In Washington, the EIA says that the roughly 30 cent spread between premium and regular gasoline is a result of ethanol prices, a spread that has held roughly static since the end of 2012. That spread is lower than it has been in the past because ethanol blending creates cheaper octane blendstock. In 2009 it was about 6% compared to 17% in 2001. Gasoline prices are roughly 25 cents a gallon cheaper now than a year ago.
