Spinoff question: Your fuel consumption per 100km

[FifiLámour]

This is a spinoff question from DiscoWeb's "new boots" thread (didn't want to hijack it).

Just wondering what kind of fuel consumption you guys are getting per 100km - both on the highway and around suburbia.

We have a Disco 3 SE V6 petrol:

Around suburbia, it was using 18l of petrol per 100km
On the highway, it's more like 15l per 100km

Is this about the same as everyone else?


Caveat: I've noticed since having my air filter cleaned last week that I am now running at about 16litresl/100km in suburbia. Though some of that would be on the highway so it may be a bit skewed...

Hi Fifi, not sure about about the petrol. I have a D4 3.0 Diesel and average 8.5Lt per 100Klm's (according to trip computer) on a trip and around 9.8Lt around town.

D3 TDV6 SE with ARB Bar and General Grabber At2 tyres. Mix of 50/50 country and town driving 10.0 Lt/100KM or about 10.5 with a windcheetah roof rack on. The bar added about .5l /100Km, tyres did not impact economy to a noticable degree.

I can't help much with the Disco fuel consumption except to say that your figures are only about 2 litres/100km better than my 1973 Series III. Not much progress in about 35 years. :p

However, I would like to say that the fact that you quoted your fuel consumption in litres/100km wins you a lot of brownie points in my view.

I have given up trying to extract something meaningful from comments some people insist on making like, "I get 673 km out of a tank." As far as I can make out that translates into something like, "On one trip I did 673 km before I decided it was time to put some more fuel in because the fuel gauge was getting a bit low, but I have no idea how much fuel I put in."

Thanks for quoting figures that actually mean something, even if they aren't much better than my old Series III used to do. :p

[DJC]

Only had the car (05 TDV6) about 2 months and about to get some major transmission surgery, but mileage has been as follows:

Country/ Freeway - averaging about 10l per 100km

City - about 13l per 100km

Have found that the consumption indicator on the readout is actually pretty much spot on when I check it manually after refills

Cheers

[Dingmark Jim]

My old D3 V8 consumed about 16l/100km in suburbia and down to 13l/100km on the highway. With a camping trailer it was 17l/100km on the highway. ON a long, soft sandy beach (low range, floored) the computer showed 50l/100km over 30 minutes (but the V8 roar made it worthwhile). These are figures calculated by taking fuel purchased / kms travelled, NOT from the optimistic trip computer. The figures are with 98 RON premium fuel (which reduced figures by about 6%). Don't have enough kms on the D4 3.0 TDi to have reliable figures.

2 roof bars
Heap of crap boxed in back.

Just did Sydney > Brisbane 9.6 l/100k per vehicle trip computer. (calculated on fuel fill was 10.22 )

Brisbane > Cairns 8.6 indicated BUT I haven't refilled yet so cant give the fuel fill figure. (range is still showing around 400km to go :angel: (just got in 30 minutes ago....)

My normal around Sydney is between 13.1 and 13.9

[WhiteD3]

Running 98 octane I get 10.x (indicated) on the highway and 15.x (indicated) for a combined cycle of Brisbane CBD/surrounds + freeway, etc. Add say 1 l/100km to this for actual.

I use cruise whenever I can to maximise the economy and use a very light foot around town. Always use 98.

Hi vnx,
You mentioned that the fuel figures haven't improved that much over the years. Maybe the case, however todays engines are producing twice the power & torque.......massive improvement.
I went to the snow the weekend gone. For anyone who knows the area, I live in Mt Martha on the Mornington Peninsula. After filling my Disco, I went to Melbourne airport and back home. I then drove to Mt Baw Baw for the weekend (about 2 1/2 hours each way....winding roads, chains fitted part of the return trip) and back home. Hooked up my boat Monday morning and took it to Dromana for a service, then did the rounds of my building sites in the Mt Martha area.
Then did some running around Mornington that day before filling up with fuel late afternoon. All I could squeeze into the tank was 67Lt.
Not too bad for a 2.5 ton 4WD considering the range of driving that I did.
Maybe this should have been in the stories section?
Cheers, Craig

[FifiLámour]

Thank you VNX (you gotta do apples with apples, don't you) - and everyone else for your data.

http://www.freesmileys.org/smileys/smiley-shocked003.gif (http://www.freesmileys.org/smileys.php) I am sitting here at the pc with my mouth hanging open. Oh. My. God.

