It is good for reasons of economy and to forestall unexpected need of service to have your car inspected once a month or at 1000 mile (1609 km.) lubrication periods. An ideal time to have many of the parts or units inspected is while the car is on the lubrication hoist in the raised position.
Lubrication Operations
Proper lubrication is good assurance that your car will continue to perform with increasing satisfaction. Only high quality lubricants should be used on your car.
Your Studebaker dealer knows every lubrication requirement for your car. Take it to him for periodic lubrication. The recommendations given in the following paragraphs are, in many ways, the most important in the entire booklet. If a lubrication service must, of necessity, be performed by a non-Studebaker serviceman, be sure he understands the requirements mentioned in this section and on the charts on pages 28, 29, and 30.
Universal Joints Lubricate with light weight chassis lubricant at 1000 mile (1609 km.) intervals. Only a low pressure (hand) gun should be used to lubricate these bearings.
Transmission Lubricant The transmission should be filled to the level of the filler plug hole with S.A.E. 90 mineral oil gear lubricant or S.A.E. 40 engine oil, both summer and winter. On cars equipped with overdrive transmission, fill slowly, using the fill hole of the main case. For transmission capacities, see table on page 53.

The Lubrication Points Established Are For Average Use and Should Be Changed to Suit Individual Operating Conditions
(Continued from page 27)
Rear Axle Lubricant Use Studebaker hypoid lubricant or any S.A.E. 90 hypoid lubricant (multi-purpose type gear lubricant) for summer and winter. Do not mix various brands of hypoid lubricants. Use light engine oil for flushing. Do not use kerosene.
Crankcase Oil Level The oil in the crankcase is checked by withdrawing the oil level gage on the left side of the engine. The oil filler pipe cap contains a filtering element to clean the air of any impurities before it enters the crankcase. This filter is easily cleaned by removing the cap and immersing it in kerosene. Allow filter cap to dry thoroughly. Then dip cap in a good grade of engine oil so that filtering element is thoroughly oil coated. Drain off excess oil and replace cap. It’s a good idea to have the oil level checked when purchasing gasoline.
Never allow oil level shown on oil level gage to fall below the ADD OIL mark. DO NOT OVERFILL.
Engine Oil Filter The Fram oil filter (on cars so equipped) assists in removing dirt and foreign matter from the oil and is provided with a replaceable filter element.
Under normal conditions the Fram Filter cartridge should be replaced after approximately every 5000 miles (8046 km.) of operation. Severe dust conditions may warrant replacing the cartridge at correspondingly lower mileages.
When it is necessary to replace the cartridge, care should be taken to see that a new cover gasket is installed and that the cover is securely tightened. The cover should also be checked occasionally to make sure that it remains tight.
Engine Oil Renewal Engine oil should be changed at least by the end of the first 1000 miles (1609 km.). After this period the oil should be changed regularly, the frequency depending on the condition of the oil as affected by operating and atmospheric conditions.
Under average driving conditions oil should be changed at 2500 to 3000 mile (4023 to 4828 km.) intervals.
Engine Oil Viscosity “Engine oil viscosity” is a term which indicates, broadly, the “body” of the oil to be used in your engine, although other scientific considerations enter into assigning viscosity numbers to oil.
Change oil filter element every 5000 miles!
Check oil level whenever you buy gasoline!
Generally speaking, you use a thin oil in winter because it flows more freely in cold temperatures than a thick oil. Since, as stated above, the oil in your car’s crankcase, if of good quality, will be useful for many hundreds of miles, it is impractical to change oil more often than necessary. Therefore, we list below the viscosities of engine oil recommended for your car at lowest prevailing temperature generally expected in your locality during the various seasons of the year.
{uncaptioned}
| LOWEST TEMPERATURE ANTICIPATED | OIL RECOMMENDATION |
| +32° F. (0° C.) | S.A.E. 30 |
| +10° F. (-12.2° C.) | S.A.E. 20 |
| -10° F. (-23.3° C.) | S.A.E. 10W[2] |
| Below -10° F. (-23.3° C.) | S.A.E. 5W[3] |
[2]Oil in cans marked 10W or S.A.E. 10-10W is satisfactory for use where S.A.E. 10W is recommended.
[3]The engine should not be operated at sustained high speeds when using S.A.E. 5W engine oil.
Most of the higher priced motor oils sold today contain chemical detergents which hold extremely small particles of carbon or other foreign matter in suspension. Many of the particles are so small that they flow through the oil filters with the oil and remain in suspension. For this reason, oil which is perfectly good for lubrication purposes may be discolored when seen on the oil level gage. With such oils the need for an oil change should be governed by the mileage the oil has been used and the dust conditions prevalent during that mileage. As long as the oil retains a “slick” quality and good body, it is generally satisfactory.
