On the other hand we have been running an lpg car for a number of years now, had 3 converted and bought one used already done, a Mitsi supplied new with makers approved conversion, and a poor conversion it was too.

You have to choose the right car with a suitable place for the tank, and make sure you get a good quality flashlube dispenser system fitted to the vehicle.

German cars especially take well to the conversion as having hard valves and seats are less likely to suffer VSR (valve seat recession) than some others, also avoid direct injection engines as these are not generally suitable for conversion.

Find the right converter, sadly i believe the excellent place at Featherstone no longer converts vehicles nor does Toby in the depths of Worcestershire, and this is happening all over, only a hard core left of converters, we haven't had any issues finding cheap lpg supplies (currently paying 56ppl) but i wonder if bp garages are trying to find an excuse not to sell it any more as their prices are stupidly high in many cases so their sales must be minimal.

I suspect the present LPG car converted last year will be our last, unless something happens to reinvigorate the fuel, there may well be nowhere in a few years to get the conversion done or service/repair current equipment, only the east europeans will be users mainly because they can get cars converted at home when they visit for less than half the cost here so the sums make more sense.

Do remember the lpg system will want an annual service. Not so much the cost but will you have to pop back to say Romania every year or 12k miles? My 2p find a UK converter and pay the extra cost. I gave lpg up because I got fed up with the local stations "running out" or "the pump is broken" etc. I do advise to get the biggest tank you can fit. I had a toroidal tank and it gave 150miles. Dont forget you might pick up a already converted vehicle. I'd also agree with other posters..a pumped flashlube system is a must. Best of luck.

Sadly LPG use has been declining because of government decisions just concentrating on low CO2 re tax(good for diesels), killing off grants and bringing in the LPG fuel tax escalator.

Is there some kind of multi-party under-the-counter agreement to always back the wrong horse re automotive environmental policy?

Lean-burn?

Tax concessions for diesel?(KNOWN to be an environmental hazard at the time).

The infamously stupid scrappage scheme?

Can't all be accidental, surely?

LPG-injected diesel seems to have a lot going for it. Was very big in Australia for a while.
