Oh, the disappointment ...
 

... when your car's built-in instrumentation indicates 2.6 kg / 100km

but the fill-up turns out as 3,25 kg / 100km :(


CNG, so it's weight / distance for me :cool:

That's still not bad.

Though given gasoline is about 0.7kg per liter, not as good, I'd wager, as you get on gasoline?

Its normal for European car. The MPG readout is always optimistic so average Ruropean consumer feels good. My car (Renault ecu) says i drive for 4.2 l/100 km, whereas my spreadshet says its around 4.8 to 4.9.
Average consumers do not have spreadsheets with tank-to-tank average to check, I suppose.

I can't choose gasoline
Car only switches to gasoline when the natural gas tanks are completely empty.

Tried it when it was still new, but found it hard to get it under 5 L/100km (over 47 mpg) - that means 200km before running it dry ...

It's tailored to run on CNG.

On gasoline @ 5L/100km, the fuel price would double

That's better !

2.91 kg/100km which accidentally matches the eco-up's rated CNG consumption

But ... this was done on Low Calorific Value CNG, whereas the up! was officially tested on High Calorific Value CNG that contains about 20% more energy/kg :)



One of the hypermiling tips is "Join a fuel-economy Forum"

Please add "Rejoin a fuel-economy Forum" to the list :D

My eco UP! Fis shows about 100 grams too little. I’ve got couple of tanks with 2.2kg calculated but it was 30C heat then. Now with -9C I’m lucky to get 2.9kg

Mine usually indicates 10% or more too low

With AC, gas consumption is about 0,12 kg/100km higher - but in city driving, AC can double the consumption !
On the up!, you can feel the power it takes off the engine :eek:
