A
CAUTION:
Only
use
unleaded
fuel
with
an
octane
rating
of
89
or
higher.
Leaded
fuel
will
cause
serious
harm
to
your
engine
and
violate
your
warranty.
Care
Of
The
Fuel
Supply
Use
only
clean
fuel!
The clearance of the components in
your
fuel
injection pump
is
very critical; invisible dirt
particles which might pass through
the
filter
can
damage
these
finely
finished
parts.
It
is
important
to
buy clean
fuel,
and
keep
it clean. The
best
fuel
can
be
rendered
unsatisfactory
by
careless handling or improper storage
facilities.
To
assure that
the
fuel
going into the
tank
for
your
engine's daily
use
is
clean
and
pure,
the following practice
is
advisable:
Purchase a well-known brand of
fuel.
Install and regularly service a
good,
Coast Guard approved
metal
bowl type filter/water separator between
the
fuel
tank
and
the
engine.
ENGINE
OIL
Use a
heavy
duty engine
oil
with
an
API classification
of
SJ.
Change the engine oil
and
filter after
an
initial 50 hours
of
break-in operation,
and
every
100
hours
of operation
thereafter.
An oil viscosity of SAE
15W-40
is
recommended
for
this
engine
in
all conditions.
A
CAUTION:
Do
not
allow
two
Dr
more
brands
of
engine
oil
to
mix.
Each
brand
contains
its
own
additives;
additives
of
different
brands
could
react
in
the
mixture
to
produce
properties
harmful
to
your
engine.
ENGINE
COOLANT
WESTERBEKE recommends a mixture of
50%
antifreeze
and
50%
distilled
water.
Distilled water
is
free
from
the
chemicals
that
can corrode internal engine surfaces.
The
antifreeze performs double
duty.
It
allows
the
engine
to
run
at proper temperatures
by
transferring heat
away
from
the engine
to
the
coolant. It also lubricates
and
protects
the
cooling circuit from rust and corrosion. Use a
good
quality
antifreeze
that
contains supplemental cooling additives
(SeAs')
that
keep the antifreeze chemically balanced, crucial
to
long
term
protection.
The water
and
antifreeze should be premixed before being
poured
into
the
cooling circuit.
NOTE:
Use
the
new environmentally-friendly,
long
lasting,
antifreeze that is now available.
A proper 50/50 mixture
as
recommended
will
protect
the
engine coolant
to
temperatures of -4()0F.

COOLANT
RECOVERY
TANK
A coolant recovery tank kit
is
supplied
with
each
generator.
The
purpose of
this
recovery tank
is
to
allow
for
engine
coolant expansion and contraction
during
engine operation.
Some loss of coolant
may
occur
as
a result of evaporation
and the effects of exhaust manifold
working
temperature.
