Stuart, I've heard that synthetic oils are poorer conductors of heat than conventional (dino) oils. If this is true, couldn't the operating temperatures actually increase with Red Line synthetic oil? I have a similar concern with using a synthetic gear oil in my syncro's front differential. The differential is bolted directly to the Viscous Coupling housing. If the heat, instead of dissipating through the differential housing, migrates to the VC then I have a problem. The VC is VERY sensitive to temperatures and will tend to engage prematurely if hot. Can any List member confirm/refute the heat conductivity characteristics of synthetics? Any specific recommendations on where/when to use it?
