This has resulted in the same E10 in the gasoline tank for a long time (probably 2 years), The result - heavy rusting, failed pumps (one in the tank and one in the fuel line), clogged filters. So this is a clear example of one of the downsides to this E10, You need to keep turning it over, keep tanks full, etc. to stop any effect of the absorption of water from the air. My a/c has aluminum tanks, two in-line filters which I watch and change, and I check the carb bowls every 50 hours. Also never any vapor lock, up to 9500ft (I haven;t cruised higher) Peter CH701SP 912ULS 470hrs 1500TBO Trio EZ Pilot ________________________________ Message 2 _____________________________________ Time: 03:58:57 AM PST US From: "Tim White" Subject: Re: RotaxEngines-List: Re: Octane booster Hi, I'm new to this list, but know of two guys (snowbirds) on our airpark in Florida that drain their tanks and run a limited amount of 100LL through their 912s for summer storage (5-6 months). They claim 100LL will not deteriorate the fuel system as with the autofuel they normally use. Seems to work.

Do the same for mogas and it will start to degrade in 2 months. The key here is SEALED, i.e. no vents. Add venting and mogas starts to deteriorate in days. I've not tried Sta-bil for ethanol adulterated gas but the regular grade works great for non ethanol grade.

What I do during the down periods (spring, summer) is drain the tank after about a week and half or so. If it's going to be sitting longer than that I'll drain completely and refill with 100LL. I'll run the motor a bit to get the E10 out of the float bowls and lines also. I've found 100LL keeps a lot better when sitting that autogas. And I wouldn't like E10 to sit for any period of time at all due to moisture retention, etc. LS -------- LS Titan II SS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=277895#277895 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
