Proposed Chicago E15 Ordinance

The Chicago City Council is considering an ordinance which would mandate that many gas stations in Chicago distribute E15 gasoline (15% ethanol). Although a City Council Committee passed the ordinance, Mayor Emmanuel asked that the vote on the measure before the full Council be delayed for additional research.

E15 is not approved for use in marine engines, small engines and the majority of cars on the road. Since a majority of our boat owners fill up at roadside gas stations, this ordinance increases the chance for dangerous misfueling and puts the ethanol industry before consumer safety.

Please stay tuned for updates on this issue.
