A long-trusted substance that can be poured into your engine to smooth out rough idling, hesitations, run-on, and other ills, Sea Foam has gained national prominence since it was developed more than 50 years ago, originally for the marine market (an early customer was Milwaukee’s Evinrude Outboard Motors). Still, even local users are probably unaware that its maker, Sea Foam Sales Company, is based in Eden Prairie.
