oil change t/t

All oils are not the same. You should check with the manufacturer to see what is best for your table. The 3 in 1 multi purpose oil is explicitly identified as something I should not use in my turntable. Some manufacturers, like Linn, have their own oil mix, just like Honda cars do.

Ask them how to clean the well/stacked ball bearings and what type/quantity of oil to use.

You will need to clean the well, and clean/inspect the ball bearings anyway (might as well do it right the first time).

Regardless of what I've read online I would never use automotive oil in a TT bearing and as mentioned 3 in 1 is not suitable (I avoid multi-purpose oil in general).

Dekay, why would you not use a good synthetic motor oil for your tt bearing?

Because one if the automotive oils being hyped for TT use destroyed a low mileage/excellent condition Citroen engine (per my Citroen trained mechanic).

The oil manufacturer eventually admitted their product was not suitable for the engine, though you would not know this from their ad/spec copy.

Nothing special (;-) about the engine other than it being of 1960's design.

Better safe than sorry is why I avoid automotive and multi-purpose oils.

I use Singer "sewing" machine oil in Thorens decks (have since the early 1970's), but the SY TT bearing is different/unique with its stacked ball bearings.

Hypoid, 80w/ 90w transmission oil.
That's what Rega used some say.
