Grease is made of three primary parts, Base oil, Thickener, and AdditivesCheap grease is in reality nothing but clay.
Under heat clay dries and goes hard.
Either grease daily (keeps the zerk open) or upgrade to a synthetic grease.
The clay based greases are in all practical purposes very effective but in this day and age there is much better.
Base oil can be Mineral, Vegetable, or Synthetic
Thickeners can be Calcium, Aluminum, Lithium, Barium, Bentone (Clay), and others
So it is entirely possible that a synthetic grease is clay based
Bentine clay has been used just about forever and makes a very good grease. In some applications it is the best, in some it is not. It does not make it a 'cheap' grease.
