  1. Denso Iridium spark plugs, identification, indexing

    Problems and Troubleshooting
    1. Are the specs on Denso 3421 (SK20HR11) iridium spark plugs the same as the specs on Honda OEM plugs for the MT 2000 Insight? I had new plugs installed by mechanic and car seems to be misfiring along with MPG now 30-50 (was 50-80mpg). I thought that could be the cause. I believe I have the...
  2. Fuel economy mods - by the numbers

    MPG Issues
    We have owned our 03 Insight for 5 years. The car has been my wife's daily commuter until the last year and a half when we decided that she needed an SUV. So we found a Ford Escape Hyrbrid as a compromise vehicle so that she could get the 4wd and space she wanted and still get respectable fuel...
  3. Over 300K miles on '01 Insight 5-speed

    MPG Issues
    My 2001 Insight 5-speed has over 300K miles so far. I've started designing a "panel" that will allow me to erase the memory in each of my sub-pack batteries. My goal is to build a tool (or technique) that will allow me to fully charge my battery pack such that it will function properly (be...
  4. 10 MPG lost in past 6 months - cure?

    Problems and Troubleshooting
    I wonder how to bring back high MPG in an '01 stick shift. Gradually, avg. MPG has slipped from 64 or so to 54. I had averaged around 68 summer, 60 winter, until last fall. At first I thought it was due to a change from mostly highway to mostly local driving, but we just took a 200 mile...

  7. Good reference Car&Driver article effect of tire/wheel changes on mpg

    MPG Issues
    Everyone interested in their mpg should read C&D's article on pg 32 of the latest issue. Well stated and we can attest to its validity. Wider, heavier, larger diameter tires cut mpg and acceleration.

  10. Insight 2 Lifetime MPG Display?

    Honda Insight Forum 2nd-Gen Discussion
    Does the new Insight have a display for lifetime MPG? I was told by the dealer that you can customize features and displays but he didn't know if that one was available. I'd look in the manual but I don't get my new car for a couple of days yet!
  11. Low Gas mileage? Spark Plugs

    MPG Issues
    I purchased my 2001 MT Insight a year ago at 104k miles and in the last 6 months I have noticed my MPG drop to just under 50 with 90% city driving and only about 55-60 on the Freeway. Having implemented all the basic hypermiling techniques (tire pressure, pedal usage, coasting, etc) with very...
  12. CVT coasting in Neutral?

    MPG Issues
    My 2002 CVT Insight has only 31000 miles and a LMPG of 39.4. I suspect the combination of a heavy foot and low daily stop and go mileage in the city is to blame. Nonetheless, even when driving pretty compulsively I have never gotten good "Insight level" mileage. Recently I have tried shifting...
