i've had several vehicles on lpg, loved it, so cheap to fill up, but found that ford zetec engines don't like it, had 2 mondeos and both in the end wouldn't start on the started, but would run once bumped, started was spinning engine over fine, but compression was to low to start, think the lpg had burn the valves out, old pinto was fine, had p100 with old pinto in it and it just kept going, i would have another lpg car in a heart beat, thinking of converting my old american pick up to lpg for next time i'm in the uk
