Lube for turntable - What do you prefer?

It depends on the table, actually on the bearing to be more precise. What works in one bearing could be a disaster in another.

If your bearing was designed to use grease, then grease is what you should use. Bearings designed for grease typically have large tolerances between surfaces. Using a much thinner, lighter lubricant like machine oil will allow play, which will increase surface wear and shorten component life.

OTOH, a bearing designed for lighter grade oils would have very tight tolerances. Packing that with grease, if possible at all, would make the bearing virtually immobile.

Stick to what the TT manufacturer recommends.

In that case he should know the answer!

It depends, as I said, on the tolerances of the bearing and also on the materials inside the bearing.

With that information a mechanical engineer with lubrications expertise could make a recommendation based on real knowledge. Recommendations from audiophiles who use different tables would be useless, and I've already posted many useless things here! ;-)
