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.

I know when people read these reviews they wonder if they're really real. Well let me be the first to tell u I'm 100% real and this device was the deciding factor on whether I should trade my Tahoe in or not. I love my Tahoe again and wouldn't trade it in for anything. This little device is worth every penny. Don't worry about getting it at a deal. It works 100% and doesn't effect the ECM in any way whatsoever. Unplug it and AFM turns right back on. Three thumbs up
