How blue is 100LL?

Robert,

Next time try pouring a few ounces of the fuel onto the ramp. Fuel will soak
in, but water will bead up.

The effect isn't the same on grass.

Years ago, I almost made myself pass out
smelling the fuel from the Aeronca. I couldn't convince myself whether
or not I saw blue (I wasn't worried about mogas, I was concerned about
water since it has just rained).

Yeah, sure... that's your story, and you are sticking to it. G

You're right, it can be almost impossible to tell if it is really
slightly blue. And at night, where there isn't any good non-biased
light source to use, it can be impossible.

One option is, of course, to ADD water to the sample. No "bubble" and
it's *all* water.

What I usually do is first drain from the engine fuel filter, under the
theory that since the engine was running at shutdown there must be at
least a LITTLE gas in there. If it looks good, then don't pour all of
it out, and now add from the left main. If it looks good, then don't
pour all of it out and now add from the right main.

The idea is that there should always be some known fuel in the tube, so
you don't have the risk of thinking an all-tube WATER sample is fuel.

That's a good idea. I wish there was some way to catch the fuel from
the collator in my Mooney.

And in Florida, gets you a $50,000 fine.

Hmm. Not aware of this. What do you do with the drained fuel then?

Don't get caught. That'll get you kicked off many airports and get you
fines in some
places. Gas damages asphalt.

If you don't tell lies, you never have to remember what you said.

I guess this comes from not flying for many years. What do you do with the
drained fuel?

I put it back in my tanks. When I had a 150 and was based at 47N, the accepted
procedure was to dump it on the grass, but *never* the asphalt. After I replaced the
cap gaskets on the 150, I never got any water in the fuel, so I've been putting it
right back in the tanks ever since. Never had any water with the Maule, either, so I
kept up the practice.

Pour it into a jerrycan (kept outside the airside door) and that's used to
run the lawnmower tractor that tows the Cessnas around. The Club doesn't
have to buy tractor gas anymore, and it keeps pollution/ramp damage to a
minimum!

Generally you use a capture bottle, and you return the sample to a
designated collector.

Hasn't reached this far, though I seem to recall such a deal in New
Jersey. (Where the fuel tank was above the surface, also I think
because of environmental worries.)

Besides, we don't have any asphalt
