It is becoming difficult to find non ethanol polluted fuel around here and
it appears that eventually all available unleaded fuel will have ethanol
added. I am debating about what to do. Currently, most of the fuels
contain a 10% blend of gasoline and ethanol, but the ethanol lobby is
pushing for a 15% ratio mixture. The only apparent alternative is 100LL
which also presents some issues. I am considering a blend of 100LL and
ethanol fuel. By using a mixture of the combination it reduces the ratio of
the ethanol in the fuel and the lead in the 100 LL. I am also considering
adding TCP to scavenge the lead in the 100LL. Does anyone have any
information on how effective TCP is reducing the harmful effects of lead in
the 91X series of Rotax engines?

Just installed a soft start module on my 912uls. Works like they say and I
would recommend it to anyone. Helps save the sprag clutch and the gearbox.

Dan--
Rotax has ok'd the use of ethanol at a 10% level. Up here in the northeas
t we've pretty much only had ethanol based fuels as mogas for 3-6 years. I'
ve used it in both 2 stroke and 4 stroke rotax engines for 6 years with no
issues.
When I fly xcountry I'll use 100LL with TCP. The TCP works well at scave
nging the lead out. If you don't use TCP wth 100LL you will need to chang
e your plugs about every 25 hours

TCP has to be burned to work. If your engine is a two stroke it will do the
square root of sweet nothing to protect your main bearings from having lead
plate out on them. It will however keep the top end of a four stroke engine
and the exhaust valves pretty clean.
Ethanol is a scourge we are all going to have to learn to live with for the
short period at least. It will die shortly after the governments of our
countries quit shelling it with our money. In the meantime I suggest;
Getting as close to ethanol proof tanks as is available, Never leave fuel in
your plane after a flight unless you know for sure you will be flying again
in less than a week, Always buy your fuel from a very busy station as their
fuel tends to be fresher.
If you feel a little adventurous you can always wash the ethanol out of the
gas. To do this you simply add as much water as is required to cause a
phase separation in a separate container then siphon off the clean gas. A
couple of problems with doing this is removing the Eth will lower the octane
rating, finding a good octane booster that actually works may be a problem.
Also you will have to treat all your fuel so trips to distant strips may be
out. As far as I know MTBE is not available on the open market.
I also recommend writing your congressman, Senator, Members of parliament or
whoever and explain to then the danger they are causing by removing clean
fuel from the market. I only wish there was a way we could collectively sue
them (Politicians) the first time a crash occurs that is proven to be the
result of Ethanol contamination.
Just for the record if you are really desirous of clean fuel you can always
come here to Newfoundland ;-) where there is still no ethanol in the gas. A
couple of years ago a ship load did come in and the story I got is shortly
afterward it had to go for refit as all the holds started springing leaks
caused by ethanol corrosion. A federal law recently enacted requires all
service stations in the Dominion to sell 10% eth gas within the next four
years. Being that large tracts of the country do not produce corn and there
is no known way to efficiently transport the crap yet I have my doubts if we
will be forced into ethanol in the next four years. Come to think of it
it's hard enough in some places to get ethanol at 80 proof in glass bottles.

Actually, I just asked about Decalin Runup and if anyone knew much about its affectiveness
with 100LL over on the Kolb list a little while ago.
Probably good to ask that here?
Both E10 and Decalin Runup (as well as TCP) have been approved for use in the rotax
4-strokes so at least our engines are covered for the time being. We can
use either fuel. I've been using E10 (the only unleaded available here in NM)
for about the last 4 months with no apparent problems. I very carefully monitor
my fuel filter both pre- and post-flight to check for crapola. I also start
robbing gas out of the plane and putting it in the pickup once the plane sits
for 2 weeks.
Once we go to 15%, and don't think for a minute our govt. is smart enough to not
do that, we'll have no choice but to run either 100LL full time or a blend.
I'll probably go to the blend for local flying and 100LL when I take trips.
I'm going to try the Runup in future when I run 100LL to see what results I get
(if I can even tell what the results are ;)).

Hi Dan,
If you have to choose between ethanol and 100LL, then ethanol is the lesser of
the evils. The majority of the people use ethanol now days and they aren't falling
out of the air or replacing their engines because of it. I will use ethanol
laced fuel over 100LL any day. If you saw what an engine and slipper clutch
looked like after a lot of 100LL you would stick with ethanol, too. I personally
wouldn't even mix my fuel. 100LL is hard on engines even though the Rotax
can run on 100LL for its life, but there are consequences. Cut the plug and oil
change intervals in half or pull other parts off to clean out the lead. The
ethanol is nothing to the Rotax. Most fuel tanks are ok with ethanol. TCP has
some harsh chemicals and not supposed to be kept in the cockpit. Most people I
know use Decalin. It does the same thing as TCP, but without the harsh chemicals.
You use 1/2 oz. per 10 gals. Get it from Aircraft Spruce for about $16.

& all
Here in Europe the alcohol is added at the distribution centres. There
is _no_ check on which fuel it goes into so even the oil company cannot
tell you what is in the fuel you are buying. They just have to confirm
they have sold certain %age of "biofuel" IMHO it is madness and
downright disgusting.
Typical political trickery, as always we pay, they get the bonuses.
