There was one stupid pilot trick where he took off with an engine that wasn't running properly, and others that said they couldn't explain the power loss. One accident was a certificated airplane, maintained by the owner/pilot (not an A&P). What stupid pilot trick did he do? I dunno. They didn't say what the CAUSE was. And carb ice doesn't usually (almost never???) come from water in the fuel, but from water in the atmosphere. Water and fuel system corrosion are a natural hazard of having your plane tied down on the ramp, but that never shows up in an NTSB report. I don't have the time to cull through thousands of accident reports (although my home page is the NTSB accident/month page), and I see far more stupid pilot tricks than I see accidents that occurred when using auto fuel. I thank you for the list though, because I didn't know that there were that many accidents where auto fuel was used. But again, none of the reports that I read said auto fuel CAUSED the accident. There was the inference that it MIGHT have contributed to the accident though. Linn do not archive gmcjetpilot@yahoo.com wrote: > Well you thought wrong.

I understand adding the "local content" for season and geography in the auto fuel side but I am under the impression that 100LL is the same everywhere. Is 100LL blended at the tank farms and then delivered locally, in which case the transportation/distribution costs would be slightly higher or does it come from one main refinery and then get trucked across the country in which case the difference in price might be very recognizable? Also wondered if 100LL and Jet goes through the normal pipeline distribution system or is it land-hauled because of the extremely low volumes compared to auto fuel? We appear to have a pretty amazing system for auto fuel distribution but I am wondering if there is a drastically different distribution cost to av fuel? Thanks Bill S 7a Ark -----Original Message----- [mailto:owner-rv-list-server@matronics.com] On Behalf Of Pete Cowper Sent: Saturday, July 08, 2006 2:36 PM --> RV-List message posted by: pcowper@webtv.net (Pete Cowper) The seasonal blending and geographical blending by automotive gasoline refiners does have a significant effect on the operation of the engines. When I was Terminal Superintendent of the Union 76 tank farms at San Diego and Imperial (El Centro) Terminals back in the early 1980's, we used to back haul the Imperial "desert gasoline" for the coastal San Diego's California Highway Patrol during certain seasons of the year for fuelling the 24/7 patrolcars that ran severe duty periods of idling and high speed pursuits. As engines used in aircraft adopt modern automotive computers utilizing such monitors as temperature probes and O2 sensors, the engines will be able to finely tune themselves as they encounter differing weather and altitudes. With the 1930's technology of many of our Lycoming & Continental aircraft engines, this thread has been informative with its cautions and could prevent damage from unexpected power off landings or even save some lives. If a plane is based on a private strip at a rural home, farm or ranch where automotive gasoline for vehicles and equipment can be delivered by commercial tankwagon, the savings can be measurable if the automotive fuel is found to be adequate for the aircraft engine. Our local fairly busy airport, with commercial airline service on its 6,559 foot runway with ILS, only pumps 150,000 gallons of Aviation gasoline a year. If this were a corner filling station pumping only 150,000 gallons in just a month - it would be facing closure for being uneconomical. Refiners are making aviation gasoline more as a service than a profit center. We need to continue to educate ourselves about alternate fuels as aviation gasoline will no doubt have to change from the currently available 100LL to a fuel that has other shared applications to make it at least marginally profitable to produce and distribute. As to the flamers and naysayers . . . "Don't confuse me with the facts, I've already made up my mind."

RV planes aren't gas guzzlers! At 8000 ft on an economy cruise setting you get over 24 mpg (assuming no head wind) I would say that's pretty good. Fly at 10,000ft or 11,000ft and you get even better millage. That's better than I get in my Ford Ranger. It's only about 6 mpg away from what some call a high millage for cars. My 24 mpg figure was based on the range listed on Van's website for an RV-7 at 55% power with the 160 hp engine. do not archive. Chris W KE5GIX Good data point, I hadn't read that on Van's site. I typically fly higher than 8000 feet, and since I've always been an efficiency freak, my engine monitor has a readout directly in MPG (based on TAS and fuel flow). I spend a lot of time tweaking & tuning to eke out that last possible .1 mpg on those long cross countries. At 15,500 I can do a little better than 30 MPG at 175 mph TAS. Anyone else into fuel efficiency? I'd love to hear your numbers. I honestly don't know how the rotary engine compares to a Lyc when flown for max efficiency. But I suspect it isn't much different. While I have always been into energy efficiency, I have grown weary of the painfully stupid mass media debate on the subject. Many of the same folks who demand better fuel economy standards are often the same ones to decry small cars as dangerous. Now I intend to use all the fuel I want while dreading the day someone decides that private aviation is too much of a security risk.

