It's stock, mostly. Just lots of P&G, and a pretty good route. (low speed limits, few lights, multi-lane so traffic isn't a problem) It's dropping a bit now, with cooler weather and a new school dropoff routine.
It's got 181,000 miles on it and the clutch and transmission are holding up just fine. I believe member basjoos got 500k on his original clutch, too.
Another member has confirmed that the Ultragauge will keep calculating mileage in EOC. Try it in a parking lot and see.
