The Indiana State Department of Health filed emergency stop-sale orders against two Marathon gas stations in Indianapolis Thursday after finding too much water in the gas they were selling. The station at 9601 N. College Ave. had water in its premium unleaded gas. The Marathon at 3511 S. Post Road had problems with its regular unleaded fuel. Indiana State Department of Health's Ken Severson said the problem boils down to maintenance at the gas stations and advised drivers who had filled up at the stations in question to have a mechanic check their fuel systems for water. The stop-sale order remains in place until the gas meets state standards.
