ENGINE IDLE HOUR METER (IF EQUIPPED):
Your vehicle may be equipped with an idle meter to indicate how much time the vehicle is idling in P (Park)
or N (Neutral). The meter is incorporated with the vehicle odometer. Depressing the odometer-reset button
once will display the trip odometer (miles followed by a “T” for trip odometer). Depressing the odometer-reset
button a second time will display the idle meter (hours followed by an “H” for hours). The idle meter
only accumulates time when the vehicle is in P (Park) or N (Neutral). Displayed time is cumulative for the
vehicle.It cannot be reset to zero.
Police/Fleet vehicles often experience long periods of idling,
during which engine oil will continue to break down but mileage is not accumulated on the odometer.
To assist fleet managers in maintaining proper oil change intervals, the idle meter will help determine when
an oil change is required. For every hour that the vehicle idles, it has accumulated the equivalent of
approximately 33 miles of driving. Using the combination of the vehicle odometer and idle meter allows
the fleet manager to better determine when the oil needs to be changed
Engine idle hour meter calculation:
Idle hours x 33 = miles equivalency
Miles driven + miles equivalency = oil change interval
Example:When the odometer has accumulated 3,000 miles and the idle meter shows 61 hours, a
5,000 mile oil change interval will have been reached: 3,000 road miles + (61 idle hours x 33 miles/idle
hour) = 5,013 miles.

In addition, there are several exceptions to the Normal Schedule. They are listed below:
Normal Vehicle Axle Maintenance
❑Rear axles and power take off (PTO) units containing synthetic lubricant and light duty trucks equipped with
Ford-design axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected,
service is required or the axle assembly has been submerged in water. The axle and PTO lubricant should be
changed anytime the axle and PTO have been submerged in water. During extended trailer tow operation above 70°F
ambient and wide open throttle for extended periods above 45 mph, non-synthetic rear axle lubricants
should be replaced every 3,000 miles or 3 months, whichever occurs first. The 3,000 mile lube change interval
may be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification
WSL-M2C192-A, part number F1TZ-19580-B or equivalent. Add friction modifier C8AZ-19B546-A (EST-M2C118-A)
or equivalent for complete refill of Traction-Lok rear axles (see
Owner’s Guidefor quantity). The axle
lubricant should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery Vehicle Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles. Rear axle lubricant change may be waived if the axle was
filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B
or equivalent. Add four ounces of additive friction modifier C8AZ-19B546-A (EST-M2C118-A) or equivalent for
complete refill of Traction-Lok rear axles. The axle lubricant should be changed anytime the axle has been submerged
in water.
E–450 and F–450/550 Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles under normal driving conditions on all E–450 and
F–450/550 applications. For E–450 and F–450/550 vehicles operated at or near maximum Gross Vehicle
Weights, the rear axle lubricant should be replaced every 50,000 miles. In addition, this 50,000 mile schedule
should be observed when the vehicles are operated under the Special Operating Conditions, where noted, on
page 41.
California Fuel Filter Replacement
❑If vehicle is registered in California, the California Air Resources Board has determined that the failure to
perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion
of the vehicle’s useful life. Ford Motor Company, however, urges you to have all recommended maintenance
services performed at the specified intervals and to record all vehicle service.
Class A Motorhome
❑Every two years - Change brake fluid❑Every 60,000 miles - Change automatic transmission fluid
