Real World D4 fuel consumption

[JayBee75]

Hi guys, looking at changing the D2 over for a new D4, went into the dealer today and it was pretty hard to get someone to sell me a car, walking away with a tech sheet 1 minute of someone's time and my total disbelief in their very poor sales skills, which if they asked me the right questions would have got further, maybe even a signature, but I digress.........

My question to the D4 owners out there in particular 3.0l owners is how are they finding the consumption. I know it's going to be alot better than a V8 D2(just) but for such a big car I am amazed at the claims around the 10 mark. I do prefer to measure in 'real life terms' in the sense of $120 fill I get 600ks hwy and city etc. I find the liters per hundred really does not put everyday situation into perspective.

So out of interest how many k's are the d4 owners getting out of a tank? Btw what is the tanks capacity? The salesman had no clue, I assume 80 odd liters.

Thanks

My 3.0 with rural use normally shows a distance to empty of around 680 kms on a full tank. This is about correct unless my driving circumstances change. My average fuel consumption display has been adjusted so that it reads quite accurately with my normal driving and it normally shows between 10.5 and 11.5 L/100 kms. Low consumption is not top priority with my driving but I do avoid using fuel unnecessarily. I often use the 3.0's torque using command shift rather than allowing the engine to rev.

Around 10.2 to 10.5 in day to day commuting / around town driving. Under 8.5 on long highway runs.

The dealer told me the tank is 84l useable.

I have a long range fuel tank added and after driving from Bathurst to Port Pirie on the way back to Perth after buying the car in Parramatta, I put just over 100l in the long range tank and only 50l in the main tank, despite it telling me I only had 30km to empty with the red light on.

On the trip back to Perth it was getting about 12l/100km with the cruise control set to 119 on the Hema GPS. Since then I have been getting less than 10 around town and in the country at speeds of up to 110kph.

On Sunday the instantaneous fuel consumption was up to around 60l/100km in soft sand for a long period of time but even then the average only increased from 9.5 to 11.1 on the computer after 50km in the sand.

By the way, the disco 4 is incredible in soft sand and runs rings around my 6.5 Chev diesel powered GQ Patrol with 12.5 x 33 inch tyres, even with the standard Goodyears . The only problem is my pristine new to me car now has bush pin striping!

I've been recording 'actual' running costs since picking up a new D4 29 June '11.

Best is $95.81 for 812km.

Table below (hopefully it formats OK) is a record of my experience... aside the perma-grin!

Note:
Refill:
1 - high due to Dealership running
5,7,13 - mostly city crawl stop-start
2,6,8 - mostly highway
rest - around town, to-from work, in the ACT

Graeme.....how did you adjust the fuel consumption to give a more accurate reading ? Is this a dealer fix ?
Mine hovers around 1.5 litres per 100 out. It's pretty poor when computers should be accurate.....maybe poor programming.
It was looking good, until I started checking it at each fill. I have found that I use about 1 litre per 100 more than my touareg, but it is heavier.....but I also use a lot less right foot then when I drive the touareg.

I used Faultmate to change the CCF fuel consumption adjustment factor from the original +7% to -4% after much monitoring.

There is quite a lot of information on this exact topic on an existing thread here:

Thanks Guys, interesting figures.

So the tank is 84 litres, which is the same as the D2

Would be interested to see other people Klm's per tank, but it looks like on avg people are getting around the 800k mark, for a $100-$120 fill dependant on the price of Diesel?

JayBee: on a recent 7K trip, perth-nullabour-lake eyre-lake torrens and surrounds, my D4 3L did 11.7 l/100kms overall. Included a fair bit of dune, claypan low-range in SA, and a high roof rack load the whole way. Consumption calculated empirically - sum of all fuel put in vs odometer reading finish-start. Without a LR tank, this gives theoretical range of about 700kms, and in practice (if no LR tank or jerries) then gives me a practical range of ~600kms. For our SA trip I carried 2 jerries, and practical range of ~1000 kms. Of course totally depends on the mix of on and off road work, but this might help you work out what to plan for, on an extended camping/highway trip. My experience I think seems fairly typical of the recent D4s.
