    it has to because the oil sits in the sump,oil does not defy gravity

    Not all the oil sits in the sump. The galleries etc. are normally still relatively full.
    It won't climb up your bearing either.

    The point is that engine oil works best in a pressurised environment, which your bearing isn't.

    Typically I can't find it now, but there is a thread 'out there, on't internet' where OP catalogues all the turntables and oils they use (+ often in relation to which engine/gearbox oil will work as per that supplied in the deck originally) I'll keep looking.

    It is to an extent. There is no bearing that runs exactly concentrically, meaning that small localised 'waves' of pressure will be created in the lubricant as parts rotate.

    Is there no pressure in a turntable bearing?

    The oil in a combustion engine has multiple functions, lubrication, cooling and as cushioning film against the hammering effect of the explosions in the combustion chamber that is transferred by accompanying metal components. Not a complete list of functions by any means, but it will do for now.

    To say engine oil works best in it's designed environment may be true, but that doesn't proclude other uses.

    When will we get to the viscosity of multigrade oils at room temperature bit....

    You could go into ageing characteristics and oxidation effects too while you're at it.