For as many hits as you found with the words auto fuel I could if I had the time find many more example of the same types of accidents with aircraft using strictly avgas. I am sure you as I do as a flight instructor read the accident reports everyday. The only situation where I agree with you is in the handling process where fuel can become contaminated with water or crud. Jerry do not archive ________________________________ Message 7 _____________________________________ Time: 10:12:18 AM PST US From: Jerry2DT@aol.com Subject: RV-List: Re:Fuel economy / was Fossil energy fuel..... Tracy, With due respect, Van's tested two more or less identical rotary conversions in the "RV-Ator, 2nd issue of 2005. These were both RV-8's built as "twins" by two friends and retired pilots, Jim Clark and Gerry Gustafson. These were Powersport Rotaries and turned out beautifully. I had the pleasure of viewing them and talking to both men at Van's Homecoming 2004. The article is quite extensive, as was the testing, but I'll just mention that at cruise with identical speeds, the article states "But, in all cases, even at equal speeds, they burned more fuel than the reciprocation engines." Also... "The rotaries were definitely noiser inside and out." For instance, at cruise Van's RV8 burned 5.05 gals and the two rotaries 7.65 and 7.1 respectively. This was a round trip of 140nm. So it appears from their data that rotaries, at least these two, burn substantially more fuel. What do you think? I don't have a scanner, but would be happy to fax or mail copies. Jerry Cochran Wilsonville, OR That was seriously Cool data Dan. Thanks also to Ed Bundy who supplied his numbers. It is surprisingly hard to find RV drivers who keep track of this stuff (too busy having fun in these things which I also understand : ) be a significant advantage. If you ever get the chance Dan, I'd like to see you do the same test but instead of dropping manifold pressure only, try dropping the prop rpm to get the same fuel flow numbers you used. This should reduce pumping losses and result in even better numbers. "Do not operate" zones on the prop rpm is the only possible problem I can think of. I don't have that problem with my fixed pitch wood prop but I have to put up with very high pumping losses, especially at low altitude (which is another reason I cruise high). Bottom line is that based on this info, I don't see a nickel's worth of difference between the Lyc (when run LOP) and my Mazda rotary when it comes to fuel economy. Cleanliness of the airframe makes more difference than the engine. I always burn less fuel than the guys who run Lycs ROP. The horror stories about the fuel consumption of the rotary are based on automotive experience. Ironically, the rotary is at it's worst in auto use. The lower the engine load, the worse the rotary is. Car's typically run at 10% or less power settings. At low power settings the flame goes out in the large quench areas of the rotary combustion chamber resulting in more unburned mixture. The higher the power load is, the longer the flame stays lit and more complete combustion results. The crumby results on the rotary RV-8 comparisons they did at Van's home drome were the results of two factors. 1. The fixed prop RPM rule put the rotaries at a disadvantage. They should have allowed the pilots to set it at best economy for the two engine types (it is not the same). 2. The EFI controllers used with the Powersport engines do not allow the pilot to optimize the mixture. They were essentially running at full rich the whole time. The designers of it did not consider the users capable of deciding this and programmed what they thought was the safest mixture setting (rich).

The Sahara was farm country a few thousand years ago and turned desert way before the machine age, and even before the human population explosion occurred. What about the redwood cones found above the arctic circle? I don't say emissions of various kinds have NO effect, but how can the events (volcanic and otherwise) that produce far more CO2 than decades of man made emissions be discounted? I'm curious also how we can presume to know the average temperature of a point on the earth's surface when records have been kept for only a hundred years or so. Is it the same kind of science that can build a complete culture from a couple of knife points and a molar? No offense, but it seems the science that's out there is pretty selectively chosen by the supporters of the current global warming theory. There's lots that point the other way, too. The people pushing the global warming theory aren't exactly operating out of the back of a VW bus, either. There's plenty of money on both sides and people on both sides making a living advocating their particular position. ----- Original Message ----- Sent: Sunday, July 09, 2006 1:00 PM > --> RV-List message posted by: Mickey Coggins > > Vincent Osburn wrote: >> With no disrespect intended to anyone.... man made global warming is a >> farce I believe..... > > There were a lot of naysayers in the 60s and 70s about the effects > of smoking, too. > > Just look at the money behind the people that say that global > warming is not real.

