These are great observations and good critical thinking in my opinion.not 100% sure how relevant that link s
It sounds generalized to me, otherwise I feel like data wouldve been supplied.
Reading the article I want to know
1. For point 1, is this remedied if you have dual catch cans or, are changing oil at shorter intervals?
2. for point 2, what if you have an oil cooer? is this still relevant?
3. for point 3, what if youre not racing in california lol
Consequently, articles like that, are why I don't feel like doing out all the calculations. I'll spend all this time writing out all these equations, explaining theory, then doing the calculations. Then someone will comment, "I saw this video/article and I'm going with 20W-50".
Frankly, it's sounds like advice somebody at AutoZone would give. So much of the advise in there is utter garbage and paranoia I don't even know where to start.
1. The API SN+ and SP standards (and GF-6) have testing for ethanol blends and fuel dilution.
2. The oil in the crank (and its bearings) are constantly being pushed out. That's how hydrodynamic bearings work. By this logic we should all be running gear oil in our engines.
3. Yes, viscosity does decrease with temperature. Consequently, the flow will increase, which will increasing cooling in the bearings. As I mentioned in another post (with rough calculations), increasing viscosity will result in higher temperature rise in the bearings compared to 0W-20.
