    I bought a civic last night after some planning for about 5 months. I expected that with no advanced techniques I would get about 45. Imagine my surprise when I got 50.4mpg on my first 30mi drive in it. This thing appears to be an even better commuter than I thought.

    Now I can finally sell my accord!

    I'm going to talk to my favorite shop about installing the HF underbody panels that improve FE. There is a thread on how to do it at 9thgencivic.com and the parts are just over 100 bucks. I'm going to let someone else do it because - well I can.

    Let us know how that works out. The Civic , despite some hate for its interior , is an excellent car.

    Congratulations on the Civic. I have been very pleased with mine so far. Same reaction when I first started driving it, ...... surprised at how well it does.





    I have taken a quick look under a civic hf and couldn't see any difference in the panels from my 2013 civic coupe.... I'd be curious to know what the difference is and how much fuel economy improvement there could be.

    Other improvements I'm thinking about ..
    LRR tires
    Civic HF wheels (available online for a "reasonable" price)




    My post from another thread:

    So the numbers from the i-MID I've got at 67 ish deg are:

    50 mph : 58.0 mpg
    55 mph : 54.6 mpg
    60 mph : 52 mpg
    65 mph : 49.5 mpg
    70 mph : 45.8 mpg

    In a 2013 Civic coupe LX 5AT, using the finest E0 87 I can find.

    /add, .. I have since run my tire pressure up to 36 psi and noticed a small improvement in mpg, I don't think the ride quality suffered much and will probably experiment with max sidewall (44psi) but I expect the ride to start getting a little harsh at that pressure.

    Looks good carcus. I'm still working on getting my sgii to show the right number mpg (9999) when I'm coasting nice off. Any suggestions?

    Did some testing today, ... going from 35 psi to 44 psi (max sidewall) ups the 65 mph by 2.5 mpg. .... 49.5 to 52.


    /sorry, don't know a lot about the scan gauge.

    Yes!! This will be done Wednesday evening. My wife will be driving it until then.

    Just be aware there is a small degradation in cornering, stopping and ride at 44psi (imo). 36 psi probably isn't a bad compromise if 44 doesn't feel acceptable.

    If 44psi isn't acceptable , you're either a wimp , gimp , or chick. Sorry , just my not-very-humble opinion.

    ... if you're on a gravel road.

    Or snowy, icy roads.

    This car has proven to be really great in highway situations. Pulling 46 on a quick highway commute is pretty easy.
