This makes me suspicious that my MOGAS contains alcohol, so from now on I intend to be more scrupulous about 'bottle testing' my fuel sources. The other issue with MOGAS relates to winter inactivity. Car gas should not be stored for more than three months. In the past the aviation practice for fuel tanks was to leave them full to prevent/ reduce condensation inside the tanks. But now I'm wondering if that works with MOGAS over the quiet winter months. Does the stabilizer sold in auto stores do the job adequately? Or should I keep the fuel tanks mainly empty over the winter, just adding enough fuel each time I go flying? What are the active pilots on the list, who use MOGAS, doing with all this?

Apparently if you do this with good 93 octane gas the octane rating isn't effected either. Apparently the phase separation is more visible if the water had a particular color to it to begin with. Probably works well too. No different than draining the gascolator of water. Once the water is out the gasoline it's fine, you're just removing the dregs, and in this case the dregs are the water as well as the saturated ethanol and what you're left with is ethanol free gas. http://www.c-bstatesman.com/news/2008/0904/Front_Page/001.html http://wecleantanks.com/news/003-phase_separation_and_water_in_ethanol.php http://en.wikipedia.org/wiki/Ethanol_fuel http://www.sunworld.net.au/startron/Wc35c468eb2769.htm -------- Andy Shontz do not archive CH601XL - Corvair www.mykitlog.com/ashontz Read this topic online here: http://forums.matronics.com/viewtopic.php?p 2590#202590 ________________________________ Message 13 ____________________________________ Time: 12:13:01 PM PST US From: "Dave Austin" Subject: Re: Zenith-List: Ethanol issues Grant, My experience with the Zodiac is that in December I fill the tank with Shell super and put in 1 1/2 times the recommended gas treatment and then run the engine (912) for five minutes to get the treatment to the carbs.

Mine are already sealed in my wings, under a generous layer of pro-seal (the black goo of death, as somebody called it). I heard (at the builders dinner at Oshkosh) that there was a problem with the seals under the gas caps of the fuel tanks. Might ought to replace those with something made of a different material.

I only keep 3 to 5 gallons in each wing tank and 4 to 5 gallons in the header. I dont refuel until just before the next flight. When a can of fuel has set for more than a couple of months, I pour it into the car and refill the can with new 87-octane. This seems to keep the fuel fresh and gas handling safe. I do use a 16-gage wire with gator clips each end to minimize static build-up between tank and can at filling. I also place a small edge-bound rubber-backed rug with a centered 2-1/2-inch hole over the filler hole to avoid drips and splatter on the paint. I sometimes forget to pre-release pressure on the spring-cap just before filling. This seems to take care of the long inactive periods in winter. I dont use stabilizers, but prefer the addition of fresh fuel just before flight, easiest done if left in the can until you need it. On a side note, our airport managers recently got fussy about our having fuel cans in the hangars and it was successfully argued that several tanks to the volume of the aircraft were necessary to drain and check fuel tank strainers and provide safe fuel containment in the event of a leak. Just be sure you use OSHA approved containers that are stable for transport. Steel 5-gallon drum types are ideal and 50 gallons is the max allowable for each of our hangars. Now that Homeland Security has decided to search our cars for explosives before we drive thru the coded gate, never mind the gasoline, apparently, you do have to have the right container to get it there. I periodically check my VDO float gasket and fittings for ethanol damage and do replace the short hose and paper-type plastic filter annually.

Well we have had a major accomplishment. Our 601 HDS is on the gear and I got to set in it for the first time and make airplane noises. However, when I put my feet on the pedals they contact the arch of my foot and the ball of my big toe hits the toe brake bar . When I push the pedal in a natural motion to move the rudder, the brake is depressed. My heal rests on the floor, between the rudder pedal and the crossing stiffening member. Is this the normal set up? We don=C3=A2=82=AC=84=A2t have the seat cushions in yet, so that will elevate the pilot forward and up some, but I don=C3=A2=82=AC=84=A2t think the geometry of the knee will change much. I am five eleven (on a good day) and my partner is over six feet. The general feel is much bigger than I thought it would be. It seems much roomier than a 150 and the nose is much higher when you sit in it without cushions. We could easily adjust the rudders pedals now, much harder later. My question is, does this observation mean we have an issue or am I missing something.

