£12 is not bad at all when you think how much 1000 miles of NOS would cost,,,
I asked about the weird looks since I don't know why but here in italy almost all lpg pumps are served [I mean the guy does the job for you] and you can't fill up by yourself,,, maybe they fear dumb people makin a mess and blowin up something, I don't know,,, anyway, I'd really like to see the guy's face when one asks him to fill up a diesel,,,
