Hello JFP in PA,
everything you tell is right, but it is not a problem to use E5 or E 10 if you go for a journey and it is only E5 or E10 available.
The fuel system of the 986 is able to handle E10 without getting harmed. Please see Porsche approval above.
Found a more detailed information on ethanol fuel on Wikipedia:

Hello Robert993TT,
the german government decided that every fuel you can buy in Germany has to contain an amount of bio fuel in the year of 2006:
https://de.wikipedia.org/wiki/Biokraftstoffquotengesetz E10 was introduced in Germany in 2011.
Aral says they use Bio-Ether instead of Bio-Ethanol for Aral Ultimate 102:

Ether:
https://en.wikipedia.org/wiki/Ether
I'm not a chemist. Ether is made from alcohol and sulfuric acid while split off water. So it seems to be the better choice. They've used Ether in the past to get better knock resistance. But it was more expensive than Benzol, Tuluol or Xyol.
And as said, Porsche officially approves E10 for their cars built since 1947. So i see no big issues in using E5 for a journey to Germany.

PS: By the way, the guys that work at Porsche always use the cheapest fuel for their Porsche company cars when they're at the fuel station. They say that the car has to handle it.
