Two South Dakota companies have been charged in Beadle County with selling gasoline with mislabeled octane levels.
Beadle County State's Attorney Michael Moore says M.G. Oil Co. of Rapid City has been charged with illegally selling 85-octane gasoline and mislabeling gasoline at its five stations in Huron. He says 281 Travel Center in Wolsey has been charged with mislabeling the gasoline it bought from M.G. Oil.
The charges are Class 2 misdemeanors carrying a maximum penalty of a $500 fine and 30 days in jail.
A representative of M.G. Oil did not immediately return a phone call seeking comment.
A state investigation found some stations were selling 85-octane gasoline mislabeled as higher octane gasoline. A new state rule also allows 85-octane gas to be sold only in western South Dakota.
