All the discussion here about the TBN of motor oil and you think it's "acidic"? What a waste of time.
I cannot think up an example, but I "thought" I had wiped some tools down with it and it 'etched' the metal or something. Or maybe used it on a bicycle chain, or some other metal parts and it left it being 'less pretty'. So, I say, if I need to reword it, PCMO is not a good all around general purpose oil. It is made specific to run in engines. While it may seem that " since it is good enough for engines it should be plenty extra good for anything else". How is that?
Kind of the, if some is good, then more must most certainly be better line of thinking/deducing.
