"... Germans used a particular synthetic rubber that apparently was soluble in alcohol!"

A few years ago many cars were burning up on the freeways due to the "new blend" in gasoline (Los Angeles area). The gasoline was eating up the rubber fuel lines. Sounds like this is the same cause. Comments?

I would imagine that any time you put a new additive in gasoline, you run the risk of having it attack rubber parts.

Although you'd think they'd test it first . . .
