Where is the thread about oil experiment on fleet?

I remember reading a thread a while ago about how a BITOGer who had a chat with a manager of a fleet that did an experiment by using different types & brands of oils on their fleet and doing UOAs for every change. The outcome was that using dino or synthetic made no difference in wear numbers but changing brands of oil increased wear. I can't seem to find this thread anymore, can anyone please help? I'm curious to see if there are any updates. Thanks
