Short PSA:

WD-40 is not a lubricant. It is a brand of penetrating oil, also known as penetrating fluid. If you have metal parts that are rusted solid, WD-40 might help you get them to move so you can take them apart, but it evaporates quickly and leaves no lubrication behind.

So if you want to *oil* something, you need a lubricating oil. Which one depends, but which one is never WD-40.

@packbat for lubricating oils, silicone oil and lithium grease are two of the best for general-purpose long-term use. neither significantly degrades or evaporates over time, and they're both compatible with most plastics (this is something to keep in mind: plenty of lubricants can dissolve plastics)

@Felthry
Please be careful with lithium grease and potential skin contact. There are many white greases that are free of lithium soaps.
