Isuzu 3LD2 - Engine Oil Selection and Viscosity

2. LUBRICANT
The quality of engine oil may largely affect engine performance,
startability and engine life.
Use of unsuitable engine oil will result in piston ring, piston 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.
(I) Engine Oil Selection
API, CC or CD grade
(2) Oil Viscosity
Engine oil viscosity largely affect engine startability, performance,
oil consumption, speed of wearing and occurence of seizure, etc.
Using lubricants whose viscosity selected according to the
atmospheric temperature is important.
NOTICE: I) Using a mixture of different brand or quality oils will
adversely affect the original oil quality; therefore, never
mix up different brand or different type 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.
