Not long had a W140, what a lovely car they are. heavy on the juice but had expected that. Thinking of a LPG conversion - any thoughts by anyone who may have done it, with the increase in my fuel costs would only take 12 months to break even. Trouble is I don't want to spoil anything !!!!

It is very rare that I hear of any Mercedes running on LPG without issuses. I suspect that a W140 would be a particularly difficult nut to crack as well.
I'm not saying that it cant be done but I would suggest walking away from any fitter that doesnt have a strong track record of successfully doing this on W140's.

I think it very much depends what system, what engine and who installs it. I must say the system in my '91 GES300 is faultless. Had it four years no problems whatsoever.
OP. Where are you based?

There have been some very encouraging posts over the years, regarding Mercs with LPG.
For me this has come to the fore with my own Mercedes 124; because of
the biofuel issue.
It is a known fact that biofuels cause corrosion of the components in the fuel system/circuits of older vehicles, and those which were not designed for such additives eg. my 1995 124 car.
In response to lobbying by motoring organisations and car clubs etc, the introduction of the 10% level of biofuel has been delayed (postponed?).
Nevertheless, the current 5% biofuel is still causing damage, and will result in likely need for expensive parts replacements in future.
That's if the parts are still available then.
Now, if I were to run the car on LPG it would provide a solution to the problem.
It is a know fact that LPG is a cleaner fuel than both petrol and diesel, so you would also be doing your bit for the environment as a bonus.
Other countries have made greater use of LPG with much success.

You won't have a problem with a LPG conversion on your car. Most people who face problems don't maintain the system well enough.

Just read that thread and realised that's the same car I almost had repaired myself. After it sat in our yard for a year we flogged it on eBay cheapish.

Ford make LPG only or duel fuel cars from new. A Falcon is close in size to a 140.

I looked into lpg for my c140 years ago. Some people reckoned it would just work, others knew different and had actually done some w140s..... It is possible, but avoid anyone who 'thinks' they know what they are doing.
