Check out the 65+ Efficiency Mods. It's an old list but still relevant. What year is your Civic?

Lowering usually helps. A remap might or might not help - you'll have to see if anyone has made one for that drivetrain that actually improves efficiency, and not just power. You won't find any fuel additives that do anything but drain your wallet.