That's not messy at all. And while you are correct that ethanol laced gas has less power and efficiency it does increase octane and when you take it out of gas the fuels octane is at best questionable. Not to worry though I'm sure we will read all about it in an in-depth accident investigation at some point. ashontz wrote: > http://www.fuel-testers.com/instructions_alcohol_fuel_test_kit.html > > Check the test kit.

Sounds like a 93 mo-gas with the ethanol removed for a STC'd plane meets that requirement. Plus, it's considerably cheaper.

If so, then you've done this exact process already hundreds of times except you didn't add the water. That gas that's on top of the water is perfectly fine, that's why you feel safe going flying AFTER you've removed the water from the bottom of the tanks and from the gascolator. The ethanol is a water sponge. It sponges up all the water you added and then the sponge falls to the bottom of the tank for easy removal, the excess water also falls to the bottom of the tank, for easy removal as well, just like before your pre-flight.

The process for ethanol removal is the same as the test kit. Apparently 10cc of water is enough to dissolve all of the ethanol out of 20cc of E10. I'm sure this is the method the guy at our local chapter was using to remove ethanol from gas.

But comparing draining water out of the tanks to adding water too remove ethanol is without a doubt the silliest thing I have ever seen you post. When I drain the sumps I'm not reducing the octane of the fuel. Also, if it ever takes me more than 2 or 3 testers full of fuel to get all the water out of a tank I'm having all the fuel drained and start from scratch. I've had to do that twice since I started flying and I was there when my Grandfather had them drain all the fuel out of a LearJet because of it. -------- W.R.

Unfortunately, I seriously doubt that the gasoline will meet its stated octane rating without the alcohol. Higher octane gasoline is more expensive, so the oil companies will probably produce the lowest octane gas they can and bring it up to its stated rating by adding the alcohol. If your engine can run on regular gas and you use this method to remove alcohol from premium gas, you might get away with it. For me, if I can't find alcohol free auto gas, I will use 100LL avgas. Since the state of Michigan mandated on January 1st this year that all auto gasoline sold here must be contaminated with at least 10% alcohol, I've been burning nothing but avgas in my plane.

And that's how the test kit is determining the amount of ethanol in the E10, by forcing it out of solution and then comparing the the level vs what the deliniation line SHOULD be between the 10cc of water and the 20 cc of pure fuel. With pure fuel, that deliniation line would be at 10cc. If there's 10% ethanol (E10) then the line would show up at 12cc. Correct? How's that silly? That's how the test kit works. You drain water out of the gascolator. Correct. and the water lays at the bottom of the tank so you can drain it, correct? So what's the difference between that and adding water to fuel, letting it settle and in the process soak the ethanol out of solution and then draining all that crap out? That's something your wife does every Thanksgiving when she takes the turkey drippings, lets them sit and then takes the baster and skins the fat off the top, except in reverse.

It would indeed work. I knw what you're saying about the octane rating, but in one of those links it stated that certain high octane rated gasolines had their octane before the contaminant (ethanol) was added and hence would not effect the octane rating after separation. bryanmmartin wrote: > Actually it only takes about 0.5% water to cause phase separation of > E10, so for 24 gallons of E10 you would need just about a pint of > water.

If 100ll is available, that'll be my first choice. But what if it isn't available? I'd like to have the flexibility to use auto gas (that might or might not have ethanol in it) if I need to. We don't know what the fuel availability will be a few years from now. We should build our fuel systems today for what we might encounter in the future. - Pat -------- Patrick 601XL/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p 2663#202663 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith-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/zenith-list Browse Digests http://www.matronics.com/digest/zenith-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.
