Hi all,

lm thinking of installing LPG on my LC 80 series, the tank size is 110 ltr and l wanted to know if anyone has, or knows what l can expect in mileage from this LPG tank.

Thanks

Hi there Barney,

We have a 50litre LPG tank on a V8 Landrover Discovery and we get about 250 ks highway driving on a tank, towing a 17ft Jayco caravan 150ks. Hope this info helps

I think ours was 110lt...but 80 % capacity allowed around 90 lt or so. Average town km were 420km.......

its worth having it on them....we sold ours last yr....they are guzzlers of the gold!! I tell ya what though....its cheaper running the Navara on diesel then it is the 80 series on lpg. We averaged $50 a week in lpg and $35 on diesel.....now it would be $80 to our $50....

oh yeah....when loaded we would get 19lt /100km and worse case we had was 28lt / 100km between Innamincka and Bordsville....and when we sat it over 107kph on the tar......

would also put $20 of ulp in every 5 or 6 weeks so she could start up to......

they lose pwer but what 4wd doesnt on lpg !!LOL!!!

our tank took over the aux. tank so we only had the 70lt left which would give a total of 700 or a bit more km on highway.

Cheers,

laura

I can't comment specifically on the 100 but can offer this advice.

The older style LPG systems did rob a lot of power and use a lot more fuel.

The new Sequential Vapour Injection system only increases consumption by 10% and power drop of about 10%. This is based on my testing of our V6 Courier. You will struggle to notice the power drop, I only established by using a stopwatch to time in gear acceleration.

Look up Parnell LPG and give them a call as to how well it works on the 100.

Regards,

Jim.

Jim,
this could make sense cos ours may have only been about 3 or 4 yrs old (?????) and was quite sluggish compared to ulp....never did any testing though - just put up and shut up about it - figured it was slashing fuel bill by 50% so that was ok!!!

the power loss is hard to compare it to something....
.....going up bulli pass up at wollongong I would have to be in 4th gear on a good run and at one part would have to put it back to 3rd but then 4th pretty soon after; where ulp would be 4th easy the whole way and even 5th near the top if trucks didnt hold me up.
The navara does it easy in 5th.
But if the 80 series was loaded we would always switch to ulp for hills just to get up without holding up traffic!!!!

Jim,
I disagree with this. I have the 'older' style system on my 80 seeries that uses an Impco mixer through the intake between the air filter and throttle body. It makes just as much power on lpg as it does ULP. Las time I had it dyno'd it was making 52kw at each wheel. Thats on an independent 4 wheel dyno.
I think the lpg consumption comes down to the quality of lpg sold. If the mix between propane/butane is not right then it can either give more economy/power or less. Any way we may be riding donkeys the way things are going...........

Previous vehicle was an 1994 80 series with Impco Lpg = 90l tank , installed 1997.

Towing van (freedom 17' poptop) to Broome average 3.3km to litre and around town best i got was 4.5km to litre.

One disadvantage is the need to pull up at every service station on a trip in case the next town has no LPG or pump is out of order.

Definite drop in power on LPG going up hills with my unit, and I switched to unleaded for the hills.

Be sure to check with installer on steps to take to help avoid back fire (ignition leads, no washing down of engine , spark plugs).

Mine backfired on way to Broome and blew out the air flow metre ; left me stranded 170kms from Kununurra.

Pedro,
Did you have the BFS (back fire sock) installed?

Touch wood mine has never backfired.

Rob,

The advice I have been given is that with the old system the car is tuned to run on LPG and hence there is a power drop compared to when it is running purely on ULP. In your case when running on ULP, you are driving a vehicle on ULP tuned to run on LPG. Whilst you are getting similar figures on both, it less than it would previously have been.

With sequential it is possible to get greater power out of LPG and a similar state of tune to ULP, therefore an overall power gain on both.

Anyway, that's the way the bloke at Parnell explained it to me.

Regards,

Jim.

Hi the fuel figures vary a lot from various accessories like tyers, auto or manual,
roof rack ,lift kits ,suspension and all the other accesories you can bolt on to in crease the weight.

My 80 gets around 350klm from 90 litres usable from 115 litre tank around town stop start short trips.

On a steady highway run 100/115klm per hour over loaded with gear on the roof rack 420 klm from 90 litres.

Towing an off road camper about 330klm per 90 litres.

As for loss of power not noticeable.

