What is the "lube" in lube, oil, filter?

I've always changed my own oil, but what's the "lube" part of the maintenance? Is it just taking a grease gun and going around to all the hinges (doors, trunk, hood, etc.)? Is it really necessary if your doors don't squeak?

Yes. Nearly all newer cars have sealed bearings and joints.

get a greese gun and a tube of greese and just go around and hit anything that looks like it could be a zerc fitting
