13 What do these anti-friction surfaces that
you have mentioned consist OFF"
They are surfaces produced by covering the metals

ana with 1t you have the strength of the metal plus
the lubrcating value of pure graphite"
IA. VIII not the graphite be quickly removed
when the metals rub each other?'
Mo; It is held in most remarkable manner. Ia a
test made under the supervision of expert engineers
1t was found it required two and one-half hours
remove graphoid surfaces when of them were
square inch while being violently rubbed This test
was made with the surfaces in dry condition. oil
or other liquid being present.
Is. This is a wonderful demonstration, but it
probably made under laboratory con-
ditions, was it not?"
yes, it was, but it has become common occurrence
to hear of an automobile running ordinary roads
for distances of from IS to 90 miles without any oil

For the formation of the .graphod surfaces car

graphite, in the oil of which the Oldag is made is
oil that is to say one pound of graphite in every
tour hundred ID pounds OF oil It requires time for
coating, and only then the graphoid surfaces

II. S'Are there no benefits resulting from the
use of Oildag until the has run this long
distance?'
YES, you will begin notice improvement very
soon perhaps after 20 30 miles but maximum,
eHect is not obtained until the graphoid surfaces
completely formed"
49, Cam these graphoid surfaces be produced
with any graphite, for instance such as is
dug from the ground, the small fakes
found in some rocks ?''
The graphite must be in the molecular condition in
order that the molecular forces may come into play
and hold 1t firmly the metal Graphite in
this condition is not to be found the worlds

dag Company"

results from my if used Oiidag lubri-
cation in the engine %
i am quite sure would, provided the engine is in
proper condition when you commence it,
20. What do you mean by being in proper con-
dition?"
Perhaps it may be said without error that all cars
which have been operated while using ordinary oil
lubrlcatIon have more or less carbon deposits in
them If the amount of carbon deposits in the cyn-
ders and in the piston ring is very great
and it will be blown out from the exhaust If, the

Il. IL costs money to have carbon removed.
Is it worth t?''
at certainly is in your case You have invested
good deal of money in your you certainly
want to get the best results, and prolong its life
few dollars will the cost of removing the
carbon and you will much than this cost

%. 'Ts Oildag as thick and viscous as the oil
using, which | am told has WIS.,
costly of 600 to 7OO?"
NO, 1t is not nearly SO viscous There are several
grades in use, but the thickes not more than 500
viscosity Thick oils waste good deal of the power
of the engine
% DO not these thin oils get past the piston
rings INTO the combustion chamber and pro-
duce carbon deposits?''
NO; the graphoid surfaces, permitting free action
allow the rings to expand to the cylinder walls and
on their downward stroke all excess Oildag which
may have been splashed otherwise spread over
the cylinder walls, is wiped into the case The
condition you suggest has occurred however in
cases where autoists who familiar with the
