Petrol V Gas

[Mont5.0]

Was looking for a run around falcon on LPG.
Whats the pro's V Cons for LPG powered Falcons? Is there a major power difference? With gas prices the way they are, is there really much of a saving compared to Petrol engine Falcons?
Ive only ever owned Petrol /Diesel motors, so have no clue on LPG.
Any input from Gas powered falcon owners would be appreciated.

Probably not *really* worth it, unless you go for EcoLPI in the FGs, IMO.
I have never owned a gas falcon, but have been in a few. You lose a bit of grunt, but you do save fuel.

[Brute 33]

What do you spend a week on petrol ?.....I cut my fuel bill by more than 1/2 ....and NO POWER LOSS .....

Incorrect! The EcoLPi produced more power and torque at a lower 1000 rpm lower than the petrol engine! They do burn more fuel but gas is cheaper so its works out nicely.

I have an EcoLPi and its fantastic. Really good on fuel and great all round car. I must admit though, the EcoBoost does come very close to the running cost of the EcoLPi especially when you factor in cheaper service cost of the EcoBoost. And of course you lose your boot space thanks to the gas tank.

I use the EcoLPi to tow my XR8 to the track, a job it does with ease and very cheap.

When you say No power loss, how is this possible? Don't the Egas motors (B series) produce less KW from factory?

[Ducati888]

Even with the old mixer systems on old cars you lose a bit of 'grunt', but generally LPG is put on big cars with big engines. How much 'grunt' do you need, that you couldn't afford to lose a bit?

I've got a 97 Prado on dual fuel. There's a negligible difference between running it on LPG or Petrol performance wise. Towing, it uses a lot of gas, and a lot of petrol too. Any way you do the maths, there is no way that LPG does not save me money. For newer cars with injection systems, I don't know.

If you buy a car that's already converted, there is no possible way that you can lose. It will always be cheaper to run it on LPG.

[Mont5.0]

I would be buying something that is factory optioned, not added. Not really keen on dual fuel, just a dedicated gas engine. It will be a B series.

[motorcycles4eva]

if it helps.. i have two clevo's .. one on petrol and one on lpg.
the lpg is only lpg and there is no powerloss. it actually goes well.
the petrol is duel fuel. yes..power loss.. either tune it for one or the other.
otherwise it will be a bit sluggish...

yes it did cut fuel prices to i'd say half.. but on the other hand, as gas is cheaper.. i accelarate harder.. lol..
so in my experience, gas is great. i've had not problems at all in the years i've had both...

Well in standard form the I6 petrol isn't exactly a power house, I can only imagine the Egas engine would be less powerfull. Anyone own both and can compare?

[Ducati888]

It's still a 4.0 litre engine, putting out about 190kw. How much power do you need for "a run around falcon"?

A Falcon on LPG will still have more torque and KW than most other cars on the road.

An ECOLPi has more power and torque than the Petrol engine!

[Hulsty]

Egas has same torque but lower peak power, dont notice it as I dont drive everywhere above 4000rpm.

Cost me about $50 for 400km a week.

I6 is pretty powerful, it powers my Territory around quicker than most SUV's.

myself on duel fuel using a vapour system I get power loss on gas, but only marginal.
If the engine is tuned correctly and the gas is of good quality the theory is it will get better performance.

Don't get hung up on it, as Ducati888 says the I6 falcon has more than enough grunt anyway.

more important questions are: what are you using in petrol per week now? or how many kilometres do you drive..

[Alan D Segal]

The EcoLPIs are awesome. I drove a G6 EcoLPI recently and was very impressed with it. Great car.

[Mont5.0]

Im not driving a lot of k's, but she drinks plenty. That being said it isn't stock, just seeing the pro's and cons of LPG falcons..
Im seeing lots of Pros for consumption v cost, but no cons...

[Alan D Segal]

If you're only looking for a runaround then there isn't really any cons and cheaper to run should be the biggest 'pro' you need.

[Mont5.0]

agreed. Was looking at associated costs, as I said have never owned LPG vehicle, do they require more maintenance, any special servicing etc....

I'd avoid an eGas Falcon, I've driven my friend's BF eGas ute and it certainly feels like its got no balls. I was getting about 15L/100km but we were doing hilly driving.

The EcoLPI would be the way to go if you want to go gas IMO, the mixer ring ones are unacceptable, way too much loss of power.

[HULK_I6T]

cons could be there are less around for sale. Hence these owners might think they are worth more.

Id compare the purchase price of a regular petrol (plenty on the market for sale) vs a egas (few and far between that arent utes)..

If there is a significant purchase price difference, plus different maintenence costs, thats a fair bit of petrol to catch up

If its late model, you might get the capped price from Ford.

EcoBoost for 15,000 kms was $245 and the EcoLPi was $330 I think from memory.

Also remember the standard price gouging during the summer months (blaming the northern hemisphere winter) where Gas will hit $0.90 plus for a couple of months.

[Mont5.0]

It will be 2nd hand B series Egas..

[Polyal]

Honestly for a run around you may aswell get a 4pot if your not going to some form of injected LPG.

[Mont5.0]

Really would like to keep it Falcon. 2 large kids and wife...

[Polyal]

So whats wrong with doing an install yourself?

Find a nice low km BF, get SVI system installed and its miles better than any eGas and only marginally as sophisticated as the EcoLPI.

I had a SVI system on my old AU I6 and if it wasnt for a family member bending the car I would still have it. It was awesome, no power difference and you couldnt even tell when the LPG kicked in.

Maybe look at Mondeo instead if you can't stretch to EcoLPI Falcon? Surely you could get a decently priced diesel now.

Forget dual fuel, its a **** of a thing, one or the other IMO.

I'm in the same situation and I think I have the same car and same system.

We have many turbo cars on liquid injection LPG and when tuned for the gas they make more power than they do on 98.

Any mixer ring system will rob some power and a dual fuel setup using a mixer ring will also lose some power while on petrol.

+1

I have a dual fuel BF wagon on vapour injected LPG. Economy is better than the basic mixer setup, can't notice any power difference to petrol, unnoticeable changeover between fuels, gives you options & flexibility when refueling on long trips etc. Bought it with the system already installed and very happy with it.

I will have to disagree, even though my setup was duel fuel it ran on petrol for stuff all, only until it was up to op temp.

I only ever kept enough petrol in to keep the low fuel warning off.

[Brute 33]

Son has a BF Mk ii XR6 ute Factory LPG and it goes really well and has been fantastic for him in cost saving, as a apprentice signwriter , not earning a great amount of coin ,it made logical sense , so much so that now some of his mates now own LPG powered cars as they would whinge about their fuel bills .....I have straight gas and dual fuel vehicles and see no noticeable difference in performance , providing you have a "Quality Installer" and quality equipment fitted , lots of poor brands out there and lots of sub standard installers as well , and last but not least there are only a very small amount of people that can tune LPG powered cars properly and believe me I have seen the so called "EXPERTS" try and tune LPG cars in both standard and modified set ups....

If you want someone to look at a LPG powered car that you want to purchase happy to help advise

EGas Falcons topped out at 156kw and about 370nm. About same power as an AU SOHC with more torque but obviously a heavier car.

The LPG system will need extra attention over a petrol engine as well as the tanks. You might find alot of 2004-2005 models for sale that still need their 10 year tank inspection.

I don't think the factory systems are prone to backfiring like some of the cheaper aftermarket dual fuel kits, but Ford gave them stronger rods just incase. I believe they take longer to start as well.

The best opinion though on running one will probably come from Mechanik who ran an eGas AU and BF2
