Has anyone read this guy's entire website including "Motor Oil University"? I did and it was very interesting. It almost seems as all oil should be 0W-XX. Does anyone here run 0W-30?

I understand that many here run 0W-40 Mobil 1, I have been a devoted Amsoil user in my bikes and cars for years. Now I am learning and questioning why there are so few Amsoil users here. I saw 5Qt jugs of 0W-40 M1 at Auto Zone for $37.99 and a Purolator Classic Filter for $22.99. Is this the recommended formula? Even though the oil seems clean, I do not know what it is and I would love to see and examine the filter for reference and for monitoring. I expect to be changing my oil in March and August of each year, same as I do for my bike.
