I own a 2000 TJ 3.5L Sedan. Since petrol prices never seemed to go lower, I am just wondering what are your comments in converting the car to take LPG? What's LPG fuel consumption like? Also, how much for such a conversion and whether the conversion is reversible? Thanks

umm, its bout two n a half grand ( i think) and it is reversable, i have also heard mixed storys bout the performance, but the majority say you lose power wif lpg

What about fuel economy? Do you still get around 7.2km/L of city driving like Unleaded Petrol?

If you do a straight conversion without rebuilding the engine to suit gas you will lose a bit of power and the people I know with LPG cars reckon you end up paying around 2/3 of what you do now on unleaded. The fuel is around 1/2 price but you end up using more, this depends on the engine but anywhere up to 50% more fuel would be in the ballpark. So what used to be a 600k tank would be a 400k tank, but instead of costing 70 it would cost around 35. Also when you get the gas done(somewhere around the 2k mark) you get a 500$ rebate, so it's going to cost at least 1500, you have to own your car a while to save 1500 in fuel :P
Hope this helps

There was a story on the t.v a couple of nights ago, they said u do lose a little performance and fuel econamy but ur still paying less per km to run the car, they also said it would take approx 19,000km to repay itself, for me thats only about 6-9 months, but others could be 2-3 years, just depends if u drive alot.

In terms of maintennance cost, how does it compare to Unleaded Petrol? Does it need more frequent services?

Does conversion means dual fuel or will the petrol tank taken out and refit with LPG tank?

If it's dual fuel, where will the new tank sit and where they going to fit the refill point?

I've asked Lidcombe Mitshubishi in Sydney. They told me they don't do such conversion there. Is it an outside conversion job or is there a Mitshubishi branch in Sydney that does it?

Thanks

The conversion is straight forward for a fitter. With modern Computers and Fuel Injected cars there is no power loss noticeable. I get 350 - 400k's out of a LPG tank and pay $20-$25 to fill in SA. As long as you are planning on keeping car for 2 years or 40,000K + you will pay for it no prob. It burns cleaner than Unleaded is more environmentally friendly so your service intervals will not change. Only disadvantage is you lose 1/3 of your boot space. Most good fitters will fit LPG connection in beside your Petrol Filler. The advantages are worth it. I won't pay petrol prices and haven't for 10 years. It uses a bit more than petrol but benefits still outweigh disadvantages. Hope this helps.
I am looking at selling Verada in next couple weeks anyhow and buying new Magna LS and putting Gas on it

Mind showing me some pics how they find room to fit the LPG connection beside the Petrol filler?

Also, how you know you are using fuel from Petrol tank or LPG tank? Is there some sort of user control switch to select which fuel source to use from? What about the gauge on the 2nd tank. Where does it sit?

For those in Sydney, any advice on where to get more info on it?

Thanks

Its a very tight fit beside the petrol filler (sorry no pics).

There should be a switch that they mount on your dash that has the option of either gas or petrol. The gauge is actually on the gas tank inside the boot. I have heard that you can get ones that go in the dash but they are expensive, so you are most probably just going to have to rely on km's travelled.

Whats this about a $500 rebate??

also has anyone heere installed that vaporise thingie? that new invention using all the fuel,, Repco ad says you oculd make a substantial saving also, dont know itf its true or not, that cost $400 all up i think

costs around 2-3k. Performance wise there defently is a drop, and there is also a drop in fuel economy. However per km you will be paying less on fuel. And yes a conversion is reversable.

One thing you have to first consider is how many k's you do per week. Obviously if you do like 700km's per week you are going to recover your investment of 2-3k fairly quickly, but if you just drive around town and so forth and dont do that many k's then its going to be years before you pay off the investment, and during those years the price of LPG may rise (in the last 3 yeras lpg has risen from 25-30cents to 45-50cents and that trend may continue)

I caution to check with Mitsubishi befor going throught witht the LPG conversion as not all TJs are compatible - ie. my AWD is not, although they have the same engines.

I've been struggling to find out why. Mitsubishi won't say except that I'm talking to the customer service centre where they don't despense technical details except repeat the emailed statement from their technical department which consist of the word "NO".

The main problem is valve seat recession. I can't determine if this is a realistic problem or apart of unexplored territory that never undergone testing by the designers for the AWD.

Any experiences and input from others in the know welcome.

i ahve a TH advance with DUal Fuel.. apparently it as a factory option for the TH advances! but yeah. i got a little switch on my dash and my LPG filler is next to my petrol one.

one great thing is.. theyhave some how hooked up my petrol gauge to the LPG too.. so when i switch over to LPG it shows the LPG reading.. and when i switch to petrol, it shows the petrol reading! AWESOME!

MAGNA SEDAN WITH LPG
The Mitsubishi Magna dual fuel (petrol/LPG) sedan reduces the level of carbon dioxide by up to 20%, significantly reducing the 'Greenhouse Effect'.

In conjunction with IMPCO Technologies Pty. Ltd., we have developed the Magna dual fuel (petrol/LPG) sedan, which enables outstanding savings in fuel costs while also reducing air pollution without sacrificing performance.

