Not significantly different in doing an oil change on the older bearing and the newer inverted bearing (I've owned my Gyrodec since 1985 so have done multiple changes on both types of bearings) but the old style bearing would not be usable immediately following a change and would need at least a few hours to settle and seat properly.
With respect to oil, I've used Mobil 1 0W-40, Amsoil 0W-40 and the Audio Origami oil over the years, switching to the Audio Origami oil in the past few years. Anecdotally/subjectively, the Audio Origami oil is superior IMO in terms of sound quality; improvements are slight but they are there. The ceramic ball bearing makes a much bigger improvement in sound quality.
The Audio Origami oil is unquestionably a better lubricant though and much better at reducing friction in the bearing; the platter spins more freely and easily than with any other oil I've used. Worth the extra money IMO.
