Theres different types of lubricants for everything.

Motor oil is a lubricant and used in car engines.
White/Lithium grease metals and stuff like that
Silicone Oil for rubber products

There is no such thing as a general lubricant that can be used on different things that I'm aware of.

Also never use WD-40 as a lubricant. I actually found this out pretty recently but you're not supposed to use it as a lubricant because it's actually supposed to be used to strip off rust. However a lot of people do use it as a lubricant.
