I use Blackstone. I buy in bulk of 6 tests. Runs about $21 per test this way. I also do UOA's on my transmission/gear lube.

I would not suggest sending them a sample from your most recent drain, because it is probably contaminated from whatever you drained it into, unless you took this into account, prior. Maybe your next oil change.

Lastly, one test won't tell you much. So, if you start doing them, continue doing them to see the data and direction your engine and oil choices are taken.
