lpg injection

[JIMI Lurker Find all posts View Profile Close JIMI]

I have a 2005 t/d auto which I am seriously considering putting Diesel lpg injection on it. Has anyone had much to do with it or know anyone with it. I have been told it costs around $3800 which you get $3000 back from the govt. They fit only a 25l tank to it and you still keep both of the diesel tanks. I look forward to hearing from anyone.

Hi mate - by no means an expert, but I believe there are major differences between systems out there, in terms of (claimed) power/torque and efficiency increases versus price.

I am fairly sure the govt rebate is only $2,000 (or at least it was when I was looking). I got a ballpark quote from Team Green Autogas in Brisbane for a 105 series 'Cruiser i was looking at before the Prado and it was $4,800 so I think maybe have a look at the details fo the system they're fitting before you commit .....

On a side note, when I was doing my research I was told the ratio of lpg to diesel was around 1:3 so they were looking to put an lpg tank in of approx 1/3 of your normal tank. On a 120, this is gonna be a 60 litre tank, not 25. 25 litre might be fine for say a td5 disco with only an 80 main tank or whatever they have, but it would suck if you paid the money to get this put in, and then to fill up on lpg three times for every tank of diesel you put in (especially on an outback trip).

To be honest, when I sat down to work it out on the Prado, I figured it would be money better spent on at least a top notch exhaust (Beauy pr Taipan) and for under $1,400 (from memory) and if you had the extra dough maybe a chip - just imho. The tanks on a Prado arew about as big as a Brontosauras' ball sack, so go for a bit more power and economy instead .....

We get $3000 rebate in WA - $2000 from the federal govt and $1000 from state govt. I know there is alot of different brands of lpg injection out there and they all sound similar which is why I wouldn't rush into anything till I heard some feedback.
I am interested in an exhaust but the wife who drives the car doesn't want anything too loud. Does anyone have any comments on how good the exhaust really does make the car and what noise increase they generate?

Jimi, didn't realise the extra grand you lucky sandgropers

If it would only cost $800 I'd seriously think about it, but still I've been told the lpg:diesel is a 3 to 1 ratio so you'd need a 60 litre gas tank - 25 litre means you would need to fill up 3 times to every tank of fuel.

I haven't got an exhaust yet, but the advice I've got from this forum is you can have a good system with negligible increase in noise - try a search of the forum for people with more experience than I ...

I spoke to a guy from ecoshot today and I expressed my concern about the tank size and he said it probably wouldn't do the whole 180L because they usually inject at about 20 - 25% for best performance. He said that it is probably the only tank size that would fit - his Navara is done and he thinks it is really powerful probably drives more like a petrol. But when the gas runs out you are just back to normal diesel operation apparently. Also with diesel prices the way they are I am usually only putting 100L in at a time unless going on a long run.

I got the same story when i looked into it a while back. runs the mix while it can then back to just diesel when the gas runs out. they also talked about removing the second tank to fit the LPG tank but i wasn't a fan of that idea and i didn't want it fitted in the cargo area so gave up on it.

I have the Diesel Gas kit on my 120 Prado (Last of the 2006 models - older style diesel engine).

I havn't done a dyno test but I estimate around 15 - 20% power increase. The performance is immediately noticable. They moved the exhaust to create a space for a 30 litre tank which sits underneath the rear drivers side passenger.

It is supposed to be mixing 20% but it has to be less than that as I can use 180 litres of diesel and still have some gas left over. Next service he will increase the percentage a little.

I'm very happy with the kit, good performance increase, good economy increase. I highly recommend it, you won't be disappointed.

I went this way because I wanted just a little more power for towing. When we increase the gas percentage it'll give even more power, he is also going to program it to inject more gas when running high boost levels so basically when overtaking it'll get an extra boost.

He wants economy figures first though before changing anything from the standard configuration for my model vehicle.

We've done 3000kms with it so far, no problems.

Jacks,
How much did it cost you and where are you from?

Jacks,
How much did it cost you and where are you from?

All up $4500 including exhaust modification, the kit and installation.

My installer was Bert from A & D Automotive in Mackay, QLD. The kit used was from: http://www.dieselgasaustralia.com.au/

We got I think $2000 back as a government rebate, so the real cost was $2500.

Cheers,


Jacks.

would be keen to hear your new fuel figures mate. tank range, that sort of jazz!

