You call me Clueless while Jay calls me a liar and misinformed. It seams that the two of you think that anyone who doesn't use MoGas is an idiot. I am not. I follow no crowd and mantra but my own. I did the research and simply came to the informed decision that it is too much trouble to do correctly and the benefits don't outweigh the risks. Others who my be contemplating the use of MoGas also deserve to hear both sides as well. I never said that the proper use of UNCONTAMINATED MoGas was unsafe. I did say that it is very hard to be sure you have uncontaminated MoGas (and getting harder every day with all this ethanol BS). You are lucky that you have a convenient supply of MoGas presumably from a reliable source. But you still are required by the STC you are using, to test each and every load of gas you pump into your plane. You are testing it, aren't you? I ABSOLUTELY DID SAY THAT THE USE OF UNTESTED MOGAS IS UNSAFE!!! (You or anyone else would have to be an absolute blithering idiot to disagree with that statement) Every piece of information I passed along was researched and verified. (would you like me to list the Lycomming Service Letters and Service Bulletins again?) Or perhaps you should just read the instructions that were added to your Flight Manual as part of your MoGas STC. You do have the STC, don't you? The complete answer to all of this, is a type of AvGas called 90/96 which is essentially 100LL without the lead. It would have all the quality control and positive features of AvGas without the problems caused by all that extra lead and could be in use tomorrow. But my guess is that MoGas advocates won't like it because it (undoubtedly) will be more expensive than MoGas. We can agree to disagree BUT DON'T CALL ME CLUELESS, MISINFORMED or a LIAR. One more time... If you do choose to fly on MoGas, you must have the STC that allows the use of MoGas. YOU MUST FOLLOW ALL OF THE PROCEDURES SPELLED OUT IN THE STC... Period, end of story... Fly SAFE (not cheep) PilotKris In a message dated 7/13/2006 6:49:22 AM Pacific Standard Time, AWatt@xxxxxxxxx writes: PilotKris Jay is absolutely correct in his postings and you, my friend, have "NO CLUE". It's sad that you choose to follow the "doom and gloom" mantra of the anti MoGas crowd. I too did much research BEFORE using MoGas and couldn't find a SINGLE incident of an accident being caused by MoGas use. I did find a few incidents of misfueling with water contaminated AvGas (hmmmm, maybe it's actually SAFER to carry my own fuel to the airport instead of trusting those leaking underground storage tanks on the ramp). As it stands, my local airport has a beautiful self service facility which dispenses alchohol free gas, pays all aviation fuel taxes, and sells it for a price similar to the road fuel. Face it, it's perfectly safe to fly with good quality, non-contaminated MoGas. Be my guest, keep burning 100LL but PLEASE STOP thinking that somehow you are safer while doing so.

The only one spreading those is you. You STILL seam to have a problem differentiating FACT from OPINION. I understand where you get your opinions. Your I.A.'s might even be considered "expert" but it's still just an opinion. I will reiterate the Facts. 1. The manufacture of the airplane (and it's fuel system) specifically PROHIBITS the use of anything but 80/87, 100LL or 100/130 AvGas. 2. The Manufacture of the engine specifically PROHIBITS the use of anything but 80/87, 100LL or 100/130 AvGas and goes so far as to say (in S.B. 398) that any engine that has run on any other "non-specficed" fuel is UNAIRWORTHY unless it has been torn down and inspected. They don't say that it's OK to use MoGas if you foul your plugs. They don't say it's OK to use MoGas if your Local A&P says it's OK. They don't say it's OK to use MoGas because you only fly 75 times a year and it "couldn't be that bad". THEY SAY DON'T DO IT... EVER! 3. The very people you quote as a "source", EAA and the STC holder state YOU MUST TEST ALL OF THE GAS YOU PUT IN YOUR PLANE EACH AND EVERY TIME YOU FUEL THE PLANE (specifically because ethanol will SERIOUSLY SCREW UP YOUR PLANE IF NOT YOUR LIFE). 4. You have know idea what is coming out of the pump at your local gas station (even uncontaminated gas may now be as much as 40% ethanol). 5. There are dozens of opportunities for the MoGas supply to get contaminated buy the time it gets to the local "HyVee". It's the nature of the MoGas distribution network and there is no way around it. THAT'S WHY YOU MUST TEST EACH AND EVERY LOAD OF MOGAS YOU PUT IN YOUR PLANE! Oh, as for your "Sources". FAA had never said MoGas is better than AvGas. They do say however if you use Mogas, YOU MUST FOLLOW THE PROCEDURES OF THE STC TO THE LETTER. That means testing each and every load of MoGas you put in your plane (and you aren't). The EAA is the EXPERIMENTAL Aircraft Association (which I am a member). The PA28-235 is not experimental. As such, must be operated in accordance with the manufactures (both airframe and engine) operating instructions. Even so, the work of the EAA led to the MoGas STC and they say (are you getting tired of me saying this yet?) YOU MUST FOLLOW THE PROCEDURES OF THE STC WHICH INCLUDES TESTING EACH AND EVERY LOAD OF GAS YOU PUT IN THE PLANE! The AAA? While they're not exactly spring chickens, the 235's aren't Antiques and I've never heard of a O-540-C4B5 being referred to has an "antique" either. As such, I don't think that even counts as an expert