For anyone suffering from insomnia, I ran across this massive report about Motor Oil Engineering Test Data:
https://540ratblog.wordpress.com/From the blog:
"The motor oil wear protection test data included in this Blog, is from Engineering performance testing of many different motor oils, which shows how they compare relative to each other. The focus is on the motor oils themselves. Therefore, the resulting comparison data applies to ANY engine that uses the oils included here, no matter if the engine is used for racing, daily driving, grocery getting, watercraft, or any other activity.
"I operate this Blog in my spare time when I get the chance. I simply share my Engineering Test Data as a courtesy to other Gear Heads. I do not express an “opinion” about motor oil like most everyone else on the Internet does. I do not express a “theory” about motor oil like most everyone else on the Internet does. I merely post the FACTS that the Science of Physics and Chemistry proves to me. And my test data EXACTLY MATCHES real world experience. A number of examples are provided below in this Blog."
