Re: LPG autogas


Thanks Les,

As you have a T31 I wonder if there is a difference in pistons and valves compared to the T30 models which might play a part.

Re: LPG autogas


Hi all,

Was just curious to hear what the current progress for this topic is?

I wrote a nice reply tonight and switching between tabs has made it refresh to blank ... :-(

There is 2 or diff types of delivering/using LPG as a second fuel type? Like direct wet injection or something?
- any better delivery systems to tank other than under rear bumper?
- safe to use? Obviously cuz it's road legal but seriously potential for accident?

So in summary, I looked up that company and found details stating they do Xtrails fitouts but all 3 successive links went no-where.
- Anyone know whether they (Aust LPG wholesalers I think) still fitout LPG tanks?
- Also was this an Adelaide based company

In terms of cost
- original estimate like 2-3yrs ago posted on here was $4-4.5k with a $2k rebate at the time to be reduced to $1k
 * costs now?
 * rebate state or fed thing or nonexistent anymore?
- fuel economy of LPG still good?
 * current cost of LPG $/L
 * availability, I.e. Rural servos cuz I live far NW Qld

Just wanting to see whether I could utilise my unused tyre well better while delivering greater distance to fill benefits. I see from previous postings this system can pay itself off when gas was half the price of fuel for the same economy and considering I drove 20,000 in 6 months could pay this off sooner than most.

Cheers for your updated thoughts,
Ben

Re: LPG autogas


Our x-trail is now in the mechanics with 2 burned valves from the LPG after only about 70000klms.We fitted the liquid system thinking it would be a lot better but sadly no, the bill is $2500 so far but a least it will have the hardened valves it.

Re: LPG autogas


Hi Steve, sorry to hear about your problems.
Could you give us a little information on how much of the time you ran it on LPG compared to petrol and what length of time was the intervals between petrol uses ?
When enquiring on the liquid injection system as they just came out, I was told by the installation company that they recommended running petrol for a percentage of time to lubricate the valves and stop them burning. There is also a product they use in the UK called "Flash Lube" for this. Have you used any ?

Re: LPG autogas


Hi Kev.it started on petrol and ran a few minutes before switching over to gas automatically. We would run about 1/2 a tank of petrol every few months or so so not a lot really, maybe in hindsight possibly could have been a bit more. When we got it installed I don't recall any advise other than the usual about running it on petrol every now and then and nothing about flash lube, which I had the understanding that as it was liquid injection system it did not need flash lube.

Re: LPG autogas


Have you contacted the installer or manufacturer's importer about the problem to get their response ?

Re: LPG autogas


No we haven't and with out going off topic I don't think they would have much interest as it is out of warranty and we had a few problems with them at the start. I think it is just a case of the valves being too soft for lpg, its not just X-trail motors it a lot of Japanese motors. So I suggest to anyone thinking about putting lpg on their x-trails to do a lot research before hand.

Re: LPG autogas


Just a quick update on our car, it turns out the lpg system has had the wrong size jets in it resulting in too much gas going in and thus burning hotter which caused the valves to burn out. It going cost about $600 to put the right ones in so at moment we are running it on petrol which with the cheap price of petrol at the moment the running cost are pretty much the same as it would if we were using gas.

Re: LPG autogas


Surely Steve, THAT is an installation error and ALL costs should be covered by them, INCLUDING replacement of any damaged pistons and not just the valves.
