I guess you would have had to been there when a fuel contamination mass casualty event occurs, because this is the result. It happened in 2004~2006 or so in the Sea-Tac area when the Phillips Petroleum refinery north of Seattle goofed and blended "too much polymer" in the fuel and it gummed up and stalled hundreds of cars as far south on the pipeline as Olympia was the official news release, but I know some of it got to Portland because gas bought at Chevron stations over a several day period knocked like crazy and small engines, mowers, blowers, weed whips, etc, would not start until the fuel was changed with fresh fuel from another source. Phillips paid the bill on that one too. "If you bought gas from our 76 stations in the Sea-Tac area on ?x? days and your car stalled, have it towed to your dealer and we will pay the repair bill." No joke.
