I've been doing UOAs and winter storage of Porsches for over 13 years. Some years the oil has as little as 200-300 miles on it at shut-down-time. Other years, it has 2,000-3,000 miles on the oil. On rare and perfectly timed occasions, it's been as low as 20-30 miles. My UOAs have all been excellent, and I've never seen any indication that the mileage mattered. My cars get driven during the driving season, use high quality A40 approved oil, and change every 5K miles.
