I dont think so.
I'd try out the other ones just to see if theres a difference in performance/mpg.

yes, 91-95 octane is highly recommended to get the best performance, mileage, and life out of the vehicle. I did meet a guy that used 87 octane in his Eclipse though, and seemed to do OK, but i see a difference in my own car b/t teh 91 octane and 93 octane, so you will see a HUGE difference b/t 87 and 91.
These cars also dont' recommend the use of ethanol blend, most 91 and higher octanes don't have this blend and so cause the car to run better.
YES OCTANE MAKES A DIFFERENCE!! (clarification)
