Thanks for the reply - I do not intend to take any chances with the car re LPG or anything else. I do love it in it's full orginal glory and want to keep it that way despite the pain of such a small tank for such a large vehicle. I did also ask the Lexus Tecdoc desk who have just pushed me to the local dealership who in actual fact gave the same response as another club member that related to the hybrid stop start system rather than the the blown head nightmare that another member has endure. So no LPG for me. Thanks. Phil.

Tony, thanks for the reply and no worries about bluntness at all I didn't see it that way and to be frank am impressed that the club has memebers who are will ling to share the nightmares - as well as the good stuff. Thanks again.

Thanks for your response, I have always had a niggling doubdt about the effects on any interchange that takes place between the engine and the batteries so I guess it is back to Lexus for the final vote.

I looked into this a while back & came away with the conclusion that it wasn't as easy as it sounds & probably problematic on a Hybrid. The reason is simple, each time the engine starts it has to run on petorl first & then switch to LPG. As you know, even on long runs down the motorway, the engine switches on & off as required & most of the time you aren't even aware of it, so unless you have an automatic system to work with the Hybrid controls you may well run into problems. Personally I'd seek the advice of Lexus technicians before you spend £1800, because the Hybrid parts of a 56 plate will still be under warranty & engine rebuilds are VERY expensive, probably more than the LPG conversion due to high labour rates. All that said if you have a wonder-system that does work let us know, for some, as you observe, the cost (& loss of the spare wheel?) may well be worth considering.

Thanks for your comments it certainly has put a nail in the plans I have. I think that consensus seugeste that I need to speak to Lexus directly before carrying on with the idea.

Paul, Thankyou for the prompt response and the mention of the lubrication for the valves which confirms something the supllier has mentioned too. I guess the final bit of question I have relates to the fact that as yet I have not spoken to anyone about the conversion of a RX400 Hybrid although I think the engine itself is the same as yours....51p eh? that is cheaper than anywhere else I have spotted! Regards Phil.

Hi, does anyone have any information on RX400h LPG conversion, I have looked into the idea and am getting close to adding this to my 56 plate. The supplier concerned is of good repute and experience with great workshops etc at the same time he is convinced that this is a straightforward job. The cost should sit around £1800 and will pay for itself in the first year at my current mileage of 30k per yr. hardly suprising when the price of LPG is 50% of petrol. Any thoughts folks?
