VPI bearing oil/grease?

Slaw, thanks for the update. Not entirely clear what your final assessment is. I agree that different lubes all have slightly different tonal signatures in any given tt; best in this case is clearly system dependent. What is not so system dependent, and my main issue with the thicker the oil/grease, was that the thicker the lube the less lively and speed stable the tt's sound was. Did you arrive at any conclusions regarding this?

Frogman/Slaw,
If you can, try and get some Motul V300 Power Racing, either 0W30 or 5W40.
It is simply the best synthetic oil on the planet, a double ester synthetic, using extract from Copra. It is highly unctuous, which means a film will adhere to non moving parts and very slippery. Mobil 1 is like sandpaper in comparison. Most of the race cars with Mobil 1 stickers on them are not usually using it. I have tried various, molybdenum sulphates, laboratory grade oils, etc on TT's ranging from Linn/Oracle/Roksan/Townsend and many others. On the Roksan which has a very fine bearing, the 0W30 worked well. On my Final Audio ( 22kg platter/inverted bearing ) I use the 5W40. Unless the bearing is low tolerance for conventional non inverted bearings the 0W30 is fine.
In my experience some of the teflon based products and lower grade oils increase wear markedly.

Thanks, Dover I will look into the Motul; it's getting to be time for my annual bearing cleaning and relubing.

Along similar lines, what do project owners use for lubing the spindle?

Frogman: Yes, the heavier, thicker lube makes for a less lively, thicker, muddy, uninvolving sound that makes listening a chore.

Dover: Thanks for the Motul suggestion, I remember now, hearing guys involved in motorcyle racing mentioning this oil.