It seems my car is burning a whole lot more petrol than it should if I am reading your posts correctly. How could that be??? I don't have a bullbar or roof racks on. Mostly I'm carrying a couple of kids, some bikes or perhaps one or 2 of their mates! Everything else would have to be random - wind factor etc.

It must be my driving??? How can this be? I thought I was a good driver? https://www.aulro.com/afvb/images/imported/2010/08/1302.jpg (http://www.freesmileys.org/smileys.php)

I will wait with further interest to see what other figures come in.

...And focus a bit more on my driving to see if there's anyway I can improve it *sigh*

...And perhaps I should bring this data up with my service people.

Yes, I know. I only mentioned it as a joke. I know it isn't a valid comparison because a D3 weigh about a tonne more than my Series III. :p:p:p

Hi

I have the V8 with pirelli scorpion AT

Beach somewhere around 24 ouch

Suburbia about 16

Highway down as low as 11 point something

Which is good considering all the steel and tanks and winch I have since bolted on and the roof rails

Fifi, If you drive anything like my wife, you need to take the lead out of your right stiletto.
When I drive my wifes car, the kids say "dad, how come you are driving so slow? Mum drives way faster than this".
On a serious note Fifi, you would be suprised at the difference in economy from driver to driver. However, it probably wouldn't hurt to get your LR people to check it out at your next service.
Cheers Craig
PS: Try driving in thongs instead of stiletto's

[tunnelthug]

Fifi,

MY09 V6 SE petrol, always use 98 octane (Shell V-power or BP Ultimate)

Still have the original factory-fit Goodyear Wranglers. Around town between 17 - 18l/100km, on the freeway about 12.5l/100km is the best I've observed.

Would be interested to know what difference there may be with consumption and performance using lower octane fuel - most regional areas apparently only have premium (95 octane) or less.

(For my sins, dare I admit I bought myself an old SWB Paj (1983 model 2.5l TD Jap import) when I first came to Oz - had BFG all-terrains and PTO winch - still could run it on the smell of an oily rag- good if you're a miserly Scotsman like me!)

Leaving the aberration of the Paj and a company Hilux aside, all other off-roading has been in trusty Defenders. Happy to pay the fuel bills for the D3 now, just out of sheer driving pleasure!

Cheers.

Fifi,

Mine is the TDV6, but when my wife drives for the school shuttle, running around doing short trips we average 10.5 -11lt/100 km and even higher.

I seem to manage closer to 9.5 - 10lt/100 km and on longer freeway runs between 8-9 lt/100 km. On a Sydney to Adelaide trip last year I was getting 8.1 -8.2 lt/100 which I thought was excellent, the car was loaded with gear but only me in it.

I put the difference in day to day fuel consumption down to the fact that my wife is always running late (due to the kids) and rushing from one thing to another.

Fuel use is highest getting the 2.5 t beast moving, so if you are slow and steady off the line and not punching it to get to the next set of light so you can do your hair and makeup you will find the consumption much lower :wasntme:

Regardless, your fuel consumption sounds very high so might be worthwhile getting a few thing checked.

The other major influencer is tyre pressures, check them regularly and make sure they are inflated to at least the psi noted on the trye placard or even a bit higher. I run mine closer to 40 psi.

Regards,

George

2 words you cheeky boys.... Constable Nasty!


Tunnelthug - I am using 95 Premium with the shop fitted Wrangler's on an 07 vehicle so there you have your economy! Maybe I should change to 98???

(And I double checked it this morning, it is actually averaging 17/100km since the service last week, so really, that's not that much better than the original 18/ 100.)

I forgot to mention that it is an automatic. Are you guys driving manuals? Presumably that might make a difference???

Apart from that, I will try and drive slower and take my shoes off :angel:.

Only picked up this thread now….. Fifi it would appear your D3 is very much on the thirsty side.

I get 16/17 around town (this used to be 19 when I lived in Sydney) and 11/12 on the highway. That was with the standard rubber and now with the Conti ATs. It worth noting that I don’t drive like an absolute hoon, but I also don’t drive sedately. I actually find my D3s fuel consumption a nice change…….. my D2 V8 used to use 22 around town and 15/17 on the highway……. Oh how I miss that car :) we won't even mention my RRC

With respect to fuel, I run on 95. I have mentioned this elsewhere before and I have run the numbers after a month of trials and the 98 doesn’t make financial sense. There is a marked difference in fuel consumption between 91 and 95, which justifies cost of running on 95. According to my calcs (and tests) the minor (and it is only minor) improvement in fuel consumption between 95 and 98 doesn’t warrant the cost of the 98. For what it is worth the user manual says anything 91 octane and above can be used, but recommends 95.

