The poster is a member here. The UOA is on this site too I think, along with a few others that are also good. IIRC the suggested max amount of MMO is 20% sump capacity, so in a 4 qt sump a qt would put you over the suggested amount.
Good point about negative comments. I'm sure any company that mfgs a product would pull negative comments about their products, Mobil, Amsoil, Pennzoil, and others, if they had a message board. The smaller the company the faster the negative post would be yanked. At least here we can talk a little more openly.
