FUEL, ENGINE OIL AND ENGINE COOLANT
GASOUNE
A
Only use unleaded gasoline with an
. . CAUTION:
Oetane rating of#89 or higher. A
.lower Octane rating may result in a power loss.
Leaded fuels will harm your CO system and engine
. and will void unit warranty.
Care
Of The Fuel Supply
Usc only clean, well filtered gasoline. The passages in the
carburetors and the clearances in the fuel injection equipment
are very critical for proper fuel flow. Small contaminants not
captured in the primary filter/water seperator can clog these
passages and affect these clearances,
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 usc 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,
SL or SM. Change the engine oil and filter after an initial
SO hours of engine break-n operation. Then follow the oil and
filter
change intervals as specified in the MAINTENANCE
SCHEDULE in this manual.
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 in this manual and not to be extended if
synthetic oils are used.
NOTE: The information above supersedes all previous
statements regarding synthetic oil useage.
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 engme 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 (SCAs')
that keep the antifreeze chemically balanced, crucial to long
tenn protection.
The water and antifreeze should be premixed before being
poured IOta the cooling circuit.
NOTE:
Use the new environmentally{riendly, long lasting,
antifreeze that is now available.
A proper SO/50 mixture as recommended will protect the
engine coolant to temperatures of
-40°F.

COOLANT RECOVERY TANK
A coolant recovery tank kit is supplied with each generator.
The purpose of this recovery tank is to allow for engine
c~olant
expansion and contraction during engine operation,
WIthout the loss of coolant and without introducing air into
the cooling system.
