Gear oil of S. A. E. viscosity 160 should be used in the trans-
mission at temperatures above 20° F. For temperatures below
2 0 ° F, a light oil of S. A. E. viscosity 90 should be used or the oil
used during summer weather should be thinned with kerosine.
Some of the lubricants designated by "EP" following their
S. A. E. classification, and some other lubricants which are being
marketed, are injurious to bronze parts and should not be used in
Cadillac cars under any circumstances. Likewise, soap greases
w i l l not satisfactorily lubricate these gears and should not be
used.
R e a r A x l e L u b r i c a n t
Gear lubricant of S. A. E. viscosity 160 should be used in the
rear axle. For extremely low temperatures, it may be necessary
to change to a light lubricant of S. A. E . viscosity 90 or to thin
the lubricant with kerosine as suggested under "Transmission
Lubricants."

The selection of the proper lubricant for the steering gear is of
special importance, particularly to avoid hard steering in cold
weather. A special steering gear lubricant suitable for extreme
heat and cold is available and should be used in the steering gear
the year round.
C h a s s i s L u b r i c a n t
A good grade of chassis lubricant should be used for all chassis
points indicated in the lubrication chart as requiring this type of
lubricant. Ordinary cup grease is not satisfactory and if, in an
emergency, it is used in place of chassis lubricant, the car should
again be lubricated within 300 or 400 miles.
C l u t c h a n d W h e e l B e a r i n g L u b r i c a n t
The front wheel bearings and the clutch release bearingshould
be lubricated with a good grade of Clutch and Wheel Bearing
[141
Lubricant having a high melting point. Ordinary grease at
these points is likely to melt and run on to the brakes or the
clutch.
W a t e r P u m p L u b r i c a n t
A water-resistant calcium soap lubricant having a high melting
point is recommended for use in the water pump grease cup.
Only lubricants of this type should be used; other lubricants will
be dissolved into the cooling system liquid. Cup greases and
wheel bearing lubricants are entirely unsuited for this purpose.

The supply of engine oil is carried in an oil pan at the bottom
of the crankcase and is circulated through the engine by means
