Do some oils dry-out better than others?

I had a milky looking oil on the dipstick this morning. After about an hour of driving around I checked it again and its clear as a bell. It's supertech hd30. I've run other oils that don't clear up. I guess some additives bind with the water?

I'm going to have to run the car every day to keep the oil dry.

As long as you get it good and hot every time it is started all the condensation should evaporate out. Brand or oil type should not matter

Sounds like you have a small coolant leak, or else you're driving repeated short distances in very humid atmosphere. The PCV system could be faulty too and not evacuating the crankcase very effectively.

A monograde like the HD30 you are using should heat up quicker than a multigrade like 5w30. Maybe that's the difference.

Cracked block. At the bottom of the bores.

I'm going to grout the water jacket an inch or 2 for a permanent fix.

No, additives don't bind with water. You need to stop driving it after a long drive, until it is repaired.
