Okay, guys, I am completely in love with this whole thing. I filled up this morning after about 18 days of REALLY trying to incorporate as many techniques as I could (safely of course, given my inauspicious beginning

). The result: 39.9 mpg!! I am thrilled.
This beats highway EPA by almost 3 mpg and was almost all city, WITH a roof rack, a giant dent in the hood that is probably heinous for aerodynamics, and at least 3 or 4 trips when my wife took the car and drove normally.
The roof rack is coming off after a trip to Lowe's for some carpet, and I'll be calling junkyards looking for a Civic that was rear-ended! Time to get as "slippery" as possible.
Just a pair of mileage log questions:
1. How do I get this cool thing to work?
2. and this?
Thanks!