As a last point there are very few manual D3s around………

[WhiteD3]

Fifi,

Mine's an 07 V6 too. When I first got the car the economy round town was closer to 20:eek: I had to relearn how to drive to bring it down to 15.x.

But this is a combined cycle figure as I drive the suburbs and CBD along with the freeways, etc.

Gentle acceleration, never let it rev above 2800rpm (Max torque I think) and I get off the accelerator well before I need to stop. But like DiscoSaffa I'm not a sedate driver.

I also run 98 octane. Did the sums early on and found at least 2l/100km between 91 and 98 octane.

[FifiLámour]

Thanks, I will start watching the rpm gauge now.

I just rang Astral LR in Brisbane and spoke with Jarrad in the service dept. He reckons we should expect between 15 - 18litres per 100km suburban driving on the D3 with the V6 engine. This might include a little bit here or there on the motorway. And he commented that 18 was absolutely top of the range.

I have 2 months left on the warrantee so I have booked it in for them to check out the fuel pump etc. I know it can't be the air filter as that was just cleaned and I'm really not that much of a lead foot, I think.

So for the next week, till it goes in, I'll be watching it (and myself) like a hawke, LOL.

DiscoSaffa - I can see what you're saying - the cost benefit between 95 and 98 might not be there. 95/98 vs 91, yes, I could see that.

[trobbo]

I will have to respond to this from home cause I have a table showing indicated consumption v actual, cost of fuel, distance travelled, km per ltr, ltr per hundred, average km/p hour.

In general it is 13 - 14 ltrs per hundred with short city driving and 11 on highway.

[WhiteD3]

I have 2 months left on the warrantee....

Fifi, off subject but if you have 2 months to go and plan to keep the D3, then the Allianz extended warranty might be worth considering. See the threads on this in the D3 forum.

I got mine through Luke at SCLR.

Cheers.

DiscoSaffa - I can see what you're saying - the cost benefit between 95 and 98 might not be there. 95/98 vs 91, yes, I could see that.

Found my sums...... This was while I was in Sydney, so I noticed near enough 3l/100km improvement in fuel consumption from 91 to 95 (around town) between 95 and 98 it only improved by 0.2l/100km.

It is worth noting that all the figures I am quoting (and I suspect most others in the thread) are as per the computer. Fifi, if you are actually calculating your fuel consumption your quoted figures may not be so bad. The computer on the D3 has a reputation for being optimistic and under estimating fuel consumption..... If you are quoting the computer figures, it could be that you just have an accurate and honest computer..... :)

[trobbo]

If you are quoting the computer figures, it could be that you just have an accurate and honest computer..... :)

The variation between displayed and actual for TOD has varied by as much as about .8 ltrs per hundred to as little as .2 ltrs per hundred.
TOD is always optimistic but sometimes the difference is very minimal.

[FifiLámour]

It is worth noting that all the figures I am quoting (and I suspect most others in the thread) are as per the computer.

Yeah, I'm quoting the onboard computer.

WhiteD3, I didn't know about that extended warantee. Thanks, will go see if I can find the threads.

[vnx205]

It is worth noting that all the figures I am quoting (and I suspect most others in the thread) are as per the computer.

My figures for the Series III were not from the computer. :p

I often wonder how many people (with or without computers) bother to correct for odometer error. My Series III used to travel 107 km for every 100 km indicated. The Defender does 97 km for every 100 km indicated. People sometimes make a correction when they have strange tyres fitted, but even with standard tyres, most odometers seem to be a bit optimistic.

[Disomania]

OK, figures:

After loss of spreadsheet, here's figures for overall average only:

Distance L/100km MPG KM/L
7749.7km 10.29 27.45 9.71

For our Tassie trip:

Distance L/100km MPG KM/L
3777.1 10.32 27.36 9.68

Most times the OBC would say between 8.8l/100km and 9.9l/100km. Car is not accurate at all, but still VERY VERY good for a 2.5t vehicle.

