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_mossmotors.com_ (mossmotors.com) . 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.

I wonder if you can help please. I have a half share in a M44-1200 - Rotax 912. G-BXWH based in the UK. We have aproblem with the airspeed indicator reading about 10 MPH low, and the Rate of Climb meter is reading low as well. I'm told we have the same arrangment that others have that works correctly. Any ideas where to look for a cure for both please?

I did the trick of putting a 10cm piece of sealed tube on the pitot and then carefully kinking it while watching the ASI. (Don't want to over speed it.) Once kinked, hold it in place with a rubber band or tie wrap and wait to see if the airspeed decays. If so you've got a leak in the pitot system. My leak was between the bezel and glass. Do the same with the static system, except start with a kinked hose and let it un-kink after sealing it to the static system. Once you've confirmed no leaks then question the location of the static port. My system ran 10mph low using the "same arrangement" as well so I just disconnected the static port and ran it at cabin pressure: much closer.
