Fuel specifications


Northern-grade RFG is required in Chicago area counties including Cook, Du Page, Grundy (Aux Sable and Goose Lake Townships only), Kane, Kendall (Oswego Township only), Lake, McHenry, and Will, and East St. Louis area counties of Jersey, Madison, Monroe and St. Clair. Conventional gasoline is sold in remaining counties in the state.

Reid Vapor Pressure:

Counties not in RFG program areas require 9.0 psi RVP gasoline June 1-September 15. Madison, Monroe and St. Clair counties use 7.2 psi RVP gasoline from June 1-September 15.  These three counties plus Jersey County opted into the RFG program in 2007. Illinois’ most recent State Implementation Plan removed the 7.2 psi RVP requirement from those areas, but EPA has not approved the SIP as of the date of this publication.