[Dingmark Jim]

A big factor is what defines "suburban" conditions. I know that when we moved from Sydney to Perth our average speed (as per computer on another car) increased from 21km/hr to 32km/hr. I would have to think that a bit more steady suburban driving speeds will lower the consumption rate. Oddly, the V8 tends to have slightly lower consumption than the V6 petrol, but the savings would never pay for the difference in cost. The V8 is a pretty highly tuned motor, so the improvement on 98 RON fuel may be better than the V6.

The 50l/100km I quoted for the beach is probably the highest possible figure for the V8. It was a sand lesson for my (then) 21 yr old daughter. She was deliberately driving on the soft sand high up on the beach (she replied, "Because it's more fun" :D) and the sand was above the axles, AC was on full (this was WA in January) the radiator fan was on full roar - noiser than the engine, and the engine temperature was trying to drift into the "high" zone. It was indeed fun and I think the engine and chassis were finally being used at their design capacities for once. I'm looking forward to replicating this test with the 3.0 TDi next summer.

[trobbo]

As an update to this thread earlier this week I had an indicated average fuel consumption figure of 7.9 ltrs per hundred Km. :eek:

Highway driving on flat well made road. achieved with the standard tune. Stop start driving obviously has a significant impact on consumption given I usually get around 13 ltrs per hundred.

I was going to be happy if I could ever get 10 ltrs per hundred now I'm going to be dissapointed every time it goes over... :D

[Normthe1]

Fifi,

If I drive, I get around 10.5 l/100k however if SWMBO has the keys, she struggles to keep it below 11.5.

These are the computer figures by the way, I don't drive it enough to have my own...

These are around town figures...

[wyperfield]

I just came back from a trip to Lake Eyre. Melbourne to Hawker to Farrina Ruins to Andamooka to William Creek (for the 2 hour fly-over), then Halligan Bay, Maree, across the Cooper, Mungerannie and then back to Melbourne.
We did 4090 klms and a total usage of 11.5 l/100 on diesel - with a mixture of road, a bit of sand and many dirt roads with a loaded cargo area + roofrack with spare tyre and 40 litres of water/fuel.
Tyre pressures down to 28 psi on dirt, 40 on bitumen.

The best ever economy I have recorded was 7.3 l/100 on another highway trip with my learner daughter driving.
Cruising at 90 klm seems to give the best econony, but that makes it a slow trip. I would rather cruise at the speed limit and use more fuel.
I have also noticed that a strong headwind wind can make up to 3 l/100 difference.

VNX wouldn't that mean your speedo is out too then? How would you know if you were travelling at the speed limit?

Trobbo - that is an incredible figure! Are you driving a diesel?

Our best seems to be around 11 - 12l/100kms on the highway (with my husband driving, I might add ;)). But even then, it is hard to hold it on that for long. And that is with newly fitted Pirrelli Scorpions. School pickups and peak hour traffic will still drive mine up around 18 - 19l/100km.

[trobbo]

Hi Fifi, yes tdv6 hse. When I saw those figures coming up the rear view mirror sure did get a workout looking for a big mack truck.
Usually I sit around 13 or 14 ltrs per hundred with city driving.

[grumpa]

Hi
I have a D3 S 4L petrol. Fuel consumption around the city is awful. However, just got back from a 2,500km trip and achieved just over 12L/100km.

[Disco4SE]

Hi Fifi, I have the D4 3.0Lt Diesel and average 10.5 Lt per hundred with a mixture of driving (mainly around town).
On a trip, I have achieved as low as 8.0 Lt per 100.
Cheers, Craig

[rocmic]

I have 54531km at an average of 11.08 l/100km on a 2008 TDV6. Most of my driving is to and from work about 20 km of freeway (or car park - its the M4 in Sydney :() and about 10 km of suburban road each way.
Cheers

[Fluids]

You guys with TDV6 D3's should be really happy with your fuel consumption figures.

The best my auto Td5 D2a has done is 9L/100 .... worst (stockton beach) was 18L/100 ... around town (not city, coastal town) is about 11-13L/100 depending, and my long term average (over the last 18months - on/offroad combined) is 11.8L/100.

You guys are getting around the same or better, with an extra 25% worth of vehicle to drag around. Impressive!

