Actually, they are a LOT of labs across the US. Probably each major metropolitan area has a few local ones as well. I've been using Blackstone for a long time and they are the 1st one I recommend to peoiple new to this sort of thing.

I've also used Titan Labs ... but was less impressed with them.

Schaeffer Oil does their own analysis ... as well as OAI (Oil Analyzers Inc) ... but they are affiliated with Amsoil. Call me paranoid but I'd prefer to use an unbiased, 3rd-party lab.

However, I strongly recommend everyone pay the extra $5-10 for Terry Dyson's interpretation of the lab results. This is especially true if you've never looked at one of these reports before.

Let me know if you can't get a hold of him (contact info in BITOG's sponsor section).
