I live in Michigan and I drive my 1930 Model A any time the roads are clear and dry until the end of December. When it is really cold I always let the car idle until it has warmed a bit before I start driving it. It also allows the thick transmission oil a chance to warm enough to allow me to shift without straining. I run a synthetic 10W30 oil with a full flow oil filter.

During the summer the car only uses/loses about 4 ounces of oil in 1000 miles of usage...when using the car around 20 degrees F it can use/lose 16 ounces of oil in a matter of 200 miles. I also noticed the breather fills up with that watery foamy stuff too. I think a lot of the oil is coming out of the rear main, but I am not sure. This happened last winter too...and then returned to normal when the weather warmed up.

Is cold weather a problem for model A's?? Or do I have a problem??