The Magna Advance 3.5 litre V6 auto sedan is available with a factory endorsed dual fuel LPG system (optional on Executive 3.5 litre V6 auto sedan, fitted with the optional LPG compatible engine). Using LPG reduces the level of carbon dioxide by up to 20%, significantly reducing the 'Greenhouse Effect'.

these are just a couple of reasons why if you do decide to go down the LPG route, get a proper factory LPG setup. I have heard of some VERY dodgy aftermarket LPG setups... :doubt:

Choonga, where is your lpg tank located. In the boot?

lpg has a higher octain rating than optimax if system is set up the right way you will have more power than any normal fuel however this will only work if the fuel system is scraped and if running straight lpg the fuel econ still isnt the same as fuel but is better than if running duel fuel

bet they wont warrent ya motor when it burns ya valves out

also has anyone heere installed that vaporise thingie? that new invention using all the fuel,, Repco ad says you oculd make a substantial saving also, dont know itf its true or not, that cost $400 all up i think

yeah mate.. boot.. nowhere else it could really go

LMAO imagine it being on the parcell shelf or stuck to the roof or something ! ROTFLMAO :bowdown:

Indeed there was a factory option, but not a dealer fitted item. So if you want LPG now, aftermarket is the only way to go.

I've had a couple of conversations elsewhere about the performance levels of LPG. The outcome came out that LPG is superior in performance compared to unleaded fuel however only if the engine was specifically tuned for LPG, ie. permenantly disable the use of standard unleaded fuel. We don't see this everyday because many people opt for dual fuel for the convenience rather then for performance.

my family have owned a car on gas before and we paid bout $1500 and it was shocking. car overheats in summer, it backfires when u put ur foot down and so many problems. my dad bought a 02 Pajero exceed 12months ago and he put that on gas also but this time we took it to Gas Research. we paid $4800 and they did an excellent job. they actuall did sum tests first to see if the engine can handle gas. as sum ppl say car does lose power when on gas but it depands on how the car is tuned. since my dad drives on gas 85% of the time they have tuned it to get max power from gas. i can actually notice the differance when i flick it from gas to petrol and i think its more responsive on gas. from what i think gas is not that bad, it jus depands where u take it. gas research has its own racing team. they have a twin turbo ED ford fairmont on straight gas and they reckon it goes better the petrol cars so from what i think they know what they are doin. shop around and do sum research and c wats best. and as for maintenace we jus had our first service 3 days ago and thats 9 months after gettin gas.

hope that helped.

if LPG actually makes more power when tuned properly then petrol, then now come the gas falcons which are 100% gas (ie have no petrol tank) only produce 150kw instead of the petrol engines 182kw?

Hey all,
Got my TH on gas and while there is only a small difference in power the car does run a bit smoother on petrol though. Last dyno run was 121.7kw ATW in an auto 3.5 on LPG. The tank goes in the boot behind the rear seat. The filler sits next to the petrol one behind the petrol flap. it's a tight squeeze but looks neat. I get about 350 - 400 to a tank. costs me about $20 to fill empty to full. (62 useable litres). Best of all is mine was factory fitted. The heads are built for LPG so no valve save bottle needed. The draw back i'm dealing with at the moment is that apparently you cant force induct an lpg vehicle cause the gas pressure isn't enough to keep up with the rate of air flowing in. Having said that i do know of older cars with carbies that are super charged and are on gas. :confused:

I'm getting a gas conversion eventually for the daily magna, theres a place in Adelaide that fits them for mitsu so i'd say they'd be the place to go for me.... :D

hey mate. how can i tell if my heads are different from the normal ones? anything i can look at?

and damn.. how much is gas over where u are? its currently at nearly 50c here in melb.

well from what i think getting ur car tuned from factory and getting ur car tuned sumwhere else makes alot of differance.ne car petrol or gas if u take it to a performance place to get it tuned it will make a lot of differance. so if a factoryfalcon with gas produces 150kw maybe taking it to a performmce place might tune it better and therefor get more kw out of it. but i could be wrong... from wat i know my dads pajero runs better on gas then petrol.

correct you will be able to get more power by fitting a unichip or whatever and having it tuned up, however i have never heard of someone gaining 32kw with just an ECU tune...

I have a tj magna on LPG factory app.Me and the wife do 600km per week coosts us 30-35$lpg..................... on petrol well youse know eh?

My tj was lpg factory approved adelade imnco or something.Great car runs like a dream 200,000 still as quiet as a mouse.I have yet to see a TJ on duel for sale.Saves us a fair quid a week and with no loss of power"still freaks me out when the wheels spin :cry: "I cannot recommend it enough boys and girls. Good luck :D

My TF is on gas, I notice a performance hit, but seen I don't race it, filling her up for $25 makes it all worth it.

Direct liquid injection gas makes more power, but costs alot to setup.. more than your current LPG $2500 conversion jobs which are gaseous injection.

If you want a good read on this technology go here. (http://www.gmi.edu/%7Elpgvan/SAE-LPG.html)

FUNNY HOW THEY ARE USING CAMERYS NOW NOT FORDS AND THEY WANT ECONOMY NOT PERFORMANCE YOU DONT NEED A COMPUTER FOR LPG THE ONLY REASON THEY USE ONE IS FOR POLUTION PURPOSES .


You also don't need fuel injection for petrol, you can always go back to a carby - no thanks!

Don't try compare this, i am aware of what a bmw has and the ford, (though they don't compare in the Bullsh1t stakes to the audi's i work on) anyway what i was saying is that you were complaining about how difficult and technical fords LPG system is, which by the way is fitted to a new car, and in turn all new cars are full of modern technology, so do you really think that ford would bring out a primitive lpg system alongside all the tecnology in the new car market.
M8 I WORK ON ANY TYPE OF CAR INCLUDING AUDI SAAB ANY EUROPEAN USA AUSSI IF IT DRIVES IN ILL FIX IT. IM NOT COMPLAINING ABOUT THE SYSTEM. HEY THE MORE CRAP THEY FIT THE MORE WORK I GET. ALL IM SAYING IS THEY ARE MAKING CARS HARDER THAN THEY NEED TO BE.
