14.0L/100km around-town

[LiamO]

Just wondering if my 2.7-litre Disco 4 fuel consumption of 14.0L/100km around-town driving is a bit high? No harsh acceleration just normal Sydney grid-lock driving..

[Geedublya]

Similar to what I got with my D3, however it had front and rear bars and a long range tank. It may be worthwhile getting the gearbox software updated as this helped Redback's fuel economy.

Currently I'm getting about 18l/100 it is 5.0 though.

[letherm]

It could also be how you drive, in the sense that if you do a lot of short trips you will get worse mileage (or is it kilometreage ???? these days). I've got a Pajero (new Discovery D4 HSE being picked up on Thursday:D) and usually get 20 litres per 100km. We do a majority of very short trips. If I go on a longer drive the fuel consumption drops dramatically. So constant grid lock travel may be the reason but I think it's still worth checking out.

It'd have to be the gridlock doing it. My usual drive to work and back is 100km round trip, 15% stop start, 15% free flowing 60km/h, 30% freeway 110kmh and 30% country b-roads.

Get 9.5-10 L/100km - RRS 2.7TDV6.

[Redback]

Our 2.7l D4s economy was terrible when we first got ours, getting 12 to 14l/100 too and from work, 16 to 20l/100 towing, with no accessories at that stage, surprisingly when we did get the accessories fitted it didn't go up that much, repeated approaches to the Dealer made no difference, apparently that's normal:mad:

On a trip to Sth Aust we were getting faults and going into limp mode, so a quick visit to Lincoln Land Rover to see what the issue was, after a quick drive he decided that he would re-flash the ECU, do the latest software updates and put in the latest 3.0l gearbox updates, now we consistently get around 11 to12l/100k too and from work and 13 to 15l/100k towing.

All good now, I wish all dealers were like Lincoln Land Rover, nothing was a problem, a real nice bloke to boot and looking at all the old series Landys and Rangies I would say an enthusiast as well.

Yep, that isn't ridiculous.

Before the recent software update and with the M/T's I was getting 12-14 in and around the city

Now it is back to reading 10 which i believe is abut 11 with the update done. And no more dreaded shudder/clunk in the gearbox down low.

[SimmAus]

My D4 2.7 averages around 10.5. - 11.0 in Sydney, although no gridlock traffic, and only the occasional highway run.

[WhiteD3]

My D4 2.7 sits on 10.4 on the carputer which is 11.2 in real life. My Mrs can make it go up by 2L/100km as I can make her Golf go down by the same amount. Driving style is a big factor.

Driving a D3 4 litre for 4 years gave me the opportunity to refine by driving style :D

Something strange happened to mine.
Couldn't get less than actual 10.5's no matter how hard i tried on a run.Around town under 12.5's was also difficult.

Start long trip,7.5K in four weeks,including desert crossing.Beginning of trip,11 to 11.5's,clocked many tanks,all around the same.Loaded with stuff on roof as well.
Last two tanks of trip started getting low 10's,vehicle loaded identicle to start of trip.

A week after coming home had to do two trips to Grafton,600k's round trip each time.It got just under 9.4l/100 on both trips.I wasn't driving for economy either.Lightly loaded nothing on roof.

No trips to dealer,still can't work out what changed the fuel use?

The vehicle had just hit 24K,but i don't think that is the answer.

Maybe something changed in the electronics,engine or G/Box ECU maybe.

[Meken]

Your engine has just started to run in ;)

How many k's did yours have on it went to Lincoln LR.

Just thinking the k's may have something to do with it as well?

[LiamO]

BTW - Gas Manager is a pretty good app to help track fuel consumption and is available for both Android and iOS – Free

Almost 50,000ks, has been a fuel gussler from day one, yes the accessories do have a bit to do with it, I knew this, but when your getting the economy of someone towing a big van when your not towing, I think even the dumbest person would know there is something wrong, thankfully we found a Land Rover Dealer where they actually knew what they were doing.

Thanks for that. Have just downloaded - looks better and easier than my spreadsheet.

I agree with comments that economy of the D4 improves with age, at least up to about 50,000km. I used to get 11/12 litres per 100km around Perth, but now consistently averaging around 10 and sometimes even lower.

The recent run across to Tassie and back seems to have made a bit of a difference - economy now looks to be better both in the city and also on long highway runs (and that was with all seats down, a fair load in the back and a decent load on a full length roofrack while travelling as well.

I used to think that the D4 was not as economical as my Td5 D2 - but that has now changed. Very happy with the economy that I'm getting now, especially when you consider the size and weight of the vehicle.

