In the 8V Failure Info thread, I suggested that for anyone concerned about premature valvetrain wear, perhaps changing the oil at 3,000 or 4,000 miles (and adding a ZDDP additive), instead of waiting to 6,000 miles, was a good idea. For reference purposes, I cited a White Paper on the subject of extended oil changes that I received from an engineer with whom I have been corresponding.
I should have known that this modest proposal would get that thread sidetracked on the issue of the value of extended oil change intervals. By "extended oil change intervals," I mean, generally, intervals longer than the "3,000 miles or six months" that was typically recommended by most engine manufacturers until a few years ago. In an effort to keep the 8V Failure Info thread on track, I'm starting this thread for anyone who wants to discuss the issue of extended oil changes.
The proposition, as argued by an engineer (not me), is that even with today's better-made engines and synthetic oils, the old 3,000 mile oil change interval is still a good rule of thumb, if you are concerned about minimizing engine wear.
Several posters quickly challenged that notion. So, is changing oil at 3,000 miles a good idea, or a waste of money and resources?
For anyone interested in reading the Paper I was referring to, i have uploaded it to Google Documents, and you can view it by clicking here:

Have at it!
