled API SA, SB, SC, SD,
SE, SF or SG
• additional engine oil additives,
oil treatments or engine
treatments
Additional engine oil additives, oil
treatments, or engine treatments
are never needed and could, under
certain conditions, lead to engine
damage which is not covered by
your Ford warranty.
Synthetic engine oils which are
CERTIFIED and of the preferred
viscosity may be used in your
engine. The engine oil and oil filter
must still be changed according to
the "Service Guide."
