Wherever internal combustion en-
gines are used-in automobiles, motor
trucks, afrplanes, tractors, and so on
their performance and durability de-
pend entirely upon their fabrication.
Leading engineers, after hundreds Of
careful and costly scientific expert
ments, have determined that the ma
Jority q engine troubles are directly
due to defects in keeping the recipro-
eating parts properly oiled.
The Importance OF this problem in
engine design and operation, and
most vital of all-in refining lubrica-
ting oil, has led automobile and en-
CINE builders to conduct constant re-
search work to determine the most
practical construction.
One oil refining company has kept
pace with fhe automobile and engine
builders in this work for the advance
ment OF lubricating methods. The
Platt & washburn Refining Company.
Of New York erected a large special
laboratory, deliberately equipped, to
determine the exact service efficiency
of oils in various types of gasolene
engines, transmissions, etc.
.. All Types are Tested.
In this laboratory all types OF in
ternal combustion engines are tested
under actual service conditions, SINH
lar to those met with on the road, and
the results are recorded by sensitive
and accurate apparatus. Veedol, the
Platt and Washburn oil, as well as
oils produced by other leading re
timers, are thus tried out in practical
service and the results are scientific
ally recorded. The collection of all
this information enables the engineer
ing staff to logically specify a GER
tain grade OF oil for any lubricating
system to provide maximum service
and economy.
Bearing out the opinions of the au-
tomobile and engine designers, these
experiments showed that when the
engines we're operated with ordinary
lubricating oil, trouble developed
quickly and required frequently.
=. hen the. proper grade OF oil was used
under the same conditions these n
gines exhibited a remarkably smooth,
powerful performance and troubles
were practically eliminated
LubrieatinE Value Impaired.
No oil now made can stand up In
definitely under the terrific heat of
an automobile engine. Many oils
form black sediment after a few
hours use, and their lubricating value
Is impaired to such an extent that
wear soon becomes rapid.
Within the explosive chamber and
on the piston head heavy deposits of
carbon frequently accumulate when
ordinary oil is used. Oils which sedi.
mentize rapidly form the most vo-
luminous deposits. This carbon
causes pre-ignition by projecting par.
ticles becoming white-hot and IgnIt.
ing the gas before the piston has com.
pleted its up-stroke. This causes
knocking, which is a symptom Of tire
mendous wearing strain imposed on
the entire engine.
Remarkable Variation.
There is a remarkable variation in
the amount OF oil destroyed by heat
when lubricants of different quality
and suitability are used, even though
the tests are run in the same engine
and under identical operating condI-
lions. This Is shown by the amount of
black sediment that settles out of
each after standing for a time. The
oil floating above the solid sediment
is red in color by transmitted light,
and may be assumed to be equally as
serviceable as when fresh. Two fac
tors determine the rapidly with
which oil is destroyed by heat-its
chemical purity and its chemical sta
bility.
