Mine is a 2007 XC90 with the 3.2 engine running a multi-point injection Zavoli LPG system w/ Flashlube. 70l toroidal tank where the spare wheel used to be (about 54l actual capacity).
The car is about to tip over 200,000 miles and has had the LPG system fitted for at least the last 100k. The engine runs beautifully on LPG with no noticable loss of power and no problems with valves or anything (Flashlube system helps there).
I've worked out that I get the money equivalent of about 35-40mpg (driving all the over the country, paved and unpaved roads, and most definitely not hypermiling). Car still runs perfect on petrol as well, so with the original full petrol tank plus the 55l of LPG where the spare wheel was, the range is excellent, which is important to me.
If somebody had already decided that they definitely wanted an LPG XC90 then I wouldn't hesitate to recommend the 3.2. I think it's a lovely engine that's all fairly low stress and doesn't munch gearboxes like the T9.
However, a good LPG conversion isn't cheap, and there steadily fewer and fewer LPG filling stations around the country (Shell just did away with virtually all of theirs). That combined with the push towards electric and so forth would leade me to believe that converting a car right now, except in very particular cirucmstances, would be a poor investment.
