    Consider that LEAD is the problem.....as in lead into the atmosphere. Frankly, I'm amazed that some green group hasn't already sued the refiners of 100LL. When that happens, and it will eventually, if government doesn't get off it's rear, then WE have a problem.

    That's one argument in our favor. Of all petroleum based fuels produced and used, avgas barely registers on percentage produced. When you consider all the pollutants put into the atmosphere in a month or year, we don't even register when compared with other sources.

    That being said, I reluctantly agree that we need to be planning for viable alternate fuels. It's just the military in me, list the 'what if's' after you make a plan. In our case 'what if' 100 LL goes away in spite of attempts to save it? What's the best replacement? Something we have right now, like mogas? A derivative? Do we need to produce something completely new? Consider that we're in the same boat as the automotive industry. We can get by with low performance fuel in a low performance aircraft engine but not in a high performance engine.

    If you want to argue, remember that if 100 LL never goes away, then we won't need to switch.

    GAMI and Swift both have 100 octane fuels, GAMI even has approval for some planes already Swift is working on getting approval. The big issue as far as I can tell is the FAA won't just do or can't figure out how to do a fleet wide approval.

    I've noticed that the airboat crowd use a lot of airplane engines. What are they using for fuel? Have they had issues? I'm suspecting they just use whatever auto fuel is handy? Is the FAA making a bigger deal out of our avgas than there needs to be? I do appreciate the stability of the avgas and use it in everything from weedwhackers to airplanes. I have had issues with the gumming up and reduction of volatility of auto gas in the past, particularly after having been stored for a few months or more. Perhaps the current ethanol auto gas doesn't do this? ???

    Stay tuned. From the GAMI website. The EPA is coming out with a report regarding contribution of lead in the atmosphere from aircraft burning avgas.

    Following the exp scene like I do, whenever someone specs out a hi comp engine, built for 100 LL, I wonder if they consider discussions like this!

    Being exp @ 10-1, I have options other than 100LL. The only reason I use 100LL is I already have it for my certificated airplane.

    GAMI chose not to attempt FAA Certification. As I understood it, they saw the FAA certification to be so onerous and lengthy of a process, that it wasn't worth the expense for the questionable results. They chose instead to go via STC and plan to offer a free STC to every engine possible. Does that imply that some engines may not be able to use it? Possibly.

    Swift attempted, and is still attempting to go the FAA/ASTM certification. That process has dragged out for nearly a decade. Swift has now chosen to sell STCs for their fuel for $100 per plane and now say they plan fleet wide implementation via STC. Why have both potential drop in replacements had to go the STC route rather than certification? This clearly points to a problem with the FAA and their professional foot dragging.

    MOGAS issues. The big oil producers have actively pursued running Mogas off airports. FBOs and fuelers that sell Mogas are threatened with having their supply of 100LL shut off if they don't remove the Mogas sales. I ran Mogas exclusively for 10+ years until I left NM and retired to AR using a 110 gal tank and fueling rig in the back of my pickup.

    In AR, Alcohol free premium Mogas is readily available. However, all of the stations in my area now have an injector cleaner additive in the fuel that I have found to cause as much or more damage than alcohol contaminated fuels. (details of the damage and testing on my web site) The carb and engine was fine with it, but it will dissolve pipe dope from the pipe fittings and will break down epoxy resins and any plastics or rubberized fuel lines in the fuel system. The last station in my area that was carrying clean fuel without the additives lost his source of clean Mogas a few months ago, so I have no choice but to switch to 100LL for both of my planes for now. Mogas has always had an uphill battle getting onto airports and local supplies around the country, even at gas stations it is iffy at best.

    One other issue with buying Mogas. Most pilots that use it buy at the gas station and haul it to their planes. The fuel taxes paid there go toward the state and federal highway funds rather than the Aviation trust fund. And there are no flowage fees to support the State Aviation fund or the local airport.

    100LL environmental issues. I have little doubt the environmental issues to the public from 100LL are so far below the noise level as to be negligible. However, the lead contamination many mechanics suffer continues to go untested, unreported and usually unnoticed. Mechanics routinely exposed to inhalation of lead salts from bead blasting combustion chambers and regular exposure to 100LL fuel on their skin often times have abnormally high lead levels in the bloodstream, well beyond the EPA acceptable limits, and often times with devastating effects. That grumpy mechanic that acts like a mad hatter might just be that way thanks to his chronic exposure to lead. It's only a matter of time until some smart enterprising lawyer decides to bring a class action law suite against the oil companies in behalf of the many thousands of mechanics with chronic lead exposure, that could also spell an end to 100LL and would certainly discourage the oil companies from continuing to produce it.

    100LL is a threatened and endangered species. As well it should be. If the AOPA will lead the way to support a transition away from 100LL as rapidly as possible, they will have my support. Had the FAA supported this effort, 100LL should have died out shortly after leaded autogas decades ago.

    Can you elaborate on your "options other than 100LL"?

    In Washington, you can apply for a refund of the road tax you paid on mogas used in aircraft.
    They deduct regular sales tax & aviation tax from that refund.
    So I get a little jingle in my jeans, and also support GA-- a win/ win.

    Same in Idaho, I looked into it, but the paperwork involved was daunting. Your mileage and tolerance for that may differ! Same thing when I attempted to deduct the road tax from all the diesel I burn while operating my boom truck on a job site, instead of driving down the road, I was told I could, but not worth the hassle involved. There is something to be said for having as little involvement with taxing authorities as possible (keeping a low profile...) even if it costs me a few bucks.

    Be sure and donate your tax savings to the Aviation Trust Fund for improvements to aviation facilities.
