FWIW, changing to Mr. van den Hul's zirconium oxide-doped spindle oil made all the difference in my Goldmund TT.
Supposedly the super hard zirconium oxide particles act like nano ball bearings which actually keep the metal surfaces apart from one an other, thus eliminating bearing noise. The oil itself is used more as a "vehicle" to keep the particles in suspension.
Because the zirconium oxide is so hard, I'd check with A.J. vdHul before using it in bearings with plastic components.
