I'll fill-up 2-3 times per week depending on how many miles I drive.

I've never tried 87 Octane in my 325xi but will float between 89, 91 & 93 octane. While I don't notice any performance increase... I DO notice that the higher the octane the slightly better fuel economy I get.

89 = 23MPG
91 = 24 - 24.5MPG
93 = 25 - 26MPG

This is something I have kept an eye on for the past 6 months.
