U.S. Ethanol in Gasoline 2016

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.

  1. Those two graphs, in my opinion, aren't rigorous enough to the topic.

    Part of the 'real topic' is about Physics. The physical sciences including physics, states plainly and without any ambiguity, that ethanol in fuel results in lowering of BTU's generated. It's BTU's that are responsible for work being done.

    Until physics changes, which I say with tongue-in-cheek, I'm anti-ethanol.

  2. The interesting thing here is that ethanol is in almost all of our gasoline. In the past I remember being able to buy gas without ethanol in Nebraska (you still can) whereas gas without ethanol in the metro Denver area was illegal. At least now, I think states like Iowa and Nebraska are using more of it themselves. How much E85 and E15 are being consumed by free choice - I know state governments often mandate its use in government vehicles.
