The Federal Trade Commission (FTC) has amended its Fuel Rating Rule (prescribing labeling requirements on fuel dispensers) as it pertains to gasoline-ethanol blends with greater than 10 volume percent ethanol (E10). The rule is generally designed to update the requirements to accommodate the sale of ethanol blends between E10 and E85 (such as E15). The amendments do not alter the current labeling requirements for E10, diesel, biodiesel, or biomass-based diesel.
The FTC's Rating Rule governs the fuel rating that appears on dispenser labels and how octane levels are calculated. The rule generally requires fuel retailers to post a notice on the dispenser indicating a fuel's octane ratings or cetane ratings (for diesel fuel).
