Oil or grease?

[Sergio Natali]

I was wondering what other Luger enthusiasts prefer to use on their guns, not necessarily only on their Lugers.

They say that "nothing works better than a well oiled machine" and I think a firearm is no exception.

Different firearms owners seem to have different preferences based on what has worked better for them.

As a general rule I've always thought "oil if it spins, and grease if it slides" where spins includes rotate like a trigger pivot point, everything else is sliding.
To me a light coating of grease stays put, especially on metal framed gun rails, and keps lubricating long after any oil has flowed away.
I always apply lubrication (oil or grease) only to well cleaned parts.

Some people seem to use straigh synthetic motor oil, and apparently it works.
