These oils are not suitable for prolonged high speed driving and if used under such conditions the
oil level must be closely watched, as the rate of consumption will be higher than with heavier oik.
"Heavy Duty" Oils
Oils having an S. A. E. viscosity of 40-50-60 will show lower oil consumption for prolonged high
speed driving than the lighter oils which afford easy starting. Some of these heavy oils demonstrate
greater fitness for extreme high speed, due to their meeting certain specifications as to volatility. To
make certain of using an oil suitable for this service, consult your Cadillac dealer.
Heavy duty oils vary in their suitability for winter use. If a heavy duty oil with sufficiently low
cold viscosity is not available and if the car is not kept in a heated garage, the lighter oils specified above
for moderate^riving must be used to avoid hard starting. In this case, be sure to watch the oil level
closely as cautionea above.

SPRINGS AND SHOCK ABSORBERS
General Description
The spring and shock absorber equipment is
very much alike on both Cadillac and LaSalle
cars with the exception of the size and shackling
of the springs and the use of shock absorber control
on the Cadillac models.
SPRINGS
The front springs are of the helical or coil type,
while the rear springs are of the semi-elliptic
type.
The front springs are mounted between the
frame and the lower suspension arms. They have
nothing to do except to spring the car as they are
not depended upon to absorb the steering and
braking stresses. As a result, they can be made
as soft-acting as desired for riding comfort. Large
rubber bumpers are installed inside of the ;
coil
springs to cushion extreme movement and to
assure proper riding comfort.
The rear springs have a rubber and asbestos
composition strip between the eye or No. I leaf
and the No. 2 leaf and graphite bronze plates at
the ends of the remaining leaves on the Cadillac
cars and between the Nos. 2, 3 and 4 leaves on the
LaSalle. The purpose of the composition strip is
to dampen the spring action by decreasing the
liveliness of the spring and to serve as an antisqueak.
The bronze plates in the ends of the
other leaves are for the purpose of providing constant
lubrication to prevent squeaks.
Rubber pads are also used between the rear
springs and the spring perches on the axle housing
on LaSalle cars to insulate against noises.
Spring covers are used on the rear springs.
Pressure fittings are not provided for lubricating
the springs as external lubrication is not required.
