Don't believe everything they say about the ethanol fuel, the ethanol fuel treatment companies will say anything to get you to spend money and buy their product which is mostly alcohol. In some cases that fuel treatment alone can gum up the carb. Ive seen it happen...
Fueltesters and pure-gas have some great info on additives. They break down the main ingredients in each product. Sea Foam, Sta Bil, Starbrite, Lucas, etc and all of them contain some type of alcohol, harsh solvent or even ethanol.
I used to be one of the guys that would put Stabil and Sea Foam into every gas can. I did not do any research and was being stupid. Gas companies spend millions in research and add their own additives to the fuel. If there was something so amazing on the market, the gas companies would already put it in the fuel.
