Hello all,
I am in need of some advice.
Due to an expansion in my family brood (and the fact I could not bring myself to buy a people carrier) I have recently bought my first 4x4, a 1999 RV6 Prado.
As a result of the recent ongoing news concerning petrol price increases, I am looking for any advice (pros/cons etc) from anyone who has expierence of installing dual fuel LPG systems on these vehicles.
Note: I will mostly be using the Prado as a child transporter, (and will hopefully squeeze in a little 4x4 fun at the weekends/holidays etc), so any advice any of you could provide concerning LPG conversions would be most appreciated by a complete jeep/4x4 novice.
Thanks in advance

Generally , V6 Prado's dont like Gas. Nothing specific to Prado's as neither Do Pajero V6 , or Hilux/4Runner V6. Its seems its a V6 problem.
V6's , any of them , can often have a problem with blowing head gaskets due to a build up of heat. Gas , being hotter , can make that worse.
Personally , I wouldn't go near a V6 on gas. Straight Sixes seem to work ok.
NOW , that said . . . there is PLENTY of converted V6s out there , so , they MUST work to a certain degree.
I spoke to a mechanic a while back (when I was looking at buying a Prado) , and he personally had to fix the heads on several Pajeros (both 3.0 & 3.5l), several Prado's & Hilux/4 Runners. He said it was a common problem.
My opinion is , if its a
well known weak spot , do you want to take the chance ?
I didn't , BUT , this isn't my cash.

Interesting you say that about problems with gas a v6 configurations, my v6 commodore on factory gas has had to have the heads done at 52,000km not due to head gasket but due to valve guide wear. Done under warranty. Now 6000km later it has used over a litre of oil (didnt use any before) and about 1.5 litres water and the radiator has a oily white substance in it - to me all spells leaking head gasket!! Holden now think it will have to have the heads off again! Another week with no car. My previous v6 on petrol did 240,000km with no probs
This is my first gas vehicle and I have had ongoing issues with it, I would be reluctant to go with it again hence the reason we recently bought a diesel cruiser rather than a gas petrol even though the gas petrol option would have been cheaper per km

There is quite a few Prados with LPG fitted.
Expect to pay around $2500 for the conversion and a Flashlube kit is a must...
Fuel usage on LPG will be from 18l per 100km to 25l per 100km...
Just do you some to see if you are doing enough km to recover the costs...
If not, I would buy a small cheap car (up to $3000) for every day running around...
