OIL OIL LAB TESTING What does it all mean??

http://speedtalk.com/forum/viewtopic.php?f=1&t=35731

Another thread with what appears to be diligent testing of oil. And then a number of people pointing out issues with the results.

This is pretty great info thread you have going here. I have lately seen a bunch of info about "poisoning" oil by adding zddp additive to it. Ahhh, what to do?! I have dosed all my flat tappet engines with a quarter bottle of lucas zddp and can't friggin decide if I should omit on the next oil change.

edit, after more reading, I think I am going to just have the oil analyzed on all my machines that I care about after 3K or so of running.
