You see where I am going with this. Form your own conclusions.

Seems like you guys are trying to say something. If we only had this level of fortitude and balance with the pop oils.
There's an existing thread here:

Which begins to address the validity of the ASTM D-6278 test.
Also we have:

I don't have the spec on this computer, but I'll read the whole thing on Monday.
It's a single lab test. Again, as I say about all tests, including the 4-ball test. It's a single bench test. No more no less. Schaeffer's uses it, other GOOD oil companies use the test. It's referenced here:
http://www.astm.org/Standards/D4485.htm
As for the 2001 Orinite presentation, I'm not sure whatever became of that but ASTM D-6278 has gone through two revisions since then, and the seems to be more widely adopted since then. I see some errors in the paper as well. Just because it's from Chevron doesn't mean it's not biased (you guys can spot bias, right?)
And of course ads for a product are supposed to say a product is awesome. Why would we think otherwise?
And yes Amsoil is sold in many stores, but what the heck does that have to do with this thread?
