You're most likely throwing money out the window, and possibly performance. I used 89-91 for a long time when I first got my car and didn't know any better.
Now I run 87 and use Techron injector cleaner every 3000-4000 miles and everything's good. In fact, I recently used plus gas (89 i think) for a couple of tanks to see if I noticed a difference, and I honestly didn't.