opinion. Your I.A.? His (possibly "expert") opinions don't count as facts. Frankly Jay, I'm worried about you. You have a very cavalier attitude about your safety and the safety of your passengers. It's clear from your posts that you aren't testing your MoGas for ethanol. THAT CAN GET YOU KILLED. The PA28-235 is especially susceptible to alcohol/ethanol contamination because it will turn the fiberglass in the tip tanks to goo. Goo that can clog up the fuel lines and that my friend means engine failure. Clearly you have issues with the establishment. My suggestion for you is to put an "EXPERIMENTAL" sticker on your plane and that way you can run whatever fuel, whatever strobe, whatever engine you want unfettered by the restrictions placed on you by THE MAN 'cause you obviously (think you) know better. For the others reading this, KNOW ALL THE FACTS and make your own decisions. But for goodness sake, if you do decide to use MoGas, FOLLOW ALL OF THE REQUIREMENTS OF THE STC! Fly Safe! In a message dated 7/12/2006 6:37:19 AM Pacific Standard Time, jjhoneck@xxxxxxxxx writes: Well, Kris, I'm sorry if you took my response as a personal attack. You clearly don't spend much in the on-line community of pilots if you perceived my response as in any way insulting. Perhaps I've become too thick-skinned, but my response would be called "timid" in some of the aviation forums I frequent. Suffice it to say I apologize -- I didn't mean any affront. That said, I think your preception of mogas, and mogas users is wrong. Here's why: 1. If there were two pumps at my airport, and they were the SAME PRICE, one avgas, one mogas -- I would put the unleaded mogas in my plane. It is simply a superior fuel for our low-compression engines. 2. You are the one who is running a fuel -- 100LL -- that was not recommended for our engines. Mogas has been SPECIFICALLY approved for operation in our engine. 3. The ethanol issue is a problem, but one that can be managed. From all the research I've done, the worst thing that can happen is that it can harm the fiberglass in our tip tanks -- IF you let it sit in there for long periods of time. Since we fly around 75 times per year, even if I accidentally got some ethanol, it wouldn't be in contact with anything for very long. (On a slightly different point, if we, as voters, allow our government to mandate the use of ethanol in all gasolines, we will have driven the final nail in the coffin of general aviation. Flying has dropped to all-time low levels, as fuel costs have tripled, and many owners are only able to fly as often as they do because of the mogas STC.) 4. You seem to be dismissing over 15 years of experience burning car gas in our plane as irrelevant. You are also dismissing hundreds of thousands of trouble-free hours of operations, by pilots all over the world, as meaningless. Does this make sense? 5. If your A&P won't work on a plane because the pilot uses car gas, he's ignorant of the facts. My A&P/IA (an EAA and AAA grand champion builder with over 40 years behind a wrench) has personally rebuilt over 100 Lycoming O-540s -- including mine. He will tell you that the very cleanest engines are the ones that burn UNleaded fuel, since it is the overload of lead that causes so much gunk to build up inside our engines. I can put you in touch with him, if you'd like? 6. Fouling spark plugs IS caused by improper engine management -- if you believe that it is somehow "normal" to severely lean your engine in order to make it run "properly". How in the world did we ever come to the point where we consider it "normal" to burn a fuel in our engines that requires such bizarre and archaic operation? Here's the bottom line: By using 100LL, YOU ARE BURNING A FUEL THAT CONTAINS 400% MORE LEAD THAN YOUR ENGINE WAS DESIGNED TO USE. The ONLY reason you have to lean so severely is to prevent the bottom plugs from loading up with little BBs of lead that can't be scavenged by our low-compression engines. Imagine if automobile owners were sold a fuel such as this! Let's say, for a moment, that your local gas station started selling a fuel like 100LL. Everyone was told that it was a fine fuel -- maybe even BETTER -- for full-power operations, but every time you coasted, or idled at a stoplight, you would have to pull this little lever back on the dashboard, or your engine would eventually stall. How much of THAT fuel would they sell? If, despite these facts, you still consider 100LL to be a "proper" and "normal" fuel to use in your plane, well, I don't know what else can be said. 7. The Lycoming disclaimer of mogas is an insurance ploy, plain and simple. It gives them an out on paying bogus claims, and is no different than all the other fine print insurance companies have packed into their policies. Remember, we're not talking about stuff you're distilling in your bath tub -- we're talking about a fuel that has been *specifically* approved by the Federal Aviation Administration -- a group that is not generally considered to be run by a bunch of crazy, slip-shod, laid back guys. Let me give you an example of how the FAA works. In 1999, the FAA ORDERED me to remove a perfectly fine set of Aeroflash strobes from my old 1975 Warrior, because we discovered that they were STC'd for a PA28-140, not for a PA28-151. It didn't matter to them one whit that those strobes had been on the plane for over 26 years -- they HAD to go. It didn't even matter that they worked -- they were clearly a "hazard to flight" -- and I had to spend $1000 removing them, and reinstalling a set of virtually identical Whelen strobes that had the right paperwork. No amount of pleading, cajoling, or begging saved me from that fate. Now, does this REALLY sound like the kind of organization that would casually approve a fuel for use in your airplane? Given their intense level of scrutiny, do you REALLY think they would allow car gas in aircraft if there was ANY chance of failure? 