What oil for VPI HW19 turntable?

Why do you figure a need for an oil change?

One changes oil in a car because of the very high temperatures that break down the oil. Dirt from road use and combustion byproducts can contaminate the oil, and slow leaks and the combustion process can cause the oil level to drop below the needed amount.

None of these things are really true in a turntable situation. The primary issue there is the oil is so old that its viscosity has changed due to evaporation of the volatile components.

If you can disassemble the component, you might wipe it off with a clean cloth prior to re-oiling.

In that case, it is not really an issue of "changing" the oil as adding some more. A light machine oil is likely the proper one to use, but only the manufacturer can tell you for sure what is recommended.

Actually, if what's in there is original, or someone else' idea, you should change it.

Remove the platter from the bearing well being caerful not to lose the ball. Unscrew the cap at the bottom of the well. Use mineral spirits on a lint free cloth like Handi-Wipes to clean out what is probably dark thick gunk.

Drip 5 drops of Mobil One 10W-40 on the spindle shaft and 3 more drops in the well. Rotate a few times, watch for spillage. Done.

That's what VPI recommends in the MK IV Manual.

Thank you.
