Why don't manufacturers give an LPG option from the factory?
Discussion
This is my expert area !!!!
vauxhalls did
They used a system called koltec necam and quite frankly ..... It was rubbish
Because of the poor quality of gas in the UK the injectors used to get clogged up
A new set of injectors from vauxhalls were £960+vat
Yes you read that right
That's with no guarantee that they would work. It could actually be something else that had broken but the injectors were first port of call
Anyway the full price for a FULL LPG system to be fitted and certified is £1400 with a 2 year warranty
So ita cheaper to rip it out and start again
The reason why Vauxhalls have stopped doing lpg cars is because the gas systems were breaking down under warranty and it was costing them a fortune
The did however retry the idea with a BRC system instead which is a much better system. This would be in the car from new but not fitted at the factory
Anyway they did it on a load of new insignias
The system worked perfectly apart from one thing
The new Vauxhall engine is a vvti and burns out seats and valves whilst on LPG
So again back to square one. Only this time the cars all needed new cylinder heads instead
Hope this is enough info :-P

I forgot to mention the flashlube bit
They all had the electronic flashlubes installed burning a bottle of oil every 2000miles and still burnt seats and valves
I also know someone who has converted one with the dripfeed flashlube and even left it running slightly rich on gas and it did the exact same thing

Really cant see the point of LPG. If you cant afford to run the car on its proper fuel then dont buy it! A lot of people say why is your Rangie not LPG and I say to them its not supposed to be. If that was the best option then the car would come direct from the factory like that and would run solely on LPG like a forklift does. It just smacks of penny pinching and people possibly living beyond their means, plus it will eventually ruin your engine one way or another.

Wow, you are awesome! 
I looked at a new Volvo dual fuel car a few years ago - you only got half the normal size tank of petrol & lpg - which meant I'd only make two days between fill ups on LPG (assuming there was a garage that sold it close). Then when I did the sums, it didn't really work out much difference than a diesel for running (though petrol & diesel has gone up a lot since then)
Whats that supposed to mean? I know its stretching it a bit but would you put LPG on a rolls Royce? No you would not even think about it. So why fit it on say a Jaguar or a Seven series BMW for example. I will stick by my guns and maintain that if its that good manufactures would all be jumping on the band wagon and offering it from the factory, but obviously the demand is not there. It only comes into play in the second hand market where people cant afford to put the petrol in, coming back around again to my original statement about living right upto or beyond their means, if they have to scrimp on the fuel what else gets left out? Cheapo ditchfinder tyres, poor servicing?

Had an LPG RR classic LSE in the past. Was in very good condition and the old boy that owned it had the conversion done.
Ran well on it but every now and then it would pre detonate in the plenum chamber and the easiest way for the explosion to escape was through the air box on the front nearside of the bonnet.
Scared the s
t out of me the first time it happened and dented the bonnet from the inside out. After it happening a number of times and getting fed up with the tank in the boot I had it all removed.
Waste of time in my opinion unless they have improved massively. Would need a lot of convincing now to try it again.
