Did you cut the top off a bumper? Any details would be much appreciated.

Yes, I cut off the top section of an extra bumper cover and used it as a splitter. Obviously it perfectly matches the contour of the bumper on the car. It sticks out past the original bumper, moving the stagnation point much lower. I hope I'm using that term correctly! I believe it's keeping air from going under the car without adding frontal area. No ABA testing done, but I did get my best highway trip mileage after installing it.

Gasoline Fumes, that is some exceptional mileage from a Civic Wagon, especially considering your location and the weather this winter.

That's a great idea.
How did you attach it to the bottom, and how much did it raise up your mpg? |

Screws from underneath. And a few carriage bolts for extra strength. I can push snow around with it. 
Other factors were involved, so I can't say for sure, but it seemed to give me about 5 MPG at around 55-65 MPH on highway trips. And that's compared to an airdam I had on it before. I barely believe the results myself.

Here is the aluminum version of my grill block off. I used the license plate bolt location to bolt it to the bumper

I don't think enough can be said for preventing under body flow.I'm still re-testing on the T-100, as the numbers since the addition of the airdam were so weird.
