Mileage on gas?

copper1 · Guru

Wow that's 36lts every 100km I would not be happy with that, and given that gas has crept up in price over the years, what was your usage before the conversion??? might give you a better idea.

hmm Given my own current Ford is LPG only(factory installed, new), I suspect the fuel consumption would be about right!

My fuel consumption over 16000kms averaged 23litres per 100kms towing a lightweight Millard Poptop. Consumption when not towing is around 14/100 kms in city. Because of the paltry 80 litre fuel tanks, I installed another 80 litre tank to enable touring thru the outback. Only availability problem was at the SA/WA border Village servo where the pump was out of order/ out of gas. Highest price per litre encountered was $1.44!!!!!!!

Dissapointing I know, but I think that figure would be near correct

LPG has less energy (30 - 40%) than a similar amount of Petrol. As result, you will get less (30 - 40%) kilometres per litre. This then is a simple equation; On petrol, if you used 15 litres per 100km, then on lpg you should be getting around 21 litres per 100km (40% increase worse case scenario). As someone else said, what was your consumption BEFORE the conversion?

I'm guessing it would have been around 20 litres per 100km given the rig set up you have, so you should expect no worse than 28 litres per 100km. LPG does affect performance in the same way also but as it's at least more than 40% less to buy than petrol, the numbers should add up for you. Something sounds wrong with your 36 litre estimation. Maybe get it checked out by an independant installer?

The advantage of using LPG as a motor fuel is its potential for cost savings. It can be up to 60 percent cheaper than petrol, litre for litre. Other advantages are reduced exhaust emissions and potentially longer engine life

Cheers!

I have a 1998 Prado on gas/petrol an am pushing at the best of times to get 300km out of a 60lt tank of gas. Strangely enough my 60lt tank of petrol is the same so have to keep an eye on things when in the middle of know where only having approx 500km range with the Den on the back and approx 580km range with nothing in or on the back.

I have always said I have the most uneconomical tug on the planet.

Strange thing is a mate has exactly the same tug only all petrol and in his 60lt (Reserve) petrol tank can get 400+ km not towing.

Flick, We changed from our 4500 Patrol on LPG TO the same wagon you now have ...V8 Cruiser....

We had a 100ltr LPG tank which means you are really only getting a fill of 80ltr (i.e.80%)...

With out towing (and mainly motorway driving from Strathpine to Nudgee servo area)..we were getting approx 400km per tank (pretty consistant).

Towing our 23ft Windsor....Hmmm...dam thing dropped to approx 200km per fill.......

Our biggest concern was being out in the boon-docks and running out of LPG as the reserve tank for petrol was only 25ltr....and that doesn't get you to far when towing...then coming across a servo that sold LPG and they had run out.....can often mean sitting where you are for 4ish days waiting for them to be filled.

Now with out LPG using the Cruiser we are getting approx (and pretty consistant)...6km per ltr when towing ...so taking the price difference into account...We are still about a 1/3 better off....

PLUS...The Cruiser tows it effortlessly.

I see that you are in Brisbane as well,,,,We had our LPG service by Motor Gas conversions in Lawnton....They were very good & know their stuff.

************

ONE QUESTION......What was the milage on your Cruiser when you had it installed....??? I have been toiling with the idea of getting it put on this cruiser as they tell me that it will take 2 x 50ltr tanks under the drivers / passengers seat and not have to touch my petrol tanks in the back.

Normal driving on LPG (NOT TOWING)...I was happy with the 400km per tank...

My Pajero is running on dual fuel and when towing my 21 foot van I get on average 250 klm on a tank that holds 64 liters of gas and with vehicle only around 350 Klm per tank
the Pajero has a 3.8 litre motor and the difference in performance between LPG and Petrol is not noticeable. Petrol consumption when towing is slightly better than Gas but not a lot,
I have fitted a quality brand set of headers and fuel consumption has improved and so has engine performance.

I`l through the cat amongst the pigeons , I have been going through the same thing this week .
I have a Toyota coaster with a 308 holden motor which I used to tow a tandem trailer with my race car in it and never worried about the consumption too much . Now that we intend to travel OZ I decided to do an economy test and to my horror I was only getting 250 Km out of 100 ltrs , not good. I took it to a so called gas expert the other day $350 later and its worse than when I took it in ,so I went to Ebay , found a distributer for LPG parts got the mixer etc for $500 which was $1000 cheaper than the gas guy and will install today. Is it just me or do these people take advantage just because they can. Buy the way I shound be getting around 4/4.5 per ltr so they tell me for the weight that I am pulling (3500) kgs , I presume a landcruiser and caravan weighs simular.

Flick....I did mean to mention that like Aussietraveller......That the difference in performance between petrol / LPG.....was probably zero....infact I often felt it ran better on LPG....than on petrol.....

