Just read these posts and am now realizing just how much of a prob I have with my Lpg conversion! Bought a Range Rover vogue HSE, 4.6 V8 in December and have had it back to the converters 3 times now. It runs ok for a week or so then Lpg consumption goes through the roof (4.5 mpg!). It's cheaper...

Just noticed you have a 4.6 LPG. Can I ask roughly what mpg you're getting as I bought one that'd just been converted in December and was told it would be uneconomical for the first 1000 miles until run in then would be ok.....it isn't! Am getting approximate 1.5 mpg using LPG....help!
