Everyone has a magic answer to this question. But first you might consult Origin Live. They presumably know what are the needs of whatever bearing they use in their turntables. KAB does have, or claims to have, the correct original oil for Technics DD bearings. On the other hand, single-weight, non-detergent motor oils work, too. I think I use 0-20W in both my Kenwood L07D and my Victor TT101, but I would need to check (at home) to be sure. You can also buy very high quality machine oil in most good hardware stores. Just avoid oil made for cars that contains detergents of any kind.
