Seems like most on here are using Blackstone Labs? I use Schaeffer Oils and they have a free analysis program. I'm starting to wonder if I'm missing something though, as I have lots of miles on the oil on this car as well as a couple other vehicles I own.
This is for a 2005 Jetta TDI BEW engine with Supreme 9000 5w40 oil.