The fuel economy test was based on a side by side cross country trip where the prop rpm was to be held at a certain rpm (2500 as I recall) and the speed held at various airspeeds by throttle position. This test was reported in two places, the RVator and in Sport Aviation (or was it Kitplanes, memory slipping) and I can't remember which one reported the specifics of the test conditions. I'll see if I can dig up the article in my stacks of stuff for attribution.

Hi Jerry, I've read the articles (those were the planes I was referring to) and do not dispute the results at all, as I said, the rotaries had 'crumby' results. I only offered the reasons why I believe these two rotary powered planes did so poorly on the tests. My RV-4 is not nearly as clean (aerodynamically due to fit and finish) as those beautiful RV-8s but I get significantly better fuel economy when I try to duplicate those test conditions. I don't have a CS prop so can't do it perfectly. The main difference is, I have full control of mixture and they do not. As far as the noise issue, both of the RV-8s now have an improved muffler system since that test was done and are much quieter. Ask Jim & Gerry about that for details. Tracy Crook ----- Original Message ----- From: Jerry2DT@aol.com To: rv-list@matronics.com Sent: Sunday, July 09, 2006 1:06 PM Subject: RV-List: Re:Fuel economy / was Fossil energy fuel..... Tracy, With due respect, Van's tested two more or less identical rotary conversions in the "RV-Ator, 2nd issue of 2005. These were both RV-8's built as "twins" by two friends and retired pilots, Jim Clark and Gerry Gustafson. These were Powersport Rotaries and turned out beautifully. I had the pleasure of viewing them and talking to both men at Van's Homecoming 2004. The article is quite extensive, as was the testing, but I'll just mention that at cruise with identical speeds, the article states "But, in all cases, even at equal speeds, they burned more fuel than the reciprocation engines." Also... "The rotaries were definitely noiser inside and out." For instance, at cruise Van's RV8 burned 5.05 gals and the two rotaries 7.65 and 7.1 respectively. This was a round trip of 140nm. So it appears from their data that rotaries, at least these two, burn substantially more fuel. What do you think? I don't have a scanner, but would be happy to fax or mail copies. Jerry Cochran Wilsonville, OR From: "Tracy Crook" Subject: Re: RV-List:Fuel economy / was Fossil energy fuel..... That was seriously Cool data Dan. Thanks also to Ed Bundy who supplied his numbers. It is surprisingly hard to find RV drivers who keep track of this stuff (too busy having fun in these things which I also understand : ) be a significant advantage. If you ever get the chance Dan, I'd like to see you do the same test but instead of dropping manifold pressure only, try dropping the prop rpm to get the same fuel flow numbers you used. This should reduce pumping losses and result in even better numbers. "Do not operate" zones on the prop rpm is the only possible problem I can think of. I don't have that problem with my fixed pitch wood prop but I have to put up with very high pumping losses, especially at low altitude (which is another reason I cruise high). Bottom line is that based on this info, I don't see a nickel's worth of difference between the Lyc (when run LOP) and my Mazda rotary when it comes to fuel economy. Cleanliness of the airframe makes more difference than the engine. I always burn less fuel than the guys who run Lycs ROP. The horror stories about the fuel consumption of the rotary are based on automotive experience. Ironically, the rotary is at it's worst in auto use. The lower the engine load, the worse the rotary is. Car's typically run at 10% or less power settings. At low power settings the flame goes out in the large quench areas of the rotary combustion chamber resulting in more unburned mixture. The higher the power load is, the longer the flame stays lit and more complete combustion results. The crumby results on the rotary RV-8 comparisons they did at Van's home drome were the results of two factors. 1. The fixed prop RPM rule put the rotaries at a disadvantage. They should have allowed the pilots to set it at best economy for the two engine types (it is not the same). 2. The EFI controllers used with the Powersport engines do not allow the pilot to optimize the mixture. They were essentially running at full rich the whole time. The designers of it did not consider the users capable of deciding this and programmed what they thought was the safest mixture setting (rich).

I have mine based on what I've read and have actually experienced in the 2000 hours I've flown with auto fuel. If any of you want to continue supporting his narrative, be my guest. If you want to constructively discuss the use of auto gas in your airplane, I'll answer any questions I can offline. I'm no expert, and have never claimed to be; but, I do have experience with its use in my airplanes. I've found that experience to be a great teacher. That works for me and may not for others. If not, follow George's lead and stay far away from the auto gas pumps. Be safe with whatever you do.

