ENGINE WEAR
GREATLY GUT
BY TRITON OIL

Triton motor oil, Union Oil COM
pany's 100 per cent pure paraffin-
base lubricant which is being man
ufactured from western crudes by
the propane solvent process, reduces
engine wear from % to 43 per cent,
according TO a statement made re-
Gently by E. w. Hutton, manager
lubricants and special products de-
partment, Union Oil company.
The bases for the declaration,
Hutton said, are results obtained
from comparative dynamomeJer
laboratory engine tests in which
Triton was checked with high grade
eastern and high grade western
oils. In a series of experiments to
determine the relative wear, it was
found that with Tritno engine wear
was reduced % per cent over that
which occurred when eastern type
oil was examined and 43 per cent
over that which occurred when the
western type lubricant was used.
The Iron content" test by which
engine wear is determined was de-
vised by Howard H. Langdon, head
of the department of mechanical
engineering, Washington State col
lege. BY weighing the metal par
ticles which are contained in an oil
which has been in service for a CIV
en- period, rate of wear in terms
of pounds of iron per unit miles
operated may be computed.

uents in a motor oil which it is be-

the low grade oils-in the exclusive
propane solvent manufacturing pro-
cess. Hutton explained as the reas-
on why engine wear is reduced
with Triton. The carbogens have
an A. P. I. gravity Of from 5 TO
IS l.O37 10 0966 specific gravity
and are literally carbon formers;
J they are unstable materials which

likewise unstable, low grade oils
with an A.PI. gravity Of from Is 70
, 20 CO.966 to 0934 specific gravity

To accurately gauge the effects

ton stock. were used IL a dynamo
meter engine test. When running
with carbogens, the engine began
to sludge up almost Immediately
and within a short time it was nee
essarv to shut down in order TO pre-
serve the motor. When running
with naphthenes, rate of wear in
creased several times as compared
with that experienced with Triton
Confirmation of Triton's ability
to reduce engine wear was found Il
$4,000 mile road test run in 81
days with a 1884 Studebaker. Car

hours a day, the car sped over Pa

the run, when the motor was agaiI
torn down and micrometer reading
taken, it was found that engin
wear was less than half that nor
mally anticipated for $4,000 mile
of driving. A. E. Hunt, Studebake
