I have a 2003 Windy Scirocco 32 with a twin Volvo Penta KAD300 installation. The fuel tank on the boat is of aluminium and 520 liters. I put the boat on shore from end of September to app. end of April and I leave it with a full tank to minimize condensation.
I was first thinking of adding a diesel improver additive with water emulgating properties when filling the tank before winter storage. But then I got uncertain if this is wise. Any water emulgated in the diesel would leave the tank, travel through the water separators without falling out and into the Bosch rotary HP pump and the diesel nozzles. Could any water emulgated in the diesel cause corrossion in the fuel system?
The diesel here in Norway has a biodiesel content of 2-5%. So I was thinking if it maybe would be smarter to add 2-Stroke oil to the diesel on the last fill up before winter storage? If yes, mineral based 2-Stroke oil or Synthetic? And at what concentration? I can also add that there is no DPF or catalysator on the exhaust side of the engines to worry about getting clogged.
