has anyone noticed any difference in the stryker's performance while running any different grade of fuel? (mileage, performance, noises...)

Here in Colorado our low octane is 85, 87 is mid and 91 is high. My understanding is that because of the altitude 85 here is the same as 87 somewhere else. Any thoughts or advice? My bike seems fine on 85, but should I move to the 87 mid grade?
