So not a 15 micron ABSOLUTE as you said earlier.
That's a good filter, but now I am at the part that turns me off to Amsoil.
And I think if you do it once, you'll do it again. (not you specifically, a global you)
why claim an absurd 15 micron absolute rating when you have data that says a perfectly fine B75 at 15?
Why rely on a cheap screening test, 4 ball, as a basis for suitability when you have ngine run data that says it is better than some or even most?
My opinion, cherry picking to get tho the top of amsoils cherry picked list of attrtibutes.
At these levels of hyperbole and obfuscation, I have to wonder what is missed bu those without all of the raw data.
