Engine lubrication for severe service operation

The following severe service operating conditions require unique engine
maintenance procedures:
• towing a trailer over 1 600 km (1 000 miles)
• sustained, high speed driving at Gross Vehicle Weight Rating

(maximum loaded weight for vehicle operation during hot
weather-above 32°C [90°F]).

• frequent or extended idling (over 10 minutes per hour of normal

driving).

• operating in severe dust conditions.
• frequent, short trips of 16 km (10 miles) or less during freezing

weather

If you are operating your vehicle under any of these conditions, observe
the following service procedures:
• Change engine oil and filter every 5 000 km (3 000 miles).
• Use Motorcraft oil or an equivalent oil conforming to Ford

Specification ESR-M2C171–C or API categories CG-4/SH. Do not use
oils labeled with only one of the following category designations, SG,
SH, CE, CF-4 or CG-4, as they could cause engine damage.

For more information refer the Severe Duty Maintenance Schedule in
the “Service Guide”.

REPLACING THE AIR FILTER ELEMENT

When replacing the air filter element, use the Motorcraft air filter
element listed. Refer to Lubricant and Maintenance Materials
Specifications
in this supplement.

Failure to use the correct air filter element may result in severe
engine damage.

1. Remove air filter element from the housing, taking care to prevent dirt
from falling into the engine air intake.

2. Clean the air filter housing and cover to ensure good sealing.

3. Install a new air filter element. Be careful not to crimp the filter edges
between the air filter housing and cover. This could cause damage to the
air filter element and possible severe damage to the engine.
