The addition of ethanol is a legal obligation for fuel distributors. Law No. 8723 of 1993 provides for the addition of anhydrous alcohol to gasoline. A few years later, new regulations changed the percentage of the mixture. Since March 2015, the mandatory percentage of anhydrous ethanol in regular gasoline is 27%. The share of premium gasoline is 25%.
