Heh, not going to happen, I don't lay the bike up over winter. I think the longest I've gone between rides is 5 or 6 weeks when the winter weather's at its wettest.

However, when E5 was introduced, I had my GT380 and there were all sorts of dire warnings in the classic bike mags, forums etc about how it would rot fuel lines, rubber parts in carbs, tank liners, crank seals etc etc. I had no problems with any of that.

Thanks for some actual facts Embee, not enough of them in the world of bikes alas

There is an article by the editor in my local parochial newspaper illustrating how corrosive E5 unleaded petrol has been to the plastic petrol tank of his 1999 Triumph Daytona. He is now on his 4th plastic tank and has commissioned a specialist to build him an aluminium tank as he says 'E10 will eat through the current tank in no time at all '.
He obviously thinks ethanol damages plastic.

Depends what the plastic is. A lot of plastics are perfectly fine with ethanol and petrol/gasoline, some aren't. It's up to the designer to specify something suitable.

from MCN:
Triumph Daytona 955i used buying guide
There are a number of things to look out for on the Daytona 955i, including:

• Fuel tank - Modern ethanol-rich fuels can play havoc with the plastic tank if left to sit in it for too long, causing it to swell, go out of shape, and fuel to leach under the paint.

.... just to add, you'll probably struggle to find a reasonably modern car which doesn't have a plastic fuel tank. There's plastic and there's plastic .......

You would hope the plastic is suitable for petrol containing ethanol.

So Triumph apparently didn't specify a plastic that was suitable for petrol containing ethanol !

Note : In the Suzuki SV650A handbook it states be careful not to spill petrol on the tank when filling up as ethanol can damage paintwork. Not that anybody does that deliberately but I did just that the other day ,as I turned the pump handle to face the filler hole petrol spewed out from what must have been left in there from the previous customer filling up.
