From the EIA: Almost all U.S. gasoline is blended with 10% ethanol
Next, are two paragraphs contained in the report.
Blends of petroleum-based gasoline with 10% ethanol, commonly referred to as E10, account for more than 95% of the fuel consumed in motor vehicles with gasoline engines. Ethanol-blended fuels are one pathway to compliance with elements of the federal renewable fuel standard (RFS). The total volume of ethanol blended into motor fuels used in the United States has continued to increase since 2010, albeit at a declining rate of growth. Meanwhile, the use of ethanol-free gasoline (E0) by fuel consumers has declined.
Domestic disposition of E0, calculated as domestic production plus inventory withdrawals plus net trade (imports minus exports), was 494,000 b/d (7.6 billion gallons) in 2015. However, actual use of E0 in vehicles, boats, and other equipment with gasoline-burning engines was likely below that level because some volumes of E0 that enter the domestic market may have been blended with ethanol at smaller terminals that are out of scope for EIA reporting or blended at the point of retail sale.
