Hi - this issue has received a bit of publicity lately and the apparent benefits are appealing:
. more efficient combustion resulting in 20-25% inc in power, reduced fuel concumption, quieter running and cleaner outputs (advantage for environment and oil quality). Plus LPG is obviously cheaper than diesel.

I guess the disadvantage is the cost - does anyone know anything about conversion (presumably as expensive as a normal petrol vehicle conversion as an LPG cylinder would be required plus other mods under the bonnet - $2-3K?). Another possible disadvantage may be engine longevity although this may also be enhanced by a smoother/cleaner running motor?

I remember a few years ago when I used to do Diesel power house work that some of the engines ran of a mixture of 10% diesel and 90% LNG not LPG. As far as I can remember the LNG entred the engine via the intake manifold.

Supposed to be good, with power increases and less emissions. Only down side is payback and extra heat could affect the injectors, aswell as LPG becoming taxable in the next few years as in the last budget.
Simply, you put a gas carbi in the inlet and turn down the full fuel diesel adjustment, replacing it with lpg. So the lpg comes in at 1/3 throttle and the diesel goes to about half full fuel (these are rough figures) meaning it starts on diesel, idles on diesel, runs 60/40 at half throttle and 50/50 at full throttle.

I believe that Brisbane city council run some of their buses on LNG if that is of any help. Regards Salty

Hi Pathfinder,
Went to a meet at Landcruiser Park Mountian a few months ago and spoke to dealer in these conversations. Yes, every thing you say is what he told me and the cost for a GU Patrol 3lt TD was $3000. My biggest problem with this concept is where do you put the bl--dy big round cyclinder and still have room for the kids,and gear.
