The European method, or the German method at least, uses the RON octane
rating.  We, Yankees with big nukes, use a different method of calculating
octane and the name escapes me at the moment.  91 RON octane is about 87 of
ours.  If I am wrong I'm sure someone will correct me.  It never fails.  I
still have the nukes, so watch out.
