[U-96]

2003, 2.7L, approaching 100K, most of it - short city trips, half of which are in ugly New England winters.
I change oil twice a year, use fully synthetic Mobil 1 (switched to High Mileage flavor at ~80K), winter - 5W-30, summer - 10W-30.
Never used anything but OE filters.
Knocking on wood, but no problems so far: the engine purrs like a kitten, no oil leaks or excessive oil burning, the MPG is in expected range.

Seriously?... I can hardly imagine how bored should I be to do it for a 10-years old beater.
