Water. Water is the issue during a long cold and lazy warm up. More than a gallon is produced for each gallon of fuel burn. Thankfully most exits via exhaust but the rest ends up in the oil until it boils off. After about 60 Secs (and bags have reached auto level) I drive off gently to minimize idling. Then drive normally but not aggressively til normal temp. On a sliding scale I would adjust times with temp drop. Might be 2 mins below zero and driving more gently at first as well. But road load is your friend in the anti watering war. Also the dash heat will work much sooner and forward progress beats 0 MPG any day.
