Calibrating oil for winterization?
My Vetus manual recommends running a litre of "Calibrating" oil (which it describes as "a fuel with preservative properties") into the engine from the fuel intake as part of the winterization process. This is recommended in addition to fogging the cylinder heads.
Does anyone know where this is sold and if this is necessary? I was not able to find any.
