Lpg Liquid Injection - Part 1

[T2000]

Mine pretty much equates to 25% more gas, although others on this forum have stated better figures, some around 5% difference I have had a tune and it's just the same.

Just logged ~250km, 50Lt LPG, ~4.5 hrs driving, Avg Speed 48kph.
Some highway, some traffic (stop go) & some yeehaa moments.
LiLPG, Rotrex SuperCharger & Baby Cam.

Pretty happy with those numbers considering that there is still room for improving the current tune.

You should not be using 25% more - personally I would get that checked.

I paid $4725 for mine fitted with a 110L torpedo tank, minus $1750 rebate left me $2975 out of pocket. Doing 45000km a year I broke even in around 6 months.

I find it ridiculous that a gas conversion costs $5000.

Would love to see everyones usage and savings.

If you are using 25% more gas than petrol, then thats a savings of only $25 a tank. Based on a tank a week, it will take you 3-4 years to break even!

i've got an excel spreadsheet that i made up and fill it in when i can remember, i'll post the screen shots up when i'm back from work.
i'm definately saving money with the LPG system with a baby cam in my ve GTS, and i use onpar or not a tad more lpg then petrol. as t2000 said there must be something wrong with your setup

An LiLPG will get the same economy from LPG as petrol.

If your spending $100 a week on fuel, LPG would be saving you around $60-70 per week. A $3500 conversion cost (out of pocket) will be recouped in just over 1 year (59 weeks with a saving of $60 per week).

If you keep the car for 5 years, you'll have saved around $12,000 in running costs. So considering the higher power output and fuel savings, i would consider that pretty good value for money.

Lucky I do approximately 40k per year so it only took 16 months from my calculations, that was back in oct 08 so definate savings now.

Who was your installer and have you had it tuned to the gas or dual tune?

So how close is your displayed usage compared to your actual?

Matt,

I got the car done in WA by the car doctor in port kennedy, very neat install done.
i drove around for a year on a single tune wainting for my tuner to do dual tables but unfortunately he used HP tuners, So i employed the services of OZTrack a few months ago, he reflashed my car with efi live and enabled the ethanol tables and i hardwired a a 12v pin into the ecu to let it know it's running on lpg at the time and i have noticed a difference in economy and performance. when i'm back from work ( im fifo ) i will put up the excel sheet showing you the differences.

to be honest i haven't looked at the displayed usage but will keep an eye on it now, as i usually work out what i've put in the tank.

Thanks ace
Looking forward to the results.

I find it ridiculous that 98 RON cost $1.60 a litre

I find it ridiculous that Holden chose to copy your ute when they designed the new VE II Thunder!

Seriously though if people dont see the value in investing in a quality conversion then that is their choice... then they can "contribute" to the forums bitching and moaning that LPG is not as good as petrol.

Wise investments are rarely insignificant nor do they realise short term gains.

Yes it is expensive, but it is quality and will provide significant return on your investment long term. Name any other investment where you can return around 1% on your capital each week? Or 50% pa? (assuming you are saving $40 per week on a $4000 spend)

A tuned LiLPG setup will cost only a little more than a full exhaust, OTR and tune (after cash back). And it will produce a bigger gain in RWKW and save you at least a case of beer each and every week that you own it.

AND not pay tax on that return. If your getting a 50% return on any other investment, you'll be paying at least 30% tax on that.

i just got my ute put on jtg and im really happy with it so far, but has anyone else noticed that the lpg tank level seems to drop over night?
im thinking i have a leak cause if i get home the night before and the tank level is low (but not empty), the next morning i cant run on gas till i fill up cause the jtg just beeps saying its empty
could different ambient temperature cause this to happen?
i havent noticed any gas smell around the car

cheers

Temperature definitely effects the effective volume of LPG in the tank. Hot days you will get less in at the pump. Pretty sure you should not be having issues the next morning caused by temperature. If you do have a leak it would have to be at the tank though... once the engine stops running the lock-offs isolate the tank.
Definitely get it checked... my tank has never lost volume overnight or suffered the conditions that you describe - so I am guessing you may have a slight leak.

GOOD LUCK!

Cheers, Chris

Those 4 lights on the LPG guages are not exactly known for their great accuracy. I ignor mine and just go by km travelled or when I just start to feel the tank getting low by the pumps getting a tiny bit noisy. Easy to do after a few fill up and you will get the hang of it. I have read there is a fix for the guage accurary issue but noting I can do about up here so have not persured it

post!!! i want to see calculations.



does servicing the gas conversion cost more or an ordinary service will do?
