fuel additives for winter storage?

If you have the time and the desire you can get gas with the ethanol and add water to it. Shake it up and the ethanol goes to the water. Then freeze it in batches and remove the ice which contains the alcohol. Or try and pour it off. Then you are left with just gasoline....... Don't have the patience or the room to try and do it. Others out there have done it there are threads about it on the net. I just prefer to treat the gas with MMO or Auto tranny fluid in the proper amount. I have seen others use sea foam with success also but for me I buy the MMO gallon container rather cheaply and refill a bottle I keep in the trunk.


Marvel Mystery Oil was developed back in 1923 or so to fight the build up of sludge in carbs on the armed forces airplanes. They used to get it in 55 gallon drums to treat the fuel. It's was first developed and designed for helping with fuel issues. As a carb that craps out or stalls out at 10,000 feet or more is a bad situation.
