Oil Filter and Bypass Oil Filter - Replace
1.
Clean around the oil filters.
2.
Prepare drip pans, and place them under oil filters
and a bypass oil filter.
3.
Using a filter wrench, remove oil filters and a by-
pass oil filter.
Note: Disconnect the removed oil filters and a bypass
oil filter, and check elements for metal particles.
If metal particles are found, contact a dealer of
Mitsubishi Heavy Industries, Ltd.
4.
Thoroughly wipe off oil on the oil filter mounting
surface of the filter bracket with a cloth.
5.
Check the new oil filters and a bypass filter for
proper seating of gasket.

Engine Oil for Mixing of Fuel and Water - Inspect
Sample 1 to 2 L [0.26 to 0.53 U.S. gal.] of engine oil, and check for abnormal odor and discoloration to determine
the mixing of fuel and water.
If fuel is mixed with the engine oil, the oil will smell like fuel.
If water is mixed with the engine oil, the oil will be milky white.
If fuel or water is detected in the engine oil, find the cause of the problem, and repair. If the problem cannot be cor-
rected easily, contact a dealer of Mitsubishi Heavy Industries, Ltd.
Do not use a filter with the dented case. Filter dam-
age or oil leakage may occur and it can cause fire
hazard.
Do not use a filter wrench to install the oil filter and
bypass oil filter.
Do not dent or scratch the oil filter surfaces.

to gasket.
If the engine continues to operate with engine oil mixed with fuel or water, the engine oil viscosity decreases and
this can cause serious accidents such as seizing of bearings.
