  1. Best Transmission for Gas Mileage?

    Transmission alley
    Hey everyone! I'm new to the forum and just wanted to say I appreciate any help you all can provide! I currently own a 2000 Civic EX 5-speed and I'm wanting to get better fuel mileage out of it. I drive 90% highway and get about 31-34mpg now but my real goal is to consistently get 37-40mpg...
  2. I did some FE testing 64.8mpg

    I have been working on my fuel mileage for the last month and today I got 64.8mpg freeway. I have it running a lean burn mode at 18.5 tp 19.0 A/F. Anyway I had to let everyone know you can have your cake and eat it too. :)
