The "ethy" was the short name for gasoline that contained Tetra-Ethyl Lead. This product was an additive to gasoline to boost the octane. The Ethyl Corporation [they had a big plant in Baton Rouge] and Dupont were the main suppliers, but it was very very toxic and environmentally unfriendly.
Putting "lead" in gasoline was phased out back in the 80's [I think].
