One of the problems with auxiliary diesel sailboats is that the engine is run so little. This means that it takes you 3 years to empty a fuel tank. Current wisdom says to keep the tank full to minimize condensation, which results in algal blooms in your tank. My main question is, how well does diesel fuel age, when you're only replacing a third of it every year. I assume that a biocide such is 'Bio-Con' will prevent that black crud from developing in any water condensate. Any comments?
