What oil for VPI HW19 turntable?


Using a VPI HW19 table and figure it's time for a oil change.
here are the questions. How often should or do you change the oil? And, what oil to use?

Mobil 1 is a good choice, as this brand is a true synthetic oil (a liquid paraffin as opposed to 'reconstituted dino juice' that masquerades as synthetic). Either will vastly outperform the level of performance required to lubricate a turntable bearing.

Regarding the Annie Hall reference, Woody (Alvy Singer) pulled Marshall McLuhan into the scene at a theater ticket line to verbally castrate a pompous university professor. Here it is, a great moment in cinema! Enjoy.

Alvy Singer: (a man behind him in line is talking loudly) What I wouldn't give for a large sock with horse manure in it!
Alvy Singer: (to audience) Whaddya do when you get stuck in a movie line with a guy like this behind you?
Man in Theatre Line: Wait a minute, why can't I give my opinion? It's a free country!
Alvy Singer: He can give it... do you have to give it so loud? I mean, aren't you ashamed to pontificate like that? And the funny part of it is, Marshall McLuhan, you don't know anything about Marshall McLuhan!
Man in Theatre Line: Oh, really? Well, it just so happens I teach a class at Columbia called "TV, Media and Culture." So I think my insights into Mr. McLuhan, well, have a great deal of validity!
Alvy Singer: Oh, do ya? Well, that's funny, because I happen to have Mr. McLuhan right here, so, so, yeah, just let me...
(pulls McLuhan out from behind a nearby poster)
Alvy Singer: come over here for a second... tell him!
Marshall McLuhan: I heard what you were saying! You know nothing of my work! You mean my whole fallacy is wrong. How you got to teach a course in anything is totally amazing!
Alvy Singer (to audience): Boy, if life were only like this!