I have mine Unichiped with dual mapping and now have more power by about 5kw running on LPG,and runs alot better.
The best way with lpg is what it will cost you to do 100klm.
Say compared with diesel.
At the prices YOU can buy it for on the day
Say a Diesel prado uses 10 litres per 100klm@$1.60=$16
My 80 on a run uses 21.4 litres per 100klm@65cents LPG=$13.9



I only ever made one mistake
and that's when I thought I was wrong!

Thankyou to everyone how replied.

The info supplied is certainly valued and lm looking forward to having the tank installed. l believe it is a sequential system and will cost $2800.00 l plain on keeping this vehicle for another 10 years since l purchased it new. (last of the 80 series 1997 with only 186000 on the clock) the main tank is 95 ltr so with the lpg it should give me a good travelling distance and heaps better economy. The vehicle is modified, draws, fridge, ARB bar, winch etc etc, and l recently had it weighed with 100 ltr's of ULP in tank, the weight was 2.74 ton and this is without the beer and other equipment. lm doing the Simpson Desert in September, so now l will have find out my last point for LPG.
Thank God max trax dont weigh to much.

Cheers

Barney.

Hi Barn i did the Simpson last year. Depends on which way you go.
I went west to east. the last place i filled up with lpg was Peterborough
in SA and kept the lpg as reserve only.I carried 5, 20 litre jerrys
2 on the back 2 on the roof and 1 inside pictures on my profile.
I filled the jerrys at Mt Dare and empty'd them daily.
Used 140 litres ulp from Mt Dare to Birdsville 560klm from memory
with out looking up my records.
carried the extra fuel just incase you have to turn back due to the weather and Eyer creek could have been a big detour.
If you are doing an out back trip where you need to reley on lpg
dont leave it to the last town
as i have found out the pump is broken no gas.
you just have to do a little planing.

Hi Barney

I get 20l/100km in my 2.7L Hilux petrol... And yes it has been tuned

The savings work out to be about 40% at current prices

I've got a 60L usable tank (total around 67L i think), so I'm getting around 300km a tank in the city and not much more in the country.

After I had the LPG installed, I purchased new Topgun Max300 leads and platinum plugs. These were required to prevent backfiring in the airbox. Cost was about $300... You should also get the auto oiler installed when you get LPG fitted (about $100).

The moral of the story is: when you get LPG installed SPEND the money and get new plugs AND leads and you shouldn't have too many worries... Run it on petrol on start up and switch over to gas once the engine warmS UP (a couple of minutes).

Expect to only save 30-40% on your fuel bill and expect some hiccups.

Will.

Gas injection gives my 80 series 20L/100km too, pushing a slightly heavier truck.
Backfiring isnt an issue with gas injection, but quality plugs and leads are always a good thing.
The system is totally automatic... you start it up (on petrol) and you just drive. When coolant reaches 40 degC and revs are off idle, it automatically switches to gas without any hesitation or change in power.
My fuel bill has halved if not more.
Used:
16L/100 on ULP @ $1.59
Vs
20L/100 on LPG @ 62c

Cheers!

Hi mate,
I just had my ULP 80 series converted to electronic gas injection. Its an Apollo system which is what my mates at Maquarie 4wd center recommended. It has a converter and 6 individual elec solenoid injectors and thats all i know really apart from it being totally automatic and has cut my fuel bill to half, if not less than half without losing anu power- best thing i ever did.

I had a 90L tank fitted where the sub was. I reliably get 390-410 kms combined city/fwy driving from 70-75L of gas.
This system cost $4,600, minus the govt rebate it cost $2,600.

If i knew a 110L tank would fit in place of the sub tank without restricting ground clearance i would have gone with that- cant have too much range! But 110L=110kgs plus a spare wheel carrier plus spare wheel adds alot of weight over the rear. So budget in upgraded rear suspension if you dont have it.
Go for it and you wont regret it.

Just to add to my previous post, i calculated 20L/100kms thru getting 400kms from 80L. However i get 400kms from 70-74L (never run her dry) so thats more like the 16L/100kms which i got on ULP.
Pretty amazing to find with these ecu controlled injected systems you use about the same amount of gas as you would ULP, except gas is 60% cheaper.

Spoke to the company who installed my gas system, asking about fitting a 110L gas tank instead of my 90L to an 80 series. He said that the dimensions are only slightly bigger so no dramas, but it needs exhaust mods to make it fit. No big deal but something to consider and find out more if you wanted to go that big. Plus of course suspension upgrades and a spare wheel carrier.
Hope this helps!
