4. Protecting yourself from engine
heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required. The distance from ADD to
OPERATING RANGE on the dipstick represents 1.9L (2 quarts). Do not
overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.
Engine oil specifications
To help achieve proper engine performance and durability, it is important
that only engine lubricating oils of the proper quality are used in your
Diesel engine and that the engine oil is changedno laterthan the
recommended interval. Diesel engines require specially formulated oil to
resist contamination. Proper quality oils also provide maximum efficiency
of the crankcase ventilating 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, CH-4/SL or DHD-1. If CH-4 oil is not available,
CG-4 is acceptable.
Engine oils with improved fuel economy properties (energy conserving)
are currently available. If you use an energy conserving oil, be sure it
meets the recommended Ford Specification,APIservice categories and
SAE viscosity grades listed in the Lubricant and Maintenance Materials
Specifications chart. Some energy conserving oilsdo notmeet the
requirements necessary for your Diesel engine.
