Salam to all.I have a Honda fit hybrid near 6 month now and i wanted to share some tips..
keep in mind that a lot factors affect mileage.for example
~ Fuel quality(i have tested many times now normal vs hi-octane,later gives exactly near 2 km/L more,i.e if u are getting 20Km/L with normal fuel you may get 22Km/L with high octane)
~ Spark plugs
~ Air filter condition
~ Your driving style
~ Tyre air pressure and type of tyres
~ Weather conditions,like summer winter
~ Air conditioning
~ Engine oil viscosity
So lets assume you have all above in good condition.the main tip is that as fit has bigger engine and IMA to help it,so dont be shy to accelerate.i mean not so hard but dont drive like a 660 cc car to save fuel.
When you have attained your desired speed,lighen your foot from accelerator slightly and look at speedometer.keep lifting your foot and you will notice that there is a point where speed is constant despite your foot much lifting off of accelerator.
thats the point to get max mileage.you will be surprized by noting that when you are thinking i have lifted so much foot off the paddle and the speed will decrease but it wont.that is the point. learn to master that point. and dont shy to cross a car,just accelerate enough and you will see the IMA needle moving very right to help you accelerate.so you wont burn much fuel by a slighly hard crossing as batteries will take care of that.below is the video i made but when shifted that to PC i realized it was tilted but you will get the point.ignore the heavy rain sound at the end

Other point is that as Fit hybrid cant run solely on batteries like a prius so dont expect most mileage at lower speeds like 20-30Km/H, fit has best mileage at 40-90Km/H. so remain in those speeds if easy for you.
Here is my mileage.
normal lahore city driving with flowing trafic =upto 25Km/L
Traffic jams,low speeds 20Km/L
Long route speed 90 = 22Km/L
Speed 100-110= 20 km/L
Speed 120-130= 17-18 km/L
Speed 140 = 15-16 Km/L
at speed beyond 90-100 again the mileage drops because at higher speed batteries dont help so much
Normal city driving
Today 24 Aug with humid and hot waether,went to anarkali via mall at near 2 pm,so you can imagine the traffic etc.got 19km/L with near 50 km trip.
Also do note some other things about Fit hybrid
Engine oil capacity for Honda fit 1340 cc = 3.4L Gp4=3.6 L
Viscosity= 0W20 (you can find Mobil1,Zic and Ptt performa in this viscosity and many others but i prefer Ptt performa at this point). may up by 0W30 but not beyond that
Oil change interval 5000 Km (i know that is bit early if you use synthetics,but as these oils are thin,they suffer more wear tear,so better change at 5k in summer and may be 8k in winter)
Air filter recommended is oil based whitch is very expensive near Rs .4000. change interval 10,000 Km.not available at Honda but at oil shops
you can use normal air filter too,your choice costs near Rs. 700.
Spark plugs
Gp1= VFKH20 Qunatity 8
GP4/CRZ = DK20PR-D13 Quantity 4
performance plugs VFK20F
Honda insight = VFKH20 Quantity 8
DENSO (JAPAN) has started selling the new Double Needle Iridium Tough VFKH16 and VFKH20 spark plugs
So GP1 and honda insight guys get those ones when you change plugs
