The other recent development OF

sign is the Skinner system Of recti-

While many motorists appreciate

crank case oil frequently, 1t IL
doubtful it many of them correct

| done. The primary reason for
| changing crank case oil is. not, as
many people may think, because 1t

| oil is worn out quickly In the opera
ton Of the motor.
The Real Reason
The reason that motor car manu-.
| facturers, oil companies, garages.
service stations and repair shops
continually urge owners to change
their crank case oil every 500 miles
| Is because the oil has been thinned
down after that much running by
gasoline, water and harmful acid
solutions which In the past it has
been impossible to exclude from the
crank case.
Modern, heavy fuel permits an I'M

tile elements to leak down past the
piston rings and dilute the crank
case oil, destroying it's lubricating
qualities.
Until Ralph L. Skinner with the
aid and cooperation Of Packard IA
cilities and Packard engineers per-
| fected the Skinner rectifier and the
Skinner system of preventing crank
case dilution there seemed no way
to stop this harmful process.
! Now, by ingeniously using the
vacuum in the intake manifold to
draw off from the pistons them

case--that harmful mixture of acids,
Oil and gasoline, the Skinner system
| deposits it in what may be termed
small still or "rectifier."
No Waste Permitted
| There under vacuum the heat OF
the exhaust is used to remove the
more volatile elements from the Oil
before it is returned purified to the
crank case. The gasoline, separated
from the lubricant is not wasted. 1t

AS a result of these highly i'm
portant improvements the manufac-
turer Of fine cars today is able to
deliver a car not only well designed
and well built but which is well
equipped to deliver first-class trans
portation with a minimum of atten, |
