Here are my fuel/distance records for those who are into statistics. :P It's an export from an Android App I use called aCar.

Most of the driving is around town (<10 km trips) and you can see where the economy is a lot better for those long distance trips on highways.

For those who like Litres/100km, then the data is there for you to massage as well. Sorry for the American date format.

[Edit - just looked at the formatting and it is terrible! I will update it tonight for you all]

Craig I haven't done a 'proper' consumption check - just using the in-car Guess-brand computer, but my RRS 3.0 gets around 12l/100 around town, and about 9 on the open road.
Towing a one-tonne camper trailer for 5,000 km at an overall average speed of 75-odd, it was up to 14.5, but that included some pretty heavy duty sand and creek-crossing work. (Mind you, it has had the ECU re-mapped, which is sure to add something to consumption figures.)
Then again, I've never been overly concerned with consumption per se, it's more about range for me. I just wish the tank was bigger, like my Prado - I loved that 180 litre tank, even if it was petrol.

I have done just over 5000 km in my D4 3.0 SE and I am averaging 9.8 to 10.0 lt/100k on the computer. I have not yet worked out any actual figures from fuel and distance but when you do this, youhave to correct for speedo error, which is about 4 to 5% on my Disco. Mynormal daily run is around 50 km to work and 50km back, mostly on 100kmh and 110kmh freeways. I am not known for my light foot and I normally cruise 3 to 5 kmh over the limit if the traffic is light.

I have noticed that if I take the coast road home, with an 80 kmh limit, my average consumption drops dramatically. The mathmatical formula for air drag is a function of the square of the speed, so this is to be expected. The difference between 100 kmh and 110 kmh is also quite dramatic.

This is still very impresive fuel use for a 2.7 tonne vehicle shaped like a small block of flats.

Cheers

Whats weird is driving at 100kms my trip computers says its doing 6.9L/kms on the instant mode. As soon as the freeway kicks to 110kms, it jumps to 8.2L....

That 10kms speed increase make s big difference!

I have done this test several times now going down south, overall with the mix driving it really averages a proper 9ish litres per the 100kms.

Whilst my speedo is 5 kph optomistic at 100 kph, the odometer has matched the freeway speedo checks the few times I've checked. Hence on mine at least there would be no adjustment for distance travelled.

Hi all, did a four hour round trip today, mainly freeway at 105kph.
The car puter was showing 8.3Lt per 100Klm's when I returned.
Pretty happy with that.
Cheers, Craig

According to my GPS, mine speedo is the same.
