My Mustang will run on anything from 87-octane on up.  The specs say I get 
10ft-lbs more torque in the midrange if I run 
91-octane or higher.  It's pretty subjective--you'd have to put it on a dyno to 
be sure--but there is a slight, 
occasional hesitation when I punch it with the low-test.  It seems to run a tad 
smoother on the high-test, too.  I've 
mixed 93, 95 and 100 octane fuel in and didn't notice much difference (you'd 
need to raise the CR to get any gain from 
higher octane,  I suspect).  Again, totally subjective.

I don't know about Europe, but I believe there is a difference in octane 
ratings.  The refiners know what they're 
making, and unless there's a screwup you should be getting what the pump says 
(some brands only put their 'special' 
additives in their premium).  The Bureau of Weights and Measures checks the 
volumes the pumps dispense (I used to work 
there).  There should be a sticker on every pump showing the last time it was 
checked.  I don't know who checks the fuel 
octane--probably the refiner; I think that's a fairly complex test--so some may 
cheat, though.  Would make an 
interesting 'investigative reporting' episode.

What do you think of 'Top Tier' fuel?