I know by using your expert advice and procedures you can avoid ALL the above? Well may be not all. The ones that concern me the most are unexplained power loss on hot days. (hint hint, over, do you copy, vapor lock, Roger?) Note: Jim's mission in life is to promote auto fuel. He is doing a great job. When anyone talks about risk it means nothing, because it's not their fleshy buttock in the seat. I don't CARE. Just be informed. IF YOU USE AUTO FUEL AND SELF FUEL, aka HANDLE FUEL, PLEASE BE CAREFUL. THERE ARE RISK AND IT IS NOT ALL SUNSHINE AND BUTTERFLY'S. It may not be as bad as I make it sound, but it is not as great and carefree ( in my not so expert opinion) as Jim makes it sound. To use 1/2 auto and 1/2 avgas in each tank sounds weird to me. Don't you trust your fuel? What do you all think. If you don't trust you fuel to fly on, for all operations, do you want it in your plane? ME? not so much. YOU? decide for yourself. I don't care; I just suggest you know what you're getting. If you do use AUTO FUEL contact Jim. He knows way more than I do. However I know enough in 12,000 hours of flying to know how to stay out of trouble. I want to be an expert in power off emergency landings, but I never want to have to prove I am an expert for real. I want to always have a choice when and where I land. Using Avgas is just that little bit better in my humble but ever so right opinion. :-) It is NOT all about money as Jim makes it sounds. What does and off field landing cost? I hope only bent metal. Safety first, economy second. Boy I hope you have learned I have spoken and there is nothing left to be said. ha ha ha ha. Just kidding. Good debate, learned a lot, but lets keep it to facts and opinion and not personal comments. Have a NICE DAY.

Subject: Re: RV-List: The TRUTH about MOGAS (very long) Here's one for the "you're gonna die because you use autogas" folks: Today's OAT: 87 deg F. This morning filled up with three six-gallon jugs of 87 octane gas (not 93, not 91, but 87 octane), pulled the airplane up to the gas pump on our airpark and added 6 gallons of 100LL. 75/25 mix. Flew to a flyin, ate lunch then did a balloon pop contest and a spot landing contest. Had a passenger with me. Flew around the flyin for about an hour, in the pattern mixed in with several spam cans, super cubs, a T-6, PT-19, all in the pattern at 100-120mph (didn't win the spot landing contest but got two out of three balloons for a tie for first place). After we did that climbed out to 6500 and headed home, and had some fun with some cumulus. Hottest CHT hit 400 on the climb to 6500. After leveling off it settled back down to 365. Oil temp was 202. In other words, some ideal conditions for vapor lock. I'm here to tell you that I survived yet another hot but fun day using autogas, with not even a hint vapor lock and no signs of overheating.

The plane is an RV-6A, O-360 carbureted, one Lightspeed ignition some drag from old wheelpants and one crooked main gear fairing. Car is a 2001 Jeep Grand Cherokee Laredo, cruise control, 8 Cylinder and automatic with full time 4WD. Flight to Page took three hours (headwind) at 16,500 feet. Distance about 400 statute miles using 19.5 gallons of 100LL. The comes to 20.5 miles/gallon (6.5 GPH). Add one hour for additional time before and after the flight and the trip took four hours. As an aside, the trip back took 2.5 hours and burned 14.9 gallons for 26.8 MPG (6 gallons/hr). The trip back was at 17,500 feet and I had about a 30 knot tailwind. The car trip took 12 hours each way. 600 miles at 21 MPG burned about 28.6 gallons each way. The plane trip was done in one day whereas the car trip took over two days and required two nights in a hotel. Pictures for perusal included.

Well it made a big mess and did not work well. I asked a fellow RV builder (thanks Larry) about how he did it and found out from him that I could make a small pump sprayer into a pressurized brake bleeder. Here is how I made mine and it works great. It does take two people to do the job. I bought a 1-1/2 quart pump sprayer from Lowes allow with three different size pieces of tubing I put the tubing together and zip tied them to help hold them together. I used a small plug that came out of an instrument to attach another short piece of tubing to use as an overflow line to hold on the reservoir so the extra brake fluid could be caught in a bottle. Now this is the to do this job! When the job is all done the tubing can be stored in the tank to keep from losing it. -- My new email address: bobbyhester@charter.net Surfing the Web from Hopkinsville, KY Visit my web site at: http://www.geocities.com/hester-hoptown/RVSite/ RV7A N857BH SB wings-QB Fuse-XPO360 engine :-) ________________________________ Message 31 ____________________________________ Time: 08:14:37 PM PST US From: "JAMES BOWEN" Subject: Re: RV-List: Dinosaur Dung /...
