Can't seem to find too much info, back a few years I bought an Oilguard system along with a case of oil sample kits. (prepaid)

The filter still works great but would love to know where the company went to.

 

Sent the new company folks an email regarding the testing service just to see if they reply. From what I heard it used to be a father/son operation and they had /have a great product. But it looks like the site has changed a bunch.
