Chris Wilson Posted January 3, 2008 Share Posted January 3, 2008 Do people do this? What are the gotchas? How is it done, and what are the cost savings? All in the interests of knowledge, I wouldn't dream of trying to thwart the chancellor. Thanks Quote Link to comment Share on other sites More sharing options...
Carl_S Posted January 3, 2008 Share Posted January 3, 2008 I run my skyline on lpg, its fun that the tax is already paid on that fuel. central heating gas? Is that like british gas gas, the stuff that heats the hot water? wonder if there is anyone here who has had their supra TT on LPG.. lol Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 3, 2008 Author Share Posted January 3, 2008 Gas as in Calor Gas, in the big outdoor tanks. I have had a MKIV TT in here with a multi point LPG conversion. I remember it well, the underbonnet was a nightmare of pipes and solenoids. I didn't get to drive it on LPG though, so can't comment on how it went. My wifes Jeep 4 litre has LPG single point conversion, and whilst it's noticeably more sluggish on gas it's just fine, and costs the same to run as if it were a diesel version. Downsides are a huge gas tank in the boot, making load carrying space a joke, and if you don't feel brave, and carry the spare tyre, too, a small hatchback has more load space. I use it mainly for towing and on the land though, so it's not a big issue. I chuck the spare in the trailer Quote Link to comment Share on other sites More sharing options...

Just wondered if anyone here had bothered. Any yeah , I must make routine jobs on a supe's engine bay area a bit of a mare, and rack up labour costs for the client. Calor gas eh? One bad thing about LPG is that it smells like rotten eggs. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 3, 2008 Author Share Posted January 3, 2008 I would think you'd need some sort of high pressure decanting pump to move the gas from the central heating storage vessel to the car's gas tank. I am curious as to how much central heating gas is a litre compared to road car LPG. Quote Link to comment Share on other sites More sharing options...
Kranz Posted January 3, 2008 Share Posted January 3, 2008 For CNG (Compressed Natural Gas) there are a few systems on the market but they are very very expensive and difficult to install and certify due to the extreme pressure the gas needs to be compressed & stored at. The pump is something like £5k to pump it at home and the gas tank in the car is carbon fibre with some wierd matrix inside using something like coconut shell last time i heard. Its not really practical at the moment although some fleet tests are being done. I worked on a CNG police car demonstrator at Tickford back in 1993. Still hasn't caught on.

Chris Wilson Posted January 3, 2008 Author Share Posted January 3, 2008 No, no, I am talking central heating gas as stored outside in tanks, very common out here in the sticks away from gas mains! AFAIK it's exactly the same stuff as Autogas, but doesn't have the same duty on it. Quote Link to comment Share on other sites More sharing options...
hogmaw Posted January 3, 2008 Share Posted January 3, 2008 Is it the same stuff? LPG is liquid (ie petroleum gas under pressure) - you sure that is same as calor gas? Besides, isn't LPG cheap enough as it is? It's 52p a litre where I live Quote Link to comment Share on other sites More sharing options...

hogmaw Posted January 3, 2008 Share Posted January 3, 2008 How do you get it, under pressure, from the storage tank into the car? Quote Link to comment Share on other sites More sharing options...
adam bell Posted January 3, 2008 Share Posted January 3, 2008 52p a litre for autogas wasnt long ago it was around 35p a litre seems to be going up quite quick. if more people get lpg that will soon rocket in price as well. Quote Link to comment Share on other sites More sharing options...
hogmaw Posted January 4, 2008 Share Posted January 4, 2008 True but at the moment it's still half the price of petrol, for the same performance. Quote Link to comment Share on other sites More sharing options...
JustGav Posted January 4, 2008 Share Posted January 4, 2008 Strap the bottle to a roof rack, and stick a green compressed gas sticker on the car. Job done Quote Link to comment Share on other sites More sharing options...
Simon Posted January 4, 2008 Share Posted January 4, 2008 Chris, I investigated this when I switched from oil to lpg at my home. You can get a proper fuel dispenser unit fitted but because of the tax diifferences between lpg as road fuel and lpg for heating and cooking you would need two tanks. Plus iirc, there was a minimum number of vehicles needed before calor or shell would install a unit. Quote Link to comment Share on other sites More sharing options...

AFAIK it's exactly the same stuff as Autogas, but doesn't have the same duty on it. Ahhh, propane or butane (or a mix of both as Autogas is). IIRC its normally propane. I ran my XJ40 on bottled propane & pumped it at home. Filling from a large household tank is the same. You just need a pump fitting to the feed pipe (liquid draw not gas as is normal for household use) and draw it off there. If you're going to use it on the road then you'll need to have a flowmeter fitted & declare how much you're using, then pay the duty direct to Customs & Excise Your supplier will be able to advise you on a pump, meter & the cost to supply & fit.
