I've been "lurking" for a while, and I decided to work on my UserCP (add a signature, etc) and try an occasional post.
Interesting stuff here (on the GasSavers Site), and as fuel prices continue to climb, I hope more information and sites like this one are shared.
Have a good day.
1998 Dodge Ram 3500 Cummins - 17 to 21 MPG
2005 Mercedes Benz E320CDI - 27 to 38 MPG
2007 Mini Cooper S Cabrio "Sidewalk" - 24 to 27 MPG
2007 Chevrolet Silverado 5.3L - 14 to 19 MPG
And...a couple of recumbent bikes.......
Welcome! Start using the garage and track your mileage. I see you already have a pretty good idea of what you're doing.
What I've found is that simply tracking the mileage and learning about improvement methods leads to improvement. The natural desire to improve leads one to naturally incorporate and practice good FE methods. I found this out when I was a passenger with the wife recently, I sure do drive differently than her!
