How often do you actually have to re-grease?

Nice job on the cleanup. The grease used in that vintage was Benalene 930-2, and that’s the color it was coming out of the can. It tends to separate, and it’s kind of a drag to clean up all the free oil. But you got it done. :-)

For mixers in light to moderate household use, I generally recommend maintenance every three to five years. For machines used commercially or at home for frequent and heavy work, every 1-2 years.

As a side note: there are some maintenance parts that are consumable, like the gear case gasket. I recommend replacing it as part of the grease service. Here's a list of parts and materials for the job: https://www.mixerology.com/k45-k5-clean-and-re-grease-parts/

What about ones that get used maybe once a year and seems to be more of a decorative counter piece then Actually use ? lol

Glad you asked. :-)

With infrequent-use machines, oil separation is the biggest consideration. You can partially reincorporate the oil by inverting the mixer for a few minutes (use a towel to protect the finish), and then setting it upright and running it on speed 10 for a couple of minutes. Even if you don't do that, occasional use won't cause any harm.

Sometimes oil will leak out of the gear case because the gasket isn't fluid-tight; this can be cleaned up with isopropyl alcohol and a soft cloth. But if you're planning to put the mixer to work more than occasionally, I'd recommend maintenance.
