Since this is the first year I have had a diesel boat to store, I am looking for some pointers on this. Should I run it low on fuel and then refill it with winter diesel? Is all of the winter diesel ultra low sulfer, and if not will it cause an issue with my motor (common rail injection)?
Ideally I would like to be able to run my furnace on occasion during the winter, but this is not essential. It runs off of the main tank. Does anything happen chemically to the diesel if I leave it full of summer diesel for the winter, or does it just gel and then turn to normal when it warms up? Do you need to leave some volume in the tank for this or does it stay about the same volume gelled?
