What I read is that rubber parts were manufactured with a very thin coating of varnish to protect them on the shelf. The 10% ethanol will dissolve this varnish over a very long period of time, not the rubber though. The difference to your CIS will so slight, it will not be perceptible.
In your engine, oil breaks down over time and leaves a varnish deposit inside the engine. It is the brown coating you see when you split the cases on a high mileage engine. The tiny amount of ethanol in the blow-by gases will eventually clean the varnish coating from the parts and you will dispose of this when you change your oil. Good, no?

I maintain that 10% ethanol will do no harm to our cars other than reduce the mileage slightly.

This thread was never really about E85 but "beepbeep" added that as an aside in the third posting. Goran has shown that in Sweden E85 is a fact of life. Here is a bit of trivia from wikipedia nonetheless:
As of 2008, there were an estimated 7 million Flex-Fuel capable vehicles on the road in the United States. A recent GM study found that roughly 70 percent of its flex-fuel vehicle owners didn't know they could use E85, and fewer than 10 percent did so.
