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.

Your alka seltzer fizzes in water. It all by itself does not detect alcohol...

And now for the rest of the story....

Step 1....
Got a clean urine sample cup - meaning unused...
Using a sterile syringe I added 1.5cc of denatured alcohol (S-L-X
brand) from a previously opened can, which will have an unknown % of
absorbed water vapor, to the sample cup...
Dropped in a small chunk of Alka Seltzer Original...
Faint fizzing noted - you will have to be gimlet eyed to see it - but
it does fizz... So, we can assume that "pure" alcohol ( a weak
organic acid that always contains absorbed water) will 'fizz' Alka-
Seltzer (contains bicarb of soda) if a bit faintly...

Step 2....
Added 0.4 cc of warm weak tea ( it was handy) in 0.1cc increments...
Fizzing rate essentially doubled, or a bit more, by the time I reached
the 0.4 cc value... Easy to see... This is 26% imbibed water in the
alcohol... Dunno what effect the pH of the tea had - I assume that
word that it might enhance the fizzing from the bicarb...

**** the intellectual reason for the tea besides it being in my hand
is that water condensed on a metallic surface will be weakly
acidic****

Step 3...
Dumped the liquid from the cup and added a dash of tap water...
Fizzing about tripled the rate from Step 2...


Alka-Seltzer does not fizz explosively, like Arm&Hammer bicarbonate of
soda would because it is buffered with citric acid... you will need
to google on buffering and rate of reactions to understand some of
that

Unfortunately, for scientific rigor, I do not have any so called
gasoline handy to test with... I have one minute to start seeing
patients and I suspect they will not be impressed of I reek of the
nasty crap they sell for gas these days...

Thanks Denny, good post, esp. the "so called gasoline" comment...



Went down to 'the shore' the other day and was able to check out the fuel pumps for the boats. The label on the pump
said "100% Pure Gasoline". So, the implication here is that unless you see a label that says 100% pure, you are most
likely getting gasohol. There needs to be a lawsuit or something to get the pumps labeled correctly...
