definately worth it. my dad has an lpg astra. soooo cheap
i did part of my aprenticeship in an LPG place.
MPG does go down. but, you pay alot less for fuel so its better.
Going rate is around £1300. dont go with a mixer system, go with an MPI(multipoint injection)

ah no wonder! lol
ive never had to produce a certificate for insurance purposes...tho, its on the business insurance, so whether that effects things i dnt know.
check that out first, and then if you/they are confident at drill the inlet and some simple plumbing work, then go for it.
you can buy the individual parts on ebay...condensor, gas-distributer, nozzles...all new....plus a second hand tank=cheap install.

When the price of crude oil went up a few months ago petrol here got up to $1-40 (60p) a litre so the government introduced a rebate of $2000 (800 pounds) to anyone who wanted to convert their car to LPG. LPG only costs 50c (20p) a litre here. But you use about 10-15% more litres than you do of fuel. So even with the price of oil and petrol back down LPG is only about half the cost of lpg per kilometre. There are issues though with the weight of the LPG kit, the tank using up a lot of your boot space, proper fitting of it so its not a fire risk especially in a crash, and issues like having to start the car on petrol then switch over, with some risk of backfiring and blowing the air cleaner off if you start it up again almost immediately if you've turned it off while you're running on LPG. Here its available in the cities, but you can have trouble finding it in the country. Which is a problem if you've bought an LPG car like the ones Ford sell new that ONLY run on LPG.
The really big cost saver though is running your car on natural gas. Its cheap. Here its the equivalent of 5 cents (2p) a litre. Range is fairly short, so its OK for communting. You've have to switch back to running on petrol for trips. And its harder to find someone to do the conversion. You refill at home overnight with a compressor unit that connects to your home's gas supply.
But whether its LPG or NG the gas stuff doesn't fully tie into your engine computer. So some functionality of it doesn't work. Like stability control.
The problem with doing a Clio is that the tank uses up the boot space - perhaps there'd be room underneath in a 182 - and finding room under the bonnet for the hardware there. Same with most small new economical high-tech modern cars. What I found was a company here is trying to get a gas conversion kit on the market that will work on either LPG or NG and does fully work with your engine computer. It uses the signal from the ECU to each petrol injector and feeds it into a converter that remaps it to the approriate voltage for the correct duration for the injector so the factory ECU thinks its controlling the standard injectors. They make up a car-model-specific spacer for the intake manifold that their injector fits to.

Hydrogen would make an ideal race fuel. The main problem comes from storage...not in terms of safety, but in terms of practicality and weight for eg. To be stored as a gas it would require 200bar=very heavy tank! Also because its such a low density, the volume required increases, so when you compare to say petrol, you need significantly more volume per mile...again=more storage.
Theres other issues which would need to be considered for use on a road car. One off the top of my head is the changing of propeerties within the lubricating oil which is often experienced due to the low density of the gas, and so increased blow-by. This sort of contamination could be detrimental to a road cars life, who's oil changes can often be quitew a period apart.
As a race fuel, it could be very advantageous...increased detonation limits for example would allow massive inlet pressures and Cr, allowing for optimised output. On the downside, again storage. There are capillary materials that have been tested which "absorb" the fuel and so reduce the volume of storage considerably due to increased density. The problem with these were, its takes 30mins to re-fuel....hardly race-winning pit times eh?!
