Use lube - it should do the trick

Last time I checked oil was a lubricant.

Who's the dipstick now ?

Nothing to worry about at all! The oil is hot and once the dip-stick is out the moisture in the air evaporates.

If the moisture were to evaporate, you would no longer see it.

It is moisture condensing that you see. i.e. steam ejected into the relatively cold air produces 'clouds' of moisture.

There should be no moist air coming from the dipstic hole.

Have a read up on psychrometry, it will explain all.

Has the car done a high mileage?

Its possible that the PCB is blocked, but most likely its just oil mist condensing in the cold air.

Don't think it's related to the crank case breather in this case (although if there was pressure in there and a lot of vapour you have a definate point) - once the dip stick is removed the vapour will take it's easiest route - which is up and out.

Quite normal.

It is always a good regular check to clean the PCV though.
