Lubrication
Engine
Use High-Grade Oil—Medium Heavy Body (S. A. E. 30)
Select an oil for winter driving that
will flow at the lowest temperature
encountered. Consult your dealer if
you are in doubt as to what oil to use.
When the ignition switch is turned
"on" the red jewel to the left of the
center of the instrument board should
flash red. If it does not, the bulb is
either burned out, the circuit to the oil
relief valve broken or the oil relief
plunger sticking.
As soon as the engine is running,
the light should go out. A flash of the
red jewel while the engine is running
above idling speed indicates interrup-
tion of the oil supply. The engine
should be stopped immediately and
the lubrication system inspected.
The amount of oil in the reservoir is shown on the gauge on the instrument
panel marked "Gas or Oil" when the ignition electrolock is turned "on" (turn
to left to read gauges without starting engine) and the button under the
instrument panel below the ignition lock is pressed up.
A bayonet gauge is also provided at the oil filler on left side of the engine.
See illustration.
The Hudson Duoflo oiling system provides not only purification from
dilution but also double screening and cooling of the oil. The oil is therefore
maintained in good condition for a longer time than in other lubricating
systems. Oil should he added as necessary to maintain the quantity in the
reservoir. The reservoir should be drained and refilled with eight (8) quarts of
oil every 1000 miles.
It is, however, recommended to drain the initial supply of oil after the first
500 miles of driving. To drain the reservoir remove the plug from the rear of
the oil reservoir. Be sure the drain plug is tightened securely when replaced.
