Proper lubrication is the life of every piece of mechanism. This is particularly true of the motor car. Correct lubrication spells the difference between long life or rapid and premature wear.
For this reason, a definite plan and schedule for application is necessary in order to provide the various bearing surfaces with the right amount of the correct lubricant at the proper intervals.
It is a well-known fact that one type of lubricant will not suffice for all applications. The degree of load carried and operating conditions make necessary the use of different types of lubricants.
In order to familiarize Hudson mechanics on the proper lubrications of the engine, chassis and body; lubricating charts indicating points to be lubricated, type of lubricant to be used and the frequency of application are shown in this Manual.
NOTE: Quality lubricants are used in the course of assembling every new car. These need not be changed until the recommended mieage period shown in the Lubricating Schedule.
Pressure lubrication to all engine bearings is maintained by a rotor type oil pump mounted on the right side of crankcase and driven by a worm gear on the camshaft. Oil is drawn by the suction side of the pump through a pipe connecting with a floating screen fixed in the pan.
The oil pump parts consist of an inner and outer rotor, a shaft and the body and cover. No adjustment of the pump is required. Oil pressure is regulated by a built-in, nonadjustable release valve and spring. These are accessible for inspection or cleaning through a plug opening at the left rear side of engine.
When the engine is started, the release valve has moved to a position that closes the oil passageway to the oil filter passageway and permits full pump flow direct through the main oil gallery, extending the full length of the crankcase. This oil gallery is intersected by drilled leads to all main and camshaft bearings and the valve tappets.
Through the drilled crankshaft, oil pressure from the main bearings is distributed to each connecting rod bearing. An angular hole drilled through the large end of each connecting rod and upper half of bearing shell deposits a uniform spray of oil on all cylinder walls.
Fitted in the front end of main oil gallery is an oil trough that conducts a small stream of oil to the timing chain and sprockets.
The oil measuring gauge seats on a tube pressed in the crankcase at the left rear side. A pressure type oil signal switch mounted above the oil pump and connected with the main oil gallery operates the dash oil signal light which shows red when the oil pressure drops below approximately 13 pounds.
Select oils from the well-known brands 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 assurance of receiving high-grade lubricants.
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 selected 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.

ENGINE OIL LEVEL - The level should be checked each time you purchase gasoline. The oil level gauge is located on the left side of the engine.
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 near the full mark. (Top line on the "Oil Level Range." Figure 3 [at right].
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 (oil pan). Oil is added through the oil filler opening by removing the filler cap.

WHEN TO CHANGE ENGINE OIL
The oil which is placed in the engine at the factory should be drained and replaced after 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.
NOTE: Darkening or discoloration of oil does not always mean that it is unsatisfactory. But evidence of dilution or dirt is good indication that the oil should be changed and the filter cartridge should be replaced.
CAUTION: The use of flushing oils or compounds is not recommended. However, in the event they are used, the oil reservoir should be thoroughly drained before installing new oil.
ENGINE OIL CAPACITIES - The total engine oil capacity is 5-½ quarts. When the oil is drained in the conventional manner, the refilling quantity is 5 quarts.
Approximately two quarts of oil are required to bring the level from the "Low" to "Full" mark.
BREAK-IN OIL - Should the use of so called "break-in" oils or special compounds for breaking in new engines be decided upon, make sure the supplier quarantees that they contain no harmful ingredients.

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.
