Re: mandated ethanol
Evinrude and Johnson outboards have been manufactured to run on 10% alcohol blended fuels since 1990. There is alot of scepticism regarding this. I hate to say it but if you live in Texas you dont have many other options!The key thing to understand about ethanol is that it is soluble in water.<br />This means that water and ethanol mix freely, whereas water and gasoline do not mix - they are insoluble, meaning that gasoline and water remain in separate 'phases' when they are in contact with each other - including in the UST's beneath your favorite gas station. The gas typically floats on top of any water and sludge accumulated in the bottom of the tanks.<br />(This is also why you may have heard it's never a good idea to buy your gasoline at a station when the fuel supply truck is there filling up the tanks. The high speed pumping of the fresh gas into the UST stirs up the bottom sediment and water (BS&W) which can then end up in your gas tank.)<br /><br />Right now, the industry seems fairly united in their recognition that as little as one-half of one percent (0.5%) of water in a UST will cause "serious phase separation with the ethanol gasoline blend". Folks, that's not much water. And whereas that water used to sit idly by in the bottom of a UST, it's now going to mix freely with the ethanol gasoline on its way to your gas tank and motor! ??GOOD THING??
