I bought LS Bell Hammer Grease 0 and 2, but the specs seem similar. Could you explain the difference and recommend how to use each? I currently use it for spiral miter gears under heavy load.

I purchased LS Bell Hammer Grease 0 and 2.
When I check the properties table, I don't see any significant difference.
Please let us know how we should use the two different types.
My current use is to lubricate spiral miter gears that are under extreme loads.
