Unusual to have larger vehicles on LPG. Are you sure it's not CNG?

I'm not certain of that. All their vehicles had signs on the side saying
powered by LPG. I think.;-)


There's quite a number around - seems to be some specialist converters:

I had one of the early versions of these systems on my 200TDi Defender.
The Savings you achieve depend entirely on the relative price yo are
paying for diesel and LPG. They are not LPG conversions in the way that
a petrol engine is converted, they introduce the propane into the air
intake and fool the ecu into reducing the amount of diesel needed.

We played around with it - and blew up the engine in the process. You
could achieve some quite good performance results if you put in enough
propane and ignored the emission and efficiency.

We used o find Range Rovers to annoy to pace ourselves against not
racing of course, that would be illegal on a public road.
