Mike:
To an extent I have no doubt whatsoever that you are spot on as to Chevron's
reason to making the statement. I also think that 99% of the auto fuel out
there is quite safe to use... I use it myself...but I think it would be
better if we could get a nice straight unleaded (small aircraft) fuel. If
not that at least a fuel that has been carefully handled and is ethanol
free.
I have seen some STCs that allow aircraft to fly on Ethanol contaminated
fuels. To a large part these STC's are held by a chemist who has been
testing the fuels. For my money I'd only knowingly put that stuff through a
rather expensive Lycoming or Continental engine if I was a test pilot....
with my personal chute and quick release doors.
In the meantime especially if you can get non-eth contaminated fuel what's
there is for the most part usable just remember to try to avoid over flying
heavily populated areas at low altitudes... Doing that will keep you in the
good books of the FAA too! :-)
Has any one out there used gas that has had the eth "washed" out of it? The
process is simple I'm just wondering if anyone has used it in a plane yet.
We can't get the stuff (E-anything) here or I would have tried it.

I appreciate your concern over fuel issues but I think you need to
keep in mind Chevron's motivations. I'm certain that their position
on auto fuel use in aircraft is largely driven by their attorney's
concerns over liability. They have now provided notice that they do
not approve of the use of their ground fuels in aircraft so they can
say as much in court if they are ever sued following an accident.
So, they've covered their backside. Go back to using whatever fuel
you have determined is appropriate for your application.

Tom,
Thanks for the link. I am currently rebuilding and hope to make some fairly
easy - as I build - drag reduction efforts. The only disappointment, though
is that I will not have before and after data that would be helpful to
others in the planning process.

I have been told that here in Alaska Costco gas doesn't have ethanol in
it. An 83yr old pilot friend of mine uses the Costco gas in his beach a
nd his experimental and showed me how to test for ethanol. Maybe some o
f you out there can confirm his testing. He puts water in the bottom fo
rth of a clear soda bottle and marks the exact height of the water level
. Then he fills the rest of the bottle with auto gas. He shakes it up
good and lets it settle. He says the ethanol will separate out of the
fuel and mix with the water. If the water level stays the same there sh
ould be no ethanol in the fuel. Does anyone know if this is right? Als
o when using auto gas, should I use high test or regular. I tried it 2
weeks ago with regular and my engine seemed to run a bit hotter and roug
her but it could be my imagination. The fuel savings would be huge but
I still worry since my tanks aren't sloshed. Layne Anchorage, AK Subar

Testing fuel for ethanol
The following test can be performed to determine the presence of ethanol
in gasoline.
On a test tube or olive bottle, make a permanent line about two inches
from the bottom.
Fill with water to this line, then fill the tube to the top with
gasoline.
Cover the tube, agitate it then let it stand.
Ethanol mixes with water and the two will separate out together.
Therefore, after mixing the water and the gasoline, if the water level
appears to have increased, then the fuel contains ethanol and should not
be used.
Ethanol fuels can damage the rubber and aluminum components of your
aircraft fuel system. Ethanol increases the volatility of fuel, and
hence the possibility of vapor lock also increases. Ethanol may vent off
at altitude, reducing both range and octane. For these reasons fuel
containing ethanol must never be used in airplanes.
We offer a ready made ethanol tester for $15.00.

Good post on drag......... just goes to show how the Kitfox is such a draggy beast.
When you go from aa 582 to a 912 S you gain about 30% or less more cruise
with more than 50% more HP .
For comparison on drag look at my amphib floats -- I only lose about 5mph cruise
with them over 21" tires.

This is the official test to determine how much ethanol is inside the
gas
here, in Brazil, where all fuels contain ethanol. All gas stations have
a
graded glass and, by the force of law, have to make the test you
described
(mixing with water, shaking and measuring) everytime a consumer asks for
it.
The laws determine the alchool percent in any kind of gas, and it varies
depending on production disponibility and other policies.
As I said before, we have decades of experience runing engines either in
real ethanol and blends with gas, and we all know how much damage it can
cause to all parts of engines, exaust, carburators and other. If an
engine
is not specifically conceived to run on a blend of gas/methanol, please,
use
AVGAS.

If it is a stock Soob, it ran just fine on regular 87 in the car and
should in the plane. Now if you raise the compression, that makes the
difference between using reg or 92-92,whatever. Correct me if I am
wrong folks. Been there before. Larry

First off I am not in favor of ethanol by any means. That being said I use it
as I have other choice. And I use over 1000 gallons annually in my Kitfox alone.
Rather than posting the fears and or myths why not let compare notes on what has
in fact happened with continued use of ethanol gas. I will tell you that I must
be lucky if any of these myths are actaully fact.
Ethanol Gas is likely better for Rotax engines than is AVGAS but yet many chose
to run avgas. ?

Hi Lkc,
Most engines that have an 7.5 to 8.5 compression usually have no problem running
on 87 octane fuel, like some of the Lyc, Cont and the Rotax 912 80 hp.. The
engine like the Rotax 912ULS 100 hp has a compression of 10.5:1. This requires
91 octane. Engines have been running on ground based fuel since the Wright Brother's.
Your engine Mfg. can tell you if it is ok to run 91 octane and now days
it is usually published in your operators handbook. Your friend is right on
with his concept for looking for alcohol with the water test. You can over do
the water and fuel mix and you can read online on numerous websites on the exact
method. Aircraft Spruce has a couple of alcohol test available. If your temps
climb, but not too high it's a minor issue. If you have any pinging or detonation
then you need run run 91 octane. If you only require 87 you can't go wrong
if you up the octane to 91. The octane increase just helps control the burn
and stops any excess heat from causing possible detonation. Detonation is really
bad.

