Manufacturers Specs
This is a very interesting question. . and one I don't have an answer for, but maybe the answer would put to rest alot of the bickering going on here on TDR. I know my last post was long-winded, and I appologize,but as before since I have some of the products in question in front of me, and feel I am nuetral in the debate, I will post what it is printed on the back of the bottle of
Series 3000 5W-30 HD Diesel Motor Oil... since this is probably of most interest. Here goes:

If anyone knows if Amsoil gets their oils tested by the manufacturers or if #'s above mean they've met or exceeded the manufacturers specs for thier recommended oils, jump in and show us some data. Thanks Ed3