Roughly 20 litres of gas is giving us an extra 250-300kms of range (using 180 litres of diesel). I havn't kept numbers prior to the gas, but I installed it for the extra power. The economy benefits for me were just a bonus.

LPG Injection

Hi Jacks1071, Jimi and Steve Del,

I have just joined the pradopoint.com group and glad to see some discussion on LPG injection, as I had my 2003 Prado 3l TD auto install, late Jan 08 and I am keen to swap my experience with others and share my data for those thinking about getting it.

My install is the same as Jacks1071, the DieselGas Australia system installed by a company in Ballarat, Victoria. Cost of the install was $4500 including the exhaust re-route for the 32l LPG tank located under passenger seating area, Victoria rebate is $2k, still waiting for check to arrive? I still have my both my diesel tanks.

Although my install is less than a month old, I'm keeping figures to monitor the system, and I guess I'm after fuel economy gains as I like to tow my 1.5t caravan (pop top) at a reasonable cost with all the benefit my Prado will give me, when I do the Oz trip.

Below I have the my economy figures:-

Experience 1 - towed 640km (@~107km/hr ave, bit quick really) used 97l diesel, 8.9l lpg = 15.2l/100km diesel, 1.4l/100km lpg.
Experience 2 - city driving 258km using 31l diesel, 2.39l lpg = 12l/100km diesel, 1l lpg
Experience 3 - city driving 456km using 54l diesel, 11.86lpg = 11.8l/100km diesel, 2.8l/100km lpg

My consumption prior to install was 1300km of city driving out of my 180l diesel = 13.8l/100km, so I have reduced diesel consumption by 2l/100km (city driving) using small amount of lpg (except for experience 3 - not sure why?).

Due for 1500km service on installed system end Feb 08, and will collect more details and discuss with company regarding diesel/lpg ratio and try to improve consumption further if possible.

Jack1071,

Have you any advice on potential LPG ratio adjustment I can use prior to my 1500km service, ie. should I request lpg ratio increase, have you notice consumption improvement with any adjustment you may have requested.

For anyone wanting my dyno sheet, provide me you e-mail address and I'll be happy to forward it. In summary, it reveals 12-14% improvement in power/torgue.

Regards
GarryN

Re: lpg injection

I have a 120 series '04 TD4 GXL Had dieselgas Aust Gen4 system fitted 16/10/08 at ODO 109586KLMS ODO now reads119,362kays,=9776 on Diesel/lpg.
In my opinion, You don't seem to notice a real lot of difference, it seems to go better, but, when you look at the speedo you have to keep backing off the throttle!
Once you get over that and control the speed (cruise just under100 on open road). I have 10 examples recorded and show some below(if anyone wants more I can provide.
1st fill after lpgfitted - 596klm/84.49ltrsdiesel-14.54ltrsgas=14.17L/100 (Towing 1478kg van for approx 40%) i.e Diesel/gas ratio17.2%
8th " " " - 1262klm/142.82ltrsdiesel-23.6ltrsgas=11/3L/100 ( not towing) Diesel/gas ratio 16.5% (222Klms without gas)
3rd - 544klm/ 72.9ltrsdiesel - 9.62ltrsgas = 13.4L/100 (90% towing van) diesel/gas ratio 13.1.

I found that the best time to fill gas is first thing in the morning when all is cool, on my first attempt I could not get any gas in the tank at all! it was a hot day 36deg. and had been towing for 6 hours.
The gas tank is fitted beside the modified muffler (looks like a motor bike Muffler,throaty sound,not too loud,tank is 32ltr water capacity i.e. 80% gas max fill in good cool conditions That is 25lts gas,most I have got in is 23.6ltrs. I reckon full tanks range now to be 1400 -1500 not towing and 900 - 1000 towing.
Have not done any other mods due to lack of finances but would love to fit Snorkel and larger diameter exhaust.
Cost was $4000.00(Got $360.00 off by signing up at caravan show) and $2000 back from The Feds.
Having the 180 ltr tank is a bit of a disadvantage in one way due to not having enough room to have a gas tank the right size for the diesel tank.
I feel the biggest advantage overall is with the extra torque when towing.

Would welcome any other feed back

Regards

Gregor

Re: lpg injection

Hi guys - I would just like to point you in the direction of the thread on Intercooler upgrade for the D4D with some interesting dyno data on my O7 VX with LPG/Diesel and intercooler fan. Other threads on LPG/diesel are worth a read as well.
