Smoke this morning

Did anyone else's diesel produce blue smoke this morning? It was about -2 degrees. Just wondered if this is normal or sign of a problem. I assume it's just the cold weather...

It's burning oil, How Blue was the smoke? (stupid question I know) Was it more grey than blue?

It wasn't massively blue, or particularly thick. I suppose it could be described as a greyish blue.

Could be a possible problem with the preheat system.
