![]() wrote in message oups.com... So you wonder what's going to happen to general aviation because of the high prices of avgas? Acquire yourself an aircraft which will fly on auto fuel. I have a lovely 172G with autogas STC and will sell it to you for a reasonable price. Why fly a 172 when you shortly will be able to rum the big iron? There's a Lycoming TSIO-540 running in OK on avgas. http://www.engineteststand.com/testdata.htm http://www.taturbo.com/prismad.jpg |

Test stands are inadequate to simulate flight conditions. In the meantime only low-power, lower-compression engines are legal for mogas. Cylinder pressures, heat, and many other considerations in a TSIO-540 don't make it a good candidate for high-volatility mogas. I don't know of any injected or turbocharged aircraft engine which could safely run on mogas. We have big-engine aircraft like Pathfinders and Bonanzas on our field with vapor-lock all the time, and that's with the blue gas. |

Well, vapor lock has nothing to do with the type of fuel you're running. |

Answering Matt's statement that vapor lock has nothing to do with the
type of fuel: One reason why the FAA is reluctant to grant STC's for mogas is because of its vapor-lock propensities. There have been studies and plenty of discussion about the differences in vapor pressure at the same temperature and pressure between avgas and mogas. There was some discussion not long ago, iirc, in RAH. Google and you will find. |

Anyone worries about what the rising avgas price to the light plane ownership in the U.S? I have absolutely no doubt that the average avgas price will surpass $5/gallon in about 5 years. We'll probably see a significant drop of GA flying, along with a big drop of the value of used airplanes. It's really depressing just to think about it. I wouldn't worry about it too much. Most people don't realize some simple facts about oil and fuel costs. One, the price we pay per barrel has zero to do with its availability. The price we pay is basically a speculative futures price based on estimates of what the market will bare. Fact is, oil companies around the world are making record profits. Two, there is now more known oil in the world than there has ever been in the history of mankind. The only thing that changes is where it's at, how cost effective it is to obtain it, and what quality the oil is. With the prices as high as they are now, VAST supplies of oil suddenly become economically feasible. Three, as the price per barrel sits above $50/barrel, especially above $60/barrel, MANY, MANY, MANY alternative fuel options become economically feasible. Heck, if they would lift the ban on hemp (which is not pot) in the US, ethanol can actually become a viable fuel source without government support; as is the case for corn-ethanol production, which at best, is at a break even form an energy perspective. Meaning, it takes about as much energy to produce ethanol from corn as we get back out of it. As a rule of thumb, it actually takes more energy to make corn-based ethanol than we get out of it. Hemp is known to provide up to 3x better yeild, per year, than corn and requires no pesticides (unlike corn). Other alternatives include pure bio-fuels and even purely synthetic options. Synthetics are expensive but becomes feasible around $50+/barrel. So why don't we see fuel more options? Simple ecomonics. The oil companies don't want to invest the billions into processing more low cost crude ($28/barrel) because they want to be assured a return on their investment. If oil prices fall, it's harder to get that return on new refineries. Alternate fuel supplies take time to bring to market and the new entries require a stable market to justify the investment. In the global picture, war = unstable oil markets; which is where speculation comes in. If five years from now, prices have continued to rise, then I think you'll start to see MANY alternatives can start to come into the equation which will lower our fuel costs again. ...as theory goes anyways... ![]() Cheers, Greg |

Some would suggest profiteering by the oil companies but our Government watchdog can never find proof, as the Govt creams a fortune in taxes on the fuel sales. Brian |

You need to read up a bit on how oil trades on the world markets. I have some idea of how oil trades but there comes a time when the constant coincidence of the price rise occurring to coincide with large parts of the population going travelling by vehicle streatches beyond the realms of probability or 3 sigma if you prefer. The current diesel price, given it is cracked out early in the process, is even more laughable. Brian |
