So I tried to search around to find an answer to this, but I'm still puzzled.
I understand that most automotive greases use lithium as a thickener (i.e. the soap which keeps whatever oil the grease has as its base). From what I can gather, the only difference with 'WHITE lithium grease' is that it has zinc-oxide added to it - but why? I've seen a few sources say that it's just for seeing where the grease got applied or whether it's contaminated (so purely visual benefits). Is this true?
When would you use white lithium grease over something else?
I had no idea that lithium grease wasn't naturally white.
I can't remember what problem I was trying to solve, but a guy at Home Depot who had worked in automobile assembly recommended white lithium grease and it worked great.
I only use the stuff when there is next to zero chance of anybody touching it after it has been applied as it is so hard to get off one's hands (or clothes!)...I would also assume it's not meant to be exposed to extreme heat.
I do appreciate how tenaciously white lithium grease holds on to surfaces for the right applications...
