CARE
OF
THE
FUEL
SUPPLY
A
CAUTION:
Only
use
unleaded
fuel
with
an
octane
rating
of 89
or
higher.
Leaded
fuel
will
cause
serious
harm
to
your
engine
and
riolate
your
warranty.
Use
only
clean
fuel!
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 good well known brand
of
oil and try to stay with
the brand you select.
Use
"ONLY" SAE 40W oil with
an
API code
of
SJ
or
better
in
this engine. Do Not use any multi grade oils.
Change the engine's lube oil and oil filter after the initial
50
hours
of
break-in operation and then every
100
hours
of
operation there after.
A
CAUTION:
Do
not
allow
two
or
more
brands
of
engine
oil
to
mix.
Each
brand
contains
its
own
addi-
tires;
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,
when
possible. Distilled water
is
free
from
the chemicals that
can
corrode
internal
engine
surfaces.
The
antifreeze performs double
duty,
as
it
allows
the
engine
to
run
at
proper temperatures
by
transferring heat
away
from
the
engine
to
the
coolant. It also
lubriciltes
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 tenn protection.
The water
and
antifreeze should be pre-mixed before being
poured into
the
cooling circuit.
NOTE:
Use the new environmentally{riendly long lasting
antifreeze that is now available.

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,
without
the
loss of coolant
and
without introducing air into
the cooling system.
