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

here later this year - will damage many older cars. Much of it the usual

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.

Where would this water come from?

From the air in that soggy little frigid island.

Would the moisture in the air (that replaces
the petrol) be sufficient to cause a problem?

And what gets pumped in by the thermal
cycling of the petrol tank every day.

Does this depend on temperature?

In the sense that the thermal cycling does that, yep.
