In September of 2013, suppliers replaced 87 octane regular unleaded gasoline with 84 octane regular
unleaded gasoline. Regular unleaded gasoline was blended with premium gasoline or ethanol to increase the
octane from 84 to 87.
In 2012, ethanol prices were lower due to high ethanol inventories, and by the end of 2012, ethanol demand
was very strong. Gasoline demand dropped 6 percent in 2012 as more drivers filled up with ethanol–blended
In the spring of 2010, Nebraska was experiencing high corn prices and low petroleum costs.
In the fall of 2009, expectations for a record corn harvest came to
fruition. Corn and ethanol prices felt the impact and were pushed lower. Even with the
expectations and then the actual harvest record, annual consumption of ethanol–blended fuel for 2009
was less than 2008.
Market share increased during 2007 and 2008. In 2007, additional ethanol operating capacity pushed ethanol prices
lower, and in 2008, increases in gasoline prices worked as an incentive for consumers to use an
ethanol–blended fuel. Gasoline prices began to fall, but motorists did not immediately return to
using 100–percent gasoline.
The availability of ethanol–blended fuel, the price at the pump,
and strong demand contributed to the increase in market share in 2005 and 2006.
Annual averages are available. The ethanol section of
the state energy office's energy statistics has more information.
