The home page of this very website (BITOG) has a fine review of motor oils written by Molakule. If you want to do a deeper dive into motor oils, go to the right column of the home page, look for "Motor Oil University". If you wish to dive in even deeper, you can go to forums, look for the forum category called science and look for "white papers and interesting articles.
I imagine that you will find everything that you want to find and more on BITOG. This is a content rich website.
BITOG has become a great place for me to find information. I am having a great time looking through the tools forum to try and find Snap On quality tools at Craftman prices.
I hope this helps?
