Been quite a few scare stories in the press about how E10 petrol -

the usual press ********, after all E5 has been around for quite some
time, and is known to attack older 'rubber' flexible fuel pipes. Which
don't last forever anyway. Much of it generalization, but one specific
was mentioned.
It attacks the solder used on carburetter floats (those made of brass).
Any comments?

I can remember when unleaded petrol was being phased in, and some
cockwombling fire chief scored weeks of publicity saying it was a bad
thing as it was more flammable that real petrol.

Which suggests (as always) the 80:20 law still applies, and 80% of
reportage is utter ********.

Now if he said it was more carcinogenic he would have been right, from
the increased levels of benzene and other aromatic compounds.

Thought alcohol is in general rather clean burning? Are you saying it is
worse than petrol?

What I am trying to say that when unleaded fuels entered the market they
were toxic. You wouldn't want to inhale the vapours or get any splashed
on your hands.

As time has progressed there are new regulations with limits on the
aromatic content.

The octane rating of ethanol is quite high, so less of a need for these
aromatics in E10.
