Yeah, I was always surprised when I took my K75S motorcycle to ride the Colorado mountain roads rather aggressively -- I actually got better MPG than cruising across Nebraska or Kansas. Apparently I picked-up more on the downhill with the injectors turned-off that I lost on the uphill with heavy throttle.

I can peg that '99.9' regularly, in the ol'X5, or the ol' Vette whenever I idle down our 4 mile mtn road, in gear with no gas. Both are manual trans cars, fwiw.

Pretty normal, imo.
