OIL IS POWER,
AUTO TEST
SHOWS
Motor Check Demonstrates
increased Efficiency With
Right Lubricant
By j. PAUL WARD.

Oil is more than oil-it is power.
Here's a new automotive fact
that has caused almost as much
furore in the industry as the intro
duction OF the self-starter, or the
arrival Of the four-wheel brakes.
From the time Of the Get a Horse"
days down to the coming OF the
WATSON Motor Check, that revolu-
tionary invention which completely
tests a car without loosening bolt,
oil has been discussed and what's
more, sold in terms of viscosity,
zero tests, molecules. and what
not.
But no longer, the automobile
manufacturer, dealer, and the car
owner want to know-not what the
viscosity is, nor the results of the
zero test, nor the shade, but in
stead, what power will the oil give.
Just as surely as the self-startsr,
and the foiir-wheel brakes got thar
punches into old man tradition, GO
did the WATSON Motor Check, and
where the K. O.. was delivered was
to the ether in oil sales talk.
What OH Does.
This WATSON Machine brought
the truth about oil right out In
the open-just as il has been doing
in this city for the past several
weeks. 1t has proved to local
motorists that old oil, diluted
through use, Il powerless; that
dirty oil, replenished "a quart at
a time, is powerfess; that cheap oil,
even when fresh, is powerless, and
that too heavy or too light oil,
even of good quality is powerless,
and also that the right grade of
oil in a motor will result in more
power for that motor.
This fact is being demonstrated
daily by the WATSON Motor Check,
at Twelfth and c. streets northwest,
where hundreds Of car owners are
securing free tests, and are having
the oil-power theory proved to
them right in their own motors.
They are learning for the first
time the real truth about their
cars, and are seeing that by using
the right grade of oil a gain in
power from 10 to so per cent will
result.
Method Of Test.
These oil-power tests consist Of
having the car owner drain his
crankcase and fill UP with the
right grade OF Havoline which the
Indian Engineers deem advisable.
Then the car owner runs his car
up on the motor check stand, and
a test Of power Is made from low
speed up to the best that his motor
could do. This is followed by what
is known as the Gasometer test
which depicts the amount Of un-
exploded gasoline which slips by
the pistons causing loss Of power
and dilution.
Additional tests, in order that
the car owner may get a complete
sizeup Of his car, also are included.
These are tests for timing accuracy,
wheel alignment, brake adjustment,
speedometer accuracy, test for slip
ping clutch, etc.
A record Of all tests made is
takcn, and a copy in sample form IS
given the car owner. He Is told
to come back, after he has driven
several hundred miles, for a. second
test. In this test the motorist secs
his gain in horsepower.
So popular have been these tests
in this city that the motor check
engageme has been extended in
order to meet the great demand.
Changing the Viewpoint.
It is the same all over the country.
This oil-power campaign in this city
is only part OF the national educa-
tionat campaign. In Dayton, Harris
burg, New York, Louisville, LeXing-
ton, Chicago. San Diego, st. Paul,
Evansville, and other centers, the
Havoline oil.power tests are being
staged with the same satisfying re-
suits. This campaign is now in its
second year.
Last season more than 10000 car
owners had their engines tested on
the motor check, and now know
really what oil means to a motor.
The consequences are that they
are now judging oil solely in the
power that IT will give. Other terms
