3.3 Lubrication System
3.3.1
Oil Specifications
Use oil that meets the American Petroleum Institute
(API) classification of SC, SD, SE, SF, SG, or SH. 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
given operating temperature ranges.
Do not mix different oil brands. Incompatibility could
cause a breakdown of lubricating ingredients and
reduce engine protection.

* Using multigrade oil causes greater oil consumption.

Oil Check
Check the oil level in the crankcase daily or before each
start-up to ensure that the level is in the safe range. 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

Note: Do not operate the set if the oil level is below the
Add mark on the dipstick or above the Full mark
on the dipstick.
3.3.3
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.
3.3.4
Oil 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 Figure 3-3 for oil capacity.
