Or so I have read. They were the FIRST company to produce fully synthetic oil many years ago. Anybody use Amsoil or have any opinion on it.

I am in no way endorsing this product, this is just what I read:
Four ball wear test (ASTM D4172) 40Kg load pressure at 150° C, 1800 rpm for 1 hour
Amsoil 0W-30: 0.373 mm wear
Mobil 1 5W-30: 0.589 mm wear
Mobil 1 0W-30: 0.607 mm wear
Diminishing returns for amsoil, even if it is a little better, its probably not worth the cost. Enough high end sports cars require/recommend mobil one, while I've never seen a single one say amsoil, that I feel comfortable with it.

Who performed the test? Do they have any real world tests, or at least tests on actual engines?

I don't know, I'm still reading. Apparently, Amsoil is a much smaller company than Mobil and they don't want to fork the millions of dollars in a controlled test. And Mobil won't do it, because they know Amsoil is a better synthetic.

Well, the test you posted was highly unrealistic. At those rates of wear, the bearings in any real engine would be completely gone after 500 miles.
I didn't post it, somebody else did. I just reposted it. I'm not endorsing it. Just seeing if anybody uses it, etc.

Amsoil formulated and marketed the first "API classified" synthetic motor oil. Amsoil was not the first to formulate or even market synthetic lubricants.Or so I have read. They were the FIRST company to produce fully synthetic oil many years ago. They'll even test your used oil to see how your engine is wearing! Anybody use Amsoil or have any opinion on it.
