Importance of Good
Lubricants Emphasized

Few sales OF automobiles are made
nowadays, in the course of which
the buyer does not ask some very per-
tlnent questions regarding the cost of
upkeep, tires, gasoline, and OIL" de-
clares b. c. Ensminger, local distrib-
utor Of the bort Motor cars.
"More's the pity, that the moment
he gets his car, he forgets most of
his former caution and proceeds to
let his upkeep cost run from so per
cent. to 75 per cent. higher than is
necessary. The purchase of tires and
gasoline is popularity supposed to drain
the purse of the motorist, but any mo-
tor car manufacturer will tell you 9TH
erwise, and he has the figures before
him. The facts are that three-fourths
OF the upkeep cost of automobiles to-
day can be directly traced to the
carelessness of owners in keeping their
cars properly fabricated"
AS Mr.. Ensminger sees it, the i'm
portance of buying top-quality lubri-
eating oil cannot be overestimated.
Ten dollars" he states, will probab-
ly pay for the best that the average
car will require in a year, about half
Of this in the case of the bort. The
better the oil is the farther 1t will go.
A temporary saving of two or three
dollars in the purchase of q cheap
OIL and these oils are offered to the
motorist from every street corner,
often results in repair bill of a hun
dred dollars" We are accustomed to
think of oil lubricating, because it is
slippery and few of us stop to think
further on the subject. If we did the
differences in one oil from another
would come more forcibly to our at
tention, and more of us would see the
point"
Look at two highly polished bearing
surfaces under q microscope and YOU
will be astonished at their roughness.
Take these two surfaces and rub
them one over the other, reproducing
the conditions that exist in your
engine. As the pressure of your rub
from friction, they will move harder
and harder, and develop a tendency
to cling together or Seize" as the
mechanic puts 1t. Now place between
these same surfaces several steel ball
bearings. Friction is at once mar
velously reduced and the surfaces
move over one another with as
founding ease.
Substitute for the steel balls a film
of lubricating oil and the same ef
feet is obtained, for the lubricating oil
is in reality composed of countless,
globules, which serve the same
purpose as the steel balls. They keep
the bearing surfaces apart and slip and
slide by one another easily
Suppose the steel balls used in the
above test became Clipped. They
would at once cease to perform their
function properly. Just so 1t is with
the minute globules of which oil is
composed. The heat and pressure to
which the oil is subjected, splits up
some OF 1t, an injury that is both ply
sical and chemical in character. Most
of the broken down oil is burned with
the fuel, but what remains is carbon
This is fine black dust, that per-
meates the oil, turning it black This
dust has the same action on the in
side of the motor as fine sand, and
does most of the mischief. According
to the quality of the oil used, the for
nation of this carbon dust is fast or
slow, and consequently the use of the
very best grades of oil, where this for
nation is slowest. and the frequent
draining out of the old oil and replac-
ing with new, is requisite, If you would
cut down the upReep of your car from
fifty to seventy-five per cent.
