Everywhere this emblem means ETHYL GASOLINE THE oil companies which supply more than fifty per cent of all the motor fuel used in the United States and Canada are now mixing Ethyl anti knock fluid with their gasoline to provide a premium fuel that is worth a premium. Every one of them has agreed to conform to the standard set by the Ethyl Gasoline Corpora tion. This means that they will use base gasoline of specified quality, and mix with it suf ficient Ethyl fluid to "knock out that 'knock'" in cars of average compression, and to develop the additional power of the new high-compression cars. So wherever you drive whatever the oil company's name or brand associated with it - any pump bearing the Ethyl emblem represents that standard, or better. Remember that while Ethyl Gasoline is colored red for iden tification, not all red gasolines are Ethyl. Always look for the Ethyl trademark. Ethyl Gasoline Corporation, New York City.
