When I was a mechanic on the lorries ( many years ago ) we added a gallon of petrol to the diesel tank to stop the fuel from ' freezing '.
I discovered later that the fuel didn't actually freeze , the wax which in previous years had been removed to make candles , separated from the diesel when it reached a certain temperature and blocked the fuel lines.
