In May 1986 with the officialization of the PROCONVE - Program for Controlling the Air Pollution by Automotive Vehicles, by the Resolution N°.018/86 issued by the Brazilian Environmental Council - CONAMA (Appendix I), the local auto industry was called to use its creativity, financial and technological capacity, and its best strategic planning to effectively implement this emission control program. At that time, Brazil already had specific scenarios related to fuels used by passenger cars such as the large usage of Hydrated Ethanol - Appendix II, which will be called E100 from now on, and the usage of Gasohol - Appendix III, a blend of gasoline with 22 percent anhydrous ethanol, which will be called E22. This blend, in several locations still had a certain amount of lead, which was completely eliminated only at the beginning of 1992.
