And as for "chain suck", we really must stop using this misleading term.
Why misleading, the chain gets "sucked" back onto the chainring by the hook like worn teeth. I think it is a good image.

It misleads people into thinking that the underlying mechanism is suction. We can't have that.
Suction: the act of removing air from a space resulting in a lower pressure in that space, either causing liquid, gases, or other substances to enter, or causing two surfaces to stick together: https://dictionary.cambridge.org/dictionary/english/suction
"Chain slap" is another one. I think this probably Ok.

I recommended the use of "parts". This avoids "separated" which could easily imply deliberate action, and is more useful than "breaks" because it describes the effect of failure.if your chain separates or breaks under tension is it permissible to use the term "snapped"

I still can't believe that there are people out there who take shortcuts with chain maintenance. Do it properly!

When I do "lubricate" a chain, I do so with car motor oil that I found along street / on public place, dumped there by magnificent people that came from other places in the world.Over 100 miles in to my first use of Fenwicks Professional……

The drive train noise (Or lack of it) is barely any different to when it was originally applied, mess is right around zero. Colour of chain / sprockets looks good / clean 👍
My first impressions are very-very good. There may well be better. But I’m pretty sure - even after this short initial test - this is the best I’ve used to date.
The smell took longer to go, though.The thing is, after that professional removal of all the dirt, the chain will have become longer under tension, since the dirt between the mating surfaces, prevented it.Sheldon is/was such an amateur. Any true professional would matchmark their chain components to ensure that they were re-assembled correctly.