Mate has a 2006 V8 Cruiser Duel/Fuel, He gets around the 260 - 270 Klms from 90 ltr Lpg when towing 2450 Kg Van --- And around 350 - 380 k when NOT towing,

I have a 2011 Holden Colarado, Ordered New with Lpg compatable Engine, The Gas system used was the 'Impco' Direct Injection, and for full warranty, and service reasons GMH Gets all there Dual Fuel Fitted by HSV Holden [ the race car people,]

They tune the engine to mainly run on LPG, hence ! the consistent figures I have been obtaining are Not Towing -- LPG 14-15 L/P/100 -- Petrol 13 14 L/P/100 - I always drive on lpg until the empty alarm goes off, and when I fill the tank from empty it takes between 73 and 76 litres, I also tow a 2440 kG [ fully loaded ] Lotus Caravan, and get around 290-310 Klm from that 73 ltrs of lpg, -- I notice No difference in power between the 2 fuels, maybe ?? the Gas in a little more responsive. - I am happy with it,

As for all Lpg vehicles it is Important that they are kept well tuned and serviced by ''Reputable LPG service centres,

MMMMMM if that's the case I will stick with our 200 series Landcruiser 4.5 ltr diesel, average 12/13 ltrs to the 100km buzzing around town and 19/20 sometimes 21ltrs to the 100, towing our 23' van.

Far out, none of that sounds very promising! I'm soooo disappointed, it's not funny!
I really can't give you much info pre conversion as we'd only had it three weeks whenwe cconverted it and this is our first big trip towing the van (apart from a short run, Narangba to Blackbutt). Usually around town we've been getting 300-350ks from gas andaaround 400-450 on petrol. We drove to Yeppoon after Christmas and were really impressed with both petrol and gas. We got around 500k on gas and around 600 on petrol. I realised it wouldn't be that good once we put the van on, but Geez Louise, it cut it clean in half! As for petrol, well we haven't got an accurate reading on that as yet because we've only used it between gas refills, assuming gas would still be cheape. Now, iI'm not so sure, especially considering petrol is 10-15 cents cheaper here than Brissy was when we left.

Also, to add insult to injury, it's soooo much more gutless on gas, I mean really gutless. We test drove sooo many cars and Ikknow you can't tell much in a 15 min drive, but of the 4-5 dual fuel cruisers we drove, there was no nnoticeable difference in power. This thing is gutless even without a load! I'm sure if it could, it would shake with fear every time we point it's nose at a hill!

Thanks for the advice, once again. This place has been a godsend since we stated our trip a few days ago.

Oh and by the way... Where the heck are all the grey nomads? If they're out here, I'm sure they're hiding from us! Lol. We've pulled up every night hoping to meet all these amazing people and absorb all their pearls of wisdom and all we got wassome rand om dog come and pee on my tyre! Lol

Thanks again.

Those figures for LPG really surprise me. I don't think I'll ever complain about my mileage ever again.

Diesel esp turbo diesel is very fuel efficient..

That's our experience also Julie! Unless you're travelling in a group, sit outside your rig everynight saying hello to anyone or park up in a caravan park for a week and get to know your neighbours, you won't see many people. We too have been disappointed with that aspect as well. We set out on our trip in November and wherever we pull up (QLD, NSW, SA, WA) there have been very few people and those that are just go inside their own rig and shut the door.

Don't worry mate, it's not you! (Awaits the inevitable "You've got to make the effort comments")........been there, tried that!

Cheers

PS Where is your trip taking you? I gather you're from Brizzy (we're from Hervey Bay) and we're currently in Perth.......

oldbobsbus · Guru

Gee the mileage some of you are getting sure makes my 5.3k to the ltr look good in the 9mtr Hino with a car intow..

Paul and Val,
We're currently in Albury as Russell's uncle died so we're here for a funeral. We're leaving today and hoping to head to Omeo after lunch. It's not that we feel we're being ignored by others, there just doesn't seem to be any others around lol. We're smokers and don't smoke in our house or van, so We're mostly outside anyway. I'm thinking maybe it's just the wrong time of year forgrey bnomads to beoout, maybe? It is school holidays after all. Anyway, here's hoping this next leg of our journey improves.... Though sadly I don't think our fuel situation will.

The RAA in South Australia are advising people to think twice before converting to gas, they claim the price of gas has risen to a point where there is virtually no cost advantage to be had in using gas.

Flicka9736 · Veteran Member

Santa, I'd have to agree, sadly.

Jayco Gypsy · Senior Member

Just a bit of trivia on my own gas experience. I don't know how to convert figures to the Klms/lt. With the VE Commodore 2006 model, towing a 13ft Jayco I get the same towing distance on gas or petrol. 300kls to a 70lt tank. Gas and petrol tanks are both 70lt each. Around town I get 500kl again on both tanks. This car was manufacture with gas by Holden in South Australia. Consequently I rarely run the car on petrol. The manufacture claims 5w (what ever that means) less power on gas. Haven't noticed any difference power wise when driving myself.
