My Ford Focus SVT is the same way.  It's got the variable 
cam timing engine and requires 91 minimum.  I used to put 
mid-grade in it and it was fine, but I swear they cheapened 
the gas up or something as I can't do that now or it 
clatters like a bunch of cans behind a newly wed's car.  
Add to that the fact the price differential between grades 
used to be .10 per gallon, but now it's .13 or.14 it's 
frustrating as heck.
