Marty,
That 30 year old tub of grease is probably WAY past it's prime.
Grease has a shelf life! Estimates of how long grease remains good
vary, and synthetics probably last longer than mineral-based greases,
but five years is a common spec for grease stored in an *unopened*
container. See, for example:
http://www.finalube.com/reference_material/Grease_Shelf_Life.htm
https://www.fammllc.com/famm/publications/lubes_bulletins_01.pdf
A container that has been opened and closed many times over the years
has allowed much more contact with air. You aren't doing your
bearings any favors by using grease that's had that much time to
oxidize. It's better to buy grease in small tubes, and use it fresh.
I'm converting our maintenance department at work to using grease
cartridges instead of bulk grease (except for the few applications
where we can actually use a drum within a couple of years) for exactly
that reason.
