Mein Auto: B8 S4, E70 X5d
i always run 93 but its usually because it was a car that made more power with 93 (turbo, sc, tune, strung-out e46 m3 LOL, etc.). while i can't comment on the x5 specificially, i know that when we had our Q7 3.6Q, it got significantly worse mileage with 87. and not just around town, but on 4 different trips from houston to dallas (250 miles), travelling the same route.
