Oil filter change vs oil change

Many years ago, back around 2005, I read a thread or article that detailed about 200k miles of oil analysis on a very frequently driven corvette that was a 2000 or 1999 vintage. Owner/driver was having the oil analyzed and adhering to the extended drain intervals and oil change light rather than a standard change schedule.

The short version, from my very fuzzy memory, was that you should change factory oil almost immediately. After that, go 2-3k and change again. After that, 10-15k wasn't abnormal, and oil consumption seemed to outpace wear of the oil - at least with highway miles. The oil filter tended to pick up more junk in the first half of its life than the second half, but more frequent filter only changes had so little effect on the oil analysis that waiting for the normal interval seemed fine. Once consumption went up, with mileage, and oil had to be added in less than 10k miles, the analysis showed a significant improvement in oil quality at the time of change. To the point that if an engine could take more than a quart or two between changes, you could effectively just change the filter and keep going.

Take it with a grain of salt, but those are the key take aways I remember. Seemed to make sense, and it's not for nothing that it was a fuel injected vehicle driven mostly on the highway and no track time from what I recall.
