5. ENGINE OIL LEVEL
MAINTENANCE
Check the oil level daily with the engine
stopped. If the engine has just been stopped
and is warm, wait at least 10 minutes to allow
the oil to drain back to the oil pan before
checking. Wipe the dipstick clean then check
oil level. The level should always be within the
safe range on the dipstick (Fig. 8). Add the
proper grade of oil to maintain the correct level
on the dipstick. All diesel engines are
designed to consume some oil, so a periodic
addition of oil is normal.
WARNING
Touching a hot engine can cause serious
burns.
CAUTION
Do not overfill. Oil may be blown out through
the crankcase breather if the crankcase is
overfilled.
CAUTION
Clean end of tube before removing the dipstick
to prevent oil contamination.

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. 9).

6. ENGINE OIL AND FILTER CHANGE
MAINTENANCE
Both the engine oil and filter should be
changed according to the following maximum
interval (based on an oil analysis program).
Short Haul: 15,000 miles (24,000km) or once
a year, whichever comes first.
Long Haul: 30,000 miles (48,000km) or once
a year, whichever comes first.
Oil analysis program may be used to determine
whether this interval should be shorter, but
should not be used to lengthen the interval.
Short haul: 6,000 miles (10,000km) to 60,000
miles (100,000 km) annual.
Long haul: over 60,000 miles (100,000 km)
annual.
However, changes that are more frequent may
be required when the engine is subject to high
