No Martin, Just the same fuel I always use, and the engine started right up in a couple of flicks.
In any case, I only use two diesel fuels: My "fixed compression" fuel, which I have to mix myself, and English commercial "Sport" fuel, that I use for everything else (i.e. everything other than fixed compression).
Anyway, you've given me a good idea. Most winters we do get a bit of snow, so I'll keep a watch on the weather forecast and try to get a good video...
