Oil Specifications

Use oil that displays the American Petroleum Institute
(API) Starburst certification mark for gasoline engines
on the container. Using unsuitable oil or neglecting an
oil change may result in engine damage that is not
covered by the engine warranty. Figure 3-1 shows the
recommended Society of Automotive Engineers (SAE)
viscosity designation for a given operating temperature.
Ambient Temperature
--18_C (0_F) or above
Below --18_C (0_F)

Do not mix different oil brands. Incompatibility could
cause a breakdown of lubricating ingredients and
reduce engine protection.
3.4.2

Oil Check

Check the oil level in the crankcase every 24 hours of
operation or before each startup. Do not check the oil
level while operating the unit. Stop the generator set
and keep the generator set level to get an accurate
reading. To check the oil level, remove the dipstick and
wipe the end clean, reinsert and remove. Maintain the
oil level between the Full and Add marks on the dipstick,
as shown in Figure 3-2. See Section 1, Service Views
for the dipstick location.
Note: Do not operate the set if the oil level is below the
Add mark or above the Full mark on the dipstick.

Oil Additions

Adding some oil between oil changes is normal. The
amount varies with generator set usage. Open the oil fill
cap and pour in a small amount of oil using a funnel or
other suitable pouring device. See Section 1, Service
Views, for the oil check and oil fill locations.
3.4.5

Oil and Filter Change

Change the oil according to the service schedule or
before generator set storage. Change the oil more
frequently if the generator set operates under dirty,
dusty conditions. Change the oil while the engine is still
warm. See Section 1, Service Views, for oil fill, oil check,
and oil filter locations.
Oil Change Procedure
Whenever possible, drain the oil while it is still warm.
1. Drain the oil.
a. Place the generator set master switch in the
OFF position.
b. Disconnect the power to the battery charger, if
equipped.
c. Disconnect the generator set engine starting
battery, negative (--) lead first.
d. Remove the housing side panel.
e. Place an oil collection container below the oil
drain and remove the oil drain plug.
f. Open the oil drain valve on the engine.
