High-Octane Fuels Act: Cleaner Engines and Higher Efficiency by 2028.

This law mandates the use of higher octane (95 RON, later 98 RON) and higher ethanol blend fuels (up to 25% or 30%) for new vehicles starting with the 2028 model year. The goal is to boost engine efficiency, reduce carbon emissions, and improve air quality by limiting harmful components in gasoline. Consumers buying new cars will need to use these higher-standard fuels, which retailers must gradually make available nationwide.
Key points
New vehicles (starting 2028) must be designed for and warrantied to use minimum 95 RON gasoline (and 98 RON starting 2033) blended with up to 25% or 30% ethanol.
Large gas stations must begin offering 95 RON gasoline by 2027 and 98 RON gasoline by 2032, increasing the availability of these higher-performance fuels.
The law introduces limits on harmful aromatic hydrocarbons in gasoline and requires octane boosters to have significantly lower lifecycle greenhouse gas emissions, aiming for cleaner air.
