OILS AND GREASES ARE MUCH CHEAPER THAN REPAIR BILLS AND SHOULD BE APPLIED REGULARLY
IF YOU ARE TO SECURE A MAXIMUM OF USEFUL SERVICE FROM YOUR CAR. IT IS CONSEQUENTLY
IMPORTANT THAT THE PROPER GRADE OF LUBRICANT, AS NOTED IN THE FOLLOWING, BE USED.
SAE No. 20 OIL. Use when temperatures are 75° F., and above. (Summer months.)
Where S. A. E. No. 20 Oil Is Not Available, S. A. E. No. 30 May be Used.
20-W OIL. Use when temperatures range between 75° F., and freezing -32° F.
(Fall and Spring months.)
10-W OIL. Use when temperatures range between freezing — 32°F.--and
15° below zero. (Winter months.)
10-W OIL PLUS 10% KEROSENE. Use in extreme cold weather when temperatures fall
below 15° below zero for protracted periods.
It is imperative that the recommended light oils be used in the engine during
the "breaking-in" period.
Light oils assure a better "breaking-in" of the engine as they assure
ease of starting the engine; prompt flow of a sufficient quantity of oil to the
bearings; less friction between moving parts; less wear of moving parts; etc.
Carefully follow the instructions for the "breaking-in" of your engine,
shown on the windshield of all new cars.
When starting a cold engine, it will be noted that the oil gauge on the instrument
panel will register a high oil pressure. As the engine warms up, the pressure
will drop until it reaches a point where changes to higher speeds will raise
the pressure very little, if at all.
Never run your car at high speeds when the oil gauge hand, or pointer, is above
After the engine is "run-in," slightly heavier oils, as recommended
above, may be used. In those localities where S. A. E. No. 20 Oil is not available,
S. A. E. No. 30 Oil may be used, provided the manufacturer's specifications show
it to be within the lower portion of the S. A. E. No. 30 Oil viscosity range.
Obtain the assurance of the Oil Station Attendant before permitting the oil to
be put in your engine.
Oil is carried in a reservoir located at the bottom of the crankcase and is filled
through a filler tube on the left side of the engine, just back of the generator.
