The Fuel has 10-30% ethanol in it from the pumps. This will immediately start to absorb the moisture from the air. The ethanol sucks it up and within one week phase seperation starts.
The water settles to the bottom of the tank. After three weeks the fuel then starts to loose its octane rating.
After 6 weeks it starts to damage and corrode carb parts.
Your gas can should be sealed and treated with a product called K100= Available on line and at certain Advance Auto Stores. You can not over dose with this product.
It will stop all phase seperation and literaly absorbs then burns water. You Stable people before you get on your band wagon I want you to get a glass jar pour in some water pour in your Stable or Star Tron shake it up and watch what happens.
Not pretty but it does bring you back to the Lava Lamp days. Try the same thing with K100- A picture is worth a hundred words. I am not a dealer for K100. But I have extensive field testing with this product in Diesel, Power Sports Small engines and the Boating Industry.
Unless you folks can find Marina Gas or Small Engine Fuel with no ethanol in it. Then some Stable is all you need. Ethanol is not in this fuel
