My '04 FX35 went over 16K on 87 regular with no indication of problem, my new '06 says in the manual that it will run on 87 but "for best performance" to run 89 to 91.
Since I don't do much "performance" driving, I'm sticking with the 87 unless I start having any problems.
Perhaps there may be some long term advantages for feeding the higher octane, but since I don't keep a car more than a couple of years and usually only rack up 15-20K miles I don't see much advantage for me.
