What viscosity is this particular oil?

Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90For heavily-loaded racing differentials and transmissions, problem gearboxesMany performance racing applications like Sprint/Midget/Dirt Late Model Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear endsNot recommended for most synchro applications due to the product's extreme slipperiness

What is the viscosity of this? Need a specific number.

Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90. This is from the manufacturer's site.

Canged primary chain OIL of my 2002 RoadKing ScreamingEagle I made a MISTAKE! Added REDLINTransFluidw/Shockproof. IS It COMPATABLE

I would think not. As the primary runs a 20w 50 and the red line is something like 75 90 it's going to a lot thicker. I would call a local Indy not HD and ask them for sure.