... and I also get worse figures when SWMBO is driving :)

[FifiLámour]

Wow! The difference diesel makes is huge, isn't it? Has anyone done a comparison on the cost benefit of diesel versus petrol engine? It would be interesting to know how long it takes the petrol savings the diesel makes to pay for the addition $10,000 or whatever it cost. I think I've heard the diesel engine lasts longer too, is that right? And do they drive differently to the petrol version?

And what are us girlies doing that make our cars burn less efficiently? Is it because we all do the school and grocery runs so there's lots of idling around carparks while you boys do the highway driving? Or do we really drive differently? That is my next question :p.

[WhiteD3]

And what are us girlies doing that make our cars burn less efficiently?

I refuse to answer on the grounds I may incriminate myself:D

Hi Fifi,
Not sure how long it would take to make up the purchase price cost difference in fuel?
The diesel motor will last longer and your re-sale value will be alot higher. So I suppose the answer to your first query would be that the extra money you spend buying a diesel will be re-gained when you sell.
Re: Females using more fuel........here goes. My wife likes to drive flat out especially when the engine is cold. I drive gently until the engine has reached running temperature, and even then, accelerate gently from traffic lights, round a bouts etc. My darling wife thinks that you are meant to get to the speed limit in as quicker time as possible..........now that will use fuel.
The diesel Disco is a more relaxed drive compared to the petrol because of significantly more torque at lower engine revs. You dont have to pedal it as much to get it going.
My wife has a 3 series BMW diesel. She had the same vehicle / engine in a petrol for a whole day whilst hers was getting serviced. By the end of the day, she couldn't wait to get hers back.
In summary, those who have never driven a diesel are happy to stick with the petrol, whereas those who have diesels would never go back to a petrol.
Cheers, Craig

[Disomania]

Thought I'd put in an opinion as well - it's all the rage these days. My D4 uses an INDICATED 8.8l/100km and a calculated 10l/100km (average over 8000km) combined. This is in a D4 2.7.

As to the 10k greater cost, that's returned with much greater resale - when I was shopping for a D3/D4 it was usually around 6k more for a diesel with up to 40,000 more km on them, and if the km's were close, 10 - 12k more for the diesel. So, even with the stupidly higher cost of diesel over petrol, come sale time it will be a better equation than the purchase price indicates.

Still, from reading the starting post for this tread, I would think you should be able to get better than 15l/100km on the highway - I'd be carefully checking tyre pressure, alignment, and droping 10kph off the speed where it's not going to upset other drivers. To give an idea of how much you'll save by the 10kph slow down, many years ago I had an RB30 Patrol that would give 12l/100km at 100/110 on the highway, yet at a 90/100 run would do 9.8! 2l/100km saving while not adding too much extra to the trip - we cheated for that though on long trips by reducing the stops for the kids by half (where 30min stops down to 15min stops). Sometimes we got places faster (time, not speed).

Have to admit I'm a little dismayed at the D4 TDV6 2.7's economy compared to my D2 TD5 - sure the D4 is very comfy and goes a lot harder, but I sure miss knowing I can get 900km from a tank on a trip (albeit with a tad larger standard tank) I mean, 9.5L/100km!
Though it's around town where the D4 really finds ways to chew fuel compared to the D2...

Does anyone know if the diesels loosen up and/or improve their economy after a few thousand kms, or do we just learn to drive them more nicely?

[CaverD3]

Mine definately loosened up but the D3 will use more fuel than the D2 unless you drive carefully. But it is too tempting to use the extra grunt. :D

[HJF]

On my old (07) RRS TDV8 I was getting and 11.7 per hundred with 75000 k's on the clock. That number would move down a little if I did a long drive on the freeway. Have had it down to about 10.5 on a gold coast to the snow trip.
The new one is sitting at about 14.5 at present but I expect that will improve as the car has only done 1800 k's so far

[stig0000]

tdv8 will easly get into the 9s, around town easy 10, the best iv seen out of a tdv8 was 7.8 the other week, :o:o

they just use there power so well, so lazy and down low,

yet to see how a 4.4tdv8 gose tho, :D

It sounds like one issue could be fuel, if using 98 octane it will benefit definately, also it will have to be used over a period of time, not just the 1st tank.
That will give you a bit more grunt and hopefully you use the throttle less.
Which brings me to the next point, try taking off smoothly and plan your driving inadvance. Slow down earlier if approaching tarffic and or lights etc.
Coast to them as the fuel is shut off on coast. You are sitting up nice and high so use that to your advantage and plan ahead. when resuming from your coasting which also has be done in gear, never select neutral, press down slowly and know how much to accelerate as too much will be a waste as you just need to brake again.
Also, see if you have the air-con ON or OFF?
Air con will chew up more fuel, if its a nice day, just put natural venting on or open a window, can make up another 5% easily.
Last but not least, check tyre pressures as recommended by your tyre dealer or your handover book.
My wifes friend ran hers on 60psi which was crazy and I told her that but she swore that it gave her better economy. That was till one just exploded on a hot day at a supermarket car park.
Everyone thought there was a shot fired.
All the other tyres were badly worn in the centre and are also stuffed. False economy in other words plus dangerous.

