1938 Cadillac V16 - GM Heritage Center

the oil is reduced and oil consumption increases under
wide variances in temperature.
The compactness of V-type design also permits a
greater water cooling area around cylinders and valves.
Because of the great length of a straight eight engine,
which must be fitted into a limited space, water areas
must be restricted in size and cooling efficiency is lost.
V-type design lends itself admirably to efficient cooling
system operation with resultant operating economies
and longer engine life.
Efficient
Lubrication
Three large main bearings each have greater surface
area, hence retain oil longer and are easier to lubricate
than any one of the seven or nine small bearings of the
eight-in-line crankshaft;
There are other lubrication advantages inherent in
V-type design. Oil conduits throughout the engine are
shorter, reducing danger of plugged oil passages. Oil
is directed under pressure through drilled holes in the
crankcase-removing the danger of engine failure from
broken oil lines where a piping system is used.
Due to the shortness of the V-8 crankcase, positive
