Each of the engine manufacturers spec their fuel requirements D975 or EN590. As long as the fuels meet the specs no additives are required. The ulsd refining process removes the lubricity and it it must be added back using additives by the supplier.

What I worry about is I travel to many islands and up and down the east coast. it can only take one bad batch of fuel with subpar lubricity to damage an engine. If the correct additives were not blended in fuel I took at Staniel cay or Lucaya or some other unknown marina I worry.

Same thing for me with biobore. I use it from time to time or when my fuel will sit. Have never had an algae problem. But worry about getting some water in fuel when the tank in treasure cay gets low since they are not my regular supplier
