This is not a negative comment but I need to ask

What are the advantages of a dieselgas conversion?
How long will it take to recover the cost of the installation?
Will the engine run hotter?
What will the long term effects be on engine wear?

If you have satisfied yourself that it would advantageous to go with the dieslgas, then go for it

Cheers

I saw an install on a Discovery turbo diesel by one of the largest LPG installers here in VIC and it was a very unimpressive job.
A simple egg ring mixer installed upstream of the turbo into the turbo air intake so it restricts airflow for a start. A simple variable valve assembly to regulate gas flow.
Then we have the added problem of the LPG being introduced upstream of the turbo, it is then compressed and is sent on its way to the engine through the intercooler and all its associated plumbing to the inlet manifold. We now have an explosive mixture under pressure in a whole lot of plumbing, admittedly, a diesel is far less likely to suffer a backfire than a petrol engine but this isn't "world's best practice" at all. Imagine a ZD30 with a leaking intercooler (a few have been reported) leaking LPG around the engine bay and an ignition point, not a pretty thought.
In the early days of petrol turbo's when carby's were mounted upsteam and some bright sparks used intercoolers as well the petrol would condense and collect in the intercooler and if there was a backfire which was pretty common in those days it would blow the front of the car off.
People quickly learned don't put an explosive mixture under pressure through the intercoolers.

Where do u mount the tank so you dont lose normal fuel capacity...

what happens when you run out of LPG since you wont have matching capacity in LPG to Diesel tanks, so when you think about it, you keep driving in the end on pure diesel anyway so in reality there is no gain long term. Just a feel good while the tank is full.

I actually followed a current model Landrover 110 to work last Thursday morning and it was taking off just a little bit too fast to be a normal Landy. My work vehicle (2006 Navara 3 l turbo diesel) couldn't keep up with it. I eventually caught up with it when it stopped and confirmed my suspicion that it was diesel/gas. I got a chance to test drive it last Friday. Drives like a petrol vehicle, runs very quiet, has good take off from stop. I think the only negative is to watch out for speeding fines. Costs about $3500 - and with Federal Government rebate of $2000 plus WA government rebate of $1000 only leaves $500 left to pay.

Hi Twinkles

I have just had LPG installed to my GUII Patrol 3 litre DT. I have not completed 1,000 kms yet but have been on a short 4wd trip with a few short low range sections and some steep highway hills.

Noticed an overall improvement in performance and engine smoothness.

So far the economy seems great but it is far to early to start quoting numbers.

I have a 30 litre LPG tank mounted underneath my Patrol. LPG is injected into the air intake at about 30 litres of LPG per 100 litres of diesel. The savings are not as significant as a petrol LPG installation, but with the Governments rebate of $2,000, I calculate the pay back will be take less than 40,000 kms.

I have researched LPG diesel dual fuel on the internet. It has been used in the UK and Europe for some time. It produces savings in the use of fossil fuels, lower exhaust emissions of noxious and greenhouse depletion gases and lower exhaust temperature.

Do a search on Google Australia using "dieselongas" and "dieselgas" for more information.

I could not find any negative reports from qualified and experienced sources.

Hope this helps

Regards
Phil

I'm still waiting for the answer to the question 'what happens when the diesel runs out'? Can you still keep driving with diesel only performance, or are you stuffed? What happens when you do a Simpson trip, can carry 140L of diesel (some in Jerrys) but only have a 30L Gas tank, or do the CSR, you can pick up diesel but can't pick up gas??

Anyone got any comments on using it on a TD Jackaroo?