Was in Lincoln on the way home a couple of weeks ago Baz and saw the LR dealer there - didn't have any need to drop in though. We stayed one night in Lincoln, followed by another four at Coffin Bay. Was actually surprised to see LR dealerships in country towns over in SA (saw one in Kingston SE as well) - it's not something that we have over here in the West (other than Albany). The rest of the country dealerships closed down years ago.

Road Trip is another good one.

When threads like this come up I always put a plug in for www.fuelly.com (http://www.fuelly.com) which is an online fuel consumption data managing site but it is public so you can compare to similar vehicles. (no association I just like to see what others are getting in fuel consumption) It's sort of like Facebook for fuel economy anoraks.

As said,mine was also a fuel guzzler until about 24k,in fact it was way worse than the D2a.
i still can't believe the change,in fact it is very noticeable how much further it goes with every tank full.
It has just a bar, cargo barrier,traxide dual battery kit,and two roof rails.In fact on the scales it is exactly 2.7T with driver and 3/4 of a tank of fuel.

I still don't think it needs this sort of mileage to 'run in',but i am no mechanic.

I have been questioning whether my fuel usage is ok or not, but hearing others I am concerned.

3.0l 80% city, 20% FWY
Getting 550k’s out of a tank
80% hwy getting 620k out of a tank.

Car has done 13,575klms.

When I am filling the tank most I have put in is 68litres, normally 64-64 litres.

Tracking via Fuel manager has me at 13.0L per 100 car says 11-11.5l per 100

Getting 7.7Klm’s per litre.

Should I be looking into this? Cannot trust the dash readout. When on freeway I can get the consumption down to 8.0l per 100 which is more like 9.5 in real terms. City seems to be 11-12 on the dash readout so about 13.5.

Thanks

Sounds pretty much the same as mine (13MY SDV6 @ 27000km).

All my fuel calcs tell me this is more economical than my D3 was, but I don't seem to get as far between fills in the D4.

Cheers,
Jon

Your fuel consumption sounds pretty good. With my short trips to and from work (probably 3km each way), in heavy traffic, i get around 15l/100lm especially with Christmas shoppers around Chatswood.

If I happen to do a longer trip on the weekend, it almost immediately drops down to 12l/100km.

Haven't had time to do a really long trip yet; the Lithgow weekend was around 11l/100km.

FWIW, this is with a corrected readout, after calibrating to Road Trip over 6 tanks full.

[Plane Fixer]

So far with the fuel tracked since new (53000) I have an average of 11.10l/100. I have got down to 9.0 but it has been exceptional.
Have just come back from Adelaide and have been sitting at the top range of nearly legal speeds and have got high 10s and low 11s. I am not driving for economy and are quite pleased with the overall economy as with a 3.0l Patrol previously and an average of 13/100 the D4 with the exceptional comfort, power and sheer driveability comes out on top every time.
The permagrin has not faded simply enhanced!!!

That's pretty good.

My average is sitting at 13.7/100 (using a logbook app....trip computer shows average at 11.4) since new....47000. I do a bit of towing though.

A recent 1300km round trip to Kalbarri saw 12.8 (trip computer showed 10.5).....that's without a trailer, but mostly highway.

I have never been pleased with my D4 economy, compared to my Touareg (same trip saw 8.9/100) but really do like driving the D4, and of course it's slightly heavier and aerodynamic as a brick.

Brett....

[Plane Fixer]

If we want economy we take the Golf 2.0 TDI but the wife opposed the D4 initially (all that money for a car) and now loves it to bits.
I run an excell spreadsheet on both cars, which we bought new, and acts as trend monitoring for both vehicles. (6 spd)

[WhiteD3]

I use gas manager. This year to date over 18,000 kms I've averaged 11.2. 90% city/suburbs use.

[kero]

Could you blokes talking about fuel ecomony please say if driving a 6 or a 8 speed. Thanks Kero

[phl]

It's amazing the difference a longer run makes.

Filled it up today in St Ives about 11:30 (to give you an idea of traffic), drove down to Randwick via Epping Rd (Chatswood and Saturday mid-day = worse jam than peak hour), and got 9.3l/100km.

The previous tank average was 15.3l/100km, but didn't do any long trips, with all trips in peak hour. Huge difference.

I've just updated my fuel usage and can tell you the following:

Now done 30k.

Total average fuel usage 11 l/100km compared to about 11.5 for the D3.

Highway 10 to 11.5 loaded with roof rack.

Around town 11 to 13.

Towing 15 l/100km.

Off-road usually 12 to 15. Worst so far 17 l/100km.

Biggest fill 66l.
Longest distance travelled between fills 674km.
Best figure 9.6 l/100km.

Jon
