Approx cost of lpg conversion would be about £1000 fitted by an approved converter. It took me 4 years to break even on the cost as the motorhome mileage was fairly low (6000 miles per year). I think that I would be reluctant to convert an old vehicle for this reason. I have had two vehicles converted (at one year old) and did not regret it.
Hope that this info might be of use

 

Hi,

This is a regular question that pops up every now and then, so a search through the archives may get other replies. Anyway, Its not a conversion to take on lightly as there are many pitfalls. Fitting diesel engines years ago was popular due to the fact diesel was much cheaper than petrol, however these days petrol and diesel is more or less the same price.

You’ll find it far more cost effective to have your existing engine converted to run on gas as it will then be as cheap as something like a Metro to run, thus giving you a cost effective payback.

The gas option is still the best, even if the engine needs a rebuild. The trouble with Diesel conversions is that they are not always successful, especially if the original vehicles gearbox and or differential is retained. The overall gear ratios in petrol driven vehicles are different to what would be used with a diesel engine as petrol engines rev a lot higher. You can quite easily turn a superb vehicle in to a pig of one to drive by going the diesel route. Sorry to be so negative, but you do need to know before starting.

 

Thanks for the advice i will pass it on to my dad :wink:
