RE: Diesel Fuel Addtives

Haven't seen the fuel additive question for a few months.

But I enjoy the conversation.

If you have a water-in-the diesel fuel issue, then you need to get the water out (drainage) and keep it out.* If there has been enough water in your diesel for enough time, you need an additive (such as Biobor)*to kill the bugs, then get the skeletons out (drainage/filters/tank cleaning).

Otherwise, no additive is needed or generally recommended by engine manufacturers (that I am aware of).

I have owned/operated*2 recreational boats for the past 38 years and thousands of operating hours, and other than a one-time use of an additive to kill*bugs, no other additives have been used.* I have also operated commercial vessels for thousands of hours without any*additive being used.

No. 2 diesel works great, and is really all that diesel engines need.* If a boat owner has a belief that an additive is needed, then an additive is needed.
