We all come from different backgrounds and have different expectations because of the environments we've been exposed to. I cut my teeth in very technical forums where you were flamed for not searching, not reading and asking the same questions that have been asked dozens of times. One of those was actually a car forum for the Acura Integra. Even the mods would tell you to search or you'd get banned.
Perhaps we could meet face-to-face one day and have a beer or three (after racing our VTs at Streets of Willow or wherever). I'm not as much of a dickhead as I convey here.
As I said, I'm an analyst and a scientist at the core. I'd love to be able to do testing that shows how lubrication is much more complicated that what is commonly known.
At the end of the day, I'm just an enthusiast that leans more towards science and outside-the-box thinking instead of accepting the common norms.
Look at some SAE articles that go way back to the early 20th century. Fascinating stuff, even just looking at the previews. We haven't progressed as much as we should have as far as the internal combustion engine goes.
I'll tell you what I will do. If I have any problems with any engine I have due to running much thinner grades of oil than spec'd, I'll post somewhere here about it and attempt to determine the exact cause.
Until you're willing to try CERMA treatments and thinner grades of oil just as experimentation, willing to risk your engine, you're truly missing out on some things that can give you an advantage that can help reduce lap times. I'll even give you some for free. Put it in a beater car.
