Not sure about the white smoke; sounds like coolant in the oil. But your daily drives of seven miles each way is not enough to get the engine to operating temps. Letting it warm up doesn't really help; just wastes gas. I suggest once a week taking it out on the freeway for 30 minutes at freeway speeds.
