Checking with a Honda Civic Si in Masachusetts

[-mr. bill]

I have a 2006 Civic Si that I bought in January 2006.

(My "mid-life crisis car." I went from a Taffeta White 1998 Honda Civic LX Sedan to a Taffeta White 2006 Honda Civic Si Coupe. On a scale of 1-10, this is about a 2 on the mid-life crisis car scale.)

We live near Cambridge MA and I face a 40 mile commute each way - luckily I'm commuting against traffic.

My typical route out to work had been:
* 2.5 Miles of city (20-30MPH, 6 stop lights, two stops, BIG hill out of the valley)
* 10 miles of rolling (predominately UP) hills at 55MPH on a state highway
* 11 miles with 7 stop lights (plus a rotary) at 45MPH
* 6 Miles of rolling hills at 55MPH again on a state highway
* then 15 miles or rolling hills on an interstate at 65MPH
* 2 miles of city, 1 stop light

Home route was reversed 3 days a week, but 2 days a week I'd end up taking back roads rather than highway, more stop lights and stop signs, but takes the same time as the congested afternoon interstate.

After the brief break-in, I averaged 28.0 MPG over 31,000 miles through April 28th. Old-school EPA combined is 26 MPG . I did have 8 tanks over 30, with my best tank was 31.1 MPG on a trip back from New York with four on board. (124 PMPG!)

Got tired of waiting for the data-logging Scanguage II, so ordered the existing one and installed it on April 28th. First tank 33 MPG. Now we're talking. That puts me right back where I was with the 1998 Civic LX.

Since then I've been doing better and added another tool - Google Earth, trying to find "flatter" routes. My goal is actually not best MPG but least gas for the home-work-home route, but I just did over 200 miles at 40 MPG the past couple of days.

Nice discovery was that the Scanguage II doesn't know my K20 ECM will shut fuel off on engine braking above about 1200 RPM. With some of the significant downgrades I can engine brake with zero fuel for over a mile. While I try to avoid brakes around town, the pedals are placed perfectly so that I can light the brake lights, briefly blip and downshift and get what I've been calling "i-FREE-TEC."

(And yes, I drove a vanpool for 12 years. Several years I worked in New Hampshire and my spouse worked in Rhode Island.)

One stupid question. I've got 100 old tanks for the Si to enter into mileage logs, can I add tanks "backwards" in time?

welcome, mr. bill. sounds like you have a good momentum going and a lot of knowledge to bring with you.

as far as the tanks, not sure what wayne would do, but yes, you can add them backwards in time, the date is changeable. what i did when i came in from another site was just use the total number of miles i had driven and the total amount of gas and added it as one big entry........whatever works best.

Welcome to cleanmpg.

Yes another Civic. Yeah know Yari are taking over the world.

The Si should lay down some good numbers. If its anything like my EX speed kills the mpg something awful. Wind isn't its friend either.

Glad you here. Enjoy the stay!

I will forward this thread to my wife. A proof that you can have a SI and hypermile.

(Welcome on the site)
