The converter I am going to use is AJC in Hythe who do Prinz systems with and without and claim no problems so far with both choices. I asked at Discount Trucks our local experts and the have had Bongos in with and without and no problems with the conversion either way. They reckon the valve seats are fine with LPG anyway, plus you still use some petrol.
So its a bit of a guessing game, will valve seat wear or gummed up lambda sensor get you first

So far I am leaning towards without flashlube, having none on my Jeep which runs perfectly on LPG which seems to have cured its ongoing lambda sensor problems. Its an elderly Bongo, 95 V6, so will it be any different from the newer ones like Hayden's which run fine without flashlube. The milleage is around 80 thou in miles and the emmissions are really good.
What are the experiences of others with LPG conversions. Bet its a 50/50 split like all the advice I have had so far.
