What MPG improvement did you see from the grill block?

As you can imagine, the load acted as the opposite of an aerocap. The wind resistance was tremendous, and I drove about 50mph for my 70 mile trip. It was early morning and the State Patrol would observe me a while before deciding not to pull me over. Still, I averaged 18mpg overall for that tank.
