Please do more research befor posting.

1. Direct injection, its still a new technology, mostly coming out of europe not many cars have it so it's far from 80% you claim, about 20% of models have it mainly from europe so overall maybe 5%. Diesel would have a higher take up then direct injection at the moment. This will change in the future as the technology becomes cheaper. No Australian car has direct injection.

2. On LPG fuel consumption will suffer by up to 30% and power will suffer by maybe 5% if the car is tuned properly for gas. Remember that gas has a higher RON rating then any petrol sold at a servo.

3. Brazil has the worlds highest use of ethanol because they are the worlds largest producer of sugar cane and they spend the money to make ethanol in the last oil crisys of the late 70's.

4. Ford makes a LPG falcon and has done so for years, just go to the Ford web site and have a look.

LPG is a good alternative if you drive lots of KM and you have a large car, it is not the answer for people that get 11L/100 and drive 15,000KM per annum, it takes too long to recover the cost of installation.

Well i already said where i got my finding from, news on TV & actual experience, not google.

So do you have a gas running car?

80% of new cars, i didn't said 80% of cars

And btw Lexus had out sold BMW & Merc combine just in U.S alone, so i'm not quiet sure how correct it is when you said direction injection are mainly Euro cars.

Lets not forget all the new Mazda, Nissan, Subaru and of course Toyota are coming out with DI.

But hey i do agree with you that gas is only good for those doing long mileage per year. And i think that was my point.

Peace out

I ran ethanol blend for 3 fill on a trip to Vic and back to Qld B I G mistake lost power while passing a few times could of been dangerous Blocked up fuel filter ( no idea why it was new filter before trip) also tried running normal unlead for a couple of weeks another mistake

I was talking about models and not cars sold. Lexus has direct injection but so does SAAb, Alfa, Peugot, Renault and Citroen.

Also I will stick to the fact that there would be more diesel cars sold world wide then Direct Injection.

Also coming out and are available right now is a big difference.

I have had a number of LPG cars including a 390 ci Gas Research XE that run 11's.

Peace brother.

I have seen especially modified LPG engines run at higher compression which actually have 15-20% more power than their ULP counterparts...

I had issues with my origional EF Falcon on gas in the early days. Running on the dyno and fixing the issue I found that the difference between LPG and my ULP was about 5kw from about 100kwatw..so yeah 5% - and thats not theory thats what I got.

btw...diesel since it was comercially released has always used a direct injection system and would make up the majority of cars on the road using this system...

i remember in studied enthanol in chemistry class...

ethanol burns quicker thus ull get less milage... it has a higher RON rating so maybe it evens out, i dunno... i produces more heat on conbustion aswell...

but! you'd need lots of land to grow sugar cane to get sugar to ferment to create ethanol which then has smelly organic waste to dispose of...?

it is a renewable source, but where are you going to get the land and water to grow that much sugar cane to cater for the whole worlds increase in demand for ethanol? and theres the problem of people drinking it aswell... it taste like rum...

There is a huge difference between, indirect injection diesel, which has been around for a long time only phased out in the last 15 years, then you have direct injection diesel, then you have common rail diesel and then you have individual high pressure injection like on heavy trucks where the fuel is pressurised by an additional lobe on the cam shaft to inject fuel at incrdebly high pressure. Remember that car diesels are still about 5 years behind trucks in diesel design.

I see your point bobz & i agree.

Just don't confuse members here with your straight gas carby. You giving them false indication that gas converstion on an injector car can do 11sec

not sure what this has to do with LPG
