There was news in my area about a month ago that Marathon gas stations had received gasoline with a higher ratio of ethanol than normal. They never said how much more but Marathon posted several advertisements on radio, TV and newspapers with warnings that the fuel could damage small engines. They were instructing customers to return the fuel and not use it in lawnmowers, weedeaters and the like. I don’t use Marathon gas but have heard of several people who had “water in the gas” type symptoms when using Marathon gas in their vehicles. Speedway gas was also affected.
