now then, never thought it would get this cold!!...was chatting to an AA repair guy at work hes been out to loads of breakdowns over the last few weeks and hes had one or two cases of diesel fuel waxing up!!no particular make of vehicle ,just worth remembering if you get the old girl packng up on you when its below freezing it could be this , he said the car(s) had been ok and driveable at minus 15 but packed up at minus 18 !! the weather we have been having lately isnt that wide of the mark !
