Is there any tips people can give for easier starting of my 300 tdi Disco on these freezing mornings? I have been running on a bio/dinosaur diesel mix, but I've run the tank down as low as I dare and topped up with shells finest super duper diesel. I also covered my engine and battery with a blanket last night to keep them warm, (aah)

. But it still took a bit of starting this morning. Three glow plug heats and four or five seconds cranking with foot to the floor before it kicked into life. Once its started, it starts all day with half a turn. It was -10 here last night, but if it gets any colder, I'm nervous that it won't start at all.
