Don't think this guy is impressed with a report by the Department of
Energy that is pushing to increase the percent of ethanol in
gasoline:

E15 is a bad idea to increase "renewable" fuel and probably won't fly.
But E10 came about because the Clean Air Act demanded that gas be
oxygenated to lessen air pollution. MTBE was used as an oxygenator,
but
was found to pollute ground water, so E10 came into use. Of course
that
was also influenced by lobbying, but people seem to forget the primary
purpose of E10 is to provide oxygenated fuel and cleaner air.
It's been around for decades, and Mercury Marine has no issues with
it.
The engine failure in the above YT vid had nothing to do with E10, and
if fuel line particles hosed an injector (the actual lean-run cause)
it
was most likely the owner screwed it by using cheap-ass fuel hose that
was not in spec for fuel. Certainly wasn't fuel hose supplied by
Mercury. Fuel hoses have been E10 compatible for about 30 years now.
Likewise, E10 probably played no part in Harry's fuel bowl corrosion,
despite his mower mechanics voodoo thinking. Water has intruded into
fuel systems and caused corrosion long before E10. Fuel care isn't a
new subject.
This is an excellent fuel care and E10 explanation from Mercury
experts,
debunking E10 myths. But it's long, and full of detail, so be
forewarned.

Scroll down a bit and play the vid. Sound gets better after a few
minutes. You might just start at about the 4 minute point, and skip
the
into.

There are all sorts of studies, reports and anecdotal stories about
ethanol in gasoline, probably as many pro as con. The EPA mandated
the auto industry to design cars to run on E-10. For many years gas
sold at marinas remained ethanol free, but eventually the marine
industry had to follow suit and design fuel systems and engines to run
on E-10 also.

One of the biggest problems with E-10 is consistency in the mixture
ratios. Gasoline and ethanol can't be pipelined together. (I wonder
why). Ethanol has to be transported separately by truck or rail car
and then mixed. It doesn't take much more than the 10 percent in
E-10 to cause problems that several car manufacturers will not cover
under warranty. BMW, Toyota, Nissan and others required a fuel
sample to be taken and analyzed prior to certain warranty engine work.
If above 10 percent, the warranty is not honored. There are
documented cases where the ethanol content was as much as 18 percent
in gasoline called "E-10".

So, the manufacturers can design a car or a boat engine to run on 10
percent ethanol. But how much ethanol is really in the fuel?
I'd say it's fine to require new boat and car engines to run on 10
percent or 15 percent, but regular, plain ol' gasoline should also
be readily available for those with older vehicles and/or engines.
