Yup agreed, your reading is more of a typical FC in most units.
I have noticed that many Cerato owners are very concerned and disturbed with the FC displayed on the HU which actually is the current average FC at that moment of drive. The FC varies from time to time according to the road conditions and your habit of driving.
The FC is worst when the car is not moving with engine idling, aircon on especially during hot weather. You can see the FC figure jumps up scaringly fast. My baby ever went more than 15.0 ltr/100km. Why? because the fuel is being consumed without any mileage covered.
Well, with my K3 I have achieved less that 6.0 ltr/100km during driving on the inter-states 2-way roads at around 90 km/h without much stopping at traffic light junctions. Best testing is during driving on the highways with cruise control on. Setting the speed at 110km/hr can easily achieve less than 7.0 ltr/100km while speed set at 120km/h the FC goes beyond 7.0 ltr/100km. Obviously the higher speed set the higher FC would be. When you want to test out with your babies, alway reset the FC to "---" (meaning "0")before you proceed.
We are driving with mixed road conditions and habbits changing depending on the situation everyday. So it is more important and meaningful to find out the overall average FC. That can be done by, first, top up your fuel tank (capacity 50 ltrs) and reset either of the trip couter A & B to read "0". Then drive with your usual mode for a certain milage (say 50, 100, 200 or more km), then top up your fuel tank again and check out from the station meter's reading or the receipt on how many litres have been pumped in (or litres consumed). So divide the mileage covered by the litres pumped in or consumed and you will get your actual FC in km/ltr. To get the FC in ltr/100km, just divide the numberof litres consumed by the mileage covered and multiply with 100.
If your friends, driving different brands of cars, want to compare with your baby's FC. just follow the method mentioned, e.i. start and top up fuel from the same gas station, set each other's trip counter to read "zero", drive through the same route trailing each other and then stop and top up at the a same station..... No point boosting or assuming each other's FC being the best without actually proving it. One fact, a bigger cc car will not save more fuel than a smaller cc car unless it has special technology break through.
In this case I believe, oddly Cerato's (c-segment) FC can be as good as Vious's(b-segment) because Cerato has 6-speed transmission and low drag coefficient. Vious has only 4-speed.
This is just my personal view, correct me if I am wrong.
