what kind of k's??....fast ones I reckon :-)

I guess you mean fuel consumption. About 18L/100k (highway).

and well into the twenties off road. Between 22 and 26 L/100k depending how hard you work it.

If I've misunderstood your post and you are asking how many k's you would typically get out of the engine then thats really hard to say-depends on how well it has been looked after. Around the 140 to 160 mark they will need head gaskets and welch plugs and water pump and such usually. The radiator is the biggest bugbear. If it hasn't been flushed annually you'd be best to get a new core, or at least get it rodded. They will run forever but get pretty tired once the cam and followers wear, so will be down on power.

Hope that helps.

That’s consumption’s not too impressive out of only a 4.0 V8, would of thought it would have been a chit load better than that.

Drive it conservatively on the highway and you may get 16L/100k. But it isn't exactly a light vehicle, and a 4L V8 maybe a pretty small engine but it is a big car, so it works pretty hard.

Pretty similar consumption to any comparable petrol 4wd of the same era really.

I get around 12 or so Ltrs per 100 out on the Hwy sitting on 110-120kp/h and 14-15 around the city. That’s out of a 4.0Ltr V6.

I Thought the V8 Disco's would do a little better than 18Ltrs/100, but guess not.

I had on very rare occasions got 14L/100k. But on my various long travels, all around 10,000 k, I averaged 19L/100k with the roof rack on.

G'day Exploder,

Is yours full time 4x4? The disco is driving all wheels all the time - no option for 2 wd - no hubs to lock/unlock That may be the biggest contributing factor in the difference.

Also as David has pointed out they are a pretty heavy vehicle. And slightly less areodynamic that the average house brick!..;-)

Cheers, Mark

No it has 3 modes Auto, 4Hi and 4Low, for normal driving it’s in Auto mode witch activates the TOD system, so in normal driving it’s 2WD until slip is detected at the rear then the front axle will be engaged until traction is regained then it will go back into 2WD mode the Hubs are permanently locked in.

I have herd stories about people putting them on a 2 wheel Dyno and as soon as they start the TOD system detects a speed difference between the front and rear wheels thro sensors in the T/Case and ABS sensors in the Wheels and engages the front axle, now that would be interesting LOL.

It a 98 Explorer by the way, thus the screen name, and no explosion yet LOL.

Hi stormbay, for all things Landy, try the AULRO site.

They are a pretty good bunch and are always happy to give you any info, good and bad, on anything Landy.

Cheers

G'day John,

As you have already been told the 4.0 V8 2000 Disco is a pretty thirsty beast... I have one.

It really depends on how you drive.

Around Melbourne I have to do a lot of short trips ( I only work 9 Km for home). They run pretty rich on startup (computer controlled so there is not much you can do to change that). This combined with the fact I tend to be a bit heavy on the right foot sees 19 -20 Ltr/100Km constantly around town.

Highway - again depend how you drive... If I am careful I get 14 - 15 ltr/100km - cruising around 90 - 100. If I push it harder and sit around 110+ that goes up to around 17.

Off road I have never had it get worse than 22 l/100k ...

Pulling my Tambo camper fully loaded through the High Country I was getting 20 ltr/100 k... car and trailer weighed in at 3.5 tonne... so I wasn't too disappointed with that.

My best piece of advice if you are looking at one is SERVICE HISTORY.. get one that has been maintained well and it will be a good car... even if it's a bit thirsty.

Get one that has NOT beeen maintained... and you are likely to be the target of all the Landy bashers that tell you how unreliable all Land Rovers are... ( mine has never failed to get me home)

Finally for those wondering why they go through a fair amount of fuel.... one contributing reason is that they are full time 4x4... so you are ALWAYS driving all 4 wheels.. that has advantaged... but it doesn't help with fuel economy.

Hope that helps,
Mark

Thanks Mark and everyone else for their replies...
Having said that and heard the facts I guess it's back to the drawing board! I live in Tasmania where the fuel is getting in the mid $1.30's and used diesal 4x4's are getting more expensive by the day. Same old situation, more money to buy a diesal or less for a petrol rig and then pay more for fuel. "If I ruled the world..." I wouldn't worry, buy a new Disco and relax... not even sure why I want a disco except I've found a really good Rover mechanic!! Does that make any sense!

We are aiming to drive the Tribulation track this year so it is kinda important what we depend on.

Cheers
John

No worries John,

I know this will draw flack.. but of course it makes sense to want a disco..;-)

Anyway... I know Diesel is a more per litre in Tas.... but the diesel Disco's get MUCH better economy.. My mate that has a similar are disco TD5 to my v8 get the sorts of figure below....

Around town... V8 450km a tank........... TD5 700 km per tank

Highway V8 550-600km per tank TD5 1100 + per tank

So maybe a closer look at a diesel may be a better option. That way you get the Disco you want... plus better running costs. I know servicing the diesel is a bit more... but I am not sure how much.

As driveline said... pop in to www.aulro.com great site based in aus... thousands of Landie fans that can give you their knowledge and help if you want it.

Good luck with it.. Mark

PS. I did a quick trip to TAS a few weeks ago... did Devonport, through Cradle Mountain to Straun.. played on the beach there a little then Straun to Hobart - Hobart to Devonport and the Disco V8 sat on a contant 600 km per tank... FYI

My '79 Rangie (3.5 with Zeniths) used to get me 7.5-8.0Km/l on the highway...back when it was being used!

I had to get the front drive shaft checked/balanced/repaired and had to drive the beast as a RWD for nearly a week, and it seemed to make no difference to the economy!
Mind you I was a bit more gentle with in in that time.....but I definitely saw no difference in economy...(OK maybe .01km/l saving!!)

While this is not a definitive test...I never believed the rumors of higher fuel consumption with a constant 4WD!

Engine condition/tune, tyres, loaded weight, fitted accessories, right foot, and driver attitude will affect fuel consumption more than the old "4WD/2WD" argument.

just my view on that subject!
