I can get 26mpg on the highway @ 70. Suppose I might eke out 28 if I could go 450 miles non-stop. Ain't going to happen, though. I CAN routinely average 23+ in 70/30 mixed driving, though. All this with an M104, that I've been told is more efficient than the older M103.
In short, if you can ever see 29 with an M103, that's a 1 in a million keeper... On another note, I have experimented the last three fill ups with running 89 octane instead of the 93 octane super we get here. Mileage seems to be the same, but I'm probably off a little on 0-60 time. Nothing quantifiable, just my seat-of-the-pants dyno.
