AFTER THE FIRST 500 MILES
For the best all-around engine performance after the first 500 miles,
SAE 20-W or SAE 20 engine oil should V>
4 during summer
weather. If your car is regularly driven a: - if the
prevailing daylight temperature averages :: ;•"., SAK 30
oil may be used.
For cold weather, oil should be selected that will permit easy
starting at the lowest temperature anticipated for the entire
period. Unless the proper oil is selected, you may have difficulty
starting your car if the temperature drops i-i:: nly. The viscosity
grades of engine oil for use in your Cadillac at the various cold
weather temperatures are given below.
If you anticipate that the minimum
atmospheric temperature will be: ^^ tirade:
Not lower than 32° F. above zero . SAE 20-W or SAE 20
Not lower than 10° F. above zero SAE 20-W
Not lower than 10° F. below zero SAE 10-W
Below 10° F. below zero SAE 5-W*
*NOTE: Improved SAE 5-W oils combine the low temperature
easy starting characteristics of 5-W with the performance characteristics
of high quality 10-W at the higher engine operating
temperatures. SAE 5-W oils are intended for use under all operating
conditions and under all atmospheric temperatures that may be
encountered when below zero temperatures may be expected. They
should be used not only at the lower temperatures, but may he
retained in the crankcase for use during the warmer days that occur
during the winter season. Look for the identification "For Service
MS" or "For Service DG" on the container.
BE SURE THAT YOU ALWAYS GET
THE PROPER, AUTHORIZED FLUID
FOR HYDRA-MATIC DRIVE
Cadillac Hydra-Matic Drive operation depends upon the use of
a fluid of very exacting specifications, compounded especially for
automatic transmissions. This fluid can be obtained from Authorized
Cadillac Dealers and reputable service stations who carry
fluid which has been qualified by General Motors Corporation for
use in Cadillac Hydra-Matic Transmissions. Approved Hydra-
Matic Fluid is identified for the protection of the car owner by the
qualification number "AQ-ATF — — —." Authorized Cadillac
Dealers will check the fluid level in your Hydra-Matic Drive
every 2,000 miles at the same time that your car is being lubricated
—and, if necessary, they will add fluid.
The Cadillac Hydra-Matic Drive should be completely drained
and fresh fluid supplied every 25,000 miles.

MAINTAIN PROPER
OIL LEVEL
ENGINE OIL
LEVEL INDICATOR
The engine crankcase oil capacity is
five quarts. Always maintain the proper
oil level. The oil indicator is marked for
a safe driving range. Whenever the
level falls to the "ADD OIL" mark,
add oil immediately. Do not add above
the "FULL" mark. Check your oil
each time you buy gasoline and before
starting long drives. After the initial
change at 500 miles and a second oil
change at 2,000 miles, engine oil should
be drained and replaced every two
months or 2,000 miles, whichever occurs
first. More frequent changes are required
with unusual stop-and-go operation, dusty
road travel or during prolonged cold or
wet climatic conditions. In extreme cases,
your Cadillac Serviceman may recommend
an oil change after 1,000 or even 500 miles
of driving.
Your Cadillac is equipped with an
oil filter that removes harmful particles
from the oil. The element of this filter
should be changed every 6,000 miles.
The engine oil level indicator is on the
left side of the crankcase. The combination
oil filler and crankcase ventilator
cap is in the center of the engine in
front of the carburetor. It is wise to
have the oil level checked each time
gasoline is purchased. Add oil whenever
the level is down to the "ADD OIL"
mark, but add only enough to bring
level up to the "FULL" mark or the
five-quart level. Avoid overfilling crankcase,
since this may cause the oil to
foam. The copper gauze in the ventilator
cap should be cleaned and dipped
in clean oil when the oi! is changed.
