I don't know if this helps or not, but I used to own a 95 Saturn SC1. I put Mobil 1 oil in it at one of the oil changes, and shortly later it developed a similair condition. The only difference between the video's sound clip and mine is that my knocking went away at about 2000 rpms. I didn't own the car long enough to take it apart and fix (plus it was a POS anyway) cause it got impounded. I had talked to a mechanic briefly about it and he said that the Mobil 1 oil tends to seperate itself when put into engines that haven't used it since the beginning. He didn't tell me why this happens though...

Anyway, I don't really have any advice on how to resolve it, but all I know is it doesn't sound like rod knock (or at least what I've heard from before my Supra's engine blew).
