[QB] 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, especially given the fact you'd be swtiching tests to the CCS and MRV tests at cold temps.
