CAUTION
If the oil level is constantly above normal and
excess lube oil has not been added to the
crankcase, consult with an authorized Detroit
Diesel service outlet for the cause. Fuel or
coolant dilution of lube oil can result in serious
engine damage.
The vehicle may be provided with an oil reserve
tank in the engine compartment. To adjust oil
level, open the oil reserve tank drain valve and
allow oil to discharge into the engine until the
"Full" mark on the dipstick is reached then close
the valve. Check oil reserve tank level and pour
oil in the reserve tank if necessary (Fig. 13).

6. ENGINE OIL AND FILTER CHANGE
Both the oil and filter should be changed every
12,500 miles (20,000 km) or once a year,
whichever comes first. However, changes that
are more frequent may be required when the
engine is subject to high levels of contamination
and/or overheating. Change intervals may be
decreased or gradually increased with
experience on specific lubricants until the most
practical service condition has been established.
Always refer to the lubricant manufacturer's
recommendations (analysis of drained oil can be
helpful).
CAUTION
Do not use solvents to dilute the engine oil
when draining. Dilution of fresh oil can occur
which may be detrimental to the engine.
Change engine oil with the vehicle on a flat and
level surface and with the parking brake applied.
It is best to drain the oil when the engine is still
warm.
1. From under the vehicle, remove the engine
drain plug on the oil pan. Allow oil to drain
(Fig. 14).
WARNING
Hot engine oil can cause serious burns. Wear
coveralls with sleeves pulled down and gloves
to protect hands.
2. Reinstall the drain plug.
3. Remove the spin-on filter cartridge using a
½" drive socket wrench and extension.
4. Dispose of the used oil and filter in an
environmentally responsible manner in
accordance with state and/or federal (EPA)
recommendations.
