A lot of issues to discuss.

Up front, you won't recover many $ on a 3 door Disco 1 although you can often find 4 door D1 with gas for not many K$.

I run non-sequential LPG on my 4.6 RRc, I lose about 7% of power when running on LPG. You can have after ECU modules fitted that change the distributor setting when running on LPG, this overcomes the problems when you don't have a dual map ECU. I get within 1lt/100Km of my petrol economy on LPG

The back-firing of Rover V8s is often an installation problem. I have seen numerous LPG systems where the PCV is still connected to the original port of the plenum. This means that any crank case flame that bypasses the flame trap is discharged into the LPG rich fuel/air mix in the plenum, blowing apart the air induction system. The PCV hose needs to re-positioned to a point before the LPG mixer ring. I have never had a backfire on my LPG setup.

The thing that will most frustrate you is the loss of cargo space, a big issue in a D1. I would be looking towards the twin tanks where the original fuel tank is situated and one of the small petrol tanks in the RHS mudguard. Hopefully also a pair of petrol sill tanks would also help. Fuel endurance on LPG is always less than on petrol. While lots of places have LPG, it is still a problem in remote locations.

Regarding the cost, I was able to do anything I wanted at the height of the fuel price crisis, including trips to melbourne etc because I could always afford LPG. I would have had to seriously consider long trips on petrol.

Fitting a Toyota diesel, you are not going to get change from about $8,000.00

How so?

Even if they put the full 38c/lt tax on LPG it is still going to be a lot less than the price of petrol or diesel because of the low market penetration of LPG. Just look at the cost of LPG at your local servo, add 38c and compare it to the price of petrol or diesel. During the fuel price crisis, the price of LPG was hardly any different to what it is now, except that instead of being half the price of petrol it was sometimes a third of the petrol/diesel price.

Peronally, the only reason I put the Rangie on gas, was because my Bro-in-law is a gas fitter, and I had a 2nd hand gas system ready to fit.

Admittedly it does run alot smoother on LPG, and is easier to start. Although LPG is alot cheaper than ULP per litre at the pump, it works out about the same at the end of the day as the LPG is not as economical, and lacks the power of ULP. (unless you make it a dedicated setup)

Granted, the combination of 3 petrol tanks, plus 1 or 2 LPG tanks gives you great range, but no storage space.

Refused to put a system in the Falcon, as 1 full tank of ULP gets us from Adelaide to Melbourne, and a good way back again. Why lose the luggage space?

Factory fit on new hiace,$4500,Landi renzo gas injection.
They are a bit noisy,but very efficient.Fully loaded,around 430k around town,470k on a run,tank 62l.

If the systm is trouble free,it will pay for itself quickly.
If it plays up ,probably expensive to repair.

And toyota don't have a diesel worthy of fitting to a disco.
The only diesels you'd fit (and want to fit) are a landrover 200/300, an Isuzu 2.8 turbo or the Isuzu 3.9 turbo.

Unless the Labor govt. has changed it, the maximum excise that is to be applied is 12.5 cents per litre - starting at 2.5 cents/litre per annum until it reaches 12.5 cents/litre over 5 years.

LPG is currently excise free but it will become subject to excise in the future. No excise will be applied to LPG until 1 July 2011. The full rate of excise to apply to Liquefied Petroleum Gas (LPG) used in vehicles will be 12.5 cents per litre. This rate will apply from 1 July 2015. The planned excise rates for LPG are as follows:
1 July 2011 2.5 cpl
1 July 2012 5.0 cpl
1 July 2013 7.5 cpl
1 July 2014 10.0 cpl
1 July 2015 12.5 cpl

Our Disco came to us with LPG fitted and it has been superb 99% of the time. There have been a couple of times where I have had to carry jerry cans to supplement the now limited 40L ULP capacity, but a full tank of 76L LPG and a total of 60L ULP gives us a safe highway range of 650km. It is far less when off road, but we're not doing any real outback driving at the moment. Nor are we likely to in the next 3 years.

I have no susbstantial loss of power with LPG. It runs very smoothly, but the best bit is that the current average running cost around town is less than $9.50 per 100km. It's way less than half the cost of running on ULP.

The argument that it's not worth installing LPG because of the future indexed excise increases is akin to putting dog***** on your icecream so the other children don't eat it.

Thanks every one I have been reading all the responses, I am thinking it would be cheaper to buy a Td5 in the long run. This is mostly due to government buggering something good for us mere workers.

Makes me wonder if all the people that got the Solar rebate will end up paying a solar tax similar to the rain water as it will end up that the government probably owns the sun rays but obviously NOT liable for the damage the sun rays cause??
Just the rambles of a man who has 1 year old up all night long

A diesel conversion will take a long time to pay back - if ever.

LPG costs approx 1/3rd the price of diesel but you use twice as much fuel as a diesel (on road). Ergo, in most situations, the running cost of LPG is effectively 2/3rd that of diesel.

Off road, the diesel is far more economical. Diesel comes into its own on long trips (refuelling LPG is an issue in the bush), the range afforded by diesel, and when working hard.
