LPG economy.

[sphell]

Hey guys i know a lot of you have your cars on gas. I'm interested to know how many km's you get out of a tank of gas and how big the tank is. Cheers

[EFFalcon]

67litre usable.
full tank gets me around 400km with 'the usual' driving
if its all freeway then its up around 550km.
thats pretty much full to bone dry.

[niko]

its roughly 12-15/100 litres pending tune and motor

[trick_xd]

67 lts is full and with around town driving i get about 350km with a Tickford Style gas kit (spud at throttle body) I6 auto stock

67 lts is full and about 430km with a Impco gas kit I6 auto worked

65lts is full and about 300km I6 CFI

[peterban]

70 litres gets me anywhere between 420 and 520 kms with a 5.0L V8 AU11.
Impco system

Depends on what system you install
There are 2 different systems available
1) The old carby system
2) The new vapour sequential injection system
( There's also a liquid injection system , but it's not available in Australia yet. Same fuel economy as petrol ,and more power than petrol. Holden and Ford will be fitting it by 2008 )
How many K's / litre do you get now ?
With the old carby system you'll have about 25-30 % loss eg if you're now getting 8 k's / litre now , you'll get 51/2 to 6 k's/ litre on gas
With the gaseous injection system you'll have about 10-15% loss
I don't know what they're charging at the moment , but a couple of months ago the prices were around $21/2k for the carby set up and $31/2 k's for the gas injection system
As far as I know the best sytem for the carby set up is Impco and
The best systems for gaseous injection is either Prins or Tartarini
I suggest you go for the injected system
It's a more accurate metering system
So firstly , it's a much cleaner ,environmentally sound system - you're putting a lot fewer pollutants into the air
Secondly it's more economical ( more k's / litre ) so if and when the price of LPG rises it'll still be cheaper to run than petrol
Thirdly there's also slightly more power than the carby set up
Fourthly , no chance of backfire ( with possible damage to your engine )

[EFFalcon]

in terms of fuel economy, LPG injection as liquid will still have a loss compared to petrol, its just in the nature of the fuel.
power on the other hand is correct, can go up.
but give the petrol car a good tune up with an aftermarket ECU and the power would be very similar.

i get 400km city driving and 550km freeway. from a EL tickford gas.

[Bass Crazy]

With 64 L or gas I get 400 around the city if drive a bit rough, 420-450 if i cruise her. Not sure on the freeway, but something more then 450 id say

Oh, and thats a basic OMVL system, bbq ring mixer, no electronic control and Simons slack backyard tuning.

[alecrain]

Hi, I get just over 400 kms on a 67 ltr. (~16 ltr/100kms)tank in a mixed mode (freeway and city).
it's less than $30 dollars to fill up (provided you found a cheap LPG station, I recommend motormouth.com.au price check in your neighborhood))

[Fairlane]

AU2 E-Gas- 92L tank with 80% usable

450 Pure city
500-500 Mixed town/Highway
650- Freeway

[Psi-Pop]

Mine fills to 55 Litres and i just get on 200km of normal drving or atleast 250km of Highway cycle in a EF 6 Auto. Somethings wrong somewhere and i just cant be bothered forking out the money to fix it even though all see the savings straight away.

[Tiga_EL]

I get 350km to a tank, but if i run it to the very end it gets 400. also on a factory tickford lpg system. I think its a 68L tank

[MacGyver]

I have 47l useable and get 350 on Highway and 250 around town. Just a basic OMVL system with a Tickford LPG ECU.

[V8R]

68 usable and i do ~380km around town and fill up with 62L. thats in an EF auto sedan with an airod ALS mixer system. would push over 400 i guess.
roughly 16l/100 on gas and 14.8 on petrol for the same driving.

[frost]

85lt 83 usable - ust to get 500 around town and upto 650-700 on highway with a BRC converter and geneirc ring on the TB. Mark gets about the same I think

[lcdownes]

From bone dry tank.

52 lt gets 300-320 all city driving.

[tezar]

60 odd litres 250kms 1986 xf fairmont ghia impco 300 gas system going by the previous posts there must be something wrong! the ecu at the passengers feet is it marked for lpg? as a mechanic replaced it after it got wet from a leaking windscreen maybe thats the cause

[sphell]

Thanks guys those figures helped me a lot. I ended up buying a 2005 Holden Combo. Fuel wise it works out about the same as a Falcon wagon on LPG but with a hell of a lot more space.

[EFFalcon]

what about for passengers? :P
