The Federal Trade Commission has announced final amendments to its Fuel Rating Rule. The Rule determines the fuel rating that appears on fuel pump labels, and how octane levels are calculated.
The final amendments require that fuel marketers rate and certify all ethanol blends with ethanol content ranging from above 10 percent to 83 percent. They also require that retailers post labels with ethanol percentage disclosures and with the statement: “Use only in Flex-Fuel Vehicles/May Harm Other Engines.” They do not adopt the alternative method of determining the octane rating of gasoline.
In April 2014, the Commission published a Notice of Proposed Rulemaking seeking public comment on new rating, certification, and labeling requirements for gasoline blends with more than 10 percent ethanol, known as ethanol blends; and an alternative method to determine the octane rating of gasoline, which is known as infrared spectrophotometry.
The Commission voted to approve the Federal Register Notice announcing the final amendments was 4-0.
