message: "Some rendered animal fats are known as greases. Rendered chicken fat becomes the commodity known as yellow grease. Animal greases may have been used 
as lubricants in the past, but this is not now common in developed nations."
Every dictionary I've looked in has animal fat as the first definition of grease, and it seems to be the etymology of the word.  Wikipedia isn't a dictionary, but is it odd to devote the entire article to what is technically a secondary meaning of the word?

message: Isn't grease also applied to prevent rusting (by keeping water off/out)? Rvollmert 11:39, 2004 Jul 31 (UTC)
It can be, but that is a secondary effect--generally you only have exposed, unpainted metals if you have external moving parts, like bike chains.  Some greases are not water resistant, it depends on the type of emulsifier used.  Since the emulsifiers tend to be soaps, if they do dissolve in water, they can actually help to remove the residual oils...  Heavier oils are more often used as a protectant for non-painted metal surfaces (like blued steel in firearms), but they tend to rub off, thus losing their protective abilities and likely staining surfaces they contact.  Greases can be used, but suffer the same disadvantages as oils.  Waxes are my own preferred treatment for firearms, since wax isn't as slippery (don't want to drop a loaded gun) and it doesn't rub off.  There is a company that I ran across that sells a mix of soap base, wax, and dry lubricant--sort of a solid EP grease--that they promote for use with bike chains.  The solid nature of the final product keeps it from collecting dust and grit, and turning into what is effectively a grinding compound.  scot 17:26, 22 Dec 2004 (UTC)

message: This statement:  "Grease-lubricated bearings have greater frictional characteristics at the beginning of operation, causing a temperature rise which tends to melt the grease and give the effect of an oil-lubricated bearing" seems to contradict this one:  "Lithium based grease has a drip temperature at 350° to 400°F".  If friction induced temperature rise is the root cause of the shear thinning effects of grease, then it would have to run at >400F to lubricate well, which is obviously not the case for oil/soap greases, thought it may apply to petroleum jelly and similar room temp solid oils.  I'm going to take out the bit about temperature rise causing the thinning, since it obviously doesn't apply to most greases.  The actual mechanism has, I beleive, something to do with the polar/nonpolar mix, and pseudo-crystalline arrangesments formed when the fluid is at rest. scot 18:26, 12 August 2005 (UTC)

message: I've just come across something called 'copper grease', which apparently has anti-seizing properties. Like this:

If anyone knows anything about what it is and how it works, i'd be very interested to read about it.

message: "the reduction of shear force with time makes it thixotropic."
Should that be reduction in shear strength?

message: At a store near me there are containers of grease for sale, all apparently intended for use in automobiles, of the same brand name from the same manufacturer.
At the lowest price level is a yellowish translucent grease, marked "lithium grease."
Slightly more expensive is jet-black "lithium moly high pressure grease," which I assume contains a certain quantity of powdered molybdenum disulfide.
Most expensive is a bright red translucent substance, labeled "multi duty complex, high pressure, high temperature grease."
What do these terms mean in this context, and how is its composition likely to differ from the others?  —Preceding unsigned comment added by 192.148.105.4 (talk) 20:51, 19 July 2009 (UTC)
replies: text: If it's Wal-Mart, you can look up their MSDS pages online.  Mind you, they're not always very enlightening.  Half the greases and lubricant products seem to be listed as "ingredients:  proprietary additives"  Which does not answer your question, I know.  —Preceding unsigned comment added by 98.224.244.181 (talk) 01:38, 21 July 2009 (UTC)

thread_title:  What is "Grease OG-2 (PC Red)" 

message: The first sentence of section Properties, says "A true grease consists of an oil and/or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid." The third sentence says that "greases are a type of [...] fluid."
Either something is a solid or a fluid, no?
I am guessing there should be some other word than "solid" in the first sentence. Stephanwehner (talk) 05:52, 16 August 2011 (UTC)

message: Isn't aluminum stearate also used as a grease thickening agent?  I am given to understand, though I am no expert on the topic, that aluminum-based greases are chiefly dyed dark blue for identification and used in marine applications due to their higher water resistance.  Is this the case?  — Preceding unsigned comment added by 73.190.21.154 (talk) 20:56, 22 March 2015 (UTC)

message: The "Lithium Soap" article (section "Lithium Grease") says that Lithium Grease is water resistant, 
The "Lubricating Grease" article (section "Engineering assessment and analysis of greases") says it is not.
Please would someone knowledgeable correct (at least one) of these ?   Many thanks ! Darkman101 (talk) 19:17, 16 February 2017 (UTC)
