Ethanol is evil.
I have a friend who owns a landscaping business. She pays the exorbitant price for E-Zero gas for all her small engines. She figured out the extra being paid was less than paying small engine repair shops to fix her engines. Machine downtime is very expensive for her.
You can remove ethanol from gasoline with a bit of water and separatory funnel. You can get a 6 liter one on Amazon.
