If interested, attached is a picture of our most recent mileage summary from a trip to Chicago and back. Considering the highway mph, 70-90, better than I anticipated. We did have one "Red Wrench- Service the System" error message show up. Luckily it went away as quick as it appeared. It appeared on the highway portion or the trip out, at highway speeds.
