Works as described, no more excessive oil consumption
Primary reason was to reduce oil consumption. 1 qt Mobil 1 every 2,500 miles; 70% city, 30% highway driving. 2,000 miles in after install and still on the full oil level mark. Not sure how it does it, but it did seem to drain the battery after sitting over a weekend. I have since been unplugging when outside on a cold night (below zero) or if not driving for more than a day.
