3.0 litre GU4 Patrol Fuel Consumption, plus

15lts per 100kms for a 3 tonne automatic cereal packet shape witht the areodynamics of a brick in the burbs is the norm. The muddies migth push the consumption up a bit but nothing more than a 1/2 litre per 100 max. A few good runs on the highway will bring out a decent comparrison, in the burbs it is unrealistic to get much better.

My 2.8TD Manual with 285/75/R16 BFG All terrains would be around this in the city, 12l/100kms on the highway at 95-100km/hr with roofrack, 2" lift, the beerfridge ect. If I go to a 110+ it falls to 15+l/100km.

As for the improvements; DP Chip (4wd Megastores) or Safari D-Tronic (ARB ect.)
Exhaust; Beaudesert exhausts in QLD or Vortex Exhuasts local dealer

That's about normal for the 3.0 Auto just sold my manual and it was 13 ltrs/100km around town and you would expect to use a bit more with the auto. Now have new 2.5 ltr Navara ST-X auto, dual cab and that has averaged 11.2 Km/100Km over 14,000 Km and still coming down.

Consumption sounds a bit on the thirsty side, but with the tyres probably about right. I've got a dtronic in my new GU IV which I took out of my 2000 GU, it does provide a bit of umph at the cost of an additional 1/2 a km per litre.

Jim,

I had a 2002 3l (manual) until Feb. Now have the 4.2. Around Melbourne I would routinely get 12.5 empty with the 3l and around 15 when towing the camper on the highway.

Just did a long run the other weekend with the 4.2 and got 14 fully loaded (roof rack and long range tanks etc) on a highway run sitting on legeal speeds which I thought was OK.

I would have thought you shuld be looking at 13 or less with the auto. How many kms? It might be too early to be checking too seriously.

my 3litre manual 2002 with winch,roof rack weighs 3050 kg and does 8-8.5 k/l round town and 6.5k towing 1100kg camper

You don't say how many K's you have done but my 2005 GU IV ZD30 Auto does consistently 11.5 l/100km. The dealer told me it wouldn't reach it's best economy until it had done 5000km which I thought "sounds like sales b..s" but it actually was true and I record the km and litres every fill since new and always fill it till you can see the fuel sitting in the two filler necks. You have to fill both tanks to get an accurate result because the sub-tank pump runs for few seconds every time you start the engine so if you rely on only filling the main tank you will get a result that would lead you to believe that the economy is better than it really is. I live 65km from the Perth CBD so most of the driving is not true inner suburb stuff apart from when the handbrake does the weekly shopping, etc but I wouldn't have thought the difference would be that great. The only time I got a reading as high as yours which is about 6km per litre was towing a camper trailer out to Steep Point and back again where you are running 18-20psi in the tyres and giving it sh%t to get up the long steep sandhills, where the going is pretty heavy, etc and that reading was only for that section of the trip which I took particular note of for future such driving such as CSR, etc. The only other time I get less than 11.5l/100km is when travelling above 110kph for long periods. Re your tyres I wouldn't have thought they would make that much difference and I always run mine at 34psi when on bitumen. If yours is new I wouldn't worry too much until after the first 5000km but if you have already done that I would get a tune up after you have checked all the obvious stuff like dirty air filter, dirty mass air flow sensor, etc

Jim,
Probably not too bad, suburban stop start stuff is thirsty work for a vehicle the weight of a GU.

As for the Twine I have one in a GU 3 on the firewall behind the intercooler. MAy noy be possible in the later model though as the cover looks to go further back and there may not be the room as in a GU3. I was able to mount the heat exchanger off an existing stud on one end and fitted a nutsert to an exicting hole on the other. A couple of angle aluminium brackets were fabricated to suit. The pump I put in the RHS of the bull bar [steel] Anap fittings under the bat for the pick up and in the enine bay near where the ABS is, small bracket on cable ties around the snorkel to hold the shower head. If you look on the Patrol forum there are photos of similar setups to mount the heat exchanger.

Hi Jim7,
My GU4 3lt Auto does between 14-15lts/100kms in the city/suburbs. 16-18lts/100kms towing on the highway and down to 10.5lts/100kms lightly loaded on the highway. Towing on sand or in the rough is to scary to measure, best just enjoying myself. When I brought the vehicle I expected better but learnt to live with it. It's a little motor pushing a bloody big vehicle.

Jim i fitted a twyne shower to mine the heat exchanger sits on top of the fuses on drivers side running along the axisof the vehicle the pump and switch are in the large gap in front of the radiator and behind the grill tons of space ...

I stopped measuring the fuel consumption so I have no data for you. However I ended up installing the Helton unit. It had top mounted water connections which made it easier to fit in.

Not 3ltr bashing here but am surprised with the fuel figures that are being given for this motor, i have a 92 GQ 4.2 diesal super charged having done 340,000ks and i continually get 12-12.5 city country driving and when towing the camper average 14-15. Next week new injectors and tappets being done so hoping those figures will improve. Col
