3.6.1 Oil Change
The engine oil change interval varies for different
engines, applications, and oil type. Identify the following
for your application and then refer to the Engine
Operation and Maintenance Manual for oil change
intervals and oil specifications.
D Engine model. See the engine nameplate or the
generator set specification sheet to identify the
engine.
D Engine oil type (category 1, 2, 3). See the engine
Operation Manual for definitions.
D Generator set engine type (fuel-optimized or
emission-optimized). Generator set models with a -F
in the model designation are fuel-optimized.
D Generator set application (standby, p rime, or
continuous).
Note: Change both the oil filters and centrifugal oil filter
(if applicable) during the oil change.

Figure 3-5 Automatic Oil Replenishment System
The oil replenishment system typically works with an oil
reservoir to maintain a constant oil level in the engine
crankcase. As the oil level in the crankcase drops, the
valve inside the oil level regulator opens to supply fresh
oil from the oil reservoir.
Note: The pressure-equalizing vent line between the oil
regulator and the engine prevents positive or
negative crankcase pressure.
Adjusting the oil level regulator position
The oil level regulator can be adjusted by changing the
positioning of the regulator on the mounting bracket.
Use the following procedure:
Note: If the oil level regulator runs continuously, lower
the oil level regulator position approximately
10 mm (3/8 in.) on the bracket to prevent the
excess use of oil.
1. Start the engine and allow the oil level to stabilize.
2. Check the oil level on the dipstick. If the oil level is
low, adjust the regulator higher on the bracket to
allow more oil into the crankcase. If the oil level is
above the full line on the regulator, drain the excess
oil out of the crankcase and move the regulator
down on the bracket.
3. Repeat until desired running oil level is achieved.
