With all else being equal, will a higher viscosity oil provide a stronger hydrodynamic film?
For instance, in a high lift cam application, where the oil film is prone to be breached momentarily, will the thicker oil be less likely to allow metal to metal contact?
I realize that too thick of an oil will cause problems elsewhere in the engine... but setting all that aside, does the heavier oil have the better hydronamic film?
