New air dam

[JRMichler]

And now for some results.

Since I installed the air dam, nobody has had anything to say about the air dam, while several people commented on the topper. I take this to mean that the air dam looks close enough to "normal" that nobody notices it enough to mention.

I now have MPG results from December 2016 thru February 2017, the three months that I use to calculate winter gas mileage. My mileage for Winter 2016-17 was 33.0 MPG, while the best previous winter was 2015-16, where I got 31.75 MPG. I no longer drive three miles each way to work, so that should improve mileage by 0.7 to 1.0 MPG. The improvement attributable to the air dam is thus 0.25 to 0.55 MPG.

It will be interesting to see what I get for mileage next summer, because I averaged 38.6 MPG last summer. I really want to get to 40 MPG.

Anti-spray brushes in the wheelwells down to the tops of the tires. And mOOn disks.

I had had hopes for wheel covers, so I tried them Summer 2015. I did not get a measurable change in fuel economy.
