I knew someone who got a converted Rangy, he eventually chucked it due to lack of mileage range, lack of supply pumps, and it was a bit thirstier with less grunt, and thats without him paying for the conversion either !

I think you need to do the sums carefully

This a Jeep Cherokee 6 cyl? I'm curious what mpg are you getting? I ran one here in Canada and got arounbd 13-14mpg. So I converted by trading it for a diesel!

I almost bought an LPG Range Rover. The main reasons for not doing so was the lack of LPG pumps (the nearest one to me is 10 mile away) and the increased risk of something going wrong with it.

I bought a Diesel Grande Cherokee 2.7. I get 29 MPG around town, about 34 on a motorway and 25-26 when towing the RIB (mostly motorway).

If my company did not pay my fuel then I would get a 1000 Litre container of bio diesel delivered.

So, do the math on having LPG installed against trading in for a diesel, dont forget to add in the petrol use for when you can not get LPG.

pretty much as i thought, conversion cost would be just over 2 grand and the price of lpg is starting to rise slowly, im returning 20-22 mpg on a run towing the rib. which compared to some of the 4x4 diesels out there isnt that bad. and as i only need to have a 4x4 to tow the rib then i might be better of using the 2 grand to another 4x4.

Yes I am, have been running my 3.5 Defender on it for 4 years now, It still has the option to run on petrol at the flick of a switch but its on gas 99 percent of the time. A modern conversion shouldn't give any noticable performance loss if done well but there will be a slight loss in overall mpg.
That said I bought the vehicle with the conversion done and my lpg station is only a mile away. Think I'm paying 45p litre.

Hello all,

Holland is one of the country's of LPG. Look at the www.Jeepclub.nl site and their forum and ask there the question. Here in Holland the goverment also knows how to steal money from the fuel. LPG also rising sky high. (+/-€0,55cnt a Ltr)
Be careful With the installations, get proper info from them, also from dealer.
http://www.prins-lpg.com/nl/prins/ is for Jeep one of the best.
I know because a friend of my was one of the test pilots with a Grand Cherokee 1998 mod v8 5.9 (direct injection lpg ) That model wouldn't run on LPG without giving error messages from the computer but they fix it. Jeep Dealer strongly didn't advised LPG for that model. board computer didn't accept it.
much o problemo's

Landcruiser

I converted a Toyota Landcruiser 4.7 V8 to LPG. I got very frustrated with the conversion because I could not get enough Gas through to the engine if I was climbing a hill or overtaking, as soon as you put your foot down the engine switched from Gas back to Petrol as the LPG system could not physically pump the required amount of Gas into the engine. I then had to pull over, switch the engine off, then back on again to engage the LPG system. Real shame as the Landcruiser was a fantastic vehicle, plus the range on a 90l tank of gas was really disappointing. Certainly did not justify the conversion cost, should have just put that towards the fuel cost to run it.
