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.

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.
