  1. Civic Hybrid
    This model of civic is supposed to get 40 mpg city and 49 highway but I'm lucky to get over 30 for city or even 40 for highway. Is there any way to get better mileage? I recently replaced the IMA battery last year so that is new enough and I also got new spark plugs put in. What else can I do?

I’m for sure getting a...
  7. Civic Hybrid
    I know there are more than a few threads about limp/'safe' mode, but mine is specific to the hybrid - 2008, to be exact. So I thought I'd risk starting another one to filter out less-relevant responses. I'm hoping I didn't bite off more than I can chew when I bought this car recently - it was a...
