RACING car drivers can't take a chance with their engines. Before a race they test their cars with the best gasoline obtainable. Then they add "Ethyl" fluid-the anti-knock com pound-to develop the last ounce of power for speed and safety. Similarly, leading oil companies are adding "Ethyl"fluid to the gasoline pro duced for the general motoring public, What Ethyl Gasoline is ETHYL GASOLINE was de veloped by General Motors re search to provide a more efficient fuel for internal combustion engines. It is formed by adding Ethyl brand of anti-knock compound ("Ethyl" fluid) to selected motor gasoline in an amount sufficient to utilize the higher compression created by car bon deposits or advanced engine design. "Ethyl" fluid is a concentrated liquid containing tetraethyl lead which has the property of controlling the combustion rate of gasoline. It is a patented product. Ethyl Gasoline is colored red for identification. The color has nothing whatever to do with its performance. It takes more than dye to make "anti-knock" gasoline. Ethyl Gasoline is sold only at pumps which display the "Ethyl" trademark. Ethyl Gasoline is the yardstick by which other gasolines are measured. so that your car too may increase its per formance under all driving conditions. This fuel is called Ethyl Gasoline and is sold at pumps which display the emblem shown below. Read the facts about Ethyl Gasoline given below. Remember that even the best gasolines become better when "Ethyl" fluid is added. ETHYL GASOLINE CORPORATION 25 Broadway, New York City 56 Church St., Toronto, Can. WhatEthyl Gasoline does If your car is designed to operate on ordinary gasoline, the useof Ethyl Gasoline will: Eliminate "that knock" and power loss. Make carbon deposits a source ofextra power. For carbon increases compres sion and Ethyl Gasoline is the high compressionfuel. Give a smoother and better pulling engine. Reduce gear-shiftingandincreaseaccel eration, thereby making trafic driving easier. Cut down vibration, thereby reducing engine wear and tear and depreciation. Save you the expense of carbon re moval and other repairs caused by "knocking" and carbonformation. Give more power per gallon for your fuel bills-and more mileage as com pression is increased by carbon deposits. If your car is a high compression car, just remember that Ethyl made it possible and is necessary to obtain maximum performance.
