Regulator Grease?

[BSJ]

What kind of grease or oil do Lane/Huma use in their regulators? Is it a thick oil, or a thin grease...? :-\

The clear runny stuff in syringes, not the "divers" grease in tubs.

The stuff that when you try to squeeze out a small amount, the plunger suddenly slips right to the bottom and shoots out all of it!!!
