ENGINE LUBRICATING OIL
DESCRIPTION
Use a heavy duty engine oil with an API classification of SJ,
SL, or SM. Change the engine oil and filter after an initial 50
hours of break-in operation. Then follow the oil change
'
interval as specified in the MAINTENANCE SCHEDULE
in this manual.
An oil viscosity of SAE-15W-40 is recommended for this
engine
in all conditions, and all seasons.
Westerbeke Corporation does not approve or disapprove
the use of synthetic oils. If synthetic oils are used, engine
break-in must be performed using conventional oil. Oil
change intervals must be
as
listed in the MAINTENANCE
SCHEDULE section of ibis manual and not be extended if
synthetic oils are used. '
NOTE: The information above supersedes all previous
statements regarding synthetic oil.
CHANGING THE ENGINE OIL
The engine oil should be warm. Remove the oil drain hose
from its attachment bracket and lower it into a container and
allow the oil to drain, or attach a pump to the end of the drain
hose and pump the old oil out. Make sure the oil drain hose
is properly secured in its holder after all of the old Qil has

WARNING:
Used engine oil contains harmful
contaminants. Avoid prolonged skin contact. Clean skin
and nails thllroughly using soap and water. Launder or
discard clothing or rags containing used oil. Discard
used oil properly.
Always observe the old oil as it is removed. A yellow/gray
emulsion indicates the presence of water in the oil. Although
this condition is rare, it does require prompt attention to
prevent serious damage. Call a competent mechanic if water
is present in the oil. Water present in the oil can be the result
of a fault in the exhaust system attached to the engine and/or
a siphoning through the water cooling circuit into the
.
exhaust, filling it up into the engine.

THE OIL FILTER
When removing the used oil filter, you may find it helpful to
ipunch a hole in the upper and lower portion of the old filter
to drain the oil into a container before removing it. This helps
to lessen spillage.
An
automotive filter wrench
~hould
be
helpful in removing the old oil filter. Place some paper towels
and a plastic bag around the filter when unscrewing it to catch
any oil that's in the filter. Inspect the old oil filter as it is
removed to make sure that the rubber sealing gasket comes
. off with the old oil filter. If this rubber sealing gasket remains
sealed against the oil filter adapter, gently remove it. When
installing the new oil filter element, wipe the filter gasket's
sealing surface on the oil filter adapter
free
of oil and apply a
thin
coat of clean engine oil to the rubber sealing gasket on
the oil filter. Screw the filter onto the threaded oil filter stub,
and tighten the filter firmly by hand.
NOTE: Use genuine WESTERBEKE oil filters. Genericfilters
are not recommended. '
REFILLING THE OIL SUMP
Add fresh oil through the valve cover. After refilling the oil,
run the engine for a few moments while checking the engine's
oil pressure. Make sure there is no leakage around the new
oil filter or from the oil drain system.
OVER-FILLING
CAUTION:
The oil sump on this generator's engine can
unintentionally be over-filled!
After shutdown, the oil in the engines internal passages can
linger and take a number of hours to drain back into the oil
sump. Allow at least a few hours for the oil to settle back into
the sump before checking the dipstick.
An
overnight period
will provide an even more accurate dipstick reading.
(Re-starting the engine is not a problem as the engine's
internal passages are well lubricated).
Over-filling the engine's sump will result in erratic operation,
and/or a smokey white oil laden exhaust, hard starting and
possible no start.
