If fungus or bacteria has caused fuel system problems, you
should have your authorized dealer correct these problems.
Then, use a diesel fuel biocide to sterilize the fuel system (fol-
low the biocide manufacturer's instructions). Biocides are
available from your dealer, service stations, parts stores and
other automotive places. See your authorized dealer for
advice on using biocides in your area and for recommenda-
tions on which biocides you should use.
(6) Smoke Suppressants
Because of extensive testing of treated fuel versus
untreated fuel, the use of a smoke suppressant additive is not
recommended because of the greater possibility of stuck rings
and valve failure, resulting from excessive ash deposits.
5.2 Lubricant
The quality of engine oil may largely affect engine perfor-
mance, startability and engine life.
Use of unsuitable engine oil will result in piston ring, pis-
ton and cylinder seizure and accelerate the sliding surface
wear causing increased oil consumption, lowered output and,
finally engine failure. To avoid this, use the specified engine
oil.
(1) Engine Oil Selection
Quality better than CD grade by API classification engine
oil must be used for the Shibaura engines.
(2) Oil Viscosity
Engine oil viscosity largely affect engine startability, per-
formance, oil consumption, speed of wear and occurrence of
seizure, etc.
Using lubricants with viscosity rated according to the
atmospheric temperature is important.
CAUTION:
1. Using a mixture of different brand or quality oils
will adversely affect the original oil quality; there-
fore, never mix different brands or different types
of oils.
2. Don't use API, CA, CB grade and reconstituted
engine oil.
3. Engine damage due to improper maintenance, or
using oil of the improper quality and/or viscosity,
is not covered by the warranty.
