Does anyone know anything about LPG conversions? Went to fill up the other day and the bloke in front of me paid around £20 for his tank of LPG compared to my £50.43 for petrol. Which got me thinking, is it worth it? I used to work with a bloke who had had his converted to LPG and he reckoned you couldn't tell when the engine switched from petrol to gas (fires up on petrol, the automatically switches over) and from riding shotgun, it would appear he was right. HOWEVER I've also heard that it can make MPG suffer and sap torque and power somewhat. I've done a bit of looking into it but can't seem to find any reliable/impartial sources of info. Has anyone else had the convertion done/know someone who has and can give me some advise?
