Hi everyone i have a 1990 vn commodore and it SHIT on fuel. I dont know why i have replaced everything! It only went shit on fuel after i put another engine in it and converted it to manual. I was just wondering roughly how much they charge to do it. I have the gas conversion kit. Its a shit car worth like $500. Im sick of putting fuel in it all the time. I spend more time at the petrol station than i do driving it. I cant afford it anymore. Im in australia aswell if that makes any difference. Cheers.

This was all I could find. These vehicles are not popular in the states.
I wish I could be of help, I will say I love my 2009 Holden packaged in Pontiac plastic, nothing sweeter than teaching a backward ball cap wearing Subaru WRX driver a physics lesson at a stoplight with an unassuming debaged v8 4 door.
I assume you are refering to CNG(compressed natural gas). As collegeman stated this system ain’t popular in the states however, I know enough about it to give some insight. First, you will need a CNG compatible tank as your gas tank will not suffice. The pressures are much higher for CNG. Next you will need all new fuel lines capable of higher PSI and the engine will need to be slightly altered to run on a higher compression because CNG will need it. In all honesty unless you are prepard to do the work yourself, it may not be justifiable. In the USA, the gov will give you a small subsidy towards the conversion.

Above is a link if you are truly interested in this.On a youtube video I heard a CNG advocate saying you could recoup your $3000 investment in 2 years of normal driving. On the other hand, the USA has a surplus of natural gas. I have no idea what the natural gas situation (and natural gas price) is in your country.

Gasoline has more BTUs from my understanding.
Sorry, my understanding has the same gap as yours. I was just repeating something I heard on the internet and you know they can’t post any lies.

Anyways maybe someone more knowledgeable on the source will chime in here.
I was a certified installer of Natural Gas and Propane systems here in Ontario Canada for 12 years. What you guys are saying is true to a point. It is very cheap to run but the maintenance is a killer. The tank(S) are heavy and in a car the tank would consume most of the trunk space. Filling stations are sparse also.
I could go on and on about the pros and cons but if you’re interested and want my story let me know.
From what I understand, Propane (LPG) is somewhat in use in Australia and in my opinion is a better choice than Natural gas. Because Natural Gas is a vapor (up to 3000psi) and propane is a liquid you can drive further on a fill up
For our poster I suggest that maybe you could find an installer with some used equipment that might save you some money. If you find someone knowledgeable your car should run like a kangaroo and much cheaper too depending on the cost of propane there.

Bill,
Actually and Seriously, I would love to see a write up about this…. Please do it if you can… I have not dealt with LPG or CNG…. Ironically, A few years ago I “choke” was considering buying a CNG Honda due to high petroleum gas prices and being a “good global citizen”… 🙂 LOL….

-Karl[/quote] I agree, at some point I may want to convert half my dual tank fuel system into a CNG setup so I can have one tank for Gasoline, and one for CNG and can toggle between the two with the switch. It would be nice to have some information on the subject here!
Yes, NGV is fewer BTUs than gasoline and propane. On the antiquated systems that I used to install (fork lift carburation) the fuel goes into the intake manifold as a vapor and that vapor (vapour in Canada) displaces some of the air. The combination of lower BTUs and intake air displacement caused a decrease in power.

I would love to do a write up on the subject when I get some time but some things have changed since I was involved. Most of the fuels are injected now.
My story takes a lot of twists and turns. It was fun being an installer, welder, engineer, electronics guru, a chemist and a methane expert as well as knowledge of physics. I never had a grey hair on my head before working at that job however.
