When I had my gas boat I would stabilize in the fall but never bothered with anything in season since I went through 4-6 full tanks so the fuel was always pretty fresh. Never had a problem.

But now with much larger (400gal total) diesel tanks I anticipate filling up maybe twice per season (I hope!). At any rate, what are thoughts on adding additives in season? I know I don't have to worry about the ethenol issue but I also know diesels are very sensitive to clean fuel and there can be issues with water as well as organic growth in the tanks.

So, do you use or recommend a diesel fuel treatment with each fill up, and if so, what is the preferred kind/brand?

For what it's worth, there are a lot of people who swear by Marvey Mystery Oil. I know it's not a stabilizing product, but neverless, highly recommended by many people.

I've used the Startron additive for 3 years without issues.

Main thing is to keep your filters clean. I change the primaries at least once per season and I keep a spare set on the boat in case of emergencies.

I too use Startron and have been using it since it was originally Soltron (~10 years). Stopped the diesel soot on the back of the boat and have had zero fuel problems.

Interesting on the soot, because I do get some of that aft of the side exhausts...

Same as Catpn Bill1.

Biobor JF for the bugs and Pri-D to preserve the quality of the fuel.

My racors are clear and the filters stay nice.

I wish Boatfix would start selling Pri-D. It is good stuff.

I use Sea Foam for reduced sooting and general keeping tanks clean and free of water.

I use BioBore JF in the fuel to prevent growth and Startron for winter layup or longer periods of no use.

I don't use anything if I'm running through the fuel in a couple months time. I've never clogged a filter, had any issue with "bugs" and my fuel tanks stay bone dry, despite the fact that I rarely keep them full. Truth is, 99% of the stories you hear about diesel treatments are rubbish. "Agae" does not really grow in diesel because of water, its asphaltines which are caused by old fuel, mostly because people are always carrying around way more fuel than they will ever burn and it causes them to wind up with a lot of aging fuel breaking down. They do this because of the often repeated stories about condensation and needing to keep your tanks full. More rubbish. Make sure your tank vents are directed aft (not taking on water through spray). Ensure that your fuel fills have intact sealing o-rings and concentrate on cycling through the fuel you have on board. Make a point of running the tanks low enough to splash up sediment in the bottom and routinely change out your fuel filters whenever you stir up the tanks when a little low. This way, wtshtf, you will have fresh fuel, clean tanks and little chance of plugging a filter unexpectedly.

Recently I've run some Stanadyne through the tanks to eke out a few more hours on a set of injectors I'd like to have overhauled.

I use additives occasionally, but only when I have a specific reason. I never add something just for the sake of adding something.

I'm with Ghost. When I use something, I use Pri-D. I don't know how much difference it makes, but I could get it relatively cheap at Sailorman in FTL, so I use it every so often. Detroit Diesel does not recommend any additives, other than something like Bio-Bor if the boat is going to be stored awhile... what does your engine manufacturer recommend? Best thing is to run your boat, maintain the engines and buy fresh fuel from high volume docks. If you have a soot problem, perhaps your props are over pitched; I never got soot out of my old Detroits until I threw a spare pair on that had another 2" over the regular set.. and then just a very fine coat. Lack of engine PM could also be an issue. Better to cure the root cause than apply band aids.

Why do you need to add anything to your diesel fuel?

The manual that came with my boat included a statement from Volvo (engine) and Bosch (injectors) that in one sentence stated that fuel additives were not recommended, and in the next sentence recommended additives because of EPA rules reducing the amount of sulphur in diesel fuel.

Stanadyne was one of the recommended additives so I've been using it along with Startron.

I haven't had any fuel related problems, but I might not have if I had used nothing.

An Algae-X dealer working on another boat at the marina said that Stanadyne and Startron were "junk" and I should be using Algae-X.

aahh, this is what I love about boats. On some subjects everyone is on the same page and on others, well...

I like the suggestion of checking with the manufacturer. And I appreciate the suggestions about cycling through fuel to make sure it's always fresh. My boat is 20 years old. And I have no idea what might be at the bottom of those tanks. I suppose I could have the fuel polished. That would be a topic for another day. I doubt that any of the more common fuel additives would do any real harm. But I'm inclined not to waste my money either.

As for the soot, I don't think I have a "problem". There was some soot on the aft corners of the boat just back from the side exhaust after running the boat for 6.5hrs on her delivery home. I was not under the impression this was a problem.

A very close friend of mine owns an excavating company and he adds Marvel Mystery Oil every delivery - swears by it.

The way I see it, he has a lot more on the line than us.

I think we have to consider that if your engine was designed when high suphur fuel was the norm and low sulpur fuel is the norm now, something may need to be added just like the case years ago when lead was removed from automotive fuels.

I have heard of all sorts of things being added to diesel fuel (including gasoline) and the person always swears by it, but I'll be sticking with name brand products designed to address an issue.

I've been told that Bob Smith, The TOP Guru when it comes to Ford Lehmans and pretty knowledgable on other brands as well, is an advocate for MMO. Whether just for Lehmans or diesels in general, I can't say.

He recommended it as an additional lubricant for the injection pump as I recall.

I ran/maintained many, many different Lehmans for a total of thousands of hours and never did use the MMO trick. And I can only remember one boat that had injector pump problems. (Weird one, twin engine boat and both pumps failed at the exact same time.)

I add diesel power for lubricity, the lower sulfer content was/is harder on pumps and injectors (so I been told) so I add for that reason.
