(2) Oil Viscosity
Engine oil viscosity largely affect engine startability, performance, oil
consumption, speed of wearing and occurrence of seizure, etc. Using
lubricants whose viscosity selected 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; 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.