Wheel alignment is another beauty but throttle control and knowing how things work and why is biggest culprit.

Save driving and have a great day.;)

Hi all,

My 350km old D4 2.7 is currently sitting on 11lts per 100 around town with no freeway work. It had 35.8lts per 100 when I picked it up!!

Mind you I seam to be driving it like a grandma atm due to I guess running her in, or it maybe due to the fact that it is my first ever auto - never thought that day would come!! :eek:

I'm hoping that 11 around town will be the norm an 9-10 on the open road. It will be interesting to see what the 265/70/17's will do to economy ;)

Phil, if you are using computer read out, I think you will find it optimistic to the tune of about 1.5l\100k :o

cheers ken

[640Newton]

In our 2008 TDV8 I use about 10.5L/100km doing the daily commute into Sydney CBD. On long trips with freeway driving I use about 7.8L/100km.

[OzAd4x4]

I am reading that figure off my ScanGaugeII however the computer read out is very close....

my D4 3.0 with 8000km under it's belt seems to be getting similar fuel usage to when I got it new. some examples of what I've experienced:

country driving at 110km/h : 9.0 l/100 km
hard country driving at 130 mm/h with a 1t trailer : 9.5 l/100 km
inner CBD driving with a heavy right foot : 11.7 l/100 km

I agree with one of the posters the real world usage is about 1 l/100 km more than what the computer shows.

I should note that both my wife and I drive it hard - my wife more so than me :)

[kenl]

The computer is optomistic for sure, using a Faultmate MSV-2 you can check the CCF (car configuration file) and there is an option to change the dash readout for fuel economy on my MY10 3.0 D4. The setting was +7% which was about what it was optomistic by since new. I set it to 0% but it didn't seem to change much I now have it at -7% and it's showing about 11.4 L/Km.. which is about right based on real calculations, I do drive it hard though and tow trailers often..

bugger, cant cut and paste from excel and it wont accept spaces or anything else to format.



trobbo, depending on your version of Excel, you can create a picture. The image below was done in ver 2007 but basically can be done in all versions of MS Excel from V3 on.

A little known feature of Excel is the Camera. Search on it in the Help system or simply customise the Toolbars by adding the Camera option.

You still have to manipulate the image through you favourite image editing tool (I use Paint Shop Pro) and save it as a JPG, GIF, PNG, etc. image type before you can display it in AULRO website.

Just finished my first tank in my RRS - Melbourne to Canberra at 110kph and then about 150km around town in Canberra. Computer said 8.8l/100km but actual was 9.9l.100km, so the usual under read by about 1l/100km would seem about right.

Gary, 'Spose you will be testing the fuel consumption travelling to the LRC-ACT meeting on Monday night ... must be a little better than the 101!

[Duck's Guts]

D4 2.7TD fuel records across it's 14,750km life say 11.50 l/100kms average.
Mostly country driving. Includes some infequent short distance box trailer towing, and ~1500km 2t caravan towing (averaged 14.81 l/100kms).
So without the c/van, average becomes 11.24 l/100kms.

[Jesse B]

Just come back from about 800 km trip towing my camper trailer (most likely about 1200 kg on the road) with my D4 3.0 which has done about 32,000 km - averaged 14.5 / 100 km. Of the total distance about 700 km was at around 100 kph and the rest grinding along pretty slowly with a bit of up and down on some rough bush tracks.

In general road use I'm not getting the same figures as others are reporting for the 3 litre motor - highway driving (110-115 kph) with cruise set most of the time gives me around 11 / 100 km real consumption, with the computer the usual 10% under that.

[Mully]

Just read through this thread and thought it worth adding that my 2005 D3 Diesel HSE (with loads of extra weight) regularly got around 11.8 to 12 per 100 according to the on board poota.

