yeah me too, i get pretty nerdy about it. there are some opinions about how useful some of the wear metal readings can be due to accuracy disputes and oil characteristics but one of the most important things i get out of it are the CST/SUS viscosity numbers and the TBN reading. that stuff tells you how hardy the oil is under use and how much additive remains in the oil so you can figure out how long to run it. in these days of $10/qt oils i want to run that stuff as long as possible and this is a good tool to figure out how to do it safely. plus it sucks to drain out perfectly good oil from a waste standpoint.

i've got Rotella T6 5W-40 in there now and i'm going to try to run it out to 8,000 miles and see how it looks.
