DTN U.S. Gasoline Markets Shift to Higher RVP Specs Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- DTN gasoline assessments will reflect higher Reid Vapor Pressure (RVP) specifications starting Tuesday (9/1), as fall seasonal blending changes took effect. In the Chicago and Midwest markets, CBOB Regular, RBOB Regular, Premium Gasoline and RBOB Premium transitioned to 11.5 RVP. In Group 3, sub-octane and premium gasoline transitioned to 10.0 RVP, replacing the previous lower-RVP summer specification. On the U.S. Gulf Coast, CBOB Regular, Premium CBOB, conventional Regular and conventional Premium gasoline transitioned to 11.5 RVP. RBOB and Premium RBOB transitioned separately to 13.5 RVP. The seasonal shifts reflect the move toward more volatile gasoline specifications as temperatures cool heading into the fall and winter demand season. These RVP changes should be considered when comparing day-to-day cash differentials, as part of an apparent price move may reflect a change in the product specification being assessed rather than an actual move in the underlying physical market.
