In order to properly protect your engine, you should use motor oils marked on the container as meeting S.A.E.
Classifications SE, SD or Ford Specification ESE-M2C101-C. Oils meeting these specifications have been formulated to
keep the engine operating at peak efficiency and inhibit the formation of corrosive acids.
When you change or add oil, you should select oil with the proper specifications and with the viscosity, selected
from the following table, which most closely matches temperature range you expect to encounter for the next 100 hours of
SINGLE VISCOSITY OILS
-100F to +320F
+10OF. to +60°F
+32OF to +90°F
-100F. to +900F. (or above) 10W-40
Above +1 0°F
Where sustained high RPM operation is anticipated, use 20W20.
Your engine is equipped with a Motorcraft oil
filter. A filter of this quality should be used throughout the
life of the engine. It is designed to protect your engine by
filtering harmful abrasive and sludgy particles without
clogging up or blocking the flow of oil to vital engine
parts. This filter is especially designed for use in engines
built by Ford to give successful operation with the
recommended oil and filter change intervals.
