My husband was recently speaking to a caravanner whos friend has recently fitted an LPG induction system to his turbo diesel Nissan Patrol. Apparently he is getting upwards of 80-90 newton metres of torque extra and uses 2 litres of diesel less for each 100 klms travelled. We don't know how technical he is but he talks about the fact that diesel combustion only operates at 75% efficiency and when a 20% LPG is injected into the combustion chamber a burn of 100% is achieved. The stated cost of this conversion is $3800-$3900. However with a Govt subsidy of $3000 makes this option very attractive and "apparently" this chap recouped his $800 in just over 6 months. Our concern is that we have a near new 4.2 lt auto turbo diesel landcruiser (under warranty). Unfortunately we know nothing of the technical side and would greatly appreciate hearing from anybody who has either fitted this conversion as to whether it is a sensible option having regard to the ever increasing fuel costs.

A real dumb question.
How much does the LPG cost that is used to save 2 litres of diesel? This is not a sarcastic or smartybum question just one from someone who is interested.

Finally read the post above and visited their site. Looks interesting if it doesn't shorten the life of the motor for whatever reasons.

Yes the initial cost is reasonably high, but I will recoup all of my costs in about 12 months, and that is just with normal day to day driving. With diesel currently at about $170 / litre my combined diesel / LPG cost / litre is around $1.37 thereby saving me approximately 30+ cents per litre overall. Thats $30 - $40 / fill at one fill at least every 2 weeks, the savings definitely do add up, not to mention the 20% - 30% power increase and cleaner running.

Thats correct. WA is $3K total rebates from Federal / State whereas all the other states on get the Federal rebate of $2K.

At that rate, why wouldn't you convert, probably even better for the engine because it would burn cleaner and leave fewer deposits in the oil...silverback

I think the Federal subsidy of $2000 will change in next weeks budget.
Some have rumoured it will be abolished but I think its more unlikely that the subsudy will be reduced -possibly halved.
All will be revealed on May 13.

What I find interesting is that to fit the LPG, on some vehicles the main fuel tank is removed, which I find absurd!

And also that an aquaintence of mine who is a mechanic by trade and is currently working for an LPG fitter in Perth tells me they won't touch diesel/gas because of a "catastrophic malfunction" experienced by a chap who is currently seeking legal advice after fitting LPG to his reasonably new turbo diesel Rodeo.
