True.  At least one UK member runs 50% AVGAS, which gives him a minor revenue 
duty problem.

The European incarnation of the ur-quattro engine at that point is designed to 
run on 95 RON - it sayeth so in the microfiche.  The filler flap, however, says 
'98 RON'.  Well, you can't get that here now, even at exorbitant prices.  The 
current premium 4-star (leaded, still) fuel says '97' on the pump handle.
 
We _can_ get 'Super Premium Unleaded' at 98 RON - but it's _HIDEOUSLY_ 
expensive.
