Hi I'm a new Hybrid-er and I must say it's quite amazing; however I am a little disappointed by the mileage (39.9 MPG, 2006 Honda Civic Hybrid) at 3000 miles. I'm just wondering what type of "incubation" period should I expect for full mileage?

Also are there any after-market battery/electic modifications (like for the Prius) for the HCH?


Thanks a lot
