Next Generation Fuels Act of 2023

The Next Generation Fuels Act of 2023 requires automotive manufacturers to design vehicles (starting with 2028 models) to operate with gasoline containing 10-25% ethanol (with 95+ research octane) and later 10-30% ethanol (with 98+ octane). It mandates fuel retailers to offer 95+ octane gasoline at certain outlets by 2027 and 98+ by 2032, with specific availability requirements for different retail outlet sizes. The bill also requires clear labeling at fuel pumps and on vehicles to inform consumers about fuel requirements and consequences of using lower-octane fuels. Additionally, it establishes new standards for gasoline composition, including limits on aromatic content and requirements for low-carbon octane additives.
