GU patrol on LPG

Craft,
I have had 2 GQ's on gas in the past and was quite happy with them overall but the price to convert my 4500 GU was too high to make it a worthwhile investment when I originally purchased it in '97. I was told when updating to my current vehicle that Nissan did not recommend a gas conversion on the 4800.

LPG is for cooking chops and sausages!
Wear out your motor quicker cause more problems than its worth.

I know a few guys that have recently changed over to LPG on their GU's.

Both converts are extremely happy , that another mate , and myself , are consdiering doing the same to ours.

I SHOULD have bought a dual fuel to start with . .. doppy bugger.

During my research , the 4.5 Patrols are almost built to Run on LPG. Nothing needs to be done to them.

I have NEVER heard of anyone having major issues with LPG on the GU's.

The problems I have heard about are , reduced range. Not surprising , but can be fixed to a large degree with a larger Petrol Tank (change the sub to a 85l).

Reduced ground clearance. Small lift , 50mm often fixes that.

Reduced power , One guy said he didn't notice ANY difference in power between LPG and Petrol, the other guy has a Unichip fitted anyway.

Fuel economy on LPG is approx 1/3 more then Petrol , so you need to do all your figures to see if its worthwhile for your use.

I believe you need to do over 20,000 k's per year , to break even in approx 2 years.

The reason cabs do so well is they are driven constantly almost 24 hours a day and are always up to temperature.

As a gas fitter GU patrols are excellent on lpg Prop one of the best vehicles to convert just fit proper LPG ignition leads to stop back firing and it will run like a dream price on conversion should be around 2200-2400 using impco system .
Are great to install as you use orig guage and sub tank switch as lpg/petrol swith there are no guages or switches added it looks great..

Thanks very much for all the responses. It seems it is ok to do and as I test drove a GU today that could be a go it looks like I will be doing this sooner rather than later.

gqpat,

Are there any long term issues with the gas? and how often should you run petrol through it?

99.9% guarrantee after 200,000 klms on gas you WILL have burned/ressessed valves.
cabs are bought for their respective cheapness!
Not longevity or performance!
An uncle(in Greece) says they buy merc diesels as cabs there because they will go for 1milllion klms (his has 700,000klms), and also because they are cheaper
After 400-500k klms the cab will be retired.
That's about the time the valves will have burned through!
Poor sod that has to fix that, and put up with the vinyl floor!
Cabs aren't without their fair share of problems, mainly overheating(due no doubt to the gas conversion!)
If the valve operation in the Nissan is hydraulic, not by shim or locknut, you may never notice it until it's time to do the hydraulic adjusters too. $$$
I dunno nuthin' about Patrols, except my mechanic has an MQ on gas, and it burned its valves, and my 98 Rodeo is burning them out too.
I've done 240k Klms since the conversion (LPGas1, standard Holden type), it needs the (shim) valves to be adjusted everyr 5-10k Klms, and if not it drives like a bucket of bleep .
I can assure you that if diesel was as cheap as LPgas, all cabs would be diesels!

I have had a gu patrol 4500 on ga for almost 2 years now.
It was already converted when i purchased it.
So far have done close to 40000k without any dramas.
range is an issue due to supply of gas but anywhere on major roads you wont have any problems getting gas.
so far with the small amount of off road stuff I have done clearance hasnt been a problem and paying 40 cents a litre compared to 1.26 a litre makes a difference
