Technically, WD40 is not a lubricant at all. It does penetrate, and if lube is there (like a door hinge with dried up grease) it will penetrate and then get the already-there grease to re-lube! Was not allowed even in the building when I worked at Rubbermaid, because it would wash away any lube the machines had on their ways.
Correct, since it's mostly Naphtha, WD40 is a solvent. I believe it does, have some 5w oil, but its not a good lube. I do use it to clean a roller chain before lubing and I do use it directly on O and X ring chains. It's also great for removing stickers.
