I'm looking for a 912 technician in the Northeast U.S. Someone within
a couple hours of Bennington, Vermont who is willing to travel. The
R.O.A.N site is not providing this information just now. I have a 912
ULS nearing completion of installation and some friends who could also
use input for their 912's. We could set up a day's review of our
instalations, possibly including a first run and purging of the tappets.
Answer on this site or email docponds@sover.net or call home

I fly an Allegro 2000 and use Mobile 1 Racing 4T 10W40. It is a fully
synthetic oil with the proper additives for the gear box. I do not use 100LL
fuel, only 87 AKI MOGAS. The Rotax engine is set up to use MOGAS. I would
only use 100LL if I found my self at an airport low on fuel, and I
absolutely could not find a way to get any MOGAS. Everyone has there own
opinion, but for the life of your engine, that's my opinion. Use your own
best judgment.

I use the Mobile 1 4T racing oil too, and on a long cross country I had to
use some 100LL for a few hours. I changed the oil when I got back and could
see the lead had settled out in the oil sump. The spark plugs were also
caked with lead deposits. It took a second oil change 20 hours later to get
rid of all that lead.
I am thinking it would be wise to switch to a semi- synthetic blend so that
these problems are minimized when and if forced to use 100LL. Does anyone
have any thoughts or knowledge regarding switching to a different oil after
running the engine for 130 hours on full synthetic? Are there any issues?
What are the disadvantages of using semi-synthetic oil?
I have started carrying an empty light weight plastic 5 gallon can suspended
in the empennage when I go cross country so I can get mogas.

Jack:
So far, I have been able to plan ahead and call the airport where I plan to
stop and ask if they can arrange transport for me to get to a gasoline
station and borrow a 5 gallon can to get MOGAS. I have not started carrying
a plastic 5 gallon gas container in my Allegro 2000 for a number of reasons.
Even though I have not tried it, I believe that even though the container
would be empty and closed, but has had gasoline in it, it still gives off
enough fumes that over a 2 or three hour flight the fumes that would be in
the cockpit would be detrimental to good judgment, and give you such a
terrible headache you would be praying for an airport to land. Second, if I
could find a way to directly vent the escaping fumes to outside the cockpit,
I like you would indeed carry an empty 5 gallon plastic container with me.
Any ideas how I could safely direct vent the fumes??

Hugh,
Good point on the fumes. I fly a Sky Ranger, a nice breezy airplane with
plenty of airflow. I just make sure the can is as empty as possible, and I
am not able to smell anything. You would have to rig a tube from the can
vent to the outside, probably more trouble than it's worth.

Jack:
Maybe not! I can drill a second small hole through the bottom of my
fiberglass composite fuselage near the point where the main fuel tank vent
is now located, and protrude a second vent line from the plastic can. It
seems to me that this would be no different that the existing main fuel tank
vent line. I would have to come up with a "one of a kind" cap on the can to
connect to this line. The vent line would protrude perpindicular to the
fuselage, but if I beveled the protrusion similar to the main tank vent line
it should vent properly.

No John,
I'm not a competent chemist and my spelling gets clobbered by my typing,
but a proper formulated butanol doesn't absorb water, is a better
solution than ethanol
not competing with food products and doesn't require huge amounts of
water to produce. I think they are still considering these aspects or
hope they are.
In areas of ethanol production, the dropping water tables affect large
area access for everyone here with well water.

No. To produce ethanol you need to start with
sugar or a starch that can be converted to sugar.
There's R&D of new ethanol processes that can use
cellulose, but that won't help you either.

Old sugar/ethanol plants used to drop their garbage into the rivers and also
polluted the air very much. Nowadays, there are filters and water treatment.
The government inspects closely the process and the industry does not
pollute anymore. Fines are heavy. The only problem is that the farmers still
burn the field to facilitate the handcutting of cane. Laws determine that
the use of fire will end in two years and the majority of farmers are using
big machines to collect the cane, so it's not necessary to burn the leaves
up and production is faster.
The bagasse is burnt to run the boilers or are hidrolized to feed confined
cattle, and some refuses are used in animal food and other are put back over
plantation as fertilizer.
Water is not added to the cane itself, but used in cooling and cleaning. The
sugar cane is naturally made of more than 70% water. It's different from
making alchool from corn or grains, wich have to be wet before fermentation.
The treated water is given back to the sources.
Of course the process is not perfect, but is getting a lot less dangerous
for the enviroment.

Assunto: RE: RotaxEngines-List: Re: Butenol???
Just wondering out loud.... Can ethanol be made with sewage water??? Or is
it too toxic for the fermentation process? Funny i never considered the
whole idea of water necessary for production.

No John,
I'm not a competent chemist and my spelling gets clobbered by my typing,
but a proper formulated butanol doesn't absorb water, is a better
solution than ethanol
not competing with food products and doesn't require huge amounts of
water to produce. I think they are still considering these aspects or
hope they are.
In areas of ethanol production, the dropping water tables affect large
area access for everyone here with well water.
