Look at the fuel prices, even people earning a comfortable wage would be having second thoughts about buying a 6 cylinder petrol car. With fuel tipped to hit $1.50 a litre by January theres not much sense in buying big if its going to sting your wallet.

Why not make the 380 as LPG only? Have petrol as a optional extra. I mean 95% of fuel stations sell it, its around 39-45 cents a litre before the discount dockets. With factory LPG you only lose around 5% power and 1% torque, I'm sure most people are not fussed about a tiny power loss. Plus with bulk buying of gas system I'm sure the price would be better than the $2500 extra it currently costs.

My Magna has factory gas, I'm going to keep it till its wheels fall off. Filling her up for $25 and getting 450-550 out of the tank is incomparable for a $90 fillup on petrol and getting 650-700k out of it.

Thats a very good idea. Although its not for everyone. For example i drive my car for work and I need space, therefore a sedan with a gas tank is not an option. And since the 380 is not coming in a wagon variant as far as i know, then it doesn't cater for my needs. Thats why I have bought a TL wagon and gassed it, probably hang on to it for a long time too.

a dedicated gas setup would be sweet :D

Dedicated gas replaces the petrol tank =no space lost.

The dedicated gas TL magna still has its gas tank in the boot.

the lpg mono fuel model TW ES has closer to 9% less power and torque.

Fart in the tank:bowrofl: 9% power gainlol Thinking aswell getting LPG, To my work mates im a taxi service now and with the gas i'll be 100% taxi:badgrin:

straight LPG cars are good for city folk but unfortunately you still can't get auto LPG in a lot of small towns, and the country sites that do sell it are rarely 24 hours.
I used to own a falcon that was straight LPG and will never own a straight LPG car again, I have a dual fuel magna now.

how would you go with the motor tho because doesn’t gas ware out the motor alot quicker cos its not a lubricating fuel unlike your normal petrol that’s why even if you have duel fuel every so often its best to change over??

With allot of people going to LPG, I can see the price of gas rising :confused:

Actually it's the opposite, gas engines generally last longer than petrol simply because LPG is a cleaner fuel.

correct however any gains there are majorly outweighed by the fact that gas is.. well gas, and petrol is liquid. Car engines need the liquid state of petrol on start as a temporary lurbricant untill the oil is circulated properly. Its for this reason that alot of duel fuel setups will automatically start the car on petrol even if you have it set to gas.

in theory a proper LPG setup should last longer then petrol, but in reality it rarely happens

What I would prefer to see is development of a high performance DI-D engine.

Yeah thats a old myth. Petrol does not lubricate very well to begin with, afterall its just burnt. Gas is a lot cleaner, no gunk.

if its a myth then all the toyota engineers seem to believe it because with the toyota duel fuel setup it automatically goes to petrol mode whenever you start up your car and leaves it there for 2 minutes or somehting even if you have it set to gas

The main reason duel fuel setups start on petrol is because they can't start on gas. Ford had a little trouble with their dedicated gas cars. They had a fair bit of stuffing around to get the engines to start on gas only.

I've been told that in some cases modern cars can actually gain power from LGP due to a higher octane rating. Something to do with the timing............

my dual fuel setup starts on petrol and then switches to gas
i find it important to make sure you use petrol some of the time to keep things running along nicely but at 230.000 ks no problems out of the ordanary yet

apparently you can run higher compression with LPG

Definately, some of the new generation diesel cars i have driven perform pretty damn well, but more interesting is the Diesel and LPG duel fuel, the LPG is injected with the diesel, as diesel is ignited by compression, not via spark plugs, apparently this is giving some big power gains, as well as improved economy via the price of LPG

Toyota's 4cyl outsells the 6cyl. Mitsu need to bring back to 2.4 to the Australian model. The Galant uses it, but ofcourse mitsu stuffed themselves up by calling the car the 380...

What a brilliant idea to have a dedicated LPG 380 as an option, I know I would buy it in a heartbeat over the petrol version.

Yeah but with the current weight of modern large cars, a large four cylinder motor will chew nearly as much fuel as there 6 cylinder counterparts and be down on power in a big way, just not worth it.
If the cars went back to weighing around the low 1300kg mark then it would be feasable.

I had a look at the new Rodeo, and the four uses 12l to the 100klm and the V6 uses 13 to the 100klm.

Yes it should. :D

i guess if fuel prices really started becoming obsene MMAL could look at introducing a "Mitsubishi 240" which i reckon actually doesnt have that bad a ring to it... but it would need to be a truly excellent engine. 2.4ltr with proper MIVEC on it would be a must and 140odd kw's of power minimum to get it up around accord euro power levels would be a must!!

maybe this is something MMAL could look at around the 380's mid-cycle upgrade in around 2 or 3 years time? A 240 and 380 sedan line-up could make a really really good combination...

interesting :think:

my work ute is a dual fuel XH falcon and the fuel pump in the tank stuffed up. the noise was unbareable so we disconected it. we left it over night and when we went to start it the next morning, it wouldn't start. after around 15 minutes of cranking, we opened the back up and conected the pump and it started first turn of the key.... my work is SO CHEAP....now we have a dodgy switch to turn the pump on and off :nuts: this can't be legal :confused:

hows this for a combination....

My 86 magna is dual fuel, carbied, and automatic!

my head gasket is leaking so i get bugger all compression, and the carbie needs a reco....
so it takes $37 to fill at $0.59 per litre...(cos in tassie there is only one distributer or something), and it gets me only about 380km! Ive pretty much run it only on LPG for the past 3 years, and now it wont run on petrol cos i havent fixed all the stuff thats wrong with it... Any way I reckon if i get it all fixed and tuned correctly it could last a few more years...
i might experiment with cam duration and timing, mabey shaved (or EFI) head to increase compression....

i agree with someones suggestion on a direct injection diesel engine variant -i'd like to see that.
or maybe a dedicated 2L LPG turbo engine (or with a clutched supercharger or something).
That'd have decent economy and power i'd imagine- and it'd be light and fit into a lancer.

Not sure if anybody has read this but it was published in the Advertiser on 2/9.

'Mr Taylor said the Australian versions of the 3.8-litre V6 would be fuel efficient and claimed that tests had returned better fuel economy than Ford was claiming for its new six-speed automatic BF Falcon as well as figures for Camry and Holden's Commodore.'

From my understanding the new falcon with the six speed auto (that is the fairmont & XR) has an average fuel rating of 10.2.

450 -550 out of a tank? I only get about 350 - 400. Mines factory fitted too. It's great filling up for around thirty bucks. I notice only a little power loss but i think the engine runs smoother on petrol.

Well I heard some bad news the boot of the New 380 is too small for a gas tank so Lpg is not an option. Inside information. :nuts:

:shock: Uh oh. If that's true that could be the first hiccup! Let's hope that's it.

The post about LPG running dry and hence needing dual fuel could not be further from the truth, the cylinders are better lubricated with LPG as there is no fuel was associated with petrol, that is as petrol comes into the cylinder it washes the oil off the bore and dries the cylinder causing wear, LPG doesn't do this hence it is hard to bed in a LPG motor as there is little if any wear to the bore.

Well it hasnt come out with LPG as standard so this thread can now be laid to rest
