What oil analysis lab do use?

Just wanting to see what UOA labs people use. I have used "Oil Analyzers" 2 times and "Oil Analysis" once. The latter gives a fancier report but lacks TBN and the report takes forever to come back. Analyzers gives the same info but in simpler format but does include TBN, time to receive report is quicker. The price is within a couple of bucks. I think I will stick to "Oil Analyzers". Any body else have some input?

Oil analyzers I think does a pretty good job. Blackstone is used by a number of folks. I think they are pretty decent too.

I have used Oil Analyzers (AMSOIL) for all my oil analysis samples. AMSOIL's lab is the best value in my mind. I have used Blackstone for my ATF analysis. I like Blackstone's report format much better. They seem to be more professional. I do worry about the TBN test from Blackstone - it's all over the map. It's also an additional $10.
