Everyone should bear in mind the fuel computers are generally optimistic. Best to manually work out the mileage a couple of times and then you know what % to add to the displayed figure.

I have done about 28,000 km since Nov 08. Driving mainly M4 and Parramatta Road with some longish holiday trips. Fuel consumption averages 11.3 (or there abouts) l/100km
I should mention this is based on km traveled and litres used. The computer seems to read around one l/100km less.

I am a new D4 and Landie owner, still learning about the vehicle. I have noticed at times the D4 will stay in 5th gear while cruising on the freeway, with an obvious increase in motor revs. ( and fuel used ) I haven't been able to peg under what conditions this occurs as yet. It certainly isn't a cold motor.
Using the command shift and going up a gear to 6th fixes the fuel use, but it begs the question ..why ....and is this something new for a D4 compared to the D3 ?
I too am shortly to be a 2.7 D4 owner and am looking forwards to doing the whole fuel thing. I expect to be able to comfortably beat the AS average. Current car, 3.0 outback, is averagein 9.6l/100km instead of the govt figure of 11.5.
Living in Canberra, I can got to/from work and only have to stop at a couple of sets of lights each way on a 25km trip, while averageing 75kmh (short 40/60 sections, short 100 section, mostly 80/90 travel withouth lights).
I'm also sure it SHOULD (magic escape word - should) use less fuel than a D3 in the real world based on the 140kg lighter weight and the 5 - 10% better aerodynamics (depending on which road test you read).
The govt figures are based on putting the car on rollers for a set period at 60 and 100 (5 and 10 mins I've been told) to 'simulate' driving. So, given the test figures for D3 and D4 are identical, I'd have to assume less in the real world.
As shor term anal retentive, I'll run a spread sheet for 3mths with every km travelled/fuel used/cost then get bored and stop.
That should be 38,000 km. the actual average is 11.21 l/100km, the best figure I got was 9.65l/100km from Dubbo back to Sydney.Quote:

Back to the original question... it really depends on where you drive. If your drive means you can average about 80km/h, you will get better fuel economy than through traffic averaging 35km/h. When I drive to work at West Pennant Hills, I get about 11.5L/100km/h. Even then, it would depend on the time of day you travel! So lots of variables to answer this question correctly!
Good luck with your new toy Michelle!

I suspect its more of a function of the 110 kph constant speed in hilly terrain than the lack of run-in after 11K. Slower driving is definitely better for fuel economy but sometimes fuel economy isn't the highest priority criteria.Quote:

My brother has the 2009 RRS with a 2.7. He drives his car like he stole it, tows a 2.5T boat, and from my calulations from his fuel card dockets over 6 months gets about 10.9L/100km combined.
On the weekend he had travelled 750km and the trip computer said ha had 70km left in the tank. This was a mix of 3/4 highway and the rest city
Hope this helps