Hi Noel,
I think that's all anyone wants is some fuel we can use with no alcohol. Many people
like the unleaded 91 because it's cheaper and less damaging to their engine
than the leaded stuff.

Hi Dave,
I have to use ethanol, too. I am currently doing so research and testing with engine
temps, vapor pressures combined with OAT and how they affect fuel pressure.
I have used many a gallon with it in several planes. Don't get me wrong I
will go out of my way to get ethanol free fuel if I can find it. I have used ethanol
fuel in three Rotax 912ULS engines. Rotax says 5% ethanol is ok, but won't
put in writing yet anything higher like the 10% we usually see. I do know
in some areas of the world they have to use ethanol based fuels up to 17% and
they have not had any real issues at least in the Rotax. I prefer personally
to use the ethanol 91 octane over the 100LL. It's a personal choice. I have taken
apart and seen to many engines and the leading damage, not to mention twice
the maint. The possibilities of an issue could happen, but it's not high on
the probability list and of course this all depends on altitude, how you fly
and where you live in the world, ect, ect.. Your plane's construction also plays
a part in how ethanol will work for you (i.e. temps). The difference is that
people need to be educated about its properties and limitations. The idea behind
the memos was not to start a scare or issues between flyer's, but was in
some small way to let the major fuel companies realize we need some alternative
and they can not always sit in the office and just say no. 2010 is coming quick.
It's education ,education.

Ethanol is a great fuel, more powerfull, cheaper and less poluent when used
with the proper engine.
The detonation of ethanol requires more compression rates, so the first
ethanol fueled engines couldn't run on gas because they were built for
ethanol.
Now we have the absolutelly safe "flex" technology that allows an engine to
run either on gas, ethanol, or any blend of them, but this required years of
research and the engines have an injection computerized system that "reads"
the fuel composition and performs as it has to be. The engines have also
higer compressiom rates to burn alcohol and are stronger to bear the burn of
gas at those rates, and other developments.
There are also many certified air engines and certified planes flying on
100% ethanol here, in Brazil (the world's largest ethanol producer and the
first to adopt the use of it in cars in large scale, more than 20 years
ago). Very safe for flying, but the hole project was directed to it (engine,
tanks, exhaust system, injection, materials, filters...).
What I want everybody to understand is the fact that we have to observe what
the engine factory writes in the manual. That's all.
So, when Rotax, Jabiru and other tell us formally that we can use ethanol,
they'll also tell us how much of it a fuel may contain. Because there's no
freedom of choice of % . There are narrow limits unless aviation adopts
today"s modern bi-fuel car tech.
So, lets just ask them and let the factories publish their instructions and
follow it.

Hi Noel,
I think that's all anyone wants is some fuel we can use with no alcohol.
Many people like the unleaded 91 because it's cheaper and less damaging to
their engine than the leaded stuff.

I'm sorry, Roger if my bad English could cause a wrong impression on what I
really want to say.
We have lots of Rotax powered planes here, and some of them failed after
fueling with car gas. And we also lost some lives .
I'm just worried about the fact of too many pilots buying fuel at the gas
station and flying. Although the engine may burn some ethanol safely, we
cannot trust the control of contamination levels and the real composition of
the products at a car gas station, where they're less commited to safety
than to profits. And don't think just of engines. What about the lines,
pumps, filters, tanks and everything that may be in contact with the fuel
and the gases it produces?
I'm a private pilot since 1987, and I'm not an engine expert, but I'm
wishing the safest flying to everybody.
And let me tell you how much I appreciate your efforts to elucidate those
questions to all of us.

Hi Espuny,
I have found that most pilots are fairly well educated as to fuel use in
their particular engine. Some engines can handle ethanol and some can't.

Subject: naca inlets
hi all,
lots of thoughts about creating a negative pressure inlet to pull air
from the cockpit. i feel a simple test coming on with a leaf blower and
a manometer! first i have to build a conventional naca into my cowl.
a friend gave me a demo of how effective teardropped shaped fairings
are. he had a set up with a leaf blower and a way to measure the wind
force against a broom handle . then he slipped a fairing over the length
of the broom handle. it was like magic. the pressure against the broom
handle was now about 1/3. anyway, i will look into all this in the next
few weeks after i install my first naca.

Yes, you hit the nail on the head Larry. I was told the same from guys who work
at the tank farm here locally. They basically you have no idea what % ethanol
is in the gas from time to time and it can and will change.
Octane can vary as well. Rotax 2 strokes and 912 UL and 914 are fine in Regualr
grade. The 912 S with higher compression does like Premium grade better.
AVGAS -- will add alot of lead to your engine - 2 or 4 stroke Rotax. Rotax does
not recomend AVGAS >period !! but many seem to think it ok. ?

My ASI was leaking on the static side. I replaced it about a month ago from the
guy on eBay. ...Although...It was $67 at that time. They are new, but the
documentation paperwork shows that mine was inspected in 1989...So it is old...but
new and was still in sealed factory wrap and was well boxed and protected.
And...Is working fine.
