“WD-40 performs worse than oils” because WD-40 is not an oil, it’s not even a lubricant. It’s a water protector. many make mistake using WD40 for lubricating everything because it’s mainly for water related applications. There are flavours of WD40 that are more “oil”.

A coworker was asking if someone had some WD40 they could bring in because his chair was squeaking. "I do, but I'll bring in something else for your chair." Another coworker asked "Are you one of those guys that believes WD40 isn't a lubricant?" to which I answered "Absolutely."