I recently got the very problematic auto serviced and modded (for filter changes) and she has dropped now to around 10.2 per 100 consistently which is quite a difference post auto service.

These figures are around town.. highway trips are always under 10 per 100 depending on conditions.... 8.6 to 9's being typical.

...do still miss however the ever reliable 900/tank the TD5 always got. :(

Cheers.

Hi all,
Just returned home from a week away boating.
Vehicle being a D4 3.0Lt, boat with gear around 2.2 ton.
I did the same trip last year with only 1,200Klm's on my D4. The only difference is that I now have a OL bullbar and Pirelli ATR's.
Last year I averaged 13.1 Lt per 100 Klm's up and back.
This year I averaged 14.4 Lt per 100 Klm's on the way there (sitting between 115 Kph & 120 Kph......GPS readings).
On the way home I sat on 105 Kph and used 13.4 Lt per 100 Klm's.

Cheers, Craig

[Africampers]

Hi, with my D3 V8 HSE to work in back in Sydney traffic I get 16 l / 100km with the aircon on Ecom mode - and 18.5 l / 100km with the aircon at 22 degrees. Highway travel with a/c is about 12.2. But when you start using the V8 in earnest it's a different story. Towing my off-road Conqueror Commander caravan over Googs Track in the middle of summer with very loose sand - I averaged 50l / 100km. Fortunately Googs is less than 200km - but well worth every litre of fuel.

[Jesse B]

Recently come back from a long highway trip, mostly at around 110-115 kph, aircon set to 20 degrees (and on the whole time), some idling with aircon on (it is mid-summer!) while taking notes etc for work. Traveled a total of 1947 km and used 221.5 litres for a trip average of 11.37 per hundred. This is in my 3.0 D4, 33,000 km on the clock, with OL bar & LR raised air intake, but no other bits hanging off it and little load on board. I drive pretty conservatively - and I remain disappointed with this kind of result. I have never been under 10 litres per hundred, and rarely get much under 11 :(.

A question that occurred to me late in this particular trip - I wonder if the odometer is inaccurate? We all know about the computer read-outs being over-optimistic, and I think most D4s have a similarly incorrect speedo reading - to be doing a real 110 kph (by GPS) I need to sit on an indicated speed of about 115. So, I wonder if this 1947 km of mine might actually be incorrect too? Anyone checked this out? Next time I do a long haul I'll check mine against the highway distance signs over a couple of hundred k's.

[101RRS]

A lot of people have been saying that the 3.0 is more economical than the 2.7 but posts of actual usage seem to indicate otherwise.

What makes some think the 3.0 is more economical than the 2.7?

Garry

[Jesse B]

The official test figures suggested the 3.0 would be about 0.5 / 100 better on average than the 2.7. But like you, I've not seen this coming through in the majority of posts. Some seem to be getting really good figures - well down into the 9s - but others are all over the shop. Indeed, the main thing I've noticed is how much the figures coming in for the 3.0 vary - I know people drive differently, but I don't think this explains the consistent and significant gaps between results in apparently similar driving circumstances. Can't all be down to percentages of lead in the feet, can it?

[Disco4SE]

My D3 2.7Lt was slightly better on the fuel (on a trip) than my current D4 3.0Lt, however when towing the D4 is noticebly better.
Around town, they are much the same.
Cheers, Craig

[DanW]

I have a 2.7 TDV6 D3, and I got an app for my iphone and started recording back in August. On a ~3000km round trip Brisbane to Thredbo it averaged 8.2L/100km (even though the disco reckoned it was doing a lot better than that reading 7.4).

Around town I average about 11L/100km (Disco says about 10), mind you I do drive it pretty conservatively around town.

Interestingly the figures are pretty much the same as my Mazda SP23 - but obviously I put ULP in that, and I could never claim to have driven that conservatively which the tyrepower guy can attest to. Let's just say I don't get too many KM's out of tyres or brake pads..... ;)

[outbacktourer]

Just done Sydney to Mackay rtn loaded, normal highway speed. Indicated average was 9.3 - D4 TDV6 3.0 HSE

Yeah, went thrugh some water on the way up inland. Up to the bonnet in Chinchilla, after we diverted at miles (road closed at Theodore) the road closed behind us. Got back over the Fizroy with 2 days to spare. Cerainly is some water around that's for sure.
