As many of you know, I have a British car hobby and own a couple of them. Ethanol is a major problem for stored older cars. It does bad things to tanks, fuel pumps, hoses,etc . As a result, many articles have come out on how to deal with this stuff,including products to help stabilize it before it goes into phase separation.
I read an excellent article called "The Ethanol Issue" in my British Motoring magazine. At the end of the article it said to check out the Moss tech video on Dealing With Ethanol at[url=mossmotors.com]mossmotors.com[/url]. I was not able to locate the video on the web site but did find an excellent article there about ethanol under "products."It pretty well summarizes the effects of ethanol, fuel life prior to phase seperation,and of course their recommended products to combat it. Well worth reading.
I, like Lowell, have my doubts about this "snake oil" but am willing to try it. Rotax does recommend a stabilizer in the fuel (at least the school did) I have some different products that claim to help keep the water/alcohol in solution and will probably run an unscientific test on them to see if in fact the stuff works. I did that with POR 15 paint vs Eastwood rust block,Ospho,etc in the past.
The bottom line for me is that I really don't want to drain the fuel out of my tanks after I fly it. This is a major pain in the b--tt! I will of course, if I have too.

Any natural rubber in your system will be susceptible to being eaten by ethanol. I think it is butyrate rubbers that are totally impervious to it’s effects. Unfortunately I know of no butyrate that can be sloshed in a tank and give 100% protection. The slightest crack in the sloshed covering can lead to separation of the sloshing compound inside your tanks... another real mess.
If you have a gascolator properly installed that is the best place to drain the tanks. Flight planning should leave you with a couple of gallons of fuel when you get back to the hangar.
