I've just gotten a new Nissan Sunny 1.6 EX Manual last week. When I took delivery of it, the fuel tank was half full. So I drove till it's left with one quarter and pumped it full with Mobil 95 and reset the trip odometer. Drove till around 450km when the fuel low light came on. When I re-fuelled, the distance is 457.1 km and the amount of fuel used is 36.69 L.
So my fuel consumption on my new Sunny is 457.1 divided by 36.69, which is about 12.5 km/L.
Your FC will not be as accurate if you use this method. To better clock your mileage, follow this:
1. Top up till full (till the nozzle stops filling). Don't pump in anymore fuel to make it really full tank (This is important for accuracte reading)
2. Reset ODO and drive as usual for about 100 to 200 Km.
3. Repeat step 1 and note down the amount of litres pumped.
4. Check your Km travelled and divide it by the amout of litres pumped e.g. 150/9.5 = 15.8 km/litre.
Hope this helps.
