Given the issue with alcohol, and the fact it is injected at the

running campaigns to set up procedures for FBO's to procure untainted
autogas?

I really doubt that the terminal operators are so ignorant as to make that a
problem.

Ha!


OTOH, there are some real problems for the FBO to overcome. One FBO owner,
who I know, stopped selling gasolene several years ago--saying that he
sometimes suspected that he lost more to evaporation than he pumped.


That's a "selling autogas" problem;
vice "finding un-Ethenol'ed autogas to sell" one.

Agreed the first may be an issue..

BUT if you have a gaggle of STA'ed aircraft owners based there and
you but not evry EatHerAndGetGas sells what they want and need....




If this special clean gas w/o alcohol is brought to the airport and kept there, doesn't it pretty much miss the point of
the autogas STC? The whole idea was to be able to use normal autogas in these old low compression engines.


No, the point was to be able to use gasoline with less lead than the
currently available 100LL AvGas whick gives many older engines
"morning sickness" due to lead deposits making valves sluggish.

I thought one objective was to avoid using the 100LL in engines that were
prune
to lead fouling.

Wouldn't prunes give them gas?

Nope. He was talking about an old engine. It needs the prunes to keep
the works from gumming up. I think most of the guys here know that. 8*)

I wonder if prunes work on old engines, like they work on me?

It would give the engine exhaust a certain.....

Yes, that it would, but beware of potential backfires.

Although gas might be a byproduct, prunes are primarily an agent for
cleaning out all the old crap which should leave the engine nice and
clean on the inside.

Yes, but would the gas be Mogas or 100LL?

Prunes are "nature's dynamite and will clean out old or new pipes
regardless of what you've been running though them. They add a bit of
color to the diet.

There are really three of issues (that I can recall) he
1) A diesel will run on any hydrocarbon fuel that it can pump and meter.
2) Different seals and hoses are compatible with different
chemicals--although it would be no surprise to find that all were compatible
with biodiesel.
3) Certified aircraft/engines require fuels authorized in the type
certificate and/or an STC.

4) Biodiesel supposedly thickens at temperatures that pilots fly in.


As does regular diesel fuel. The stuff will gell up here in winter so
I'd expect to see biodiesel durn near turn solid.

Though it can be corrected with additives, I would rather have heated
wings (thus tanks) to avoid additives and gain de-icing capability for
the same feature.

Additives are much more reliable so you have (how ever many tanks)
less items to fail in winter.


Has this been done before, or do de-icers only heat the leading edges
of the surface?
