LUBRICATION
Present day high speed driving, fast acceleration and closely fitted precision ma-
chined 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
lubrication 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.

Disconnect elbow and inject 1 ounce oil
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 71/
2
quarts for six cylinder and 9 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, therefore,
not unusual to add oil between change periods. Its rate of usage is governed by the indi-
vidual 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 sat-
isfactory 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 speedometer
indicates that the oil change period is near at hand, it is more economical to have the oil
changed at that time.
WHEN TOCHANGEENGINEOIL
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 andpan.
Caution: The use of flushing oil or compounds is not recommended. However,intheevent
they are used, it will be necessary to remove the oil reservoir and thoroughly clean it out
before installing the new oil.
THEPROPERENGINEOILTOUSE
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.

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 Ameri-
can 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 satisfactory
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 per-
mit 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.
