Hi all just looking at buying my first land rover discover and am looking at a v8 on gas just wanting to know how many liters of gas per 100 or a rough guide. So i can see what sort distance i can get from it. Gas is new to me just love v8's

Typically between 20 to 25 litres per 100km but it can be better or worse depending on how it is driven, how well the gas mixture is controlled (electronic mixture control or not) , how it is tuned, and how much external junk you have screwed to the truck. Roofracks, bullbars and big tyres all add considerably to consumption.

Kool thanks just wasent sure I defiantly like the power of the 8 over the diesel I knew it would depend on a lot of.factors 25 liters I can live withare the 4.6 in the rangie better on or worse for putting around in my experience in ford world it should be

My freshly rebuilt 3.9 V8 in a Disco 1 returns 20 to 22 litres per hundred. It was about the same before the rebuild but it makes better power for the same economy and is much better when towing than it was.

A high compression 4.6 with a gas cam would run rings around a stock, worn 3.9. If it's done properly it will be better conumption too.

Out of interest what is the best system to fit to a 3.9? and what is the best size under body tanks you can buy without hanging down to low?
I am thinking of going to gas.

Best always depends on the competence of your chosen fitter. I make up my own kits as there isn't a commercial kit available that has all the elements I demand. I won't go into length here, once you have found a fitter in your area, pm me if you have any specific requests.

As for gas tanks, two small 35 litre tanks fitted to the petrol tank location are the only decent way of converting these. You will have approx. 70 litres of LPG and whatever petrol capacity you can get in an auxiliary tank. In this day and age I would suggest contacting wreckers yards, especially in Melbourne as this stuff is too expensive to justify buying new if good second hand parts can be had for a fraction of the price.

Hi mate, I have an 01 d2 v8 Thor, on long trips to the farm I get 12.3L/100 normal driving I get slightly higher but still under 13L/100, I've been told by many now this is exceptional and isn't typical, last week I got a 13.4L/100 but I was doin a lot of dirt road driving and about 10-15 km in low range, I leave for jervis bay tomorrow towing my 14ft boat so when I get there I will post my km and how many litres I used to get there, mind you due to the tiny tiny wheels on my trailer I will only be sitting 80-90kmh so hopefully this will off set me towing my boat and my economy will be about 12.8L/100 I'm guessing so we will see how good of a guess I am lol or arnt hahahaha

Is that LPG or Petrol?? Petrol is usually a lot better l/100km than LPG

I have a BRC Sequent Plug and Drive system - fitted very recently. I get 18.5-19 at the moment but it might get better - around town. Manual V8.

umm i dont wanna sound silly but what is it? something for the ecu?

Your ok mate - no its a sequential LPG injection system made by BRC-Impco. It runs an injector for each cylinder and just copies what the petrol ECU does and adapts it...result. Cant tell its on LPG save for a torque increase at low revs. An in terms of economy its very good and I was told mine will improve over a period of 5,000klm to the point where it is very nearly the same as petrol - ie in my case about 16l/100k for Petrol at least. When it changes from petrol to LPG it does so seamlessly - cannot tell. When the pressure gets too low in the LPG tank it changes to petrol seamlessly.

Cheers

are you sitting down disco2_dan?
same setup as ozscott--
towing a 1800kg van I get 4KPL,, no thats NOT a typo.
I probably have the least powerful 4L ever made (my green one would run rings around this) but this is still amazing,,
If you are going to tow anything large, look for a 4.6 or TD5,, I reckon for 2ton around 400nm,,
The Td5 manuals have the lowest 4th,,
V8 auto's the tallest.

We get a terrific 30l/100k in the 101 on gas:D but is fun to drive:twisted:

Anyone know of a good carby place near us, when we got the 101 it was on total gas, we have now added a petrol tank and need the carbys tweeked:)

Haha... Just read my BRC manual and I was supposed to run it on petrol as much as possible for the first 1000k...so the LPG computer can learn I suppose... Better change to petrol and run tank and 3/4 or so through her. I bet my LPG l/100k will come down after.
:)
Pedro that sounds like cheap $ per 100k towing... Nice. I've not towed with LPG on the new system yet for any great distance.

On my old system - single point mixer style I was getting about 20l/100k on LPG versus 15-16 petrol in like conditions.

Cheers

after seeing the lpg prices in tassie while on holiday there last week, it almost doesn't seem worth converting to gas! 88-90c per liter!

ozscott

On the new system it is...very very close to petrol L per 100k...so it ends up being cheaper than a TD5 to run, even accepting the best figures posted up on this site for the TD.

D1 3.9 manual with a standard draw through mixer sees me get a pretty consistent 20L/100km.

I do have a lift, snorkel and bull bar making it less slick on the wind resistance front. I also run the internal scuba tanks for 50 useable L and preserving full petrol capacity.

Ok I filled my tank up this morning and calculated that I did 12.68L/100 so like I said I was sitting on 80-90kph nearly all the trip

i dont have an issue with what i paided i got it for 5500 and it has 210000 klms on it it has 2 small issues the drivers side exhaust has a leak between the manifold and the exhust and the front roters need machining. new pads allround 50% tread on the Pirelli Scorpions ATR's wear mark on drivers seat. a good buff and polish and it will be 100% better

I just did a run from Bundy across to the Wondai area (via Maryborough) in the wife's D1. Sat on 98-102 on cruise most of the way until it ran out of gas at 308kms. I then put 51.2 lts back in it. That works out at 16.6 lt/100km.

The Disco is a 96 3.9 auto with 175,000 Ks on it. Standard wheels/tyres/ride height, A/C off, drivers window down and all but empty except for me and a stupid roof basket I forgot to takeoff before I left.
