EIA: Growing octane needs widen price spread between premium, regular gasoline

In late 2016, the difference between US average retail prices for premium and regular gasoline reached 50 cents/gal. This price spread has been generally expanding since 2000, and the rate at which the spread has grown has accelerated over the past 3 yr. Many factors on both the supply and demand sides are likely influencing this trend.

Calculate gasoline RVP seasonal change giveaway economics

Barsamian, A., Curcio, L. E., Refinery Automation Institute, LLC

Despite high demand and depressed refining margins, the US is in the midst of a glut of gasoline. This predicament is causing a rush to convert summer gasoline into cheaper winter gasoline, in the hope that using cheap butane and higher Reid vapor pressure (RVP) specs will increase refining profits.
