WD-40 is not a lubricant because it is primarily a water displacement spray. While it offers temporary lubrication, its main function is to protect metal from rust and corrosion, penetrate stuck parts, and remove moisture. For long-term lubrication, it’s better to use a dedicated lubricant like silicone spray or motor oil.
