By the way, when I'm rich, I'm going to buy up every oil filter on the market and send it to these guys to test. I'll need to win the lottery first, I heard it costs about $1000 per filter for their testing!
Several of these testing labs turned up when I was looking for J806 info last month. Wish I still had sabbaticals. An internship could be very educational.
These SWRI guys are not too quick at answering emails. I sent emails to two different guys asking how to obtain their electronic articles, and have not gotten a response back yet.
