Mine are around -6 (2000 Boxster S, 130K miles), I talked to some folks about getting it done, and one of them said to come see him when the CEL comes on, which I think (I may be recalling incorrectly) he said was at +-9. I check it from time to time and it has been holding steady over the 30K miles I have owned the car.
