They they might have to sell 10% but that doesn't mean they can only sell at least 10%.Not to get all technical and stuff, but it is a Federal law (EPA) that all gas stations must sell at least 10% ethanol fuel for on- road use only. Similar to diesel fuel. It is illegal to run non-ethanol fuel in on- road vehicles. A law passed in I believe 2018 that required stations to sell 15% ethanol depending on some weird formula of supply/demand. I can find if anyone really cares. Ethanol fuel is supposed to be used within 2 months of coming from the station, it also suffers from what is called "phase separation" meaning the water separates from the fuel ethanol mix. Water is heavier than gas or ethanol so it sits on the bottom and is the first thing that goes into your carb. We know the only thing that burns water is a Stanley Steamer. You also must be aware that ethanol is "hygroscopic" meaning it absorbs water from the air, so your 10% ethanol you bought 4 months ago may be 15-20% higher in water content than what it started life as. As a career small engine mechanic for the last forty years, I have had my share of fuel related repairs. Oy, you got me started preaching.
Iowa gov is wanting to pass some stupid thing that all but one pump at a gas station must sell at least E15.
My tractors suck off the bottom of the tank, they dislike ethanol in varying degrees.
I can still get straight gas in 87 octane, I like really having the option.
