A UK persons perspective on LPG vehicles
We've had 4 LPG powered vehicles over the past 7yrs or so:
Jeep Cherokee - 4ltr 6cylinder, boot mounted 100ltr tank
Vauxhall Cavalier - 1.8ltr 4cylinder, boot mounted 100ltr tank
2 x Discovery 300 series - 3.9ltr V8, underslung tanks
All purchased with conversions already done - but have had quotes for a D3 V8 to be converted of around GBP2500.
D3 conversion replaced spare wheel with a donut type tank - meaning no loss of boot space - multipoint sequencial system.
Although we don't get the V6 D3's over here, i'd say that there shouldn't be an issue in getting a conversion done, just make sure it's a multipoint system rather than a single point mixer type.
Only issue we've had with ours was back-firing through the airfilter box due to letting tank run empty (single point systems tend to be prone to this - multipoints are ok)
And the Disco's having the odd tendancy to cut-out if the weather was cold and we'd switched over to LPG to early - this seems to be an issue with the V8 hating cold weather rather than an issue with the LPG.
We would of preferred to go for a V8 D3 rather than a Diesel (V8 fan main reason), but at the time of purchase we didn't have the cash available to add an LPG conversion after purchasing the D3.

No problem Neil
One thing I forgot to mention is that LPG tank capacities are only fillable to appx 80% to allow for expansion, so for example one of our D1's had two 45ltr torpedo tanks (one either side of sills) total capacity was 90ltrs or so. We could get appx 72ltr-76ltrs max depending on how cold it was outside (colder it is, more dense LPG is, more in tank i understand).
We were getting between 11-13MPG on LPG on short round town runs, and managed 17-19MPG on long motorway runs. I believe the V8 in the D3 is more economical (ha, never thought i'd type that - V8, economical ) than the older 3.9ltr one, so assume the V6 to be close to it.

The 4l V6 does 24mpg at 65mph ...... this goes down to 18mpg in stop/start town traffic.
Can get 27mpg at 50mph'ish on country roads around here. Running 44psi all around helps too ! .

Neal, I take it the D3 conversion si effectively dual fuel then? Runs on petrol from main tank and LPG from auxiliary and selectable?
Do you know of any reputable, certified installers of conversion specialists in UK?
Planning to import my V8 D3 from Middle East at end of contract here - LPG conversion would be the ONLY way I could afford to run it in Europe!

You'll have to GoogleUK to find something back home ...... LPG conversions of old
Range Rovers are quite common.There should be plenty of companies around for direct-injection LPG. .

rhffgb - there are plenty of LPg installers around the UK.
I've had quotes for a D3 V8 conversion from a couple based around west yorkshire way, prices were around £2500 or so max for a top spec multipoint injection system.
It depends on were you are located

Hello from John (Italy).
A few words to tell you that I have fitted LPG system on my 2005 V8 HSE (with an Italian brand - BRC-equipment).
I have run 40.000 Kms on it, have done both town and country use, Fast motorway, and also hard offroad.
As I live in the Alps, I have had MANY trips in a range from 2.000 mts a.s.l. to a maximum of 3.000 mts (the highest point I can reach here.
NO PROBLEM at all.
A proper fitting is a MUST. and I just tell you that I cannot feel if I am running on petrol or LPG, if I don't see the green light on the main switch (which is of course fully automatic).
Let's talk about fuel. My V8 would cost me a fortune. On LPG I have a 5% less of road traveled, but half the cost.
Downside: the tank (which is outside, spare wheel place) is not very large (about 50 litres), range about 300Kms. (I know that in UK someone would fit a 96 litres tank, but that is just good for road use, as the tank is too big and would affect the exit in offroad.
The good thing is I can do offroad with a good neat exit angle (the tank is even smaller than the 19" spare wheel).
The spare wheel is now on the back, I have mounted myself a neat RASTA wheel carrier (which is quite similar to the Kaymar one, but it is not necessay to replace the LR3 bumper...
I just can tell you that the engine is just smoother than petrol, and I can also take tha advantage of using the car even in polluted days (when a brand new petrol or DPF diesel would also be blocked) .
LPG has the right to move freely just as electrical, hybrid. I don't think this is a BIG problem in your country, but you can imagine how much it can be in Europe.
Hoping you can find this infos useful, a big CIAO to you and your beautiful country (I visited Australia and N.Z. in 1996...).
best regards

Nice post John
Would like to re-iterate Johns words regarding a decent installation. A multipoint system is a must, don't even think of scrimping by getting a single-point mixer unit installed - it needs to be the multipoint al the way

As Gary said, don't even think about the cheaper old fashioned mixer type .
That's like on a petrol engine, pulling off the petrol injection, and fitting a carburettor .
If you're going to do it, go for the modern Sequential Vapour Injection type .
More power, better economy, lower pollution, and no backfires .
And,here in Australia,they are now just starting to install the next generation of LPG, Liquid Injection .
More power and torque than the petrol engine .
Unfortunately, they are concentrating on their obvious main market, Falcons and Commodores, and wont be doing other cars for a while . Probably 6 months time .
So depends on whether you want to do it now, or whether you can wait .
John ( Italy )
What do you mean by " the advantage of using the car even in polluted days " ?
Cheers John

To Johnc18...
In Italy we have high pollution in large towns. In Autumn and winter it happens that private cars are blocked to reduce carbon monoxyde.
Only electric, hybrid and LPG cars can travel freely. This means that, no matter how young your car can be, diesel or petrol, it will be blocked.
Travel LPG and you can go as you please. That's why many people choose LPG.
Not second to the cost of it: and this is LPG costs 0,70 Euros per litre, vs 1,50-1,55 for diesel and petrol.
Have a nice day!

Hi All,
I have run a single point LPG (dual fuel) sysrtem in my 85 Range Rover (3.5 carbs, ZF 4 speed auto) for over 100,000 km without any troubles. Fuel burn on old carbs averaged around 14 ltr/100 km and on gas increased to 17-18 litres/100 km.
We have just had our 93 Range Rover 3.9 manual converted to sequential gas injection by Hunter Gas Technologies in NSW. Average petrol consumption over the past 80,000 km has averaged 15.1 litres/100 km which has included a heap of sand and other off-road driving.
My average injected lpg consumption over the past 1000 km has been 17.4 litres/100 km. Torque is impessive and its hard to pick which fuel its running on when cruising the highway.
It uses an IMPCO system that piggy backs onto the car's standard computer. A tuning program is available to enable drivers to 'tune on the go' using a laptop.
The vehicle starts on petrol and after a few minutes of driving automatically switches to gas although an override switch is fitted that enables either fuel to be burned. The switch over is instantaneous.
My work D3 is on diesel so will not be converted although a dieselgas conversion is available.
I believe that Land Rover will not warrant an aftermarket gas system.
Regards,
Bunta B
