5.2.2 Heavy Duty Diesel Engines
E1 = Obsolete
E2 = Standard
E3 = Heavy conditions (Euro 1 -- Euro 2 engines)
E4 = Heavy conditions
(Euro 1 -- Euro 2 -- Euro 3 engines)
E5 = High performance in heavy conditions
(Euro 1 -- Euro 2 -- Euro 3 engines)
5.3 Lubrication System
Use oil that displays the American Petroleum Institute
(API) service
doughnut symbol for diesel engines on the
container. Oils that identify this information meet U.S.
and international performance requirements set by the
engine manufacturers and lubricant industry including
the Society of Automotive Engineers (SAE).
See
Figure 5-1.
D
The top half of the doughnut identifies the oil
performance service level or the SAE viscosity
category. Use only the recommended API category C
for diesel-fueled engines.
D
The center of the doughnut identifies the SAE
recommended grade of oil.
D
The bottom half of the doughnut identifies the SAE
energy conservation category and may result in
overall fuel savings.
Note: Using unsuitable oil or neglecting an oil change
may result in engine damage that is not covered
by the engine warranty.
Note: DO NOT mix different oil brands. Incompatibility
could
cause a breakdown of lubricating
ingredients and reduce engine protection.

5.3.2 Oil Check
Check the oil level before starting and after every
8--15 hours of usage. Use only an approved engine
diesel oil available at your authorized Kohler distributor/
dealer.
To avoid engine damage, it is important to follow these
instructions:
D
Check engine is horizontal and level.
D
Check the oil level before each startup.
D
Check the oil level daily after the warm (not too hot to
touch) engine is in the stopped position.
D
Check that oil level does not show a reading below
the ADD mark on oil dipstick or just below reservoir
FILL mark. See Figure 5-4.
