Engine Oil Service Limits for Emergency Use

In case of the engine with long waiting time for operation like emergency use engine, if the fuel level of the fuel
tank (fuel day tank) becomes higher and higher than the position of the fuel injection pump, the leak quantity per
time increases so that the possibility of dilution increases.
In accordance with the maximum head drop between the fuel level of the fuel tank (fuel day tank) between the
position of the fuel injection pump, with or without the water heater, the usage period of the engine varies, in
addition, the change interval of the engine oil must be changed accordingly.
With water heater
*Maximum head
drop (m) From 1.0 to 2.0
Use limit 1 years
* : The maximum head drop means a vertical distance from the center of the fuel injection pump drive shaft to
the fuel level of the fuel tank (fuel day tank) when fuel is filled up to the upper limit.
