Fuel, Engine Oil And Engine Coolant - Westerbeke 3.5KW SBCG-60Hz Operator's Manual

FUEL, ENGINE OIL AND ENGINE COOLANT
GASOLINE
Use only unleaded gasoline with an octane rating of 89 or
higher. Higher octane is recommended. The use of lower
octane gasoline will adversly affect engine performance.
Ethanol blends must not exceed E-lO.
When fueling, follow U.S. Coats Guard Regulations. Close all
hatches and companionways to prevent fumes from entering
the vessel. Ventilate properly after fueling and before starting
the generator or main engines.
Use only clean fresh 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. This filter rating must be 10 microns or
smaller.
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
50 hours of break-in operation. Thenfolrow the oil change
interval as specified in the MAINTENANCE SCHEDULE
section of this manual and not be extended if synthetic oils
are used.
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 use, engine break-in
must be performed using conventional oil. Oil change
intervals must be as listed in the MAINTENANCE
SCHEDULE section of this manual and not be extended if
synthetic oils are used.
NOTE:
The infonnation above supersedes all previous
statements regarding synthetic oil.
OVER-FILLING
CAUTION: The oil sump on this generator's engine can
unintentionally be over-filled!
After shutdown, the oil in the engines internal pasages can
linger and take a number of hours to drain back into the
sump. Allow at least a few hours for the oil to settle back
into the sump before checking the 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,
andlor a smokey oil laden exhaust, hard starting and possible
no start.
ENGINE COOLANT
Engine coolant a 50/50 mixture of antifreeze and distilled
water. This coolant allows the engine to run at its proper
temperature by transferring heat from the engine to the
coolant. It also lubricates and protects the cooling system
from rust and corrosion. A 50/50 mixture of antifreeze and
distilled water will protect the engine to _34°P (1.12°C).
PURCHASING ANTIFREEZE
Rather than preparing the mixture, WESTERBEKE
recommends buying the premixed antifreeze so that when
adding coolant, the mixture will always be correct.
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.
NOTE:
This coolant recovery tank, with its short length of
hose, is best located at or above the cooling systems
pressurelfill cap.