8. Transporting fuel IS a pain in the butt, but only because so few airports actually sell mogas on the field. (There are two within 20 miles of Iowa City -- but the FBO at Iowa City refuses to follow suit.) I (and thousands of people just like me) have solved that problem by installing a professionally-made fuel transfer tank, complete with metered pump and filter, in the back of a pick up truck. It's safe, works great, and also allows me to have fuel for my lawn mowers, weed wackers, blowers, etc., whenever and wherever I need it. It's a wonderful thing to have around. My sources for this include: - The FAA - EAA (Experimental Aircraft Association) - AAA (Antique Aircraft Association) - Iowa City Aircraft Repair (Keith Roof, A&P/IA) Again, I say this: If you want to use avgas in your plane, have at it -- but please don't spread rumors and old wive's tales about using mogas. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" -------------- Original message from PilotKris@xxxxxxx: -------------- Well Jay... Since you seam to feel the need to attack me personally (one of the reasons I almost never post what might be useful information to others), let me respond your attacks. It is clear you didn't even bother to read thoroughly my post. I never said that AvGas was "better quality" than MoGas. What I said was there is an FAA mandated, dedicated supply chain that provides the AvGas that is pumped at the airports. Quality control exists all points. That doesn't mean it's "higher quality" but it does provide assurance that you are getting what you think you're getting. No such QC exists at your local "HyVee". What happens if the guy filling the tanks (at the refinery, at the distribution depot, the driver of the delivery truck, at the station, etc.) accidentally dumps a few hundred gallons of diesel, or ethanol, or whatever into the fuel that ended up in your tank? It's VERY easy to do. Even if the station knew of the mix-up, do you think they will dispose of the gas (huge HAZMAT issues and expense) or would they just keep pumping knowing that it "probably won't hurt anything" (and it probably won't hurt...A CAR). The information I brought to the attention of the group for their consideration so that they can be informed of all the issues concerning the use of MoGas. Not just the one-sided opinions of some. I only provided FACTS not opinions in my post.(except for the part about MoGas smelling bad, that was my opinion). You sir, only provided your (obviously biased) opinions. Let me reiterate a few of the FACTS and add more FACTS. 1. If you are going to use MoGas per a STC, YOU MUST FOLLOW ALL OF THE PROCEDURES IN THE STC (every MoGas STC I have seen requires that every drop of fuel you put in your plane be tested for alcohol). The purchase of a piece of paper and a couple of stickers is just the beginning. 2. The differences between MoGas and AvGas go far beyond the octane rating and lead content. 3. The company that designed and built the O-540-B4B5, Lycomming, DOES NOT APPROVE OF THE USE OF ANY FUEL OTHER THAN 80/87, 100LL, 100/130 AVGAS... PERIOD. They go so far as to say the use of any "unspecified fuel" (and MoGas from the HyVee certainly counts as unspecified) requires inspection of the engine by "competent maintenance personnel" (read teardown). 4. If you are going to transport fuel, you must follow all of the requirements of your local fire department including using proper containers and procedures. Those are the FACTS not opinions or personal experiences. I actually did the research prior to forming my opinion. My sources included: FAA My local BP distributor My local fire department Textron Lycomming (read Service Letter L185B and Service Bulletin 398) Piper Now my opinions and observations: I feel that the plug fouling issues to be combinations of poor operation of the engine(s) and poor maintenance. In almost 3,000 of flying, I've only had one lead-fouled plug and that was my own fault (too long between cleanings). No A&P or I.A. I consider competent enough to work on my plane would even think of suggesting an owner/operator use MoGas. My I.A. had gone so far as to say he won't work on a plane that uses MoGas (he thinks it stinks too). I feel that most people using MoGas are thinking with there wallets, not their heads. They also tend to rationalize the use of MoGas by claiming it's somehow "better" than AvGas. While there might be some people out there who are doing it correctly, I've never seen a pilot who follows all the MoGas STC procedures and I've seen many pilots do things that are down right dangerous like transport fuel in the trunk of their car in used paint thinner cans. I WILL NOT USE MOGAS IN MY PLANE NOR WILL I FLY/INSTRUCT IN A PLANE THAT HAS USED MOGAS. I won't expose my family to the potential risks it brings to save a few bucks. Besides, how egotistical would I be to think I know better than the people who designed and built the motor?... But I'm just a 3,000 hour CSEL. CMEL, CFI, MEI. What do I know...
