WD40 is absolutely a lubricant. The WD40 is not a lubricant thing just needs to die already. Of course it’s not the best lubricant for every job. In fact it’s probably not the best lubricant for any job, but it’s a good enough lubricant for many jobs. It’s also a penetrant and water displacer. Versatile products usually aren’t the absolute best choice for a given use case, but that doesn’t make versatility bad.

From Wikipedia:

> WD-40 is an American brand and the trademark name of a water-displacing spray

… and the definition of “water displacing spray” is “penetrating fluid”

It definitely is an oil, it definitely lubricates. But we normally name things by their primary purpose.

PB B'laster is the gentleman's penetrant. I don't really have a use for WD40.
