The Birmingham age-herald., 1924-09-14


 bile as the stethoscope does about the human body, will be brought to Bir- mingham the coming week for the first time by the General Oil Corporation, manufacturers of Go-Zip, in co-opera- tionl with the Indian Refining company. This astonishing apparatus which is reported to diagnose motor ailments with uncanny precision, will be seen in operation at the Go-Zip filling station, Avenue c and Twenty-fourth street, south, beginning Monday.
 For the past week officials of the General Oil Corporation have been busily /engaged erecting the Metor Check stand and making provision to handle the throngs of>visitors who are expected to witness its performances. Wherever exhibited in the larger cities, the Wasson Motor Check has proved a source of intense interest to automobile owners.
 "We are extremely fortunate in se- curing this invention for Birmingham" says MT. Gregory Johnston, president of the General Oil Corporation. What the X-ray is to medical science, the Wasson Motor Check-invention of the noted automotive engineer, R. w. Was son, of Newark, N. J., is to the auto motive industry. Without loosening bolt, this apparatus tests with deadly accuracy every running part of a car. All that car owner has to do is to drive his car onto the Motor Check stand at the Go-Zip service station, Avenue G and Twenty-fourth street, south, and in jiffy this Wasson ma chine tells him what his car can ac- tually do in horsepower; how much un- exploded charge is slipping by his pis- tons; what shape his rings are in; whether he is using the right grade of oil: what his gas consumption is and other motor ailments. In short the Wasson Motor Check is here in Bir- mingham to tell automobile owners the exact conditions of their cars-the truth and nothing but the truth. Every motorist in Birmingham is invited to come and have his car checked without cost"
 The Wasson Motor Check is the property of the Indian Refining com pany, which was the first large organi- zation to see the peculiar value of this machine, and which is now introducing the Wasson Motor Check to various cities throughout the country as part of a national educational cam paign to prove to the motorist that oil is more than a lubricant-that it has a vital relation to power.
 This power idea" in oil which the Indian Refining company has added to the automotive vocabulary is the direct result of the Wasson Motor Check. Un- til one day last fall, oil was discussed and had been discussed since the days of Moses-in terms of ''visosity," body" high temperature" ct al. On the day in question, R. W. Wasson, the noted automotive engineer of New ark, N. J., was experimenting with his new invention--the Motor Check, and it was suddenly proved to him by the Mo- tor Check that oil was more than mere ly lubricant, but was a power &C., celerator. Hearing of this scientific automotive discovery, the Indian Re fining company, sent to Newark, some of their engineers, who after a demon stration recommended that the Indian Refining company secure the oil-test- ing rights to the Wasson invention.
 One of the first Wasson Motor Check was installed at the Indian Refinery, Lawrenceville, III. Here for months, the Indian engineers under the super vision of J. E. Lockhart, the noted oil chemist, experimented with all sorts of cars and all kinds of oils, under all sorts of running conditions.
 When they had proved after hun dreds of tests that the right oil seally means more power to motor, the In- dian company decided to launch na- tional educational campaign to prove not that their product, Havoline, was the best on the market, or to discredit any other oil, but simply to show the motorist of the country, that by using the right oil for, his motor, and by ob- serving a regular changing period, he would get more power out of his motor.
 And to prove all this to him not by the old general way of fabrication charts, literature, ct al., but by a demonstration in his own car.
 At the testing station, the motorist has his crankcase drained and flushed. It is filled with the grade of oil which the engineers conducting the test deem right for the motor of his car. A power test is taken to show the exact horse power develops at the rear wheels from low speed to the best she can do. Then gasometer test is, taken to show the amount of slippage of unexploded gaso- line past his pistons, causing loss of power and dilution of oil. A record sheet is made and given to the motorist.
 Then after the car owner has driven a few hundred miles, he is invited to come back for a second test to show how the oil is holding the power. The engineer conducting the test then gives the motorist specific recommendations for his car, showing what grade of oil is best suited for his car as is, and how often he should change the oil in his crankcase. It's a real oil prescription.
