Don't argue with the science guy.

Molecular physics is molecualr physics, whether you pull the molecules out of the ground or synthesize them in a lab or plant the behaviors are consistent. the greater polydispersity of the mineral oils make them a bit better at lower temps.
Here is an article that compares the two if you care to read it. The (petroleum based)mineral oils actually lubricate better at low temps(thicker film before parts expand). this means that its even more important for synthetics to warm them up. Yeah, I used to be a metallurgist, so I know about expanding metals.
