Interesting. Everybody has always associated this lab with Amsoil. I know that Amsoil now uses Oil Analyzers Inc., but if you look, the sites are very similar and if you log into OAI's site, the addess says something about "amsoil.ctclink". If they aren't the same lab, the are related somehow. I'm glad that this lab is finally associating itself with another manufacturer (other than Amsoil). This way people won't be able to say that they are making Amsoil look good and the the competing oils look bad. I have used this lab due to price (less than $15 plus $1.52 postage for Amsoil preferred customers) and will continue to use it because of the differences between labs.
