Due to personal circumstances, our cruising this year has been limited to a rather narrow geographical area. This has also meant that twice recently, we have topped up with fuel at the same location.
Now the engine and Webasto heater have performed perfectly, but our Lockgate Refleks stove has not. Even on the highest setting, it barely functioned and created a lot of soot. I cleaned it, with no change. So, having run down the tank and filled from a different source, tried it again. The performance was much better, then better still after a further top up from another high volume source.
My conclusion is therefore that I obtained fuel of a lower Cetane rating than normal, during our restricted cruising. Anyone else had this?
