I have small tip for city driving with mediocre traffic.
Don't drive sedate unless you are tired
instead accelerate a bit and change your gears frequently to match the speed. Obviously you need to overtake vehicles quickly in this process; you will see increase in FE at least by 2-3. This works best for me.
I have observed the same thing in my WagonR. Change the gears to keep the engine between 2-4k rpms and the FE remains consistently good. It's a different story in open roads, where cruising rpms of upto 3k rpms gives the best FE.
