    The HF has underbody panels to help. I don't know if the hybrid has them, but folks with the LX/EX Civics were putting them on. I have a suspicion they are already on the hybrid model.

    • Drive more efficiently
    • Remove access weight
    • Lower the vehicle
    • Install low resistance tires
    • Keep the tires properly inflated
    • Fill the tires with nitrogen
    • Install a rear lip spoiler
    • Use 0W20 fully synthetic oil
    • Change the engine air filter more frequently

    I checked all the part numbers for the HF under body panels and it appears as if my 2013 LX sedan has all of them installed. I believe it's just the narrower wheels & LRR tires with the rear lip spoiler addition that are different.

    Maybe they also addressed that with the '13. Hmmm. Nice to know.

    Use lighter rims. Don't use the accessories like A/C or defrosters, lowering a window a 1/2 inch helps the windows from fogging up. The whole idea of the Hybrid is to lower the engine loads at low speeds but it takes energy to charge the batteries. Use higher octane gas to lean the A/F at higher engine loads. Get a good reader to see what the ecu is doing, this way you can see what works or don't.

    Any mpg mods?

    Yo I recently picked up a 2015 Civic lx and have been loving the mpgs. So far the highest single trip mpg is 59 and I usually average around 43 per tank. I was thinking are there any mods to improve fuel efficiency further? I was thinking lowering it some might help airflow and perhaps an intake too but besides that im not sure. Any suggestions, thanks!

    Low rolling resistance tires like Bridgestone Ecopias mounted on lightweight rims will help. Lowering the car will also help as less air will pass under it. A catless downpipe and straight perforated core muffler may or may not help depending on the cam tuning. On my DOHC Neons that had 0 cam overlap, it helped as the exhaust gases had a easier time getting out of the engine by themselves without sucking fresh air/fuel mixture out at the same time or creating much resistance for the pistons upward movement on the exhaust stroke.. On my Mazda KLZE V6, it didn't did shit MPG wise but damn in was more snappy!

    If you're not already using 93 octane fuel, give it a try for a few tankfuls. Either way, 59 mpg is phenomenal, as is a 43 average.
