UOA and viscosity

[metroplex]

Can they determine viscosity at -10F to -5F, 40C, and 100C for UOAs? It seems to me all they list for the majority of UOAs is the 100C viscosity.

I know the lab Patman uses, Wearcheck I beleive, will do viscosity @40 C if asked. Blackstone's reports also offer a blank for this information, so I'd assume tey can also do it if asked. As for testing at -10 to -5F, I'm doubtful any of our regular UOA companies would offer that service, as that is not a "standard" testing point for viscosity.
