New fuel for GA?

No timing or mixture changes, no hardware changes? If it really is a substitute for 100LL, then that would be exactly what one would do. A pretty big 'if', though. If he can really make the stuff, why is he talking instead of mixing? If you can put avgas out at 1/2 the price as he seemed to be claiming, he could get a lot of attention with a pump pumping for $2.499 / gallon. Of course, if he makes the stuff without lead, then I don't see why it wouldn't work in most cars as well. At $2.499 / gallon, he could sell all he could make. *IF* he can do it. Based on the claims, the only unknown for auto use would be the oxygenate requirement, i.e. would alcohol have to be added and would it be compatible. As for sales, if he could really make the stuff significantly cheaper, why isn't he doing it now? The US isn't the only market for fuel in the world. -- Jim Pennino Remove .spam.sux to reply. |

No timing or mixture changes, no hardware changes? Timing? probably, if the octane rating is there. Mixture? You would probably have to adjust mixture accordingly. The different fuel density would probably require adjustments to float levels. Other hardware changes? I would have to see the materials compatibility tests before I started using it. It has been known since the 1950s that the synthetic rubber used in hoses, etc. can tolerate either petroleum-based or parrafin-based fuels. The problems arise when switching (either way) between the two, since each type fuel has its own effect on the polymers. Well, my luscombe had virtually nothing in the fuel system vunerable to anything this side of Skydrol, but only because I installed a metal float and an automotive fuel line. The float seat is metal of course and there's nothing else in the system that anythign can melt. My KCAB is anouther thing altogether. The LeBlond I'm going to have to check, but I think it has a standard MS carb form the thirties anyway, so it should be fine. What about the flexible hose from the gascolator to the carburetor? I would not use a hard metal line because of engine vibration and flexing. It is the synthetic materials use in hoses that is mentioned in my reference. If you can find one (I found mine by accident) a good reference is: "Aviation Fuels and Their Effects on Engine Performance," NAVAIR-06-5-501 USAF T.O. No. 06-5-4, prepared by Ethyl Corp supplied to U.S. Air Forces on Purchase Order AF-33(600)5312 Dept of the Navy BuAer on contract No. 52-2002 Copyright 1951 by Ethyl Corp. It is a comprehensive guide to aviation fuels and potential aviation fuels and lists energy output, vapor pressure, octane rating, density and numerous other pertinent qualities of those fuels. It makes specific note of the potential materials compatibility problems when switching between fuel bases. -- Remove _'s from email address to talk to me. |

That'll come to a bit of a surprise to the 757 I just left standing on the ramp. Bertie |
