Any chandlery or auto supply store will have a rack of "fuel treatment" bottles from different makers. And any brand name product should work reasonably well. They contain additives designed to make the fuel (gas or diesel, whichever they are for) more stable for long-term storage. For diesel they will include a biocide to keep critters from growing, and probably a cetane booster because diesel loses power as it ages, and I'm not sure what else. For gasoline, the additives are designed to keep things in suspension, and prevent/compensate for the evaporation of high end fractions. Exactly what each one is and what it claims to do, is not my department.[g] But for fuel that will be STORED unused for long periods (i.e. 6-12 months or longer) they all seem to make a big difference in how well that fuel burns and how it causes fewer problems.
If you are going offshore with the intent that your fuel may be stored and unused for over 3 months, pick a brand name that you recognize (one of the petroluem companies or chemical makers as you please) and use the product according to the directions. With no access ports you are limited as to being able to inspect or clean, all you can do is hope you've got enough filters and the tank itself is clean to start with.
Personally I think anyone who builds a marine tank without inspection access ports should be keel-hauled, the old fashioned way without antibiotics on a fouled bottom. And having heard a "reliable" diesel sputter and die once too often, I no longer trust the fuel from ANY pump, I want to see it pumped through a "baja filter" or other filter strainer which absorbs moisture and dirt, and lets me watch what is coming in with the fuel.
But that's just me--I hate bleeding diesel fuel lines, I hate the smell of diesel, I have zero tolerance for anything "diesel" that is less than 110% reliable. I'd rather wait for the seasons to change and a breeze to come up.[vbg]
Ethanol. Gasahol. I can't wait for the history books to finally write about the greatest agrobusiness boondoggle of the 21st century! Good point, the ethanol can be problematic, as much as the changeover to lead-free fuel was. I want gasoline in my gasoline, not vodka! Aside from the damage it can do, I can't think of any reason for it unless you own Archer-Daniels-Midland stock, because whatever it gains, it immediately loses since you need to burn 10% more of it to make up for the lower energy content. And for this I pay taxes?!
