Wandering around in Walmart I found something that may interest you. STA-BIL, Ethanol Treatment. It says it prevents corrosion caused by Ethanol fuels in vehicles and small engines. Effective in ALL Ethanol Blends to E-85. Its in the automotive dept and is a 10 oz bottle for about $7.80 and treats up to 25 gallons. Since we have had a big discussion earlier about ethanol and its effects on metal surfaces, maybe this is something we can use to circumvent the growing ethanol invasion. I got some and used it on our 10% blend here. I guess time will tell if it works or not. Just some information for those who might want it.
