Been quite a few scare stories in the press about how E10 petrol - coming
here later this year - will damage many older cars. Much of it 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?


You're probably already using E5 petrol, E10 is just more of the same.

The biggest concern is that ethanol is hygroscopic, it absorbs water,
and you don't want a watery fuel stagnating in your fuel tank.
Especially if you only use your car once in a while.

You can get ethanol corrosion inhibitor to slow/stop these effects.

I'm surprised the equivalent of diesel bug isn't an issue?

As long as the fuel is dry or has corrosion inhibitor then it shouldn't
attack either lead (in old solder) or zinc (in brass).
