Lack of support from manufacturers, people are confused by conversions, government grants ended just as people became more aware of it and it smells bad.

 

Chappy here with the factory LPG Astra is happy enough with his but can't find a new car to replace it and is concerned that the government will raise taxes on it soon. He also struggles to find anyone at Vauxhall to service the LPG side of things despite it being factory, they alway tell him to go somewhere else.

 

It's not as inconvenient as it was for him to fill up but prices do seem to fluctuate quite a bit and he often turns up at the garage to find they have run out.

 

Having driven the Astra I found the performance drop noticable but not too dramatic.

 

It's Biofuels I'd like to see more of.

My sister had her ML 4WD Merc thing converted... lots of miles for the money, but the performance is shocking.. that said it's probably the car more than than the fuel?

 

edit : yeah she paid about £3k for the conversion.

Odd, my experience of it was that the fuel was substantially cheaper to buy but the actual MPG was lower, so you end up saving money it's not as efficient as a decent diesel.

Hmm..so for a cheap run around it's not really viable due to the install cost potentially being substantially more than the car itself.

 

You'd need it to last a good few years so you'd really want to be buying nearly new - which negates the idea of me having a cheap 3rd vehicle for commuting.

 

I wonder how difficult they are to fit or if you can buy DIY kits?

 

Ludicrously an age of Green awareness it makes more economic sense to buy an old Diesel knacker. Where are the incentives to get us commuting more greenly and cheaper? (Especially now LPG grants have gone)

Keep raising the prices but offering no solutions. :(

on a similar note; why hasn't bio-petrol caught on? all you need to do is grow it in a field and then add a few 'ingredients'.

 

Bio-petrol has a higher octane rating than v-power or super unleaded !

I have lpg on my Shogun. The performance isn't great. It does smell, but we have plentiful LPG stations in the North East - and its only 39.9p a litre.

 

I wouldn't do a conversion on a car that I owned though, I only buy a car with it fitted, as it would take years to make a ROI.

 

Gaz.

lpg supra anyone?:)

 

I met someone at a Shell station that had a LPG TT Aristo with just as much power as normal fuel and twice the MPG. He told me they were gonna do a Supra soon but that could be bull.

yeah there is a TT aristo on the aristo forum, he has a nice set up and seems stable.

As far as OEMs are concerned LPG is a pain because you have to run two completely different fuel systems from tank to injector. CNG (compressed natural gas) is very big with the taxi drivers in China because they have big gas natutral gas reserves. When I was out there, the oddest thing was that there looked to be about as many gas powered cars was diesel cars over here, and vice-versa. There didn't seem to be much diesel infrastructure.

 

IIRC one of the gas technologies (LPG or CNG) has some legislative problems in Eurpoe because one is heavier that air and can cause a fire hazard in an underground carpark. At least that's what I heard froma colleague. Might be baloney.

 

At the end of the day gas is still a fossil fuel, so there's no way to make it "carbon neutral" - which is where the effort is going to start heading. Ethanol and methanol are much more friendly and (provided you get your injectors and seal materials right) can use largely the same fuel system as a gasoline car.

 

Ethanol or methanol are the biggest

its true, and its lpg :) you can sometimes see the "cloud" on a cold day just after you unplug the gas pump :blink:

I know of someone on the SX owners club who converted his S14a. Works very well in performance/turbo cars as LPG is a higher RON than most petrols, somewhere in the 100's.

 

Ive always been sceptical about what the government will do, i can see them waiting for enough people to convert, then jacking the price up as a nice lill earner!
