The pour point of an engine oil is readily obtained from technical specifications that are almost universally available on the manufacturer's website. I don't know of a multi-grade engine oil with a pour point above -20C (the low temperature qualification temperature for grade 20W) so your test would not be real interesting or informative. Premium conventional "summer blend" mono-grade oils have a pour point commonly ranging between -30C (SAE 30) to -10C (SAE 50).

Amsoil's -40C pour point demonstration is a contrived example using 5W30 oils and a test temperature at the absolute lowest extreme of the SAE requirements specifications (e.g. 0W). It is cherry picked to make their product look superior and it is not interesting or informative either.
