FUEL, ENGINE OIL AND ENGINE COOLANT
FUEL
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 an engine oil regular or synthetic with an API classifica-
tion of CF and/or CG-4. An oil viscosity rating of 15W-40 is
recommended for all operating conditions. Change the
engine lube oil and filter after the initial 50 hours of break-in
operation and every 100 hours or less of operations there
after.
A
CAUTION:
Do not allow two or 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
(SCAs') 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 -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
coolant expansion and contraction during engine operation,
without the loss of coolant and without introducing air into
the cooling system.
