My 2nd Honda Insight

[Gasoline Fumes]

69.3 MPG on a recent 334.2 mile trip. Some hypermiling, but mostly 55-70 MPH on the highway with the windows slightly open. No aero mods yet. Still missing all front under panels. I have Coroplast, I need to use it!

I'm hoping the EcoModder decal improves fuel economy!

Mine definitely does!

I changed the oil to Mobil 1 AFE 0w-16. And took out the wrong indexing code spark plugs and put in used plugs with the correct codes. I also tried more valve lash to get more low-RPM torque. I'm not sure if it made a difference, but it's noisier! Next up is cleaning the EGR.

I found out the IMA battery was replaced 5.5 years and 32k miles ago at a Honda dealer. Trying to figure out how much it's worth so I can sell it.

It's worth whatever someone locally will pay I believe I got $700 for mine, but I'm somewhat of a Craigslist superstar.

Still haven't sold mine yet, we'll see what happens.

You might have better luck if you brought your battery to InsightFest and tried selling it there.

I'd probably go to InsightFest if it wasn't the same weekend as the vintage racing in Watkins Glen! I have a couple of potential battery buyers local to me.

I sold the IMA battery for $700. I got paid to install it too. And the whole car was only $300. I like cars that are cheaper than free!

Still getting "only" 70-80 MPG. Maybe I shouldn't complain!

EGR plate and passage cleaning didn't seem to accomplish much, but it needed to be done.

I have a P1457 EVAP leak. According to InsightCentral, it's probably the canister vent shut valve.

I'm getting a part-throttle bucking that I'd love to eliminate. I'm going to replace the TPS and see if that helps.

I need to replace a seized parking brake cable, a leaking rear wheel cylinder, and the warped front rotors. I have the parts, just need to get them in.

I also will replace the radiator before it starts leaking and install a block heater.

On a recent short road trip, one of the large plastic aero panels under the car caught the wind, dragged on the highway, and eventually folded under itself. I removed the mangled panel and will use the good one from my other Insight.

I'm probably going to remove the electric power steering and ABS brakes. Undecided about the A/C, it doesn't work now.

[mpg_numbers_guy]

I just sold my IMA battery yesterday for about that.

Replacing the parking brake cable isn't too terribly difficult. Mine took a few minutes longer due to removing my underbody paneling. Have you checked the drums themselves to see if any parts are missing? My driver's side was missing the parking brake lever (in addition to the seized cable) so I replaced both the cable and the lever.

Do you find yourself hypermiling less in the Insight than in the Civic?

[Gasoline Fumes]

No parts missing on mine, just a mess from the leaking wheel cylinder. But on my friend's 2002 CVT Insight that I installed my battery in, both auto adjusters were missing. Not really a big deal. But one brake cable wasn't even connected!

I can't not hypermile anymore, but I would do better if my average speed was a bit lower. I need to leave the house early, not late, when I'm going somewhere! I'm using basically the same technique I used in the Civic. Cruising at light loads (LB), gliding down hills. Cruise & glide? I only do P&G if the road suits it.

I'm hoping a new TPS will help leanburn, as well as cure the bucking. I have trouble staying in LB over ~40 MPH. In my experience, Insights feel like they're always going uphill at about 50 MPG instantaneous. If I cruise at 35 MPH, I can average at least 100 MPG. I was going 45-50 MPH in the Civic on my best tanks.

At least I can see a definite advantage to the Insight on faster highway trips. It'll get 70 MPG in conditions where the boxy Civic Wagon would get only 50 MPG.
