In my case: No I dont. I filter to 1um, no further processing. >Also, any comments from long-term users of two-tank systems - are >they really inferior to Elsbett-type single-tank systems? I think 2-tank is far superior. You have one tank with industrially managed well understood diesel, and an ALTERNATIVE tank with a liquid that may contain fats, acids, water, salt, sugar and anything else it met in the fry pan. So I drive almost always on used soy oil but can switch to a well defined fuel any time. Long term is in my case about 70,000km. >>Acid contamination can and will damage your engine. This is the second reason for 2-tank. Shutdown and startup on diesel prevents the corrosive WVO from sitting in your engine while the car is parked - which is the overwhelming part of a cars life for most of us. My setup does not work well for short distance.
