Trunnions (TR6): oil or grease?

[Cregg Cowan <cowan@erg.sri.com>]

Friendly Scions,

I've heard mention that trunnions should be oiled, not greased.  I
have mine apart now and they look real good after 80K miles on grease
(me and the DPO, you know).  Should I now switch to oil?  What weight?
The controversial Haynes TR6 manual is unclear.  I tried the VTR
maintenance handbook but couldn't find the answer.

Best Regards,
