punto's are a pain in the arse to put petrol in, have to trickle it in or it clicks off, takes about 5 minutes to put in a tank, and when its the middle of winter its bloody freezing.
the other week actually, was putting petrol in and my mate asked me the same question the OP asked, he didnt understand why i put a random 35.76 or something in.
am i the only one that squeezes as much petrol as possible in? i go past a good few clicks until it wont let me put anymore in at all, so i completely fill it up, dunno why.
