The percentage in mass of the oxygen in oxygenated gasolines in Argentina has averaged 3.3% m/m in the study period, below the maximum regulatory limit of 3.7% m/m between 2010 and March 2016. 26 samples did not comply with this regulatory limit. A maximum of 4.5% m/m was found from April 2016 onwards, with 69 non-compliant samples. In 2022, however, 50% of the samples did not comply with the regulatory limit.
