60 below? So we can't pour the stuff on Uranus?Dunno why someone would think that but it’s definitely untrue. Group IV/V blends like Red Line are superior in cold flow. Some data to look at:
CCS (cold cranking simulator) viscosity:
RL 5800cP @ -35c
PUP 5850cP @ -35c
Pour point:
Red Line -60c
PUP -51c
So if it dips below -60 just stay home and you’ll be okay…
