So, how is it better than the previously mentioned $12 ethanol free gas at Home Depot or Lowe's? What is that 45% crap in the fuel? Come on...Stihl dealers sell a stihl Moto mix. It's 93 octane with 50:1 synthetic oil. It comes in several sizes and the gallon costs over $31 and they sell a lot of it, even here where non ethanol is readily available at many places from 87 to 93, reasonable priced. The Moto mix is much better than just non ethanol, it's 99% pure gas, the best pump gas in the United States is 55% good stuff and 45% crap that will burn and produce power but will turn into gum and varnish if left to sit long enough. It has a shelf life of 10 years until you open the can , it's packaged with nitrogen,,no oxygen.Moto mix will evaporate,except for the oil mixed with it, and it doesn't contain the crap that causes gum and varnish.$31 is a lot but how much does a new carb cost? How many carbs could you "winterize" with one gallon? If I had a generator that was critical for it to run maybe once every two years,I would keep it full of something that it is completely impossible to cause gum and varnish. Run anything you want but when I store my stuff, chainsaw,weed eater, generator,outboard motor,snow blower,lawn mower, it's worth it to me to put stuff in it that won't ever cause problems. I ride my bike almost every day of the year so it's always cheap stuff for it.
