My experience with my 95' 900SET, is that with 92 Octane gas I gett approx. 24.4 - 25 MPG; with 93 Octane gas the MPG drops to approx. 22.4 with no noticable change in performance. My next step is to try with 89 medium octane. The owners manual recomends from 87 to 92. So now for me, 93 is out. Elliot
