As a Porsche owner I can vouch for that (2002 996 Carerra Coupe).  
Once a year I head out for a National Championship in Topeka, KS.  
Once past St. Louis, the "premium" grade gas is 91 octane. The car  
seemed to have run fine to and from Connecticut. Porsche specifies,  
93 or better which is plentiful out here in the east. I am sure  
Porsche's OBDII controllers would be much happier at the higher octane.

My 1996 BMW 318i (OBDII controls) is also the same way. It does seem  
that it runs better at the lower octane, but I am too superstitious  
to run a lower grade at the Championships.

A Porsche engineer pointed out that their cars had to operate at
times in countries where there is no premium gas oor even midgrade
and work and standup.
