2003 FORD F750 oil viscosity

Engine oil and filter recommendations—7.3L Power Stroke engine
To help achieve proper engine performance and durability, it is important
that you:
•Use only engine lubricating oils and oil filters of the proper quality.
•Change the engine oil and filterno laterthan the recommended
service interval. Refer to the general maintenance information section
for the appropriate intervals for changing the engine oil and filter.
•Change your engine oil and filter more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or short driving distances.
Diesel engines require specially formulated oil to resist contamination.
Proper quality oils also provide maximum efficiency of the crankcase
ventilation system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–C or API Service
categories CH-4, CH-4/SJ or CH-4/SL. If CH-4 oil is not available, CG-4 is
acceptable.
Diesel engine oils with improved fuel economy properties (energy
conserving) are currently available. If you use an energy conserving oil,
be sure it meets Ford specification WSS-M2C171–C or API service
category designation CH-4/SL and is of the proper viscosity grade for the
temperature range in which you expect to operate your vehicle. Some
energy conserving oils do not meet the requirements necessary for your
diesel engine.

Using the chart, determine which SAE viscosity grade best suits the
temperature range in which you expect to operate your vehicle. The use
of the correct oil viscosity grade for diesel engines is important for
satisfactory engine operation.
A symbol has been developed by the American Petroleum Institute (API)
to help you select the proper engine oil. The symbol will be included on
the oil container you purchase.
The top section of the symbol shows
the API service category
designation. This should be
CH-4/SL.
The center section of the API
symbol shows the SAE viscosity
grade.
The lower section of the API symbol will stateenergy conservingif the
engine oil has been proven to have fuel savings capabilities.
Use a Ford engine oil filter, part number FL-1995 or equivalent. This
filter protects your engine by filtering harmful, abrasive or sludge
particles.
