DO NOT use The following engine
oils.
API : CG-4, CH-4
ACEA : E-1, E-2, B grade
JASO : DH-2, DL-1
Reason
• API CG-4, CH-4
In case CG-4, CH-4 is to be used for
YANMAR YM diesel engine series,
there is a possibility that excessive
wears occur on the valve train system
due to the content of oil.
• ACEA E-1,E-2, B
These fuels are developed for the dif-
ferent type of diesel engines.
• JASO DH-2, DL-1
These fuels are developed for the dif-
ferent type of diesel engines.
(2) Selection of Oil for Marine Gear
• API Classification ........... CD or better
• SAE viscosity ................... #20 or #30
(3) Selection of Oil for Sail Drive Unit
• API service grade ....................GL4.5
• SAE Viscosity ............... 90 or 80W90
or QuickSilver® High Performance
Gear Lube
QuickSilver® is a registered trade-

(4) Handling the Lubricating Oil
1. When handling and storing lubricating
oil, be careful not to allow dust and wa-
ter to enter the lubricating oil. Clean
around the filler port before refilling.
2. Do not mix lubricating oils of different
types or brands. Mixing may cause the
chemical characteristics of the lubri-
cating oil to change and lubricating
performance to drop, reducing the en-
gine's life. Before supplying lubricating
oil to the engine and marine gear for
the first time, extract any lubricating oil
remaining in the tank. Use new lubri-
cating oil.
3. Lubricating oil supplied to the engine
will undergo natural degradation with
time even when the engine is not
used. Lubricating oil should be re-
placed at the specified intervals, re-
gardless of whether the engine is
being used or not.
If you operate your equipment at tem-
peratures below the limits shown, con-
sult your dealer for special lubricants
and starting aids.
Contact with engine oil may result in
the roughened skin. Care should be
taken so as not to contact with engine
oil wearing protective gloves and cloth-
ing.
When handling the engine oil, make
sure to use the protective gloves at any
time.
If contact, wash with soap and water
thoroughly.
