For some time, I have sensed an apparent/possible animosity between a few contributors to this thread and whoever it is that has the tech facts not myths web blog. If that is the case, then I will make myself very clear. Please do not draw me into any personal or professional issues between any such parties anywhere. I simply use various internet sources in my attempt to become more educated on any given topic, in this case motor oil for my own personal use. I hope to give all sources equal consideration and opportunity to prove validity of their data, rather than just opinions and biases.
It would be great it we had several independent sources from which to study and review the results of off-the-shelf motor oil quality and durability tests. And especially as it pertains to actual measurable repeatably provable film strength, since that seems to be almost like a hidden characteristic. -does the motor oil manufacturing industry classify it as proprietary information? To this date, I have found only that one source. It is apparent to me that he, (I assume) from the perspective of a mechanical engineer, became quite obsessed about 8 years ago with implementing or developing a legitimate method of testing and comparing. I know absolutely nothing more about it than what is documented on that blog.
I am just an ordinary consumer with no connections to anyone anywhere in any way shape or form associated with the motor oil industry. Several years ago, I became personally very interested in trying to compare various brands, grades, and qualities of commonly available motor oil. I very much enjoy the respectful replies and outstanding information and links to even more information that is being shared on this forum and others.
I hope that states my position respectfully, clearly, and accurately. Thank You.
