OPERATION
FreshLubeâ„¢
is an oil injection system which
automatically regulates the correct
64:l
fuel/oil
mixture required to protect and lubricate the
engine. The oil pump is a variable displacement
pump, gear driven by the crankshaft and con-
trolled by engine load and RPM to automatically
inject the correct amount of oil with gasoline to
achieve a constant
64:l
ratio.
A
sensor, located
in the oil reservoir, will stop the engine when the
oil level falls below
the
recommended level in
the reservoir.
