every base oil is vulnerable to oxidation which is more easy to occur in the presence of water, salts, pressure, heat. what i mean by heat is not boiling temperatures but sudden, short, localized increases in temperature.
Water doesn’t oxidize oil. Water doesn’t “oxidize” anything. Water is mostly in reactive. Salts...of just about any kind...are neutral to petroleum based oils. They don’t disassociate in oil nor would they have much effect if they are dissolved in water. Vegetable oils are much more reactive than petroleum based oils...more olefinic groups...and they don’t oxidize easily in foods even when in contact with salt and acid.
The chloride ion in some salts can oxidize steel but they have no effect on the nonpolar oils.
The kinds of temperature temperatures a bicycle chain experiences are tiny even if highly localized. Compared to the kind of heat experienced in internal combustion engines, it is essentially nonexistent. It will have zero effect on the oil.
one of the reasons gear oil is flowing in car's transmission for example is to transfer heat away from where it gets produced and that is friction. so i explained the main reason the hBN additive shines when it comes to solid lubricants.
And completely not applicable to bicycles.
in a solid lubricant environment you will have friction that is not dissipated by the metal which does NOT contact metal. what you might call a small bit of temperature increase is a detrimental factor that is not to be taken separately but contributes to the likeliness and speed of lubricant degradation in time. it can also make the wax move away due to having a not so negligible thermal expansion.
The kinds of friction you are talking about won’t matter. The magnitude is too small to matter. Any lubrication on a chain is also not going to be on there for all that long anyway. The amount of time needed to oxidize oil at ambient temperatures is so long that the lubricant is going to be contaminated or replaced long before it has a chance to oxidize.
what people that are interested in using wax should take from what i wrote is that wax is a crappy lubricant if the needed additives are not there. i explained why, you seem to not have had the patience of reading that part which helps people get convinced to get a homebrew and not just some candle wax etc. and remember the whole bits when it comes to practice. maybe i should not explain too much, let marketing do it's thing, let people stick to brand lubes and never try some homebrew...
Additives are just not necessary. Not for this application and certainly not enough of a issue to address what you seem to think is at hand.
another erroneous thing on YOUR part... quote:
“Petroleum”, “candle”, and “paraffin” are all synonyms for the same thing.
they are not the same thing. ever heard of Microcrystalline wax
Candle wax is generally microcrystalline wax. Yes, there are probably slight differences but they aren’t as great as you seem to think they are.
forget about imputing the lack of capitals on my part, it's the content that really matters, not the lack of capitals. i never insert capitals at the start of the sentence for that reason. and i hate putting effort in some post on the interwebs and then having someone else accusing me of "misinformation" (which is a false accusation) and on top of that... the lack of capitals. next thing will be the occasional grammatical mistakes, right?
rly?

The lack of capitals makes reading your posts difficult. You effectively have a run on sentence where we don’t know the beginning and end of your thoughts. Presentation helps clarify what you are trying to say.
