Not saying that makes the Amsoil bad at all, but don't think that would have happened if it were primarily PAO...
I'm struggling to see the relevence of testing a whole bunch of 5W oils at temperatures that are the realm of (readily available) 0W oils.
Need -40 ? Use a 0W...that's where they are rated at.
The test could just have easily been which oil is closest in colour to blue, which one smelled more synthetic.
Yeah, probably not a test I would have designed either. I only mentioned it as a data point with regard to what base stocks might have been used.
It is true that primarily PAO oils (even 5w30) have had excellent pour points (south of -40F) historically, correct?
