Hiya MM...

I drive mine exactly the opposite. I get it on boost ASAP by taking it out to 3300 to 3600 thru the gears so the revs do not drop below about 2200 and boost holds up at 16 to 18 PSI until I get into 4th/5th depending on spped limit.

Now had the vehicle for 80,000 K's and over that period it has averaged almost exactly 12.5 LPH.

When touring with the Camper the vehicle would be over GVM and the camper maybe 1100 Kg but I do sit around 95 KPH where the fuel flow on the scangauge is the sweetest unless there is line haul trucks catching up to me in which case I sit on 100 till I can get over and let them past.

Totally agree about losing the CC on the hilly stuff esp in a manual. A human who is looking after fuel and engine load rather than launching over the top at max noise will always outdrive CC in the hills. Us humans can also take much better advantage of the ECU fuel cut. Again a Scangauge (or ECUtalk) proves that every time or at least mine does.

Bottom line tho... I don't know why it is but some trucks are thirsty and some aren't and there doesn't seem to be a thing you can do about it. I have a 2012 Navara king cab 4cyl in the work fleet that will not get less than 15LPH no matter what. Usually up in the 17 to 18's...everyone hates the POS.

my 08 CRD is set up exactly as my GQ 4.2 PETROL, just does not have roof rack on and fuel consumption is in the 14-20LPH range - not very amused, the GQ fully loaded touring OZ was 18-25 LPH. I have noticed too that when I travel home from Perth my fuel consumption is less that the trip up. Wondering if fuel quality plays a part as well. CRD is chipped as well, that is the only difference from the GQ

Hi all,what an interesting thread this one is,regardless of which vehicle you drive ( Nissan,Toyota etc.) there is always much debate over fuel economy and no one really has the anwsers do they. I currently drive a 2011 ST Auto which i bought new and compared with the 08 STX Navara i previously owned the Navara was a better overall vehicle.None the less i have just returned from a 7000km tour from SA to Qld and back towing a Cub Spacevan Drover(about 1.5t loaded) and tried all different driving styles including,no overdrive,no cruise,100 khp to 115 kph etc,etc, in my opinion it made little difference how i drove it i consistently got 17 - 17.5 ltrs per 100 kms,now some may say thats high but lets all remember we are driving a truck not a car and if you tow anything forget ecomony.I am most impressed with the overall towing capacity of the auto and found that leaving it in overdrive and letting the gearbox do all the work was the way to go ( even in temps of 40+ ) After driving 7000ks the vehicle was very comfortable and offered everything you would need while touring.If you are looking for value for money,buy a Patrol.

Hi there - just to add to the debate - I get around 11-12.5L/100km out of mine out of all sorts of driving conditions (and have winch, steel bar, snorkel) and carry loads of approx. 300kg quite often. Haven't towed yet so can't comment on that but have standard tyres and suspension until next week.

Coldcomfort - you mentioned 145L main tank? Have you upgraded your tank as I believe the standard main tank in GU 7/8s is 95L so I am guessing you have a LR tank?

Hi my GU8 is 3 weeks old and its been getting mid 11s its got a 3inch lift,285km2s,steel bar,winch,snorkle,steinbaur chip set on its max setting,dual batterys and im loving it.

Looks like most are in the better fuel economy range, and there are a small proportion that are high ( Which is consistent with other posts about the same topic ).

If you want to go ahead and purchase a car, and also want to confirm that that have a good one, you have twp choices.
You either take your chances, as I have done with the last two CRD's I have purchased, or I would either see if you can put a clause in your contract with the dealer stating that if the car after the first tankful returns a reading over 14L per hundred, then you can return it for money back, orf alternatively after you have haggled and got to your agreed price, as the final kicker to sign the contract ask for them to fill the main tank whilst you watch, on the vehicle that you are going to purchase - go for a 100 klm ride, and refill to the same point at your expense, and calculate results
