LUBRICATION
Present day high speed driving, fast acceleration and closely fitted precision machined
parts, place engine and chassis lubrication in the category of highly specialized services.
A definite plan of application is necessary to provide the various working surfaces with
the right amount of the correct lubricant at the proper time. Contrary to general belief, one
lubricant will not suffice for all parts of the chassis. The varying load demands and operating
conditions which the various parts are subjected to, call for different types of lubricants to
minimize friction and reduce wear.
Your Authorized Hudson Dealer has been provided with the correct factory lubrica-
tion specifications for your car, as well as the definite plan of application. This is your
assurance that the lubrication requirements of your car will be met with the greatest care.
Be sure to consult him on this most important matter.
For your guidance, a copy of the Lubrication Chart is attached to the front cover of
this manual. Additional information regarding the lubrication requirements of your car are
given in the Lubrication Schedule shown below and elsewhere in this manual, under the
description of the various units.
The lubricants placed in your car at the time of assembly are of the best quality and need
not be changed until the recommended change period shown in the Lubrication Schedule
has been reached.

IMPORTANT: When checking the level of the lubricant in the rear axle and transmission,
make sure that the lubricant has stopped foaming. If the car has been run for a consider-
able length of time, it should be permitted to stand long enough to allow the oil to reach
the true level before checking.
BREAK-IN OIL
Special compounds or so-called "break-in" oils are not necessary in Hudson engines.
In the event it is decided to use them, make sure the supplier guarantees that they contain
no harmful ingredients.
ENGINE OIL CAPACITIES
The total engine oil capacity is 7-1/ 2 quarts for six cylinder and 8 quarts for eight
cylinder engines. When the oil is drained in the conventional manner, the refilling
quantity is 7 quarts for both six and eight cylinder engines.
When the oil reservoir is removed for cleaning or during service work, two quarts
should be placed in the oil reservoir tray of eight cylinder engines before the reservoir is
installed. The remaining seven quarts should then be placed in the reservoir through the
crankcase filler opening. In six cylinder engines, the entire quantity is poured through the
crankcase oil filler pipe.
CHECKING ENGINE OIL LEVEL
An engine in normal operating condition is expected to use some oil and it is, there-
fore, not unusual to add oil between change periods. Its rate of usage is governed by the
individual engine and is dependent on operating speeds, temperatures and the viscosity
and quality of the oil used.

The level should be checked each time
fuel is added. The oil level gauge is
located on the left side of the engine
and is divided at its lower end to show
the "Oil Level Range" and the "Low
Range".
For normal operation, the oil level is
satisfactory when it is within the "Oil
Level Range". For high speed operation,
the level should be maintained at the full
mark, which is the top line on the "Oil
Level Range".
To make an accurate check, it is best to
wait a minute or two after shutting off the
engine to permit the oil to drain back into the reservoir. Approximately three and
one-half quarts of oil are required to bring the level from low to full in both
six and eight cylinder engines. If the level happens to be low and the speedom-
eter indicates that the oil change period is near at hand, it is more economical to have
the oil changed at that time.
WHEN TO CHANGE ENGINE OIL
The oil which is placed in the engine at the factory is satisfactory for the first 500
miles of operation.
Thereafter, at intervals of 2,000 miles, the reservoir should be drained and
refilled with new oil of good quality. If the car is operated constantly in dusty
areas or for short distances at low speeds during cold weather, which permits
foreign matter and sludge to accumulate, it should be changed more frequently.
However, the actual change period is largely dependent on the individual driving
circumstances.
The oil is drained by removing the plug at the rear of the oil reservoir. To insure
complete draining, it is important that the operation be performed while the
engine is warm.
It is good practice to remove the oil reservoir at least twice
a
year, preferably in
the spring and fall, to permit thorough cleaning of the screens and pan.
Caution: The use of flushing oil or compounds is not recommended. However, in
the event they are used, it will be necessary to remove the oil reservoir and thoroughly
clean it out before installing the new oil.
THE PROPER ENGINE OIL TO USE
The use of high-grade engine oil of the correct type is of great importance in
obtaining maximum performance and satisfaction from your car. Select oils from
well-known and dependable brands, of which there are many on the market, and
of the proper viscosity to suit your seasonal and driving requirements.
14 HUDSON OWNER MANUAL

The oil refiners or marketers supplying oils are responsible for the quality of their
product and their reputation is the car owner's best assurance of receiving high-grade
lubricants.
TYPES OF OIL
The various types of oil marketed for engine lubrication has been defined by the
American Petroleum Institute, as follows:
REGULAR MOTOR OIL—This term is used to designate a straight mineral oil. Oils of
this type are generally suitable under moderate driving conditions.
PREMIUM MOTOR OIL—This term is used to designate an oil having proved oxida-
tion, stability and bearing corrosion preventative properties. Oils of this type are generally
suitable for use where operating conditions are such that regular oils do not give satisfac-
tory service.
HEAVY-DUTY MOTOR OIL—This term is used to designate an oil having proved
oxidation, stability, bearing corrosion preventative properties and detergent-dispersent
characteristics. Oils of this type are generally suitable for use in both high-speed diesel and
gasoline engines under heavy-duty service conditions.
It is most important that the oil should have the ability to flow at low temperatures to
permit easy starting and at the same time, afford adequate lubrication when the engine is
at normal operating temperatures. The oil se-
lected should be based on its ability to perform
these two functions at the lowest anticipated
temperatures expected before the next oil
change period. The following table will be
helpful in making this selection.

Note: Kerosene should be added only when

available in your locality, will be glad to help
you with your lubrication problems.

OPERATING CONTROLS
Arrangement and functions of the instru-
ments and controls of your new Hudson have
been planned for maximum convenience and
comfort of the driver, as well as for safety. If
you have driven Hudsons previously or are a
first time Hudson owner, you will want to
know all about the newer controls before driv-
ing your new car. We, accordingly, recom-
mend that you read the following instructions
carefully.
SEAT ADJUSTING LEVER —Raising the
lever on the left side of the front seat permits
the seat to be moved forward or backward to
the position most convenient for the driver. As
the seat moves forward, it rises, permitting
short persons to sit higher; thus making for better vision. Seat locks in position when lever
is released.
(1) DIRECTION INDICATOR LEVER—Push lever upward for right turn and downward
for left turn. Lever returns to "Off" position automatically when turn is completed.
(2) STARTER BUTTON—Pressing button in with ignition switch turned on operates the
starter. On cars equipped with Super-Matic Drive, or Drive-Master, the clutch pedal must
be pushed down before the starter will operate. Do not press button when engine is
running or car is in gear.
(3) DIRECTION INDICATOR LIGHT—Light flashes with front and rear indicator
signals.
(4) OIL PRESSURE INDICATOR — Shows red when ignition is turned on and engine
not running. Light should go out when engine is started. If it does not, shut off engine and
determine cause.
(5) FUEL GAUGE—Indicates the level of the fuel in the gasoline tank when the ignition
switch is turned on. When needle reaches "empty" mark, approximately 1-1/2 gallons of
fuel remains in reserve.
(6) TEMPERATURE GAUGE—Indicates temperature of water or anti-freeze when
ignition is turned on. When ignition is turned off, the pointer returns to the "H" position
at the right side of the dial.
