Car specs

Turbo - TDO4
AirFilter - Stock
Oil -  Liqui Moly Fully Synthetic
Tires - 215/65/16 Geolanders
Manual gearbox

Additional mods:

Remapped and De-catted with a free flow rear box.

So far things aren't looking very promising. Im a tad above a quarter tank left and I've only done 320km. Open road speed about 100-110kph, mixed driving conditions, including about 20km of gravel (which I think affects range drastically)

Ill be running the car till the light comes on.

Eventually did 345km before I refuelled at about 1/4. Did 8.8km/l driving like a granny. Guess she was labouring. Next full tank I caned it and did 290km also to about 1/4...

Guess Ill be caning it then :D :D

Interesting, I also find very little difference between miss daisy and giving it horns, except for the enjoyment factor that is [emoji1]

I can see my fuel gauge move if I floor it for a few km. But I can see the difference between 10km/l and 8.5km/l by driving carefully or hard. Open road I have seen 11.7km/l

Rural open road at 100 with cruise control on. Lots of cops so I just set it on the limit and relax cant remember what the wind was doing.

Around 5000km after a service it starts using more fuel.

My Foz did a trip from DBN to Alpine Heath Northern Drakensberg with 4 adults and a boot packed to the brim with booz food and luggage, heavy rain for half the journey meant speeds remained 100 or below, very relaxed driving style all the way, fair bit of dirt road and a little sight seeing detour during the weekend. 

Managed to get to 550KM on the tank with the needle still half way between quarter and empty, my experience with this car tells me I'd definitely have made over 600KM on the tank if i let it get into reserve before refueling, but sanity prevailed and filled up at Mooi River Plaza just to be safe. :o

The only thing that all of you have in common is that you all drive facelifts. Could the facelift be that more aerodynamic?

Just a thought, my calculations were on the on board trip figures not GPS verified distance, I know there's a variance when calculating distance on trip vs gps, but how big a variance i don't know.

I know running larger tires or more aggressive tires will affect the consumption negatively. There was a definite increase going from 215/60 hts to 215/65 ATS (bigger and heavier)
