I'm going to take my Cummins turbo-diesel powered trawler on the Great
Loop next summer, meaning I will be in some warm places where things might
grow in my tanks. I also read all sorts of ads indicating I need stuff in
my fuel to clean injectors, increase cetane, clean carbon, reduce wear,
increase mileage, etc.

Is any of this true? What do I really need to add to my fuel?

A trawler will probably burn the fuel fast enough for it to not be a
problem. However, on my sailboat, here in N. FL, leaving diesel in the
tank without a biocide has caused me some problems. The fuel will soon
look like ink. So, I would only go with a biocide if it was going to
sit for any length of time.
