I have done 62000 ks since installing JTG Liquid injection and I could not be happier. The saving just keep climbing, look after the cents and the dollars will look after themselves. The oil stays clean and does not discolour, between services done at every 15000ks . over 7632ks fuel useage 12.4lts per 100

I've just clicked over 115,000 klm's since the JTG conversion and can say a bad word about it.

Allot of people are researching LPG so I would like to add to this post.

I have just installed an Orbital Liquid LPG system to my fiancée's 2009 VE SS. Why? Now we have a family car that looks good, sounds good, has loads of power, is fun to drive and now is fuel efficient. With fuel prices soaring to 160+ a litre (and that's just for E10) it made sense to me.

I chose orbital as the car will remain pretty much stock (except as I have done now - got rid of the rear mufflers). I also did some research and it appeared to be the system with the least amount of problems and best customer service. I also chose the doughnut tank in place of the spare wheel. I got hold of a space saver for the longer trips away, but am going to get a compressor and can of goo for the short trips.

I will obviously need more time to evaluate the system, but there is no real difference power wise between gas and fuel, if anything the LPG is smoother and has more low down torque.

This is not the first car I have had converted to LPG. I have now had mixer (venturi) style, gas injection and now the LLi. The LLi is more superior to the other 2, and is worthwhile now it is only a couple of hundred more that gas injection. If it were say $1000 difference, I would have gone with gas injection.

Venturi/mixer style LPG on EFI cars is rubbish. You loose power and expose your vehicle to potential long term engine damage.

My suggestion to people is if converting your car to LPG, make sure you chose an installer who specialises in LPG, I test drove a 5.7L LPG statesman the other day with mixer style LPG that was a disgrace to an otherwise beautiful car. Avoid people who say your car is rubbish or they won't touch it - sign of an incompetent LPG installer. Think about where you want your tank - I chose mine as I can still use my boot and on long trips can pack stuff on top of the space saver. I can also still access the boot from the rear seat.

Now the system I have is an orbital series 500. I have not had any issues filling the car and it doesn't revert to fuel at high RPM or load. The system cost $4600 installed with a doughnut tank. This system does not require special LPG oil or different spark plugs like other systems can. And the rebate $1000 is still available.

Nice. What's the LLi use now litres/100? Where did you get it done?

Hi, I got my LLi conversion done by The Gas Man at Seven Hills. The gas consumption is pretty close to fuel. I'm getting around 425km out of the 56 usable litres (I have only put about 4 tanks in it so far all about the same) so around 13l/100. On Fuel I was getting around 550 out of a tank, using about 65 Litres so around 11l/100 ($99 to fil at 1.50/l) - this is combined city/highway driving.

I am happy with that, it was never what I considered really bad on fuel. It appears to be better on fuel/gas than the old factory gas VY we had.

Mine is not the AFM model either so I would imagine it would be a bit better. I can't make comment on other vehicles, but our particular SS was no better on PULP than it was E10 so she got fed E10.

One note of caution, the Gas Man said to run as much E10 out of it as I can since the conversion has been done and feed it some regular stuff as it tends to separate after a period of time.

The system I got comes with a 3 year warranty. The LLi delivers cooler LPG therefore the valves aren't exposes to the heat of the older systems so valve recession shouldn't be an issue.

I have done just over 80k on Liquid Injection and I am very pleased with the set up I still have the power if not more and at half of the cost, and sometimes even cheaper, with petrol at 1.65 today and gas at 79.5 the money to be saved quite noticable. It was not long ago about 8 weeks gas was 59.9. After recouping the cost of the installation, every time that you fill her up you know that you are saving , my system cost about 5700 minus the 1500 rebate and then I think that I save about 2000 per 20000k if my memory is correct.
