Now that the cold snap is over, temps have gone back to about what I had back in October/November. Using the data from then as a baseline, my typical commuting mileage was about 17.5mpg.

With about the same temps and driving conditions I'm now getting 18.1mpg over the last two tanks for about a 3.5% gain.

I'd still say these are preliminary results, as that's only two (very large) tanks of fuel, but it at least looks like it is a positive gain from the grill block and belly pan.
