Is it true that there is no longer any requirement to label gasoline contaminated with alcohol?

Good article hehttp://motorcycleinfo.calsci.com/Gasoline.html

I just did the add water to gas test on a couple of local gas sources and all contain alcohol, and none of the pumps
said anything about it. The feds just dropped the requirement to label the pumps and we all missed it?

Jay, where do you fill the grape from and how do you know there is no evil alcohol in it?

When MTBE was outlawed, the only feasable alternative to add oxygen to
gasoline was alcohol. This is mandated in ceartin parts of the
country - mostly the east and west coasts plus mant of the major
cities. Many states have followed suit and now require 5 or 10%
alcohol to be add to auto gas. Some states require that the retail
pumps lable that the gasoline contains alcohol - some states do not.
Currently retailers can save money by adding alcohol to the gasoline
because the alcohol is less expensive than gasoline, so they can blen
it in and sell it to you as auto gasoline - you may not know it. Any
percentage of alcohol in the gasoline will void your auto gas STC.
There are many pushing for a national requirement for alcohol to be
added to auto gas.

Non alcohol auto gas will be available for FBO's to purchase and sell
as auto gas for aviation, but anyone buying auto gas at a retial
outlet and taking it to the airport in 5 gallon containers will need
to check it for alcohol. EAA has a method on line to tell you how to
check it. I recently did a presentation on auto gas with alcoho for
an aviation group, added 10% alcohol to pure 87 octane auto gas - then
some samples I added water - then lowered the temps on all samples to
below freezing.

First thing was that the alcohol would not stay mixed with the auto
gas - it would seperate out. Second thing is that alcohol absorbs
water - so you could not see the water in the alcohol/auto gas
mixture, but when the temp was lowered to below freezing the water
froze and ice settled out to the bottom.

All said - I will not be using auto gas in my plane - it looked like
an easy way to have a line freeze and turn the plane into a glider.
